How to check whether the phone catches 4G. How to determine the frequency of cellular communication with a smartphone

To achieve the maximum speed of the 3G / 4G Internet, it is necessary to increase the signal level to the maximum, but where to see these values \u200b\u200b- will be discussed in this article.

Definition in the modem interface.

Information about the quality of the signal can be obtained almost on any 3G / 4G modem. Run the modem program or go to the web interface, in the Settings menu, select "Modem Information", in it you will see the "Signal Level" string.

In a megaphone modems, run the MegaFon | modem program, click "Help" - "Diagnostics".

Open the "Network Status" menu. In it, you will see the modem signal level (RSSI).

Using third-party programs.

Measure the 3G / 4G modem signal level. third-party programs, for example, Mobile Data Monitoring royalty (MDMA).

Attention!!! For Mobile Data Monitoring Aplication (MDMA), it is necessary to close the native 3G / 4G modem program.

You must see such a picture where the signal level will be specified on the RSSI period.

If the program worked not correctly, look at task Manager Which port uses your 3G / 4G modem.

Then create a program shortcut.

In the properties of the label, specify COM port which uses the modem.

Now you can run the program shortcut.

The minus of this program is that it is suitable for most 3G modems, but not 4G.

Determine using a tablet / smartphone.

You can measure the signal level on your smartphone / tablet, here's how to do on gadgets with android operating system.

Go to Play Market.

Using the search, find the program "Network Signal Info" and install it.

Open it after installation, select Mobile menu and on the chart or in the "Signal level" line you can see the signal level values.

Output.

All the least described not only the theory, but also supported in practice, the installation of 3G / 4G antennas, as well as based on customer reviews.

After you have determined the 3G / 4G signal level, we suggest it in the appropriate group:

1 group, from -50 DBM to -60 DBM is an excellent signal. Exterior antenna You do not need.

2 Group, from -60 DBM to -70 DBM is a good signal level. You can use a weak antenna to 15 dB.

3 Group, from -70 DBM to -80 DBM - average signal indicator. The antenna with the specimens to 15 -21 dB is suitable.

4 Group, from -80 DBM up to - 90 DBM - bad signal level. Requires antenna with medium and attachment gain values \u200b\u200bfrom 15 dB

5 Group, from -90 DBM up to - 100 DBM and less - disgusting communication quality. We need the strongest antenna 27 DB.

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 of the base 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 the service mode with the BS signal report to which you are connected.

3G parameter values:

1. 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.
   
2. 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. .
   
3. 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:

1. 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.)
2. RSSI:Basic signal power value at values RSRP.\u003d -120 DBM and below LTE connection can be unstable or missing at all.
3. 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 need to go through free registration Online.

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:

1. We change the parameter "Automatic" on "Custom"
2. 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.
   
3. 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.
4. 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.

Mobile High-Definition Link or MHL is an interface standard that combines the functionality of the MicroUSB connector and the HDMI interface. What is it needed for? Allows you to connect mobile devices to monitors or TVs, displaying a picture in excellent quality. So if you are going to connect your smartphone to the TV to display the image from the first to the last, the optimal option is to use MHL technology.

Connection is carried out using a MHL adapter. Here is one example - the company Kebidu:

Most adapters require additional nutrition, although there are those that work without additional nutrition.

Adapters inexpensive, you can buy them in many stores of electronics. But is it worth it? The fact is that not all android smartphones support MHL technology. The question is how to find out that there is support for this technology in the device?

Some users link to the MHL site (mhltech.org/devices.aspx?tid\u003d1), where you can see a list of devices that support MHL. However, at the time of writing a list, there are no many modern models of smartphones that accurately support MHL. How to be?

You can try to install Checker MHL, that is, an application for verifying MHL support. Open Play Market.

In search Write mHL Checker, Press the search button.

Choose from the list, let it be Checker for MHL (HDMI). Install.

Run. Press the Check MHL button (HDMI).

See if your device can support technology or not. In our example can.

