Tele2 LTE frequency. Here, the actions are similar to that overgoing an example, the definition of the range is also displaced by the passage of frequencies. G frequency "other operators"

The article will be useful to those who choose an antenna and equipment for amplifying the mobile 3G and 4G Internet signal, or a repeater to enhance cellular communication.

3G / 4G signal frequency is the initial parameter in the choice of antenna. For example, you can not know the location basic stations On the ground - just catch the signal, and determine the direction by twisting the antenna. But if you do not know the frequency, the signal can not be caught at all.

Important! All testing is recommended to perform at the point of the planned installation of the antenna (with a laptop + modem, ideally on the roof), because In the indoor modem may not catch the signal in the range of 2600 MHz (4G), and for the street antenna it is the most efficient!
Due to the fact that the methods for determining the frequency of GSM / 3G / 4G / 4G + differ, we will pick them separately.

1. Mobile method:

1. Androyd:
Attention! Disable Wi-Fi!
To test frequency, the built-in NetMonitor (network monitor) technical menu is used, which in each model of the smartphone is called by a personal code. List of Android phones and codes like * # 4636 # * # * # * # * # * You can find

For Samsung:Disable Wi-FiAnd select 3G or 4G LTE mode. In the input field telephone number Dial the combination: * # 0011 #, after which telephone will go in service mode With a report on the BS signal to which you are connected.

3G parameter values:

uARFCN. (maybe referred to as RX.): Channel number determining frequency. If value from 10562-10838, then you have 3G / UMTS 2100 MHz.If 2937-3088, then it is 3G / UMTS 900 MHz. In our case uARFCN. = 10687 , therefore, the frequency 3G \u003d 2100.
ECIO (EC / IO or EC / NO): The ratio of the signal level to noise level in (the greater the indicator, the better). The lower the load (the network is free), the closer the ECIO indicator tends to 0. With the increase in the number of subscribers, the bandwidth decreases - the ratio deteriorates up to -12 ..- 14 dB, after which 3G-\u003e 2G switching can occur according to the settings. You may need to choose a direction on a closer tower. For 4G this parameter is indicated as Cinr. .
RSCP: REFERENCE SIGNAL RECEED POWER) The power of the received signal that your device receives when connecting to the BS. -70 Good, -100 bad.

4G LTE values:

Band: The frequency on which the 4G network is running. All of them 3. In our case Band: 7.this is a frequency 2600 MHz , if a Band: 3. that 1800 MHz, I. Band: 20. - Frequency 800 MHz. (Full list frequency bands.)
RSSI:Basic signal power value at values RSRP.\u003d -120 DBM and below LTE connection can be unstable or missing at all.
CINR: The ratio of the level of the useful signal to essential noise. Everything is simple here: the higher this value, the quality of the signal is better. If a Sinr. Below 0, the connection speed will be low, as this means that in the received noise signal more than utility, which increases the likelihood of loss of connections.

1.1 Additional Applications for ADNroid:

Here, no doubt, it is worth noting the Cellmapper application capable of transferring and displaying the value of the operating frequency, information about the tower, about neighbors, display the tower on the map ( an option should be included "Calculate GSM / UMTS / LTE frequencies") As we have already written, the frequency is displayed in value. Band.The signal level is listed in the field. Reference Signal Received Power (RSRP). To work with the application, you must go through free registration on the site.

1.2 Displaying the signal level in standard USB modem applications:

Information about the signal level is made virtually any 3G / 4G LTE modem, it is enough to study the menu.

2. Testing using a USB modem (most reliable):

However , most efficient and inexpensive and reliable way to establish the carrier frequency of the Internet signal remains a computer + modem having an HILINK interface orStick. . Below are the test methodmDMA program using firmwareStick. Which is usually on purchased locked modems of Russian telecom operators.

2.1 Working with the MDMA program:

(Communication parameter display window)

Important! Before starting the programMDMA (Mobile Data Monitoring Aplication) It is necessary to close all the "native" program of the USB modem !!!

