Help on Tele2, tariffs, questions

In the modern world, there are practically no people left who would not have a computer or other similar device that can connect to the Internet. Therefore, many are wondering how to connect.

If earlier the choice of connection option did not make it difficult for anyone, since it was reduced to only one type of communication via a telephone line, then at present the choice of methods is quite wide.

Anyone, almost anywhere in the world, has the opportunity to access the World Wide Web.

You just have to choose the right type of connection based on specific conditions and place of residence. The following describes the main techniques on how to implement this venture, as well as their advantages and disadvantages.

Existing connection methods

Internet connectivity technologies are advancing at breakneck speed.

The choice of the method of accessing the global network depends on the user's requirements for the indicators of the traffic provided by the provider, as well as on geographical location where the connection will be used.

Of course, one should also take into account the capabilities of a particular user in terms of financial costs for the implementation and operation of the connection.

The classification of subscriber types of connection can be represented as follows:

It is easy to see that the main disadvantage of the second type is that if a single cable breaks, not one client will suffer, but the entire group of users at once.

Next, we will consider in detail each connection method, which is most widely used today in our vast country.

via satellite

A person remote from the benefits of civilization of large cities is not deprived of the opportunity to use resources global network even if he lives in the most remote point of the taiga forest.

The main condition for successful implementation connection is the visibility of the satellite. The main disadvantage of this method is its high cost.

Only for the equipment you will have to pay about 300 hard-earned dollars, and also, when a person finds out the prices for tariffs, he quickly loses the desire to organize his leisure time at current prices. Of course, if Satellite Internet necessary for work, then in the absence alternatives this would be the logical solution.

The method using asynchronous connection provides only one-way access (data from the network is only received). To organize outgoing traffic (synchronous connection), you will need to use equipment at a significantly higher price than that indicated above.

Or, if there is cellular communication coverage in the area, the organization of outgoing traffic transmission via the GPRS channel.

The quality of data reception is affected by weather conditions. During bad meteorological conditions, communication may be completely interrupted.

Via phone

Due to the prevalence of telephone lines already laid everywhere, this connection technology is preferred by many modern users.

The types of connection via telephone should be listed:

1. dial-up;
2. ADSL.

DIAL-UP

This outdated connection method is still used to access the World Wide Web in areas remote from high-speed lines, for example, in the private sector far from the city. Provides for the use of a modem and telephone line.

The main advantage of the method is the low cost of equipment, and the connection is usually made by the telecom operator for free. Also, many users are attracted easy setup connections.

Even the cost of an external modem does not exceed a thousand rubles, and if you use an internal one, then the cost of equipment will be about 300 rubles.

However, the cons far outweigh the pros, as modern man the speed of information exchange over the network is important, and it averages 4 kb / s. But the main thing is that while using the Internet, the phone does not work, as the line is busy.

ADSL

Significantly superior in quality of communication technology "Asymmetric Digital Subscriber Line" or briefly "ADSL". It is faster and at the same time allows you to use a landline phone.

The modem comes with a “splitter” that separates the frequency channels for the Internet and the phone.

If the PBX to which the user is a subscriber has a multiplexer, then he can enjoy the benefits of this method. As a rule, connection equipment is not very expensive, and it is sold everywhere.

The speed of receiving information is already calculated in megabits per second and can reach 8 Mbps.

In areas where there are no other alternatives to the telephone line, providers often inflate the cost of tariffs, therefore, despite the availability and ease of setting up equipment, this technology is gradually being replaced by more modern alternatives.

Wireless

The development of modern wireless communication technologies allows you to get freedom of movement in space and at the same time stay in touch with the Internet.

Standards WiFi connections and WiMax, as well as 3G and 4G, allow you to work in networks at speeds close to a wired connection. The absence of the need for cables and Internet access anywhere covered by the coverage area makes the wireless method in demand.

Given the variety of tariffs and low costs, even owners of a home connection use air communication in mobile gadgets. When you are in the zone of a Wi-Fi signal access point, for example, in public places, communication can be free.

Unfortunately, WiMax has not yet become widespread in our country, since in order to connect it requires laying a cable to the village, and also requires special equipment. Sometimes it is more expedient for users to use the mobile Internet.

WiFi

One Wi-Fi access point is capable of covering a zone with a radius of one hundred meters with a signal.

Users at home have several PCs and electronic devices with the function of accessing the network through Wi-Fi technology.

A home Wi-Fi router allows you to deploy your own local network while simultaneously connecting a dozen gadgets and computers to the Internet that have a built-in or plug-in wireless module.

The router itself is connected to a cable coming from the organization that provided communication services.