However, in responses to such applications, you can find messages that those are wrong. Is it or not, it's hard to say, so you can only solve you. In our opinion, the only true way to check whether there is support for MHL on the smartphone, it is used to use the adapter and connect the smartphone to the TV.

Although all the advantages mobile communications Recently, they seemed fantastic, today it is no longer surprising. Therefore, communication and exchange of a huge amount of data requires new information transfer standards. Now such possibilities exist. They are called 4G, that is, the fourth generation of cellular communication.

4G allows you to transmit in mobile networks both voice data and multimedia information at high speed, up to 100 Mbps with subscribers in motion. The data transfer rate in stationary subscribers is an order of magnitude higher. MegaFon is actively implementing 4G and 4G + technology. Therefore, today 4G Internet MegaFon is one of the most sought-after offers.

What is 4G internet from megaphone?

Cellular communication MegaFon today offers data transfer service in mobile networks with a huge speed, it is called 4G + from megaphone. By connecting 4G +, especially with the support of LTE-Advanced technology, you can watch any photos and videos, listen to music on your mobile device without delay. Even the video in FullHD will be downloaded in a few minutes. This becomes possible due to high speed - up to 300 Mbps.

You can take advantage of the quick mobile Internet in 77 regions of the Russian Federation if you connect 4G +. When using 4G + with LTE coverage, the coverage area is less than 23 regions. Although 4G + with support for LTE gives a greater speed, in some cases 4G + preferably, since the number of devices capable of working stably in the networks 2G, 3G and 4G, yet more.

If you live in Moscow or Moscow region, St. Petersburg, Rostov, Chelyabinsk, Krasnoyarsk, Nizhny Novgorod, Samara, Ufa, Perm, Yakutsk, Lipetsk, Sochi, Sakhalin, Vladivostok, Tula, Ivanovo, Rostov, then you can connect 4G Internet from megaphone With support for LTE-Advansed technology. A complete list of cities in which this service is available can be found on the official website of the company MegaFon. There is also a coating map.

How do you know if you have 4G Internet megaphone?

To do this, make sure that your mobile device is operating in the network megaphone 4G +. You can do this with a smartphone by typing a combination of numbers: * 507 # and pressing the call button. You can also go to the megaphone site, at http://moscow.megafon.ru/internet/4g/#check4g

In the check form you need to enter your phone number and click the "Check" button. After that, the message in which will be specified on your phone number will be indicated whether your mobile phone and sim card standard 4G + Internet from megaphone supports.

If the SIM card does not work with the fourth generation of mobile communications, it can be replaced with another, capable of working in 4G +. This can be done by visiting any salon of MegaFon. The replacement service is completely free. If the 4G + standard is not supported by a smartphone, the output is only one - to purchase a new mobile phone.

How much is 4G + internet from megaphone?

For different mobile devicesSuch as a smartphone or tablet are available to different Internet packages, as well as for modems or routers. For example, now for the smartphone there are three tariff packages: "Internet S", "Internet XS" and "Megabeslimit".

Subscription fee For "Internet S" is 350 rubles per month, and the amount of information is limited to a number of 3 GB. Use the Internet B. this package You can throughout Russia. Package "Internet XS" costs 7 rubles a day, with a limit of traffic at 70 MB per day. "Megabezlimit", respectively, with the title, allows not to limit yourself in the information received. The amount of subscription - depending on the tariff plan.

How to connect 4G + internet from megaphone?

You can do this in several ways. For example, directly from your smartphone. To do this, you need to enter a combination * 105 * 1153 * # and press the green challenge button. Also connecting the Internet can be ordered by sending an empty SMS to the 05001153 number. On the megaphone site, you can connect 4G + as from personal Cabinet, affordable after authorization and in the form of a quick connection. To do this, you need to enter your phone number and click the "Connect" button. After that, the code will come to your number by which you can confirm the operation.

