Can't decide on a cellular operator? Then this program is just for you!

Characteristic

With this program you can monitor the network of a mobile operator. Who needs this and why? First of all, you can find out the location of the towers of a specific operator. This will allow you to determine its so-called coverage area.

In addition, this will allow you to establish the quality of the connection.

It is noteworthy that the program provides the ability to use its own database. It contains detailed information about the location of all base stations.

Among other things, this software can keep a log. Thanks to this, all data will be stored in a separate file.

It is also worth noting that the utility can run in the background.

It is noteworthy that despite the rapid development of technology, some of the data provided by the program may be inaccurate. Information is provided by Google services.

An interesting fact is that in emergency circumstances this application can save lives.

For example, it will help you find the network if you are lost deep in the forest and need to make an urgent call. You will always know where to go to improve the quality of communication.

Description of the Autostart And StaY program:

The program "Autostart And StaY" is a manager for autostart applications on the phone. The main function of the program is to block startup applications. However, for netmonitoring, the option of setting any third-party application to autorun is more useful.

Install the application, select “Netmonitor by parizene” from the list, check the “Autostart (autostart after switching on)” and “Stay (keep the application running)” checkboxes, start the algorithm by clicking on “Service Toggle”.

After restarting the device, "Netmonitor" will automatically start and log recording will begin. Even if for some reason the work of "Netmonitor" is completed, the application will start again.

Netmonitor is a tool for displaying technical data about the state of the cellular operator's network. Allows you to determine the level of the operator’s input signal and the channel numbers on which the operator operates, the type of network and basic parameters.

In a regular mobile phone, this function is most often available by typing a special key combination similar to a USSD request.

This information is mainly used for correct selection and installation.

Activating the Netmonitor menu for various phone models:

Apple iPhone 2g, 3g, 3gs, 4g, 4gs, 5 - firmware version 5.0.1 and higher:
*3001#12345#* then press “call”. We get to the Field Test menu. In the upper left corner you can see the signal level of the mobile operator, reflected in dB. Next to the GSM Cell Environment/GSM Cell/Neighboring Cells tab, you can see a list of channels. Total 6 channels. In order to view information about the channel, click on the arrow.

ARFCN (Absolute radio-frequency channel number) is the channel number.

An ARFCN value in the range 1-124 or 974-1024 means that the operator operates in the 900 MHz range and we need (900 MHz) or a GSM900 repeater.

An ARFCN value in the range of 512-886 means that the operator operates in the 1800 MHz band and we select an 1800 antenna or a DCS1800 repeater.

Downlink Frequency - channel number by which the carrier frequency is determined.

If the channel value is in the range 2937-3088, then it is 3G/UMTS900 - and we need a GSM900 antenna or GSM900 repeater.

If the channel value is in the range 10562-10838, then it is 3G/UMTS2000 - select a 3G antenna at 2100 MHz and a WCDMA2100 repeater.

We recommend viewing information on several channels. Also, information on this definition of channel numbers will be more reliable if these measurements are taken during a connection with another subscriber (incoming or outgoing call). You must understand that the phone displays all values ​​only for the cellular operator whose SIM card is inserted into the phone at the time of measurements! And if you want to install for two or more mobile operators, then you need to do all the measurements with each SIM card!

Netmonitoring programs for smartphones based on Android OS:

Any smartphone running Android OS is suitable for installing programs (or almost any smartphone; we do not recommend using Chinese iPhones on Android). The Nexus series devices performed well (primarily due to the latest version of the Android OS), as well as the HTC Desire - the netmonitors on these devices show the maximum possible information. Devices of other brands and models will also work, but may not display some additional information (for example, a list of nearby base stations, which is described in more detail below).

If you already have a smartphone, half the work is done. You need to install a netmonitor program. There are not many of them, and there are almost no good ones at all. Here are some of them that can be found in Google Play Market:

• Network Monitor
• NetMon - Radio Network Monitor
• Netmonitor
• G-MoN
• GSM signal monitoring
• G-NetTrack
• Network Monitor Light

All that is required of the programs is to correctly display the parameters we need to monitor the network and save them in a readable, machine-processable log, along with, in some cases, GPS coordinates.