Wi-Fi networks are common in parks and in public places. The user is required to have a laptop or mobile gadget with them to connect to an existing infrastructure. In the bulk, at such points, the use of Internet access is free for the user.

Through a mobile operator

Cellular operators provide tariff plans with conditionally unlimited conditions. It is easy to connect to them wherever there is mobile network coverage.

There are two ways to access the web through an operator:

1. Using a cell phone;
2. Using a modem, which either connects to a computer's USB port, or is a mobile Wi-Fi access point.

GPRS

It is difficult to find a person without a mobile phone, which means that everyone has the opportunity to connect to the Internet using a cellular device with GPRS support, even if it has long been more like a brick than a smartphone.

An old mobile phone can be used as a modem, you only need a usb cable to connect to a PC, or this is done via Bluetooth or infrared.

Of course, the speed of this type of connection cannot be compared with 3 and 4G, however, due to the availability of the equipment used and the presence of existing mobile operators, it is still used by users.

3G

The 3G standard already allows you to use the Internet at speeds up to 40 Mpbs.

This type of connection can be used not only by owners of modern smartphones, but mobile operators offer subscribers the option of connecting a computer via a usb modem.

Or purchase a compact router with Wi-Fi support.

It is convenient to have your own Wi-Fi point anywhere, wherever the user is. Some portable Wi-Fi points allow you to connect up to 8-10 devices to them: laptops, smartphones, tablets, etc.

However, when a mobile operator provides a connection according to the fourth generation standard for connecting several 4G gadgets at the same time, it will be more appropriate to use.

4G

In large cities of the Russian Federation, the 4G standard has already been introduced, which provides a speed of 100 Mpbs, and in the future it will be several times more.

Just like in the previous case, the use of usb modems is available for clients.

These "whistles", as people call them, are already loaded with applications for communication with the computer's operating system.

If you want to provide Internet access to several PCs and gadgets at once, then wifi modem, with an installed SIM card of the operator, will allow you to stay in touch even in a country house where telephone or fiber optic wires are not connected.

In the near future, the transfer rate according to this standard can reach 1 Gpbs.

Cable connection

Finally we got to the most popular connection method. A wire is laid in the subscriber's home, which serves as a source of the Internet. There are only 2 types of connection:

1. twisted pair;
2. fiber optic cable.

An optical fiber is laid from the provider to the apartment building, and a twisted pair cable is pulled directly into the subscriber's home. It is inserted into a PC network card or into a router.

Relatively low speed - 100 Mpbs, compared to a direct connection to the optics makes this method a little less attractive, however, the copper wire is less sensitive to mechanical damage and cheaper to replace in case of a break.

Optical fiber

In this variant, the optic is guided to the client's apartment and inserted into the distribution terminal. The technology ensures the provision of several services simultaneously over one communication channel, while ensuring a high speed of information exchange, which is important when broadcasting audio and video.

The technology involves the use of a light channel to transmit information via fiber optics. This circumstance imposes disadvantages, although the advantages of the technology more than cover the accompanying disadvantages.

It allows you to achieve speeds up to 2.5 kbps. To connect, the client needs to install the "Optical Network Terminal" (ONT).

ONT is provided by the provider itself. The terminal is equipped with Wi-Fi, so there is no special need to stretch the cords around the apartment further from the device. This terminal is designed to convert the fiber optic interface to an Ethernet interface.

Terminal models have different functionality, so before installation, you should clarify the possibility of connecting devices via Wi-Fi channel, IPTV, telephony, etc.

To transmit a light pulse through a special cable, it does not consume as much energy as when receiving and transmitting data over a metal conductor.

The downside is that the optical fiber is simply damaged by mechanical impact on it, and the replacement results in a round sum of money.

We will mention this type of connection purely out of respect for history: dial-up access was relevant at the end of the last millennium. To ensure communication, a telephone network and a modem were used, which was connected to the station's modem. The maximum possible speed was less than 58 Kbps, and the tariffs were extremely limited.

It is necessary to talk about xDSL mainly in a historical context, since at one time this technology was a breakthrough, but today it is of little relevance for residents of large cities. The maximum speed available to a leased line user is 24 Mbps. Compared to the dial-up access used before XDSL, the progress is clear. The advent of technology led to the transition from limit tariffs to unlimited ones.

FTTB (ETTH)

FTTB is the next technology after xDSL, which is currently the most widely used in the entire civilized world. The principle of operation is simple: a switch is located in the entrance, which is connected to the station of the Internet service provider. A twisted pair cable is connected to the apartment, which is connected to a PC or a special router. The main advantage is the favorable ratio between Internet speed and cost. The maximum possible speed is 1 Gbps.

