Types of Internet access. Reliable Operation Rule

In our information age, it is difficult to find a person who has not used the Internet at least once in his life. The World Wide Web has embraced both large cities and the most remote settlements of our country. Previously, it was possible to connect to the network only using a regular landline telephone using a Dial-Up modem. Now the situation has changed dramatically. Let's look at what methods of connecting to the Internet exist, and talk in detail about the technical aspects of connecting to the World Wide Web.

Methods of connecting to the Internet

Having become the owner of a home computer, within a few days the user begins to think about the possibility of connecting to the World Wide Web. There are a lot of ways to do this. Let's look at the most common ones:

Below are the most popular and accessible methods of connecting to the Internet.

Available to everyone: Internet via ADSL modem

Connecting to the Internet via a Dial-Up modem has long been replaced by ADSL technology. Let's compare these two, until recently the most popular, connection types:

Mobility first: mobile phone and wireless modem

Laptop owners choose a mobile phone or wireless modem to connect to the World Wide Web:

1. GPRS. Packet data transfer is carried out using GSM communication standard. Technology Features:

• Speed ​​up to 171.2 Kbps.
• Payment for traffic (received and sent volume) is carried out for each megabyte used.
• Ability to use the Internet using both a laptop and a smartphone.

1. 3 G and 4G. High-speed network access technologies used in modern wireless modems:

• Speed: 3G up to 3.6 Mbit/s, 4G starts from 346 Mbit/s.
• The protection of data transmission interruptions carried out at high speed (railway transport, cars), which was the “Achilles heel” of 1G, has been worked out.
• The prospect is to achieve transmission speeds of up to 1Gb/s in the coming years.

Massive use and popularity: dedicated channel

Network access when using a dedicated channel, is by far the most widespread and popular. Let us name the main features of this method:

Ways to search for information on the Internet

Hundreds of gigabytes are added to the Internet every day. new information. To find the necessary data, there are search engines like . They are the ones who dig up hundreds of millions of pages around the clock, which in turn are located on tens of thousands of servers, and organize the information thematically. All major “search engines” allow you to search for data using the following criteria:

• Keywords. Enter in the search field keywords, characterizing what is being sought.
• Photo. The photo is loaded in a special field, and the search engine returns the addresses of sites with similar images.
• Video. While on the video tab, the search engine will return media files with the entered data in their name.

In the search parameters you can specify the expected date of publication the required material online that will significantly improve the quality of the result obtained.

Now, knowing what methods of connecting to the Internet exist, you can weigh everything “ behind" And " against” and start looking for a provider of this service - a provider. In addition to technical characteristics, such as information transfer speed and connection stability, it is important to choose a solution that will be feasible from an economic point of view. Fortunately, in large cities, due to competition between Internet providers, the price for using the service is gradually becoming cheaper.

We are confident that the tips provided in our review will will help you make the right choice.

Video about connection methods and the Internet

In this video, IT technology engineer Artem Babakov will tell you what methods of connecting to the World Wide Web there can be in rural areas:

Almost every owner of a personal computer, almost immediately after purchasing 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 for the necessary information, and use all kinds of services ( Email, streaming media) and services (web forums, blogs, online stores), and much more. Of course, the user is faced with the question of how to connect to global network and what methods of this connection exist? If just a few years ago, the majority of network users Russian Federation, in essence, there was no other choice but to use a modem connection via a telephone line (Dial-Up connection), now the situation in 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 most optimal one for you.

NETWORK CONNECTION METHODS

On this moment The most common methods of connecting to the World Wide Web are:

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

They differ in the principle of operation, the speed of sending data, reliability, the difficulty of setting up the equipment, and, of course, cost.

CONNECTION SPEED

It is worth talking separately about the fundamental characteristic of each connection to the World Wide Web - the data transfer speed, which is determined by the amount transmitted to the user per unit of time (per 1 second). Typically, the amount of data transferred is determined either in kilobytes/second (KB/s) or kilobits/second (kbps). For ordinary users, the measurement in bytes is more understandable, since it does not contain cumbersome numbers. Remember that 1 byte = 8 bits, and this ratio remains true for quantities with prefixes: kilo, mega or giga. Knowing how to convert bytes to bits will come in handy when you start studying the tariffs of Internet providers who really like to indicate the Internet connection speed in bits, since in this case the figure turns out to be more impressive (8 times). Also keep in mind that for channels with high connection speeds, the measurement is already in megabits or megabytes per second.