After starting the program displays the signal level, the essential noise, and the parameters of the base station. Here, our goal is to determine at what frequency 3G & 4G LTE operator works, By their busting. Press the button"Band Config" we will call the window in which we will do not complicated:

We change the parameter "Automatic" on "Custom"
3G put a tick on to start on UMTS 2100. Click "OK" and follow the main window for the power and register in the network. If the name of the operator appears in the field, and the checkbox appeared next to the "registered", then your operator works at the frequency UMTS 2100.. If registration does not proceed, we rough on the leading step, remove a tick with UMTS 2100. And install on UMTS 900.
If when you select a parameter (for example, UMTS 900), the program issued an error, which means your modem does not know how to work in this standard.
Online 4G LTE Sequence and logicaction similar 3G, for eliminating the fact that all of them are held in the right area (LTE Bands).

2.2 Analysis using a Universal Modem with Hilink Interface:

Here, the actions are similar to that overgoing an example, the definition of the range is also displaced by the passage of frequencies.

Go to Settings -\u003e Network Settings, Next, select the standard (LTE, UMTS or other), set the "manually" mode and begin to mark the tick range by checking the RSSI signal power on the parameter page.

The range of range in 3G networks:

Page with the display of signal parameters

It should be noted that there are cases when the operator broadcasts the Internet immediately intwo bands at the same time. For example, in the city of Chekhov M.O. Tele2 in 4G works parallel to 800 and 2600 MHz. The power of RSSI differs, and the main frequency remains 800 MHz. If you want to provide a greater speed, and for reception to use both frequencies, you should use a multi-standard antenna supporting work on LTE technology - a simultaneously in 2 bands.

Technologies are developing quickly. Not long ago appeared wireless connection 3G Standard, however, a wireless connection of a completely new generation is already becoming replaced by certain steps - 4G. In Russia, only a few companies operate in the 4G market, one of them is Tele2.

What is 4G from "Tele2"

This is the type of communication of the new generation. It is better, more affordable, faster and more comfortable. mobile Internet.

Difference from 3G.

3G combines Internet access at high speed and radio communication. In Russia, he first appeared in 2002. Maximum data transfer rate:

If the device does not move - 2048 kbps.
If the vehicle movement speed is up to 3 km / h - 348 kbps.
If the device moves at speeds more than 120 km / h - 144 kbps.

Regarding 4G, it is able to provide Internet access at high speed and significantly improved voice quality. This generation network began to appear since 2010. Speed \u200b\u200bis significantly higher:

For mobile devices - 100 Mbps
For fixed - 1 Gbit / s.

A new type of communication is based on batch data transfer and a special technology that ensures the transmission of voice signals over the Internet - VoiceOver IP.

The frequency list on which it works in the Russian Federation:

b3 (1805-1880 MHz);
b7 (2620-2690 MHz);
b20 (791-821MHz);
b31 (frequency 450mgz);
b38 (2570-2620 MHz).

Coating map

Now LTE is available in several regions of Russia: Moscow, St. Petersburg, Moscow, Leningrad, Voronezh, Kemerovo, Oryol, Rostov, Tambov, Tula and Ulyanovsk regions, in the Chuvash Republic, Komi Republics, Mordovia, Khakassia and Karelia, Krasnodar Territory and Adygea, Khanty-Mansiysk and Yamalo-Nenets Autonomous Districts, and this is not the entire list.

How to connect 4g on a PC or laptop

There are USB modems with support for 4G and mobile routers. The approximate price starts from 2300 rubles. Setting can take from five minutes to half an hour. The modem needs to be connected to a computer or laptop, insert a disk with drivers, wait for their installation. With a router easier, you need to buy a tariff plan, insert Sims into the device and turn it on.

How to check the ability to connect mobile

Want to know if the smartphone is supported by the fourth generation communication type? There are several ways.

Instruction

A document is applied to any device where characteristics are indicated. There you can find 4G or LTE record, which means that the device supports this type of communication.

Consultant in the store

When buying a new phone, ask the seller, is supported by this model New connection type.

Whether in the search bar of the browser model of your device and find its characteristics. Among them will be indicated which types of communication it supports.

It is worth noting that at the moment even budget models support LTE.

Optimal Telight Tariffs for 4G

Now consider the very favorable tariffs From tele2 to use a new type of communication.

Internet for devices

This is the main and only tariff suitable for this purpose. The month of use is 299 rubles for 7 gigabytes. A minute of call will cost 1.80 rubles. SMS on the numbers of Russia operators - 2.50 rubles minute. The tariff can be used if the device supports this type Communication. The fixed subscription fee is not provided, but will be filmed 3 rubles daily. The tariff is great for all types of devices.