The most progressive and modern method among the existing ones, involving the organization of a gigabit channel with Triple Play services. To ensure the connection, a special optical cable, which is connected to the appropriate equipment; converters, sfp module, optical terminals are used. In fact, xPON technology is gradually replacing FTTB, and the business Internet is often used by companies whose work involves the need to transfer large amounts of information.

Since almost every person today has a modern smartphone, mobile Internet is very widespread. It is pointless to discuss its advantages in detail because of their obviousness; the main plus is the ability to have an Internet connection literally “at hand”, the main disadvantage is limited limits. In recent years, the speed has grown significantly: if earlier GPRS and 3G were in use, today they have been replaced by 4G technology. The maximum speed of the latest LTE is 300 Mbps (theoretically); in fact, it is usually much lower. To organize the connection, USB modems and routers are installed.

Satellite Internet is another progressive branch, divided into two subtypes: one-way and two-way. The first - also called asymmetric - involves the use of communication with the satellite exclusively for receiving information, while conventional communication is used for transmission. The second - symmetrical - is more progressive, since it also allows the transfer of information, however, expensive equipment will be required to implement such a connection; the rates are also very serious. The only, albeit extremely significant, advantage is the ability to gain access anywhere in the world (up to the depths of the taiga).

The vast majority of modern devices - TVs, phones, smartphones - have a built-in Wi-Fi module that provides a stable connection to the Internet within a certain area. Large wireless networks are carried out mainly in major cities and in crowded places. The trend is towards WiMAX, which will replace conventional telecommunications due to ease of deployment and scalability.

The Internet is an integral part of the life of a modern PC user. For some, this is a means of communication and a way of entertainment, and someone, using the global network, earns his living. In this article, we will talk about how to connect a computer to the Internet in different ways.

There are several ways to connect to the global network, it all depends on your capabilities and (or) needs.

• Cable connection. This is the most common and easiest option. The provider in this case provides the subscriber with a line - a cable brought into the room, which is connected to a PC or router. There are three types of such connections - normal, PPPoE and VPN.
• Wireless. Here, access to the network is carried out through wifi router a, to which the same provider cable is connected. Mobile 3G / 4G Internet can also be attributed to wireless methods.
• We will separately discuss the possibility of using a mobile phone as a modem or access point.

Method 1: Ethernet

This type of provision of Internet services does not provide for special access requirements - login and password. In this case, the cable is directly connected to the LAN connector on the computer or router.

In most cases, with such a connection, additional actions are not required, but there is one exception - when the provider provides the subscriber with a separate IP address and its own DNS server. These data must be registered in the network settings in Windows. The same will have to be done if there has been a change of provider, that is, find out which IP was provided by the previous one and given by the current provider.

1. First we need to get to the corresponding settings block. Right-click on the network icon in the notification area and go to "Network Control Center".

   

2. Next follow the link "Change adapter settings".

   

3. Here we right click on Ethernet and press the button "Properties".

   

4. Now you need to configure the TCP / IP version 4 protocol parameters. Select it in the list of components and go to the properties.

   

5. Checking IP and DNS data. If the provider provides a dynamic IP address, then all switches must be in the position "Automatically".

   

   If additional parameters are received from it, then we enter them in the appropriate fields and click OK. This completes the setup, you can use the network.

   

6. Ethernet has one feature - the connection is always active. In order to be able to disable it manually and do it quickly (by default, you will have to go to the network settings every time), let's create a shortcut on the desktop.

   

   Now, if the Internet is connected, then when we launch the shortcut, we will see a window "Status-Ethernet", where you can find some information and disconnect from the network. To reconnect, just run the shortcut again and everything will happen automatically.

   

Method 2: PPPOE

PPPOE is a high-speed connection, the only difference from the previous one is the need self-creation connections with the given login and password provided by the provider. However, there is one more feature: PPPOE can compress and encrypt data. As already mentioned, access to the network also occurs using a cable connected to a PC or router.

PPPOE can be managed in the same way as Ethernet - using a shortcut.

Method 3: VPN

VPN is a virtual private network or simply a “tunnel” through which some providers distribute the Internet. This method is the most reliable in terms of security. In this case, manual creation of the connection and access data is also required.

This was an instruction for Windows 10, in the "seven" everything happens a little differently.

Method 3: WiFi

Connecting a computer to a Wi-Fi router is akin to a simple cable connection: everything happens as simply and quickly as possible. It just requires an adapter. In laptops, it is already built into the system, and for a PC, you will have to purchase a separate module. There are two types of such devices - internal, connected to PCI-E connectors on motherboard, and external, for the USB port.

It is worth noting here that inexpensive adapters may have problems with drivers on different operating systems, so carefully study the reviews about this device before buying.