To make everything completely clear, let's look at a small real example. If the provider promises you a speed of 5 Mbit/s, which is equivalent to 0.625 MB/sec (divide 5 by 8), this means that at best you will download a 100 MB file from the network in less than three minutes (100 / 0.625 = 160 sec).

Each user's use of the Internet can be different; for some it involves receiving a large amount of Internet traffic, for others it does not. For example, for ordinary web surfing (viewing website pages), the speed of an ordinary modem connection is sufficient, but this speed will not allow you to comfortably download large files from the network - high-quality music or films, software distributions and other “heavy” content. To take full advantage of the Internet, you will need higher speed access.

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

DIAL ACCESS (DIAL-UP)

This is the “oldest” and widely used method of connecting to the global network using a modem and telephone line. However, in our time, it is being actively replaced by more modern connection methods 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 telephone line using a modem in order to “get” to the provider’s modem pool. Following this, the provider checks the user's login name and password. If the entered parameters are successfully processed, the subscriber is assigned a free IP address, through which he gains access to the Internet.

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

There are many more disadvantages to a modem connection. Busy telephone line at the moment when you are on the network, low speed of information transfer (usually 3-5 kb/s), low quality of communication and data transfer due to wear and tear of telephone lines and outdated equipment on the PBX. It is clear that with 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 in case of a high-quality telephone line, or an external one if your telephone line leaves much to be desired.

HIGH SPEED ACCESS WITH ADSL TECHNOLOGY

Much more advanced and modern way connection 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 worldwide network via ordinary analog telephone wires (lines) using a special modem. Unfortunately, this connection method has one significant limitation - the PBX serving you must have ADSL equipment (multiplexer) installed. And if in large cities this is not a problem, then in the periphery many users may not have access to such a connection.

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

It must also be said about the possible disadvantages of this connection method. Not every user can be satisfied with the price of connection and the subscription fee charged by the provider for its services. And if in many European countries ADSL is the de facto standard for providing the population with inexpensive and fairly fast Internet, but 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 be faced with greatly inflated rates.

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

Required equipment:

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

BROADBAND ACCESS

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

In this case, the connection is made by the Internet provider, which runs 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 Internet.

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

The only obstacle for many users may be the cost of installing and setting up 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. However, it is worth noting that: firstly, this is a one-time payment, and secondly, many providers, in order to attract customers, provide free connections.

To connect one computer, the user only needs a network card. Nowadays it is built into almost any computer. In case of deployment 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 regional networks, but 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 speed in such networks is up to 10 Mbit/s, which allows you to comfortably download files big size, watch videos or participate in on-line games. The connection to Yota itself is carried out using a special modem (usually in the form of a USB key fob) in a matter of minutes.

Unfortunately, the most important disadvantage of such a connection is its very limited distribution in 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 within them in many areas the signal level leaves much to be desired.

ACCESS THROUGH TECHNOLOGYWI-FI

Unlike WiMAX, Wi-Fi is a system that covers 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 several computers to a network wirelessly, both at home and in a small office.

The access point itself, broadcasting the Wi-Fi radio signal, connects to the World Wide Web using a wired connection. Wi-Fi networks are also 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 simultaneously use the capabilities of one broadband Internet connection point.

MOBILE INTERNET (GPRS/3G).

Due to the very rapid development of mobile communications in the Russian Federation, probably every adult already has a mobile phone. And if desired, it can also be used to access the global network. In fact, all providers these days 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 that can provide 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 there is cellular. It is also suitable for poorly accessible areas and places with poorly developed cable networks. For example, using a mobile connection can be very useful in a suburban area.

Compact 3G modem in the formUSB key fob

The main advantages of this connection method include high mobility and almost universal availability of connections in areas covered by cellular networks. Under favorable conditions, using modern 3G routers, the speed mobile internet can reach 7 Mbit/s, 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 a fly in the ointment, which may make it impractical to use this type of connection as the main one at home. The speed of such a connection greatly depends on the mobile operator and becomes acceptable only in 3G networks, the coverage density of which is not yet very high in the Russian Federation. Unfortunately, in many cases (lack of 3G networks, poor signal level), the speed of mobile Internet leaves much to be desired and is slightly superior in its characteristics to dial-up access. And this, in turn, imposes certain restrictions on its functionality.