You can purchase a SIM card online and pick it up in the nearest office. Or order it in the office of the operator.

Suitcase Internet

Questions of subscribers

Is it possible to connect 4G to "Tele2 Kazakhstan"

Yes, by visiting the site internet.tele2.kz or by calling free short number 800.

Does the use of 4G affect the flow of traffic?

Yes, and this noticed many users. All because the speed has become higher and, accordingly, traffic spent faster. For an analogy, you can imagine a tap with water, if you open it stronger, more water will be consumed, here too.

LTE Reviews on Tele2

Ivan, Moscow:

I use 4G Internet from tele2 through the modem for about a month. Chose a tariff 7 gigabytes for 300 rubles. The quality of communication pleases, everything is loaded very quickly, you can easily watch the video in high quality.

Igor, St. Petersburg:

I bought a modem and 4G package from the tele2. Previously used Bilain, but I can confidently say that Tele2 surpasses him in quality. Everything loads almost instantly, games quickly download, 3 gigabytes are loaded for about 20 minutes. I use the "Internet Suitcase" package, which provides a package of 60 GB and I calmly grab them for a month. By the way, the price of tele2 is acceptable.

Sasha, Rostov:

By enjoyed for a long time LTE internet service from Tele2 I want to say that this network 4 generations are really something. The speed on which the data is transmitted cannot but rejoice, but the quality of various services, such as TV or video call at times exceeds precursors. Of course, I noticed the people who are not satisfied with this connection, they are not enough, however, I practically do not find in her minuses.

All about tele2 4G (LTE)

Fourth-generation cellular networks that provide high-speed Internet access are drawn by all Russian operators. Someone has a coverage area a little worse, someone is a little better, and someone is represented in a limited number of regions - a lot of differences. The base stations of the fourth generation are also in the telephone discounter operator. Today 4G from tele2 is in many regions, including in small towns. Let's talk about this in more detail.

Technology and coverage area

LTE from Tele2 allows you to feel all the charms of high-speed mobile Internet - it is quick downloading files, viewing video in good quality, small ping and available tariffs. The high coverage of the fourth-generation networks allows you to count on high-quality communication in many settlements of Russia. Their work is carried out in the following frequency bands - Band 7, Band 20 and Band 31.

To work in 4G networks from tele2, you can use any equipment - these are smartphones, tablet PCs, modems and routers. The main thing is that the technique can work in the above frequency bands. If this is not the case, then she simply will not be able to register in the right network. This often occurs with the equipment, which was created to work in other countries where other frequency ranges are used.

But it is not necessary to be afraid of buying equipment - all the devices officially imported to Russia will be able to work in any domestic fourth-generation networks, including 4G from tele2. The main thing is to buy them in official salons, and not through Chinese or any other online stores.

Let's see what we can use 4G networks from the tele2:

Any officially imported smartphones and tablets in Russia;
Tele2 modems and universal modems with the support of the desired ranges;
Any mobile and stationary routers with 4G.

Thus, the range of equipment is not limited, which is already a big plus.

The branded equipment is presented with 4G-modems of tele2, sold complete with a SIM card. They can provide the speed of receiving data to 100 Mbps and the rate of data of data up to 50 Mbps. In fact, the actual speed will be lower, which is associated with the workload of base stations and a large number of subscribers.

Remember that all maximum indicators in specifications Were revealed in laboratory conditions - in practice they are much worse.

In addition to the modem, a compact mobile routers are offered to work in 4G networks from Tele2. Being equipped with batteries, they can work in offline mode. The kit comes with a SIM card. Up to 10 devices can be connected to this router. - These are tablets, smartphones, smart televisions and much more. Built-in battery capacity is 2000 mAh, which provides autonomous work For 5-6 hours (depending on the load).

4G coating from tele2 is present only in the territories settlements - You can get acquainted with the coverage area on the official website of the operator, or right on our website.

Here you will see the built map for the second, third and fourth generation networks - for greater convenience, they are marked with different colors. The widespread coverage is second-generation networks. For them are 3G networks and areas coated with 4G networks.