After installing the module and detecting it by the operating system, a new one will appear in the notification area. network connection, with which we will receive the Internet, just click on it and press "Connect".

Of course, the appropriate Wi-Fi network must be configured on the router. How to do this, you can read in the instructions that came with the router. Setting up modern devices, in most cases, will not cause difficulties.

Wi-Fi networks, for all their merits, can be very capricious. This is expressed in disconnections, lack of connection with devices and the Internet. The reasons are different - from problems with drivers to incorrect network settings.

Method 4: 3G/4G modem

All providers mobile internet provide users with modems equipped with built-in memory with software– drivers and client application. This allows you to connect to the network without unnecessary gestures. When connecting such a modem to the USB port of the computer, you need to install the program and run it. If autostart of external devices is disabled in the operating system and the installer does not start automatically, then you need to go to the folder "Computer", find the disk with the corresponding icon, open it and run the installer manually.

To access the Internet, just press the button "Connection" in a programme.

If you do not want to constantly use the client application, then you can use the automatically created connection.

In the event that a new item does not appear in the list, you can create a connection manually.

Working with such a connection in Windows 10 is exactly the same as in the case of a VPN, that is, through the settings window.

In Windows 7, things are a little easier again. Open the list, click on the name, and then click the button "Connection".

Method 5: Mobile phone

If it is not possible to connect a PC to the Internet using the above methods, you can use your smartphone as a Wi-Fi access point or a regular USB modem. In the first case, a wireless adapter is required (see above), and in the second, a USB cable.

For normal operation of the access point, you need to make a number of settings in the phone menu or use a special program.

If the computer is not equipped with a wireless module, then there is only one option left - to use the phone as a normal modem.

Conclusion

As you can see, there are quite a few ways to access the global network from a computer and there is nothing complicated about it. It is enough to have one of the tools described above available, and also to perform if a few simple steps are required.

Good time!

Russia is a big country, and the problem of communication between different parts of our country has always been relevant. With the development of Internet technologies, this problem is partially solved, but even here everything is far from simple...

In this article, I decided to consider various ways connection to the Internet. I do not aim to tell all the subtleties of each option. Perhaps the mission of this article is different - to acquaint you with different options and methods of connection, perhaps to give you an idea to look for something better ...

Simply, at one time I was very surprised how people still manage to "sit" on a Dial-Up connection, when providers with a "dedicated" network (Ethernet) have come to our city for a couple of years now. It turns out that many simply did not know yet that you can connect to this Internet provider almost for free and get dozens of times faster speed!

And so, I conclude my memories, and move on to the topic ...

How to connect to the Internet. Pros/cons of different methods

Dial-up connection (ADSL or Dial-Up)

The most common type of Internet connection. There is an ordinary telephone line everywhere - in almost every settlement (thanks to the country of the Soviets for electrification and telephone installation).

dial-up

A modem is connected in parallel to your telephone set (to the telephone line) (as a second telephone). Further, operators usually have special numbers by which you can access the Internet (by dialing them from a modem, of course).

In general, I note that this method is gradually "dying off" and disappearing into oblivion: in our country, after all, a program has been adopted for the development and laying of a network even in remote areas.

Pros:

1. high availability (you can connect to the Internet even in many remote villages of our country);
2. low cost of equipment (only a modem is needed, which can be found cheaper than 100 rubles!).
3. you can connect yourself: just buy a modem, connect it to a telephone line and set up a connection on a PC.

Minuses:

1. very low speed (up to 56/128 Kbps). Only enough to view pages (you can not dream of downloading files);
2. high price;
3. low connection stability: the connection often breaks;
4. the phone will be busy (when accessing the Internet).

Addition!

You may find the article on how to convert Mbit/s to MB/s helpful. (or why I connected to the Internet at a rate of 100 Mbps, but I only download at 10 Mbps) -

ADSL

This method also uses a telephone line, however, it has a significant advantage: the phone will not be busy while working with the Internet, and it provides much higher speed (up to 8 Mbps).

Of the minuses: a more expensive cost of equipment (than with a Dial-Up connection), and the inability (in most cases) to set up the connection on your own without the specialists of the operator you are going to connect to.

Leased line (Ethernet, GPON, DOCSIS)

Ethernet/GPON

The most common type of Internet connection in all major cities. A cable is laid in your apartment (similar to a television cable, only it has more veins), which connects either directly to the computer / laptop network card or to a Wi-Fi router (to create a wireless network in the apartment).