We also note that with limited tariffs (imposing restrictions on the amount of information received from the Internet), allowing the use of mobile Internet at maximum speeds, the cost of traffic for such a connection will be quite high for many users. 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 unofficially established limit on the amount of downloaded data from their network.

Required equipment:

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

SATELLITE INTERNET.

This method makes it possible to permanently connect computers to the network that are located considerable distances away from telephone lines (dacha area), and will also be useful in hard-to-reach areas with poor cellular signal reception.

Satellite connections can be asynchronous (one-way) or synchronous (two-way). The second connection method, due to the high cost of the equipment (here the account it's already underway for tens of thousands of rubles) we will not consider.

Most often, satellite Internet is called an asynchronous (combined) access method - this is when information arrives to the user via a satellite dish, and the request for traffic 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 connection reliability.

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

The main advantage of a 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, thanks to independence from land lines and the availability of satellite television.

The disadvantages include: the need to have a channel for outgoing traffic - usually a cell phone with GPRS support and the fairly high cost of equipment and its installation.

Required equipment:

• Satellite dish with bracket
• DVB card for decoding satellite signal
• 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 your own wireless Wi-Fi networks and of course, full use of all kinds of Internet services - all this will be available to you when using this high-speed connection. Unfortunately, this type of connection is only available in large cities where fiber optic communication lines are installed.

A good alternative to broadband access is ADSL technology, which also allows high-speed network access (up to 8 Mbit/s) and quite efficient use of all the capabilities of the Internet. True, those who like to exchange files using torrent clients may encounter serious troubles due to the peculiarities of this technology, and as a result, the low upload speed. You should also remember that the presence of a telephone line does not yet guarantee that you will be able to use this connection method, since another a necessary condition is the placement of special ADSL equipment on your PBX.

The use of mobile technologies to connect to the network at home is most advisable in areas with low cable coverage, as well as in highly inflated tariffs for wired Internet services. But remember that comfortable work on the global network is only possible in third-generation 3G cellular networks. 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 others mobile devices who want to have access to the Internet anywhere in the cellular network coverage area.

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

The promising MobileWiMAX technology has the undoubted advantage of high speed and ease of connecting to the network. Essentially, it's 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 designed in the form of a USB key fob. Only the coverage area of ​​such networks in Russia is now negligible, and the thick walls of your house can become an insurmountable obstacle to passing weak signal. So before choosing this connection method, check out the coverage area in your region and its availability in general.

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

In conclusion, let's say a few words about prices. IN big cities In Russia, due to the growing competition between Internet providers and the massive development of 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 per month you can connect to the network at a speed of 8 - 10 Mbit/s, the cost of unlimited mobile Internet will cost you 390 rubles, and connecting to MobileWiMAX at maximum speed- 1400 rub. But in the provinces or small populated areas 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. Good luck connecting to the global network!

To access the Internet, there are several ways to connect it, which differ from each other, in fact, in the connection technology itself, tariffs for use, as well as technical characteristics that determine the speed of information transfer, the stability of the connection itself, response time, and other subtleties . As you can see, the quality of the Internet depends not only on the hardware capabilities of the computer or mobile device used, as some believe. The providers of this service - special organizations, the so-called providers - are responsible for the quality of the Internet connection itself.

But, about everything in more detail - we will consider below the most common methods of connecting to the Internet, their features, advantages and disadvantages.

1. Satellite Internet

2. Mobile Internet

The name itself speaks for itself. This is the Internet, which you can use wherever you are in the coverage area of ​​your provider (mobile operator). There are two connection options: via a mobile phone or via a special modem. The latter can be connected to a smartphone, tablet or laptop via USB ports (miniUSB) as a separate small device. Manufacturers often equip some models of computer and mobile equipment with such a modem.