The map of the 4G coating zone from tele2 is formed by computer simulation method and does not take into account the specifics of the propagation of radio waves and other factors affecting the signal strength and the speed of the Internet at a particular point.

Tariffs and options for 4G Internet from tele2

High-speed Internet is needed not only on the computer, but also on the phone. Therefore, first we will talk about Tel Parifers - in principle, they can be used almost on any devices. These are these tariffs:

"My Tele2" - unlimited challenges on tele2 throughout the country, 5 GB of traffic and unlimited traffic for social networks and messengers. An interesting offer for any metropolitan subscriber. True, it is more aimed at voice communication within the network and messaging in messengers and social networks;
"My conversation" - the tariff includes 2 GB of traffic, 200 minutes of any local challenges, unlimited on tele2 and 50 local SMS for 199 rubles / month. Not bad solution for economical subscribers;
"My Online" - the tariff plan includes 12 GB of traffic, 500 minutes on any Russian phones, unlimited inside the network, 50 SMS in Russia and unlimited traffic for social networks and messengers. The subscription fee is 399 rubles / month;
"My online +" - 30 GB of main traffic, 1500 minutes in Russia, 50 SMS for local rooms, intranet unlimited, unlimited traffic for social networks and messengers for 799 rubles / month.

Select the most appropriate offer from the list and enjoy high-speed Internet in 4G networks from tele2.

When exhausting a dedicated path package is provided. additional Internet Packages Volume of 500 MB of 50 rubles / package. After that, access to the network is suspended.

For work in routers, modems and tablets, a special "Internet for devices" was created. The subscription fee here is 299 rubles / month, which includes 7 GB of the Internet. If this is too small, additional options are connected to the tariff:

"20 GB" with night unlimited - for 699 rubles. / Month. Option is optimal for modems and routers;
"50 GB" with night unlimited - subscribers are provided with 50 GB of traffic with a subscription fee of 999 rubles / month. A good solution for serious users who enjoy Internet on an ongoing basis.

After the exhaustion of the granted traffic, access to the network is suspended. Use to restore access additional packages traffic.

Frequency of tele2 in Russia

To implement wireless mobile telephony and data transfer, cellular operators use radio frequencies that range from 250 MHz to 3 GHz. Considering that these channels are used for other communications, cell phones were allocated four GSM range: 850/900/1800/1900 MHz. In Russia, two ranges (Band) are relevant: 900 and 1800.

The first allows you to cover large areas of service, and the second adapts the service in the territories of small high density Subscribers. The phones themselves can be like two, so three and 4 bands are quite relevant when traveling around the world. In the TV2 GSM, by agreement with other cellular telecom operators, only the range of 1800 MHz is used, the disadvantages of which are compensated by the construction of a larger number of taps for signal transmission. In Moscow, there was no agreement on the GSM standard today.

In this regard, in the capital Tele2 is available, only for subscribers whose telecommunication devices support new generation networks: 3G and 4G.

Optimization of selection and configuration of devices designed to suppress the signal.
Optimize Mobile Phone Settings when accessing engineering menu Telecommunications equipment.
Expanding the presentation and improved understanding of the entity of receiving and transmitting the signal to subscribers / from subscribers of cellular networks.

In GSM standard

Naturally, the reception frequency is presented in a generalized standardized format 900 and 1800. In fact, they differ on average: 889 - 999 and 1710 - 1899, respectively, with minor fluctuations in one direction or another. Between operators are divided by frequency data to avoid difficulties in signal transmission and subsequent tariffing of the services provided. In connection with the emergence of the operator under consideration, the latest on the telecommunication services market in the Russian Federation, the company went, only frequencies in Standard 1800 (Tele2 GSM 900 is not operated): 1710, 1725, 1778, 1784, 1879, 1820, 1873, 1879 MHz. Tele2 frequency data is used in all regions of Russia, except Moscow.