Pros:

1. high data transfer rate (up to 100 Mbps with Ethernet, and up to 1 Gbps with GPON connection (fiber)). By the way, there is another popular type of FTTB connection - this is "optics" stretched to your house (but not to your apartment!);
2. low cost of services unlimited connection will cost only a few hundred rubles a month);
3. stable and high-quality connection, with low ping, which is very important for gamers (one of the most stable today);
4. there is practically nothing to buy: a network card is in every modern PC (and companies often provide a Wi-Fi router for free ...).

Minuses:

1. the need to lay a cable in an apartment / house;
2. available only in relatively large cities (moreover, if you have a new or remote area, it may well be that not a single operator has connected your house).

Over coaxial (television) cable (DOCSIS)

This type of connection is not common in our country. Internet connection is carried out via a television cable (KTV), speeds up to 42 Mbit / s are provided (agree that not much, given modern realities).

The principle is approximately the following: a special is connected to the television cable. cable modem - one output goes to the PC (the Internet is distributed), the other to the TV. You can work with the Internet in parallel with watching TV programs (one does not interfere with the other!).

At all, given type connections are more used in bedrooms and remote areas where there is simply no other choice (say, Ethernet). Well, or in those cases when you already use cable TV services and there is no desire (opportunity) to lay another cable into the apartment (for example, it is unreasonably expensive).

Wireless and mobile Internet access (GPRS, EDGE, 3G/4G, WiMax, etc.)

The most advanced and one of the most developing areas. I do not even undertake to single out any of the types of connection separately. Perhaps we should focus on 3G / 4G. "it" is in every modern phone...

In general, now any smartphone is able not only to access the Internet itself, but also to share (distribute) it to neighboring PCs / laptops / other smartphones. In many major cities, 3G / 4G coverage is most common (4G provides speeds up to 100 Mbps and higher (in practice, the speed "dances" in different parts of the city, and it's good if it is 20-30 Mbps)).

To connect a computer to the Internet via a smartphone, it is enough: connect it to a USB port, and activate the modem mode on the smartphone (it is available in every modern device). Also, on a smartphone, via modem mode, you can create a Wi-Fi network and distribute the Internet using it (everyone who connects to it will also get access to the Internet). See screenshots below.

Addition!

You may need an instruction: how to distribute the Internet from Android to a computer or laptop -

I note that now modems (in the form of flash drives) are also popular, which can be connected to any PC / laptop to a USB port. Provide a fairly good quality of communication.

Mob benefits. Internet:

1. there is no need to buy anything in addition (if we do not take into account special modems);
2. the Internet can be distributed very quickly for any device (including even on the road or in nature);
3. a sufficiently large coverage area (can be used in areas where there is nothing else);
4. V Lately more and more unlimited tariffs appear.

Minuses:

1. communication costs several times more than the same leased line;
2. often high ping, which is not suitable for most fans of network games (in general, the quality of communication depends on the area and distance from the tower);
3. not as fast as other connection types.

satellite connection

This is not a very popular type of connection (very expensive), and is used only in remote parts of the country where there is simply no other alternative. Access speed is highly dependent on the equipment that will be provided to you. Of the most important disadvantages of this type of connection, which is worth noting is the presence of a very high ping: at least 250 ms (this is a lot)!

Pros:

1. the possibility of installation in almost any part of the country;
2. independence from terrestrial communication channels.

Minuses:

1. very high ping (250 ms and above) - it is almost impossible to play network games or talk over IP telephony;
2. high cost of equipment and payment for services;
3. the need to coordinate the installation of equipment (not always and not everywhere);
4. bulky and sophisticated equipment(do not install or configure by yourself).

PS

It is possible that all this (what I wrote in this article) will soon make no sense ... This is me about the words of Elon Musk, who promised that in a few years he would cover the Earth with satellites and provide almost all the inhabitants of the planet with free and fast Internet access! Tempting!

However, I personally think that his words were not without advertising and pathos: maybe they will cover the Earth with satellites, but it will be in 15-20 years (minimum) ...

That's all for me. Good luck!

Almost every owner of a personal computer, almost immediately after buying it, thinks about the issue of connecting to the World Wide Web, which makes it possible to communicate with people from all over the world, download and search necessary information, use of various services ( Email, streaming media) and services (web forums, blogs, online stores), and much more. Of course, the question arises before the user, but how to connect to the global network and what methods of this connection exist? If just a few years ago, the majority of network users in Russian Federation, in fact, there was no other choice but to use a modem connection via a telephone line (Dial-Up-connection), but now the situation on the information services market has changed significantly. This material is designed to help you understand among the multiple options for connecting to the network and choose the best one for you.