Application Name	Description
Network Monitor	Does not show neighboring cells, the interface is uninformative.
NetMon - Radio Network Monitor	Can show neighbors and signal levels. Keeps a completely adequate log. But with LTE the program clearly let us down - it does not provide the necessary data.
Netmonitor	The simplest interface, shows neighboring GSM cells, displays signal strength, keeps a log. In UMTS and LTE it behaves adequately and provides all the necessary data.
G-MoN	Informative interface, displays neighbors, displays the necessary data in LTE, and keeps a detailed log.
GSM signal monitoring	There are neighbors, everything is fine with 3G, but LTE does not provide the necessary data.
G-NetTrack	Everything is fine with this program, but in LTE it does not show the necessary data.
Network Monitor Light	The application is a kind of triumph of primitivism. Sent to the landfill due to the lack of necessary data in LTE (although even if they were there, I would hardly be pleased to use this program).

What to monitor?
To begin with, let's define the task - we need parameters that uniquely define the base station, or rather, a specific sector (cell) of the base station or other minimal positioning cell in the mobile network.

Detailed description of common types of mobile networks and display in netmonitor:

GSM

GSM, Global System for Mobile Communications- Global System for Mobile Communications. Second generation network. In Ukraine it is used in the following frequency ranges:

GSM-1800

Also called DCS (Digital Cellular Service).

The following parameters exist in the GSM network:

Parameter	Format	Description
MCC	3 decimal digits	Mobile Country Code, Code of the country. Unique country identifier (full MCC list).
MNC	2-3 decimal digits (leading zeros matter, 01 and 001 are different codes)	Mobile Network Code, Mobile network code, Operator code. Unique in a country with MCC (see list by country on Wikipedia or on the website of the International Telecommunication Union (ITU, International Telecommunication Union)).
PLMN ID	MCC + MNC 1, 5-6 decimal digits	Public Land Mobile Network Identifier, Public Land Mobile Network Identifier. It is the first 5-6 digits of the IMSI number of the SIM card; in netmonitors it can be simply designated as a network.
L.A.C.	16-bit integer	Location Area Code, Area code. Unique within the operator's network with the corresponding MNC.
CID	16-bit integer	Cell Identifier, Cell ID. Unique within an area with a specific LAC.
T.A.	6-bit integer (0 to 63)	Timing Advance, Temporary Lead, Advance Synchronization. An indicator of the time delay of signal passage. Increases by 1 as the distance from the base station increases for every 550 meters.

Thus, we obtain a hierarchical chain of identifiers MCC-MNC-LAC-CID (PLMN ID-LAC-CID), where all parameters are important to uniquely identify a cell in the world. And these are the parameters that any netmonitor shows us.

If the netmonitor shows the TA parameter, then you can approximately (in gradations of 550 m) set the distance of the mobile station from the base station. This can be useful for positioning if the exact location of the tower is known.

In the GSM network, base stations (BTS, Base Transceiver Station) transmit to mobile stations (MS, Mobile Station - designation of mobile phones, modems, etc.) not only information about the cell in which the MS operates, but also a list of neighboring cells ( NCL, Neighbor Cell List). This list is configured for each cell when setting up network parameters and serves to correctly carry out the procedure for MS transition from one cell to another (such a transition is called handover or handoff, read more).

Netmonitor applications can display a list of neighboring cells, although this does not work on all smartphones.

UMTS

UMTS, Universal Mobile Telecommunications System- Universal Mobile Telecommunication System. Third generation network. In total, there are 26 frequency bands in the UMTS network, two of which are used in Ukraine:

Number	Range name	Transmission range, MHz	Reception range, MHz
1	2100	1920-1980	2110-2170
8	900	880-915	925-960

In UMTS networks, such a concept as Cell is not defined. Instead, the concept of Service Area (SA) appears. Each service area may consist of one or more physical cells (cells or sectors, similar to GSM), i.e. can be served by several base stations (NodeB) simultaneously (this, by the way, is one of the main fundamental differences between third-generation networks and their predecessors). Each cell, in turn, can be included in more than one service area. Those. service areas may overlap.

Modern devices can simultaneously connect to three physical cells, which helps provide the so-called procedure. seamless or soft transfer (softer handover, soft handover), without breaking and re-creating the channel.

The comparison of service areas and cells occurs transparently, i.e. invisible to the data network and, accordingly, to netmonitors.

Returning to the parameters that we need to fix, in UMTS networks MCC, MNC, LAC are important to us, as well as:

For netmonitoring, the difference is only in the name - the CID has changed to SAC, the other parameters remain the same, and the unique cell number (in this case, the service area) looks like this: MCC-MNC-LAC-SAC.