Almost all modern Cell phones have Internet access. Somewhat outdated models are connected using slow and at the same time expensive GPRS technology. And for more modern mobile devices - smartphones and tablets - mobile operators offer high-speed connection technologies that can provide access to the Internet wherever this operator has coverage. These are technologies such as: CDMA, WiMAX, LTE, UMTS. If the gadget is not equipped with a built-in modem that can support these technologies, almost all mobile operators can offer their own branded plug-in modem.

The data transfer speeds of these technologies can vary greatly depending on the user's location. However, special Internet signal amplifiers are now being produced that can increase this speed significantly.

3. Telephone connection (dialup)

This is by far one of the most common methods of connecting to the Internet in Russia, but far from the best. Used if a landline telephone is installed in the apartment. By connecting a computer or laptop via a wired modem to a telephone line, you gain access to the Internet. The phone will naturally be busy at this time, and it will not be possible to use it until the end of the Internet session. And this is not the only drawback of a telephone connection - for example, this method of Internet connection is one of the most expensive, and perhaps the slowest.

4. Wi-Fi

Wi-Fi (Wireless Fidelity) is one of the modern species wireless communication. Almost all smartphones, tablets and laptops have a built-in special module that allows you to access the Internet while within range Wi-Fi points access (usually range of about 100 m). The Wi-Fi module can also be purchased separately and connected to a PC either as a separate built-in card or as an external device connected via USB.

So far, this type of connection is not in widespread demand among Russian users, despite the fact that many, by connecting an Internet network cable to a router, could freely move around the house with a laptop, tablet or smartphone and use the Internet. In Russia, Wi-Fi is more of an additional feature for the service business. Users can (as a rule, completely free) have access to the Internet in various public places - at airports, train stations, cafes, hotels, gas stations, etc.

By her own Wi-Fi technology quite fast, but due to the fact that access points are usually overloaded, the final speed sometimes leaves much to be desired.

5. ADSL

ADSL is a special type of Internet connection via a telephone line, and access to the Internet does not interfere with the operation of the phone. The quality of such a connection is an order of magnitude higher than with a regular telephone connection. It has a high information transfer speed and excellent stability.

6. Direct connection

This is the best way to connect to the Internet today. The user's computer is connected to the provider using a regular network cable. The advantages of this connection are its high speed, stability, reliability, and low cost. But this method, unfortunately, is available only in large populated areas - where the cable lines of local providers run.

The Internet has long become not only the norm, but even a necessity in our lives. A lot of things depend on the use of the World Wide Web. But it is impossible to connect to it by simply plugging the cord into an outlet. Let's look at what types of Internet connections exist.

Over time, outdated Internet technologies are replaced by more advanced ones

Cable connection

Twisted pair and optical cable

This is the most popular connection type. A cable is installed in your apartment or office through which the Internet signal is received. There are two connection options: twisted pair and optical cable.

In the first case, a high-bandwidth fiber optic cable is installed from the service provider to the house or distribution box, and a twisted pair cable is installed into the apartment itself, which is a copper wire with a specially crimped end that is plugged into a computer or router. The connection speed in this case most often does not exceed 100 Mbit/s.

In the second case, an optical cable is installed in the home and connected to a distribution device. Among its advantages are much higher speeds, up to 1 Gbit/sec. Using this cable you can simultaneously receive Internet, telephone and television services - that is, one cable instead of three. Cable connection has two options for organizing a network: local and virtual.

The local network

The essence local network is that the provider assigns you a separate IP address. All computers, by and large, form a large network that has access to the Internet through a provider. There is access with dynamic and static IP.

Dynamic IP

This is the easiest type of communication for you. All settings for each connection are assigned by the provider, and you do not need to configure anything additional. You simply plug the cable into your computer or router and start using the Internet.

Static IP

With this type, the user needs to enter into the settings of the network card or router the parameters that are issued by the provider and which are unchanged during each communication session. This is quite convenient for online services that ask you for a permanent IP address. You can find out the type of connection in the provider’s technical support, on the service provider’s website, or in the contract. When using a router, most models can detect the connection type automatically.

Virtual VPN

VPN stands for “virtual private network.” This technology encrypts data exchange between the subscriber's computer and the provider's server, significantly increasing security.

The most popular type of VPN connection. To use you only need to know your login and password. The Windows operating system treats this connection as a broadband dialing connection.