NETWORK CONNECTION METHODS

At the moment, the most common methods of connecting to the World Wide Web are:

• Ordinary modem connection or the so-called dial-up access (Dial-Up)
• Modem connection via asymmetric digital subscriber line (ADSL)
• Broadband leased line access (Ethernet)
• Access using Mobile WiMAX technology
• Access via Wi-Fi technology
• Mobile GPRS/3G access
• Satellite network connection

They differ from each other by the principle of operation, the speed of sending data, reliability, the difficulty of setting up equipment, and of course, the cost.

CONNECTION SPEED

Separately, it is worth talking about the fundamental characteristic of each connection to the worldwide network - the data transfer rate, which is determined by their number transmitted to the user per unit of time (per 1 second). Typically, the amount of data transferred is defined either in kilobytes/second (KB/s) or kilobits/second (kbps). For ordinary users, the measurement in bytes is more understandable, as it does not contain cumbersome numbers. Remember that 1 byte = 8 bits, while this ratio remains true for values ​​\u200b\u200bwith prefixes: kilo, mega or giga. Knowing how to translate bytes into bits will come in handy when you start studying the tariffs of Internet providers who are very fond of indicating the Internet connection speed in bits, since in this case the figure is more impressive (8 times). Also keep in mind that for channels with a high connection speed, the measurement is already in megabits or megabytes per second.

To make everything clear, let's look at a small real-life example. If the provider promises you a speed of 5 Mbps, which is equivalent to 0.625 Mbps (divide 5 by 8), this means that a 100 Mb file in best case you will be downloading from the network for a little less than three minutes (100 / 0.625 = 160 sec).

The use of the Internet for each user can occur in different ways, for some it is associated with receiving a large amount of Internet traffic, for others it is not. For example, for ordinary web surfing (browsing pages of sites), the speed of an ordinary dial-up connection is sufficient, but given speed will not allow you to comfortably download large files from the network - high-quality music or movies, software distributions and other "heavy" content. To fully utilize the capabilities of the Internet, you will need access with a higher speed.

So, having dealt with the connection methods and the concept of connection speed, let's move on to their description.

dial-up access (DIAL-U.P.)

This is the "oldest" and widely used method of connecting to the global network using a modem and a telephone line. However, in our time, it is being actively replaced by more modern methods of connection and is now used either in rural (remote) areas where there is no possibility of connecting to the network using high-speed lines or by users with a very limited budget.

At this method connection, the user, every time to enter the global network, will have to dial through the modem over the telephone line in order to "get" to the provider's modem pool. Following this, the provider checks the account name (login) and password of the user. In case of successful processing of the entered parameters, the subscriber is assigned a free IP address, with the help of which he gets access to the Internet.

The advantages of such a connection are: ease of setup and installation of equipment (only a modem is needed), low cost of equipment.

There are many more shortcomings in the modem connection. Occupancy of the telephone line at the moment when you are online, low information transfer rate (usually 3-5 kb / s), poor quality of communication and data transfer due to wear and tear of telephone lines and outdated equipment at the PBX. It is clear that at the speed provided by a modem connection, it is impossible to download large files from the Internet - videos, software distributions, etc.

To connect using this method, you will need an internal analog modem if your phone line is good, or an external one if your phone line is poor.

HIGH-SPEED ACCESS WITH ADSL TECHNOLOGY

A much more advanced and modern connection method compared to Dial-up connection. Literally, the abbreviation ADSL (Asymmetric Digital Subscriber Line) can be translated as: “asymmetric digital subscriber line”. This technology allows you to provide high-speed access to the worldwide network via ordinary analog telephone wires (lines) using a special modem. Unfortunately, this connection method has one significant limitation - ADSL equipment (multiplexer) must be installed on the PBX serving you. And if in large cities this is not a problem, then on the periphery for many users such a connection may not be available.

The main advantage of this method is the ease of installation and connection of equipment, as in the case of dial-up access (only a modem is needed), and the maximum throughput such connection reaches 8 Mbps (up to 24 Mbps in case of ADSL 2+). This is quite enough for effective work with various kinds of data and multimedia content. In addition, the technology does not load a regular channel telephone communication, and the subscriber does not need to dial the provider, since the connection is permanent.

It must be said about the possible disadvantages of this method of connection. Not every user can be satisfied with the connection price and the subscription fee charged by the provider for their services. And if in many European countries ADSL is the de facto standard while providing the population with an inexpensive and sufficient fast internet, then in Russian conditions, a lot will depend on the region and the number of competing providers. In the absence of any competition in this area, you may face grossly inflated rates.

There is another negative point in ADSL technology that all fans of peer-to-peer networks that use torrent clients to download information from the network should pay attention to. When using this type of connection, the speed of receiving (downloading) information from the Internet is much higher than its return, which violates the basic principles of file sharing in such networks.