In 3G and 4G standard

Due to the high competition, among companies providing subscribers of cellular telecommunications services, tele2 was not able to get frequencies in Moscow 900 or 1800 in Moscow. We had to use the new generation 3G and 4G network (Tele 2 LTE). As a result this operator It turned out to be unavailable for phones operating only in gSM standard. Below will be presented at what frequencies there are TELE2 tariffs in Moscow (these ranges are also involved in other regions coverage of new generation networks, but are used there, first of all, to receive and transmit data on the Internet, and not for telephony):

Tele2 UMTS (3G): 1920-1935 (Transfer), 2110 - 2125 (reception).
Tele2 Internet LTE Standard 800 (4G): 791-798 (Transfer), 832-839 (reception).
TELE2 LTE frequencies in Russia standard 2500 (4G): 2680-2690 (reception), 2560-2570 (transmission).

Telecom's frequencies under consideration are relevant for 2016 and can be varied depending on the region within the above bands. A trend may be traced to the emergence of new ranges or expanding within the federal or regional level. This can occur in the case of caring from the market of one or more operator, which entails unloading of certain ranges, or when merging companies providing telecommunications services.

Signal frequency in tele2

Each of us uses mobile communications. Do not everyone know that the transmission of the signal is carried out by radio channel, frequency range which fluctuates depending on the region. Each area corresponds to their characteristics. The lower limit is 250 megahertz, and the upper 3 GHz. But other devices and techniques are used in addition to cell phones. Below we collapse in detail, at what frequencies the tele2 operates.

What frequencies operators work

For which this information is useful:

It is useful when optimizing the operation mechanisms for gaining a cellular signal level.
For a plug and suppression, it is required to operate with such knowledge.
Direct customizing mobile phone.

First of all, you need to decide on the transmission format. Three types are distinguished:

Band 7. 2500/2570 (return) - 2620/2690 (reception);
Band 20. 832/862 - 791/821;
Band 3 452.5 / 457.5 - 462.5 / 467.5;
Band 1710/1785 - 1805/1880;

The data is constantly updated and losing relevance. The listed parameters are a product on the service market. Bought and sold.

What frequencies does tele2 operate by region

Consider how the broadcasting of the best format of the provider is distinguished on the entire length of Russia.

The first allows you to cover large areas of service, and the second adapts the service in the territories of a small size with a high subscriber density. The phones themselves can be like two, so three and 4 bands are quite relevant when traveling around the world. In the TV2 GSM, by agreement with other cellular telecom operators, only the range of 1800 MHz is used, the disadvantages of which are compensated by the construction of a larger number of taps for signal transmission. In Moscow, there was no agreement on the GSM standard today.

In this regard, in the capital Tele2 is available, only for subscribers whose telecommunication devices are maintained and 4G.

In 3G and 4G standard

In connection with high competition, among companies providing subscribers of cellular telecommunications services, tele2 was not able to get frequencies in Moscow 900 or 1800 in Moscow. We had to use the new generation of 3G and. As a result, this operator turned out to be unavailable for phones operating only in the GSM standard. Below will be represented at what frequencies are valid (these ranges are also involved in other regions coverage of new generation networks, but are used there, first of all, to receive and transmit data on the Internet, and not for telephony):

Tele2 was a company with Swedish roots. Corporate principle: minimal costs, minimum prices. The operator developed well in the regions and felt perfectly until the future and competitors did not develop 3G and 4G, Tele2 could not do this. New frequency bands for this Swedes did not receive, and then they asked about the so-called technological neutrality: to turn on 3G on existing frequencies. And they were not allowed under different pretexts. Did not allowed for a long time. The Swedes lowered their hands and through intermediate structures were sold to Rostelekom. And suddenly, this black strip ended - "hit the map". Now the operator works in most regions of Russia and places even occupies a dominant position. Actually, quite recently, a Muscovite could be found exactly that only he heard nothing about Tele2.

The better the others

The first time Tele2 did the focus exclusively at low prices - and they were really like that. It happened that the arrival of this operator in the next city has fallen in it mobile communications For tens of percent.

Later - and the competitors themselves gave the reason - Tele2 the main "china" made honesty. No "stars" in advertising and description tariff plans, no secret services plugible, hidden subscription fees, expensive "premium traffic" on random sites, etc. In general, nothing such that the support service of the "big triple" is familiar to: "Well, you signed an agreement" or "you After all, they pressed the button, and there it was written below the light gray on the white. "

Sometimes a zeal of Tele2 to tell about his honesty and at the same time to prick competitors created the operator of the problem - the competitors complained about the company in FAS.