L2TP/PPTP

Less popular types VPN connections. In addition to your login and password, you need to find out the server address provided by your telecom operator. The difference between them is only in the encryption method, which is selected in the additional connection settings. The most famous provider working with this standard is Beeline.

Combined connection

Combines several types of connections for accessing the Internet and provider resources. VPN is used as the main connection type, dynamic or static IP - as an additional one. The difference between them is the manual entry of a local address or its automatic determination. This connection is considered the most complex and is therefore rarely used. You can find out the parameters from the technical support of a specific service provider.

Phone line

Despite the fact that in Lately cable connection dominates, in many areas it is not economically feasible to run a separate Internet line. In this case, it helps to have a telephone line; you can only connect to the Internet through it. There are two types of connection: ADSL and Dial-Up.

ADSL

Modern standards provide access to the Internet at speeds of several tens of megabits, which is quite enough for most tasks. The bottom line is that with the help of a splitter the signal is divided into different frequencies: low - for voice communications, high - for the Internet. Accordingly, you can make calls and use the Internet at the same time.

A modem is used to organize communication. The connection diagram is quite simple: the telephone cable, which is brought into the room, is connected to the splitter, and the home telephone and ADSL modem are connected to it in the corresponding connectors.

Dial-Up

This type of connection has come to us since the nineties of the last century. It is very outdated, since when used, the telephone line remains busy, and the average speed is about 56 kilobits. By today's standards this is very little. However, in some areas this type of connection is sometimes used.

It works as follows: the modem is connected to the telephone line and to the computer, and the modem pool number is added to its settings. The modem calls this number, and after the connection is established, the subscription gives you access to the Internet.

TV cable DOCSIS

This type of connection provides Internet via television cable. Undoubtedly, it is much more convenient to pay for the Internet and TV to one company. The cable is inserted into an apartment or house, and with the help of a splitter the signal is distributed to television and Internet. The Internet signal is sent to a cable modem connected to a PC or router.

Modern standards allow Internet speeds of up to 300 Mbit/sec. Despite the relatively low popularity of the technology, telecommunications service provider AKADO connects subscribers in Moscow, St. Petersburg and Yekaterinburg using it.

Mobile Internet

The development of 3G and 4G standards allows you to use the Internet at a speed comparable to a home connection. In many Russian cities, the 4G standard is available with speeds of up to more than 100 megabits. Where it is not available, 3G operates at speeds of up to 40 megabits.

Recently, unlimited tariffs have been offered, albeit rather conditional ones. No wires are needed and you can connect relatively cheaply anywhere where coverage is available. You can use a USB modem, mobile router or smartphone/tablet as a modem. Built-in software can also determine network parameters.

Satellite Internet

The most expensive, but at the same time the most ubiquitous. Allows you to access the Internet even far from communications, even in the middle of the taiga. The only condition is visibility of the satellite.

Everyone is familiar with satellite television. Antenna dishes can be seen in almost every home and in huge quantities. The same dish is used to access the Internet. There is one-way and two-way satellite Internet.

With one-way access, outgoing requests are transmitted over a terrestrial communication channel, for example, through mobile network, and the incoming data comes from the satellite. With two-way access, all exchange occurs via satellite channel. To do this you will need an antenna with a transmitting head.

Access speed reaches several tens of megabits. The main disadvantage is the huge price for a set of equipment and rather high tariffs.

WiMax and Wi-Fi

Almost everyone is familiar with Wi-Fi; almost everyone has a router at home, and many public places have free access points. WiMax allows you to cover those areas where it is difficult to provide a cable connection in every home. This is applicable in the private sector or cottage communities. To provide coverage, base stations are used to provide coverage within a radius of several kilometers.

To connect, you need to have a special receiver, and when moving away from the station, an amplifying antenna. The technology is not widely used, since it still requires a cable connection to the village. It is much more expedient to use the mobile Internet.

Conclusion

We have listed all possible types of Internet connection. If you live in a city, most likely your provider will connect you via cable. This is the cheapest type of connection in multi-storey buildings. Hardware setup will vary depending on various types connection, you can find out more about this issue in our article How to connect the Internet on a laptop. In addition, never hesitate to contact the service provider's technical support to find out your network access parameters.