Required equipment:

• ADSL modem
• ADSL splitter (usually included with the modem)

WIDEBAND ACCESS

It is the optimal connection, as it can provide the highest speed of receiving and transmitting information in the global network (up to 100 Mbps). Broadband access makes it possible to use the Internet, its services and services with full efficiency and efficiency.

In this case, the connection is made by an Internet provider, which conducts a dedicated line (usually a twisted pair cable) to the subscriber's computer (apartment) and issues a range of IP addresses for the subscriber to access the Network.

The obvious advantages of this connection method are not only a high speed of information exchange, but also a free telephone, constant interaction with the network, and excellent communication quality.

The only obstacle for many users may be the price of installation and configuration of such a connection, which directly depends on the distance of your computer to the connection point of the provider. Most likely, it will be higher compared to other connection methods. True, it is worth noting that: firstly, this is a one-time payment, and secondly, many providers, in order to attract customers, carry out a free connection.

To connect one computer, the user only needs a network card. Currently, it is built into almost every computer. If you are deploying a home network for multiple wireless-enabled computers, you will need an additional wireless router.

ACCESS THROUGH TECHNOLOGYMOBILEWIMAX

This technology is used to provide wireless broadband Internet access. WiMAX is a long-range system that covers kilometers of space and allows the user to receive both fixed access (similar to the usual xDSL only without wires) and mobile access, allowing you to connect to the network from anywhere within the coverage area. As a rule, fixed access is used to deploy small office and district networks, while mobile access is aimed at the end user.

The first and largest mobile WiMAX network in Russia was deployed by Yota. The maximum data exchange rate in such networks is up to 10 Mbps, which allows you to comfortably download large files, watch videos or participate in online games. The connection to Yota itself is carried out using a special modem (usually made in the form of a USB key fob) in a matter of minutes.

Unfortunately, the main disadvantage of such a connection is its very limited distribution on the territory of the Russian Federation. At the moment, Mobile WiMAX from Yota is available only in eight cities of Russia (Moscow, St. Petersburg, Krasnodar, Sochi, Ufa, Vyborg, Luga and Serpukhov), and even inside them in many areas the signal level leaves much to be desired.

ACCESS THROUGH TECHNOLOGYWI-FI

Unlike WiMAX, Wi-Fi is a system covering much smaller spaces (no more than 150-200 m with one access point) and is usually used by users to access their own local networks, which, by the way, may not be connected to the Internet. This is an excellent solution for simultaneously connecting multiple computers to a network without wires, both at home and in small offices.

The access point itself, which broadcasts the Wi-Fi radio signal, connects to world wide web using a wired connection. Also, Wi-Fi networks are often used in restaurants, cafes, shopping malls, airports and railway stations, through which visitors to these places can access the Internet for free. Thus, we can say that this technology is an auxiliary tool that allows many users to use the capabilities of a single point of broadband Internet connection at once.

MOBILE INTERNET (GPRS/3G).

Due to the very rapid development mobile communications in the Russian Federation, probably, every adult already has mobile phone. And if desired, it can also be used to access the global network. In fact, all providers today offer the service of using a cell phone instead of a traditional modem, creating all sorts of special tariffs for this. In addition, almost all operators now offer independent solutions in the form of specialized GPRS / 3G modems or routers with Wi-Fi support, capable of providing Internet access via mobile networks.

As a rule, this type of connection is the prerogative of users. mobile computers(laptops, netbooks), allowing them to use the Internet anywhere where there is a cellular connection. It is also suitable for poorly accessible areas and places with poorly developed cable networks. For example, using mobile connection can be very useful in the suburban area.

Compact 3G modem in the formUSB key fob

The main advantages of this connection method can be called high mobility and almost universal availability of connection in the areas covered by cellular networks. At favorable conditions, using modern 3G routers, the speed of mobile Internet can reach 7 Mbps, and support for Wi-Fi technology will allow you to organize a connection to the global network for several devices at once.

But as always, there is also a fly in the ointment, which may make it inappropriate to use this type of connection as the main one at home. The speed of such a connection is highly dependent on the mobile operator and becomes acceptable only in 3G networks, the coverage density of which, so far, is not very high in the Russian Federation. Unfortunately, in many cases (lack of 3G networks, poor signal level), the speed of the mobile Internet leaves much to be desired and is slightly superior in its characteristics to dial-up access (Dial-Up). And this, in turn, imposes certain restrictions on its functionality.

We also note that with limit tariffs (imposing restrictions on the amount of information received from the Internet), which allow using the mobile Internet at maximum speeds, the cost of such connection traffic for many users will be quite high. In the increasingly popular unlimited tariffs, as a rule, there is a serious limitation on the connection speed, which can be imposed after exceeding the implicit limit on the amount of downloaded data from their network.

