How to strengthen a cellular signal. What does a cellular signal booster kit consist of? Checking the signal level

Tele2 is a Russian operator known for extremely attractive prices for calls and mobile Internet. This pricing policy has provided Tele2 with a significant subscriber base throughout Russia. Low prices on Tele2 services is expectedly reflected in the number of Tele2 base stations, which, in turn, can lead to signal deterioration. And this already means interruptions in voice communications and a drop in mobile Internet speed. How to use Tele2 services and not experience difficulties with signal reception? The only right decision would be to buy a special Tele2 amplifier.

What is the Tele2 amplifier?

Amplifiers are a general name for a number of devices for amplifying the GSM/3G/4G signal. Depending on the area in which you need to strengthen the Tele2 signal, the initial level of the Tele2 signal, the type and number of devices on which you need to receive amplification, the type of signal that needs to be strengthened. In this section you can buy the most popular amplifier kits for Tele2. Tele2 amplification is achieved by these kits using a different set of equipment - antennas, repeaters (repeaters) or routers. You can also buy all components of the Tele2 amplification system separately on our website.

Operating principle of the Tele2 amplifier

The antenna for receiving the Tele2 signal is installed in a location carefully selected by our specialist. The placement location is determined by measuring the initial Tele2 signal level. The antenna receives the signal and transmits it via cable to a repeater (signal amplifier) or router (if the use of a separate amplifier is not required). As a result, at any point in the amplification zone you will receive a stable, confident Tele2 signal.

In villages, until now, in most cases there is no dedicated Internet line. It happens that the Internet can be connected via an ADSL line if you have a connected landline phone.

In most cases, all Russian villagers connect to the Internet using 3G modems. And the further the village is, the worse not only the 3G Internet, but also regular cellular communications.

To improve communication quality, the following amplification principles are used:

Using an antenna.
Using an antenna and amplifiers.
Using multiple antennas and multiple amplifiers.

There are ready-made kits, but before you buy them, you need to determine what to strengthen and how. Sometimes one antenna is enough, and sometimes not.

You need to know exactly in what range the 3G signal of the selected telecom operator is transmitted, and where the boundaries of this signal are. To check the signal strength, a regular cell phone or spectrum analyzer will do.

Checking the signal level

Before you can strengthen anything, you need to catch something. We determine the range of operating frequencies for voice communications and the Internet. The image above illustrates the entire range of frequencies involved: television signal, wi-fi, DECT, GSM, LTE, etc. It is important to understand in what range the base station at the point being tested transmits the Internet. It can be transmitted in the UMTS 900 and UMST 2100 standard.

In Russia, the 3G signal has its own standard: UMTS 900 and UMST 2100.

All smartphones and 3G modems work using both of these standards. In cities due to the small coverage radius, but more high speed signal transmission and stability of operation with a large number of connections, use the UMTS 2100 standard.

If you are not an installation organization specializing in installing 3G boosters, you can use a phone with 3G support for a one-time connection. We activate the built-in Netmonitor function in it.

How to do this on your phone, look on the Internet. I will give the most common codes.

Phone model	Menu entry code	Note
Apple iPhone	3001#12345#, press “call”	2g, 3g, 3gs, 4g, 4gs, 5. For firmware versions from 5.0.1 and higher.
Android	#0011# or ##4636##* or ##197328640##	The menu should appear automatically after entering the last character, if not try another code
HTC (EVO, Incredible, Touch)	##33284#, press “call”	In the menu, select the network and see the signal level
HTC Wizard 8125, 2125	##364##	The signal level is displayed in conventional values. The higher the value, the higher the signal level
HTC Touch	##33284#	—
Samsung C170, X820	#99990#	—
LG C900	##634#	If it asks for the password 2277634#*# and press ENTER
Nokia 6215i, 6315	##2773	then code 000000

When we enter the engineering menu, various information appears, for example, volume level, battery charging, IMEI, wi-fi, phone usage statistics. I don't recommend changing the values.

If you can't find the settings you need, try another phone. Finally, you need to determine the Rx CH parameter. The first value surrounded by a red frame shows in which range the signal is received. If the value is within 10562-10838, it is UMTS 2100, if within 2937-3088, it is UMTS 900. Having determined the operating range, you can accurately select a 3G signal amplifier, for example, high-quality Picocell 900 or Picocell 2000.