How much is

In Moscow, Tele2 has rushed around the same tariff net as in other regions, but with higher prices. However, these offers are still much more attractive than the "big triple".

There are five tariffs. The first is "orange", he is the easiest, does not imply a subscription fee, and all services in it are paid by "Pizza". Remember just: everything is worth the ruble. A minute to any Russian number - the ruble. SMS - ruble. Megabyte internet - ruble.

A series of package tariffs is followed: "Black", "very black" and "the chief". They differ in the volume of the included packets of minutes, SMS and traffic - and, of course, the subscription fee: from 99 to 599 rubles. For example, on the senior tariff per month give a thousand minutes of conversations, a thousand messages and 10 GB of the Internet. Such plans for other operators are one and a half - two times more expensive.


Tariff plan	Orange	The black	Very black	The most black	Internet for devices
Tariffication	mounted	mounted	mounted	mounted
Subscription fee	not	99 rub.	299 rub.	599 rub.	not
Pack of minutes	not	not	400	1000	not
Traffic package	not	2 GB	4 GB	10 GB	7 GB for 299 rubles. 15 GB for 599 rubles. 30 GB for 899 rubles.
SMS package		150	400	1000	not
Calls within the network to all regions	1 rub.	is free	is free	is free	1.5 rubles / min in Moscow, 1.8 rubles / min in Russia
Calls in Moscow (except Tele2)	1 rub. / Min	1.5 rubles / min	1.5 rubles / min	1.5 rubles / min	1.8 rub. / Min
Calls in Russia (except Tele2)	1 rub. / Min	1.5 rubles / min	1.5 rubles / min	1.5 rubles / min	10 rub. / Min
the Internet	1 rub. / MB	64 Kbps 64	64 Kbps 64	64 Kbps 64	1.8 rub. / MB
SMS in Moscow	1 rub.	1.5 rubles.	1.5 rubles.	1.5 rubles.	1.5 rubles.
SMS in Russia	1 rub.	2.5 rubles.	2.5 rubles.	2.5 rubles.	2.5 rubles.

After the exhaustion of the Internet package on all the "black" tariffs, you can connect the Internet from the phone: for 5 rubles a day in will give 75 MB of traffic; either "day online": 250 MB and 15 rubles, respectively. Otherwise, you will have to be satisfied with the speed of 64 kbps.

Tariffs are quite complex in the behavior of the packages. For example, all "black" provides free unlimited conversations within the network. But these conversations will be spent on the subscriber minutes. Yes, for example, a fresh "revision" of Bilayne tariffs behaves the same way. But the new player was expected transparency and simplicity. I hear how the champagne bumps off in the Yota office.

Do not think that the tariffs will be unchanged. After a set of a certain subscriber base and the achievement of the necessary profitability, Tele2 increases prices - it has already happened in other cities.

Only 3G and 4G

Unlike other Moscow operators, Tele2 will work only in 3G and 4G standards. This means that overboard remains the majority of "diagnoses" and old smartphones without support 3G. Are there any such? According to some estimates, there are about 8 million such subscribers in the capital. All of them will not be able to catch the TELE2 network. The Tele2 website has a form to check the phone model compatibility. True, at the time of publication of the article she did not work.

Only modern phones with support for 3G and 4G will work on Tele2

Where it works

Now Tele2 in Moscow and the region employs 7,000 base stations: 5 thousand in the standard 3G and 2 thousand - 4G (LTE). Judging by the map, the 3G network tightly covers the whole of Moscow except for a piece of Park Elosina Island. In the suburbs, the signal can be caught in most cities within the Moscow Small Ring.

TELE2 coating map

But the cover of LTE is frankly "holey" and does not go to any comparison with networks of other operators. But for the sake of fairness it is worth saying that at least Saita, at the start, "empty" network 3G provides speeds of 10-20 Mbps - is quite enough for comfortable mobile web surfing and even watching streaming video.

TELE2 coating map Only for 4G

Worse than with LTE, things are only covered in the Moscow metro. You can catch the Tele2 signal only at five stations: Kotelniki, Business Center, Zablakovo, Troparevo and Belarusian. They promise to be corrected in a year and a half.