Required equipment:

• Cable for connecting the phone to the computer when using the phone
• GPRS/3G modem or router

SATELLITE INTERNET.

This method makes it possible to permanently connect to the network computers remote from telephone lines at considerable distances ( country cottage area), and will also be useful in hard-to-reach areas with bad reception cellular signal.

Satellite connection is asynchronous (one-way) and synchronous (two-way). The second connection method, due to the high cost of equipment (here the bill goes to tens of thousands of rubles), we will not consider.

The most commonly referred to as satellite Internet is an asynchronous (combined) access method - this is when information comes to the user through a satellite dish, and the traffic request from the user is transmitted by another connection - for example, via GPRS, ADSL or Dial-Up. It should be noted that the main requirement for the request channel is the reliability of the connection.

The data transfer rate with this connection method can range from 256 to 4000 Kbps and strongly depends not only on the provider, but also on the selected tariff plan.

The main advantage of satellite connection to the Internet is the extremely low price of traffic (from 10 kopecks to 1 ruble per 1 megabyte), the ability to organize connections in remote areas, due to independence from land lines and the availability of satellite television.

The disadvantages include: the need for a channel for outgoing traffic - as a rule, a cell phone with GPRS support and a rather high cost of equipment and its installation.

Required equipment:

• Satellite dish with bracket
• DVB card for satellite signal decoding
• Converter

CONCLUSION

So, having considered all the main ways to connect to the global Internet, let's summarize. Undoubtedly, the fastest and highest quality connection to the global network will be wired broadband access. Data exchange through peer-to-peer networks, IP telephony, IP television, local resources of local networks, deployment of own wireless WiFi networks and of course, the full use of all kinds of services or services of the Internet - all this will be available to you when using this high-speed connection. Unfortunately, this type of connection is available only in large cities where fiber optic communication lines are laid.

Good alternative broadband access will serve ADSL technology, which also allows high-speed access to the network (up to 8 Mbps) and quite effectively use all the possibilities of the Internet. True, fans of exchanging files using torrent clients may face serious troubles due to the peculiarities of this technology, and, as a result, the low upload speed. It should also be remembered that the presence of a telephone line is not yet a guarantee that you will be able to use this connection method, since another necessary condition is to place special ADSL equipment on your PBX.

The use of mobile technologies to connect to the network at home is most appropriate in areas with low cable coverage, as well as at highly inflated tariffs for services. wired internet. But remember that comfortable work in the global network is possible only in cellular networks of the third generation 3G. Otherwise, the speed of information exchange will leave much to be desired. And of course, this connection method is most in demand by owners. cell phones, tablets, netbooks and other mobile devices who want to have access to the Internet anywhere in the coverage area of ​​​​cellular networks.

If you plan to connect the Internet in a place with a low level of cable coverage, where there are no fixed telephone lines or local PBXs are not equipped with specialized equipment, and there are no 3G mobile networks, then satellite Internet will be the best solution. Low cost of traffic, acceptable data exchange speed and the ability to watch satellite TV are the main advantages of such a connection among wireless solutions. True, you will have to fork out for the purchase and installation of equipment.

The promising MobileWiMAX technology has an undeniable advantage in the form of high speed and ease of connection to the network. In fact, this is the Internet in your pocket. In a matter of minutes, almost any computer can be connected to the World Wide Web using a miniature modem, made in the form of a USB key fob. Only now the coverage area of ​​​​such networks in Russia is now negligible, and the thick walls of your house can become an insurmountable obstacle to the passage of a weak signal. So before giving preference to this method of connection, check out the coverage area in your region and in general its availability.

Connection using dial-up access (Dial-Up) today can be considered completely outdated, and its use can only be presented as a budget option on telephone lines that do not support ADSL technology.

In conclusion, let's say a few words about prices. In the big cities of Russia, due to the growing rivalry of Internet providers, and mass development local networks, access to the World Wide Web is becoming less and less expensive. From the point of view of choosing a tariff plan, unlimited Internet access with a fixed monthly subscription fee can be considered the most profitable. For example, in Moscow for 400 - 500 rubles a month you can connect to the network at a speed of 8 - 10 Mbps, the cost of unlimited mobile Internet will cost you 390 rubles, and connecting to MobileWiMAX at maximum speed - 1400 rubles. But in provinces or small towns, prices for services providing access to the global network can be greatly inflated due to weak competition among providers or its complete absence. In such cases, pay attention to mobile connection tariffs or satellite Internet, in which pricing does not depend on the region.

That's all. Successful connection to the global network!