The yellow frame shows the 3G signal reception level. Having constantly changing dynamic parameters of the signal level, we are looking for the point of best reception. Less is better. Ideally, it is better to place the antenna higher on the roof, but you can find points of reliable reception inside the house.

Equipment selection

If you are in a reception area, installing a good antenna with high gain may be sufficient. For example, the antenna AP-1900/2700-17 with a gain of 17 dB, but a narrow radiation pattern. Suitable if there is one base station installed near you and there are no other signal consumers nearby.

Directional antenna AP-1900/2700-17 for signal amplification cellular communications

A fantastic result is shown by the AO-2000-11 antenna - with a high gain = 11 dB and a circular radiation pattern. It works on the set it and forget it principle. Its advantage lies in the principle of operation. It can catch a signal from several base stations at once, which significantly affects the speed of the Internet. No need to look for the direction of the signal.

Omnidirectional antenna, model AO-2000-11 to amplify the 3G signal

In almost 80-95% of cases, when a 3G signal is at least somehow caught, it is enough to screw a 3G amplifier-repeater TAU-2000 from Picocell to the antenna, and you will receive a stable 3G/4G signal.

To prevent signal loss between the antenna and the amplifier, I recommend using a cable with a large cross-section, the ends of which are crimped industrially or a special tool.

Ready-made kits

When you know exactly what type of amplifier you need and whether you need it at all, you can start purchasing equipment. If there are no retail outlets in your city, buy from online stores or directly from the equipment manufacturer.

Kits can be of several types:

without amplifier;
with amplifier;

Let's look at kits without amplifiers. Such kits include an antenna and wire. Conveniently, if you have a modem or router, then the cost of strengthening the 3G/4G signal will be minimal. A set of wire and antenna will cost you from 5,000 rubles.

Antennas are selected based on the terrain, number and distance to base stations. This kit can always be expanded with an amplifier; the final price of the equipment will increase, as will the quality of the received signal.

You can use any antenna, including those given when selecting equipment, but it is better to buy a modem Huawei E392, although its price starts from 3,200 rubles.

Watch a short video of everything outlined in the article; if anyone is interested in the intricacies, go to the site indicated in the video.

And finally, I will share an observation: buy an antenna and equipment in specialized stores, and not in cellular communication stores; what they sell there does not work.

The Connect antenna is made for the beauty of the interior. The usefulness of this device is questionable. Can only be used as an extension cord for a modem

Ask questions if anything is unclear. Good luck with your shopping.

We find ourselves in various situations in which the speed of mobile Internet is important, this article is about how to improve Tele2 Internet on your own.

I wrote an interesting article about how I do it, I recommend you read it first. As of today (information updated on March 22, 2018), Tele2 provides services using 4G, 3G and 2.5G (or EDGE) technologies, each of which has its own speed limit and coverage area. The map can be viewed on the operator’s official website.

In fact, the average speed usually does not reach the maximum.

True, there are cases when the Internet drops to almost 0. At the same time, Internet access is very, very necessary. What to do in such cases? This is exactly what you can find out further. The article describes the main methods of amplification, but they are focused more on the modem. What should we do if we use the Internet from a phone?

This is what the operator himself advises, and we will add it.

Tele2 Internet speed, like all operators, depends on a number of factors.

Weather.
Distance from the base station.
Load of the base station and the network as a whole.
Subscriber's end equipment.
Tariff plan.
Operator actions.

We cannot influence weather conditions. Likewise, we cannot influence the load on the base station. The distance to the BS can be reduced, but in 99% of cases it will not be convenient. It turns out that we can influence tariff plan and subscriber's end equipment. If your plan includes a limited amount of data, check how much is left. If the entire package is used up, the problem is solved by purchasing additional GB (). You can read about which ones in the corresponding article.

Why are the operator’s actions listed as a separate paragraph? Information has been circulating on the Internet for some time that the above-mentioned unlimited tariffs Tele2's are not so unlimited. Look at the photo. It is stated that this is an instruction for support workers.

It turns out that there may not be any other reasons for the drop in speed. Note that there are quite a lot of complaints from subscribers about the quality of Tele2 Internet on the network. If you experience problems frequently, this is a reason to think about changing your operator.

Now let's look at how to work with subscriber equipment.