Tele2 in the subway works at five stations, all of them are on the outskirts

Strange frequencies

If we talk about 4G, that is, about communication on LTE technology, the operator has frequencies at once in two ranges: 800 MHz and 2.6 GHz. The last, so-called Band 7, for users is most important, because it is supported by the vast majority of LTE devices.

Basic stations Tele2. Simple story about complex things

This article is intended for the most inquisitive Tele2 subscribers who wish to know - how to function modern networks mobile communication. We will tell you about the basic stations and the basic principles of building modern mobile networks.

| |

Each base station operator Tele2, as well, and any other cellular operator, is a whole complex of sufficiently complex and very diverse radiotechnical equipment. All elements of this complex constantly interact with each other to ensure uninterrupted cellular operation 24 hours a day and 365 days a year.

The most noticeable part of the base station is external receiving-transmitting sector antennas, which most often can be found on the roofs of various buildings, flue pipes and special antenna structures.

Antennas of base stations on the building in the center of St. Petersburg.

Sometimes the antennas of base stations can be seen on more exotic structures. For example, there are not two palm trees in the photo below, and the cellular rigs in the resort area of \u200b\u200bEgypt are captured at all. If you do not look after - you can not notice the fakes.

Tele2's company uses Nokia Networks telecommunication equipment and other major manufacturers in its network, including energy efficient and compact basic stations Flexi Multiradio last generation.

Using only modern equipment will allow tele2 to smoothly migrate from gradually obsolete networks GSM 1800 to the networks of the most progressive lTE standard In the future (more on the conversion of frequency and transition to LTE with the technical director of Tele2 Russia, Rittrans Kricrews).

Together with the antennas, special radio relay stations can often be seen on the racks that ensure the integration of the base station in the network of the cellular operator.

At the moment, more than 90% of TELE2 base stations are connected to a radio relay communication network. However, with the transition to standards that intend to provide customers with Internet access at high speeds, high-speed fiber-optic communication channels will be supplied to key base stations.

All the rest of the base station equipment is usually located at some distance from the antennas and is either in non-residential premises of the building on which the BS is mounted or in special containers, if the installation is not possible in the building.

Modern equipment for basic stations is so compact, which can fit in the case similar to the enlarged system unit A regular computer (take for example already mentioned BS FLEXI Multiradio).

To improve the connection of indoors and increasing the BS area, the signal amplifiers were often used. "Now Tele2 moves to a distributed BS, in which the radio module is located next to the antenna and produces its maximum power to it, in addition to this, losses are reduced in the opposite direction. At the same time, such assemblies can be taken from general module The BS control for a certain distance - for example, to place them around the perimeter of the roof of the building "- Rittrase Krylevis.

Coverage area Each base station depends on a variety of different factors. The most strongly on the "long-range" base station affects the height of the suspension of receiving-transmitting antennas, terrain relief and the density of urban development. However, it is not necessary to think that to ensure good coverage, the operator needs only to suspend the antennas higher and turn on the transmitters to the maximum power. In many cases, engineers deliberately limit the range of individual base stations. To do this is used different types BS: Macro-, micro, pico- or femtosotes. Especially often it happens in a densely populated area, where the need to ensure maximum capacity cellular network.

To cover relatively small territories, microsts are used. In the photo: Peterhof. Antennas are installed at the level of the fourth floor of an administrative building and provide local coverage of the park.

For example, to ensure a sufficient coverage area in an abstract urban area can be enough and one base station ( macro shot). However, as the operator's subscriber base is grown, the number of residence subscribers, in the area of \u200b\u200bthis station, can significantly exceed its maximum bandwidth. And then, during the "peak" of the load, most subscribers will definitely begin problems with the dialing (a message "Network is engaged" appears on the screen).

In this case, the operator sets several additional base stations, placing them at a low height and in the places of the highest load. Due to the uniform distribution of base stations in a densely populated area, an increase in the capacity of the network is achieved and reduced the load on each station separately. Such BSs are called microsts. The microstatic coverage area, as a rule, does not exceed 1 kilometer, and in dense construction conditions and can be at all 300-500 meters

To avoid interference, which may occur at such a dense location of stations and a limited frequency resource, all operators are forced to resort to complex frequency planning of their networks.