Not all users are well versed in the technique and communication standards. At the same time, advertising on the Internet, on television and radio shot by various slogans and slogans that a particular smartphone supports one or another function and has certain capabilities. The situation is quite everyday, firms that sell sales should make a profit and actively promote their products.

A special popularity is gained cell phones 4G. Technologies do not stand still, and besides, they become cheaper and easier to produce and maintain their scale.

So, how to find out if the 4G phone support? detailed instructions - Next by text.

What it is?

Before answering the question of how to find out if the 4G phone supports, it is important to determine what it is about what exactly is. As a rule, under this term implies a modern communication standard that provides increased data transfer rate when using mobile Internet and high quality With ordinary calls.

4G is an abbreviation from of English languagewhich is translated and decoded as a "fourth generation". Accordingly, before it was more early versions Communication protocol, such as 3G, which has been advertised no less active than its succession.

This technology is based on elevated bandwidth Mobile network, and, as mentioned above, allows you to use mobile Internet At speeds comparable to a full-fledged Internet.

How to find out if the 4G phone supports?

There is enough a large number of ways to do it. The easiest - open the instructions of your smartphone and see which it supports the communication standards and is subject to 4G list. Very often, several separate pages are dedicated to this, which are also indicated in the content.

However, there are other ways to answer the question "how to find out if the 4G phone supports." For example, it may be an inscription on the box of your device. Typically, the manufacturer indicates this feature for promotional purposes (it is quite popular and began to appear even in budget models of smartphones). Sometimes instead of the 4G abbreviation, you can find LTE or WiMAX inscriptions. These are a bit different technologies, but both are actively used in the new generation communication standard.

If you buy new smartphone And you need a description described, it is better to be restrained and just asked the consultant to display 4G support phones or to clarify the availability of technology on a specific device. Sellers are interested in selling you any smartphone.

How to check whether 4G works

Everything is very simple, regardless of the operator of communication and operating systemThe phones that support 4G communicate the user about the type of the connected network. Usually, such data is located in the upper corner of the screen, next to the battery charge indicator. By analogy with the inscription packaging may contain the following information: 4G, LTE, WiMAX. However, the alerts can also be in the hidden menus or settings. Information related to such indicators should also be placed in the instructions.

Tariffs and operators

If you are confident that your device supports 4G, but for some reason it does not work, it is possible that the selected tariff or telecom operator does not provide such services. What to do in this case? Try to call technical support or come to the sales office, consult and choose another tariff. If 4g is not at the operator itself, then it will be necessary to replace it. It is possible that in some regions this communication standard is temporarily not supported for any reason by any provider of communication. In this case, it will have to use more conservative 3G, and it works on all devices where there is 4G support.

There are other cases, such as incomplete network coverage. May temporarily not work the Internet or even mobile network. This problem is quite a normal phenomenon, and the coverage of the links is growing every year in geometric progression, as well as quality.

An example of devices with 4G

This communication standard supports the entire iPhone line, starting with the fifth model. There are nuances associated with specific chips and operators, but again, every year the relevance of this problem is reduced, and manufacturers and communication providers come to a compromise. As for other devices, they include all samsung flagshipsStarting with Galaxy S5, and some earlier models, as well as gadgets from other manufacturers.

Recently, the technology is spread faster, and 4G supporting phones are becoming cheaper. Even budget models that are sold for a small price, increasingly have a similar function.

RESULTS

Time flies very quickly, so 4G support phones become quite an ordinary thing. However, for some ten years, the like happened to many other functions and innovations, for example, colored thin displays, cameras, sensors, and the wide distribution received powerful processors capable of processing even high-quality 3D graphics directly on the mobile device.

As mentioned above, the answer to the question "How to check whether the 4G phone supports" Do not make difficulties even in inexperienced users of smartphones, since modern devices do not contain any hidden functions. About the presence of any popular technologies, a potential buyer will find out or from advertising, or at the time of acquiring a new gadget, because specifications And the specification is the second that the client sees after the cost of the goods.