We offer 5 ways to strengthen the signal on your mobile phone to increase the speed of Tele2 Internet (suitable for all smartphone models).

It is best to place the phone near the window. In addition, if you are below the 5th floor, raise the phone higher, if above the fifth floor - lower. This is due to the fact that any obstacles create interference, the signal is lost, and the speed decreases. In the case of the 5th floor, we slightly reduce the distance to the nearest base station.
Reboot your phone. Depending on the phone model and operating system, the firmware may react differently to events on the network. In some cases, rebooting the phone significantly increases speed. It will also be useful to close unnecessary tabs in your browser and clear the cache.
If there is a metal vertical plate next to you (1M by 1M or more), then you can bring the phone to it at a distance of 3-5 cm. From my own experience, I can say that the speed can increase 10 times! If possible, the plate can be rotated, since it will give the maximum effect when positioned perpendicular to the waves.
Try moving the SIM card to another device (I can tell you from my own experience that the Internet works faster on a tablet than on a phone). Here you can show your imagination, depending on what equipment is available to you. For example, you can install a SIM card in your phone and . OPTION FOR COTTAGES. If the phone can be connected as a router, it can be placed on the roof of the dacha, thereby ensuring the maximum signal level. All that remains is to supply power to it.
Try it if this option is available.

It happens that we use mobile Internet while on the move. When driving more than 10 km/h, the speed of mobile Internet decreases by more than 10 times. You may just need to pause to load the page.

By the way, since the mobile Internet often breaks, it is recommended to use programs that support resuming files when interrupted. There are many different download managers; they can be found on the Internet. We do not recommend using torrent to download files, since Tele2 reduces the speed in such cases if you have not taken care of bypassing the blocking in advance.

Let us separately mention the features of 4G:

Your SIM card must support the standard. To check this, dial *156#.
The smartphone must support operation with the frequency appropriate for the region. The range of the device is indicated in its technical specifications, and the broadcast frequency can be found out from the operator.

You can also try optimizing your download speed programmatically.

There are several applications for smartphones that speed up the connection:

Internet Booster for 3G on Android;
Speed-Up-Internet 4G for Android;
3G Network booster for iPhone.

That's all. If you have anything to add to the material presented or you find inaccuracies in the description, please indicate it in the comments.

Is it necessary to purchase an expensive gadget when you can get by with a device assembled from improvised materials?

Those who have at least an initial level of knowledge in the field of cellular communications will be able to cope on their own. To do this, you need components and tools, as well as a diagram of the device.

And you can assemble a simple cellular communication amplifier on your own. What is required for this will be discussed below.

Antennas for amplifying cellular communications

They are one of the simplest devices that allow you to achieve a high-quality signal at any object.

There are two main groups of antennas:

External;
Internal.

The former are usually installed on the roof of a building and are capable of providing coverage over large areas. The antenna transmits the signal received from the base station through a cable to the amplifier. This guarantees good quality communications even in areas where it was previously impossible.

What elements does the signal amplification system consist of?

It is possible to ensure reliable communication in places that are difficult to reach for a radio signal, but this will require special equipment. Collected in unified system various devices allow you to achieve High Quality signal and forget forever about its sudden disappearance. It is often called a cellular booster. However, in reality it is a complex consisting of the following elements:

A repeater or two-way amplifier, which is an intermediate link;
External and internal antennas that pick up the station signal and distribute it indoors;
Power divider or wire splitter;
N-connectors;
Coaxial cable with a resistance of 50 Ohms.

All devices included in the system are divided into two groups:

Active;
Passive.

The first includes devices that require a connection to a power source to operate - this is a repeater, connectors. Antennas, divider and cable are called passive. Each system is designed for a specific object and therefore may have a different number of amplifiers and internal antennas. The best option it is considered to be one that uses a cable of minimal length, since every extra meter is a loss in signal quality. This must be taken into account when assembling a cellular signal amplifier with your own hands.

Since all the elements are interconnected, it is recommended to install the equipment before finishing, so as not to spoil the interior.

Repeater operating principle

Equipment of this class is in some way a repeater. It processes received signals and sends them to the base station tower if it is an outgoing call. When a subscriber is dialed, the repeater performs the same function, only the connection is made with the user’s gadget.