If the operator needs to be locally covered with a plot with maximum voice or Internet traffic (this may be a lively area at the metro station or crossroads with constantly occurring stoppers) are used low-power microstswhich are installed directly in the locations of the traffic concentration. The antennas of these base stations can be located just three to four meters from the ground, on low buildings and even sometimes, on the pillars of street lighting.

In the big cities operators, another task is solved - high-quality coverage of key places of concentration of subscribers in closed rooms. It can be trade and business centers, metro stations, hypermarkets and other urban infrastructure facilities. Providing high-quality and uninterrupted communication in such places - the task of paramount importance. Here to the aid, operators comes a special type of compact base stations, the so-called. picosoteswhich provide the necessary quality of reception and capacity of the network in the interior. In some cases, instead of a separate base station, repeater are used, relaying and reinforcing the external BS signal inside the building.

Outside of major cities, the maximum range of each base station comes out. For this, the antenna is installed on the highest masts, set up the directional effect of sector emitters (which is especially relevant for the BS of the automated roads and railways) and, if there is such an opportunity, use more "long-range" frequencies in the 900 MHz range. The coating zone of such a station can reach 32 km in normal operation.

Unfortunately, Tele2 in most regions has a license only on frequencies in the range of 1800 MHz, which leads to an increase in the cost of coating country areas - the Davy of the BS operating in the GSM 1800 range does not exceed 5-6 kilometers, which causes the operator to establish large quantity BS than in the case of using GSM 900.

The installation of such base stations that are on a serious distance from civilization is associated with high expenses from operators. It is necessary to carry out multi-kilometer power lines, to build driveways, to establish expensive towers and equipment in complex hydrogeological conditions (helicopters often use) and ensure uninterrupted operation of the BS in remote areas. Thanks to this complex work We can use mobile communications even in the most "deaf" and cut off from civilization.

"Harm" from base stations

Unfortunately, there is still a comma in society about the inevitable health problems that allegedly arise in people from the tension of the electromagnetic field created by base stations. Especially often you have to hear about discontent inhabitants of residential buildings, on which these BS are installed. Moreover, the complaints about the antennas are often starting to come even to the immediate launch of the station.

Meanwhile, residents of houses with established BS just get the least "radiation", due to the directional action of sector emitters (directly "under themselves" they practically do not "shine"). However, the inhabitants of neighboring houses are also worried about what - when entering the BS, the limit norms of the electromagnetic field from them installed by SanPiN are necessarily calculated. And these norms in Russia, it should be noted, much more stringent than those adopted in many other countries.

Computers, radiotelephones, microwaves and other homework, not to mention pressed to ear cell phone, Create a much greater electromagnetic "noise" in our homes than those installed somewhere outside the BS antenna window. To effectively reduce the level of the electromagnetic field created by mobile phone, just enough to keep it in your hands.

Never cover your palm to the upper part of the apparatus - it is there in most cases there is a receiving-transmitting antenna;
try to come closer to the windows while talking, even if an acceptable level of the network is provided indoors;
the better the network catches - the less emits the transmitter of the cell phone;
we recommend turning off Bluetooth, Wi-Fi and connecting to the Internet immediately after the end of using them.

To effectively reduce the tension of the electromagnetic field of the house, adhere to several useful habits, many of which will also help reduce the bill for electricity.

Turn off the point access Wi-Fi at night or if you do not plan to use it for a long time;
do not place the base station DECT radiotelephone and Wi-Fi Router in residential rooms, the best place for them is a corridor;
do not hold the electrical appliances included in the network if they are not used, buy a power filter with the ability to turn off the instruments separately and include them only as needed;
do not keep mobile and radio telephones at the head of the bed;
many radio telephone models have special eco-functions that reduce the activity of the radio transmitter, for example, ECO-MODE in Gigaset phones.

I would like to especially note the fact that in the urban feature operators almost never include the transmitter for maximum power, according to the reasons specified in the article. In addition, the power with which the transmitter works highly depends on the load on the BS. Base stations outside the city, which, as a rule, work at full capacity to ensure maximum range, are located at high masts that completely eliminates any harmful effect of radiation on the human body.

So, no harm from installed antennas Basic stations, of course, no and can not be, if you, of course, do not suit the picnic on the roof right under the panel emitter directed on you. However, this topic is worthy of a separate conversation, so we will tell you in detail about the imaginary harm of the antennas of base stations the next time.