Let's watch the video, the simplest way boost the signal:

Signal reception and transmission is carried out by antennas. The simplest cellular network signal booster can be assembled with your own hands. The outdoor antenna receives or sends it to the station, and the indoor antenna is responsible for expanding the coverage area indoors.

How to make a cellular booster with your own hands

Using such a device allows you to achieve high-quality communication in almost any corner of the facility. A repeater is especially necessary in areas with poor signal or where there is no signal. The advantages of using the system include the following:

Strengthening the signal in places where there are frequent interruptions in mobile communications;
Removing interference;
Increased message clarity;
Reduced radiation levels;
Longer phone battery life.

But since such equipment is not cheap, many decide to make it themselves.

Let's watch the video, the stages of making it yourself:

In order to assemble a cellular communication amplifier on your own, you will need components that need to be connected into a single system. How to do this will be discussed further.

What is needed for assembly

If you decide to make the simplest device, namely an antenna, then you will need:

Wire, but not copper (length 30-40 cm);
Connection block;
Cable (up to 10 m);
Fasteners (for mounting connecting blocks);
Polymer pipe (20 cm);
Plastic.

Since during the work you will have to connect individual elements, it is worth having electrical tape on hand. After all the components have been found and prepared, you can begin assembling the amplifier cellular signal with your own hands.

A piece of wire must be bent in the middle by 90°, so that the end result is a rhombus. To do this, retreat 9 cm from the center in both directions. Then, at the mark, the wire is again bent to the same angle. As a result of the manipulations performed, you get a rhombus. The ends are bent inward and a block is connected to them. Install it so that future connections can be made through it. To do this, cut along one side of the polymer pipe and make a hole on the opposite side.

Watch the video and make an amplifier from cans:

After the antenna assembly stage has been completed, we begin to connect the coaxial cable. At one of its ends, the outer insulation is removed and the outer and inner conductors are connected to the contacts of the connecting block. As a result, the cable becomes an extension of the antenna.

After this, all that remains is to install the device on the roof of the house or attach it to a pole and point it towards the base station of the cellular operator. The last step in making a simple amplifier with your own hands is to connect the other end of the cable to a plastic plate. And you can start testing.

If everything was done correctly, then as soon as you bring your mobile phone to the amplifier, the signal indicator will increase by 2 or 3 bars.

Selecting a repeater installation location

But it’s not enough just to assemble a cellular communication amplifier, you also need to install it correctly. The efficiency of such equipment is directly dependent on its location, as well as the antennas included in the system. Therefore, before proceeding with installation, you must make sure that the signal level is sufficient. The easiest way to find out is by making a call from your phone where you plan to install the antenna. You can also determine the signal level by the indicator on the gadget’s display.

Antenna installation

But besides this, there are other restrictions. For example, the place to install the amplifier should not be closer than a meter to heating appliances.

After planning the location of all components, begin laying the coaxial cable. But before turning on the repeater, you need to make sure that all connectors are intact and clean. Do not turn on the device if it is not connected to an external antenna, as it may be damaged. If you need to disconnect the RF cables, be sure to turn off the power.

There are also restrictions in temperature conditions. If for an external antenna it ranges from -40 to +50°C, then for the repeater itself it is limited only to positive temperatures. In addition, the repeater can only be installed in a heated room.

We must remember! An incorrectly assembled system can emit interference, which affects the operation of nearby stations. Therefore, you should not install it without examining the site and determining the location for all the blocks.

Amplifier settings

In order to obtain a stable and sufficiently strong communication signal at a specific facility, it is necessary to correctly perform all commissioning work. They consist of adjusting the quality of voice messages and eliminating self-excitation of the device.

Watch the video, what to do if bad signal, look at the solutions:

The first thing to start with is to make sure that all connections are intact. The power adapter and antennas are connected to the high-frequency connectors. If power surges frequently occur in the network, then it is necessary to use a surge protector.

The next step is to adjust the gain. It must be at least 15 dB. The repeater can be configured manually or automatic control. In the first case, adjustment is carried out using the potentiometer knob and changing the position of the external and internal antennas.

Automatic tuning involves setting the gain level so that maximum output power is obtained. In this case, the device will independently adapt to the traffic of the operator’s base station.

Network coverage mobile operators not continuous. And no one will make it continuous - it is economically unprofitable. A certain contribution to this is made by the peculiarities of the propagation of radio waves, which is why zones of radio silence may arise at certain points. Poor cellular signal reception - this problem relevant for many people, especially for those who live outside the city, far from the nearest base stations. Let's try to solve this problem together.

Reception situation

There are thousands of complaints about cellular operators on the Internet - people complain that they have problems with communication. Unfortunately, no one will make sure that the signal is received everywhere and with the same strength. This is impossible due to economic reasons, this is impossible due to some physical reasons. Russian operators in general they work well, and their coverage area is decent - this is confirmed by evaluative comparisons with European operators. You're just a little unlucky with the location.

If you complain about the poor signal level of MTS in your area, nothing prevents you from interviewing your neighbors and finding out which operator they use. It is quite possible that Beeline or MegaFon will work much better for you, delighting you with stable reception. Even Tele2, which is not always distinguished by a wide coverage area, has significantly increased the coverage of its networks in recent years - you can try.

Transferring a number to another operator

You can object - they say, I don’t want to change the operator, even if the signal from another operator is picked up many times better. This is called “to spite my neighbor I will freeze my ears.” Don’t change if you don’t want to – sit in the wilderness and rejoice in the lack of communication. For others, we can offer a reasonable solution - if in your area MTS is not detected, but Beeline is caught, go to the Beeline office and write an application to port the number.

Advantages of this approach:

In just 8-9 days your mobile phone will be working - it will be serviced in the network of another operator, and you will forget what poor network coverage is.
You can choose a more profitable tariff plan.
You will remain with your number - there is no need to change it at all.

This is the best way to deal with poor cellular signal reception, but it will require preliminary research - you need to decide which operator works best in your area.

Buying another phone

This is not to say that this is the most optimal way to solve the problem of poor signal reception. All modern tubes have approximately the same sensitivity. Therefore, buying another smartphone may result in unnecessary expenses. And the talk of Apple fans that iPhones “catch anywhere” is nothing more than a myth.

Finding a phone with high sensitivity for poor reception conditions is problematic. A few years ago they existed, but then they disappeared somewhere. People living in remote areas are advised to look for old Cell phones Nokia and Motorola - they were distinguished by increased sensitivity.

DEXP Larus X2 rev.2.
BQ Rome BQD-2051.
Termit FixPhone v2.

Their cost does not exceed 3,000 rubles, and antennas protruding from the housings will provide increased sensitivity.

The most difficult problem to solve is the reception of 3G and 4G signals, since only modern phones work with them.

Using external antennas

External antennas will help improve the quality of voice communications and increase the speed of mobile Internet. They connect to phones equipped with appropriate sockets. Unfortunately, a very limited number of models are equipped with them. Let's see which handsets we can connect external antennas to to improve cellular network signal reception:

Huawei ETS5623 is a landline cell phone complete with a remote antenna and a 10-meter roll of cable. Cost - about 4 thousand rubles. An excellent solution for poor cellular signal reception.
Runbo H1 is a very expensive smartphone costing almost 60 thousand rubles, made in a shock-resistant and waterproof case. It is equipped with a connector for an external antenna.
Kit MT3020B is another stationary device, equipped with a socket for an external antenna, which is supplied in the kit. The cost of the phone is about 5.5 thousand rubles.

We also recommend paying attention to handsets of the last decade - they were often equipped with connectors for antennas (including those hidden under the back cover) for working in conditions of poor cellular signal reception.

Cellular communications are needed not only for voice transmission, but also for access to mobile internet. And if we cannot find a smartphone with a connector for an external antenna, then there are plenty of 3G and 4G modems with them. Literally every second modem can be connected to an antenna, which will significantly improve the quality of reception.

Passive repeaters

The use of passive repeaters allows you to improve cellular signal reception without expensive electronics. Most often these are homemade devices, consisting of a bunch of two small antennas. Beer cans, copper wire, and some other unimaginable household products are also used in the designs. All this is not serious, and it also limits freedom of movement around the house - you have to talk on the phone while directly next to such a repeater.

There is one more interesting technical solution. If your smartphone does not have an antenna jack, you can do the following:

Buy one directional GSM antenna and one GSM whip antenna.
Install a directional antenna on the roof of the house, on a tree or pole up to 10 meters high (the larger the better).
Install a whip antenna in your home.
Connect both antennas with a cable.