Netmonitors usually do not differentiate in designation, and the service area code is shown as CID.

As for the list of neighboring cells, it is also present here and is called Neighboring Set. However, the neighboring cells here are just physical cells, each of which is identified by a non-unique PSC number (Primary Scrambling Code, a total of 512 different PSCs), so they cannot be used for positioning.

It is also worth noting that netmonitors, in particular G-Mon, also record these parameters:

Parameter	Format	Description
RNC ID	16-bit integer	Radio Network Controller Identifier, Radio Network Controller ID. A radio network controller is needed to manage a group of NodeB base stations; its number is unique within the operator’s network.
C-ID	16-bit integer	Cell Identity, Cell ID. Represents a physical sector identifier unique to each RNC. Used in the composition UC-ID(see below).
UC-ID	RNC ID + C-ID	UTRAN Cell Identity, UTRAN Cell ID 1. Unique identifier of a physical cell in the operator’s network. Used to identify sectors in the NodeB to RNC and RNC to each other communication interfaces.

UTRAN - Universal Terrestrial Radio Access Network, the name of the UMTS data transmission network.
It should be noted that instead of UC-ID, G-Mon displays a parameter called LCID and defined as RNC ID + SAC. This so-called LCID is not used for user equipment positioning. This UC-ID is also not used by user equipment and is needed for the correct functioning of the core network (CN, Core Network).

LTE

LTE, Long-Term Evolution- Fourth generation mobile network, literally translated: Long-term development (strictly speaking, LTE is still the third generation of communications, and is designated as 3G LTE, i.e. Long-term development of third generation networks. Only LTE Advanced networks can rightfully be called the fourth generation ). LTE networks can be deployed in 44 frequency bands (at the same time, in bands 33-44, time division of channels (TDD, Time Division Duplex) is used, i.e. reception and transmission occur in the same band, but not simultaneously). In Ukraine, it has long been said that LTE technology attracts operators. But it is not yet known when it can be introduced in our country. The following ranges are used in Russia:

Number	Range name	Transmission range, MHz	Reception range, MHz
7	2600	2500-2570	2620-2690
20	800	832-862	791-821
38	TDD 2600	2570-2620
40	TDD 2300	2300-2400

If we talk about the parameters that define a cell in LTE networks, then everything is somewhat different here. We will need the PLMN ID (MCC and MNC), as well as the following parameters:

eNodeB- Analogue of a base station in LTE. In GSM it is called BTS, and in UMTS NodeB.
E-UTRAN- Evolved Universal Terrestrial Radio Access Network, the name of the data transmission interface of the LTE network.

The cell here is uniquely identified by a combination of MCC-MNC-ECI parameters (PLMN ID-ECI). As you can see, there is no LAC provided in LTE networks. This is due to the fact that the data transmission network in LTE is extremely simplified and consists only of a network of base stations (eNodeB) and a dedicated packet data core. There are no switches (MSC, Mobile Switching Center), base station controllers (BSC, Base Station Controller) or radio network controllers (RNC, Radio Network Controller), and their functions are assigned to interconnected eNodeB base stations. However, an analogue of LAC in the LTE network also exists - this is TAC. However, it no longer participates in the hierarchical numbering of cells (moreover, cells at the same base station may have different TAC) and is needed for correct tracking of the location of user equipment (UE, User Equipment - analogue of MS from GSM) - when the UE moves to another tracking area , the Tracking Area Update procedure occurs. TAC in LTE networks serves to logically divide the network into tracking zones, unlike LAC, which is rather a physical division of the network.

Netmonitor is
additional phone menu. First of all
it is intended for specialists
test checks of base stations (BS) operation
specific GSM operators, as well as for
tracking their location, condition,
operating mode, signal level, coverage, etc.
Attention: I immediately warn you that this
operation may impair performance
apparatus; everything will be fine if you follow
all the rules.

In this article I will tell you how
you can deceive BS using Netmonitor,
more specifically, tie the handset to the BS,
located at the other end of the city, and not on
the closest one. If you're willing to take risks
and you are interested in this, then let's get started.

You will need a PC and a mobile phone
phone: Nokia3310, 5210, 8210, (I don’t know about the others
aware), as well as an additional accessory
for telephone + PC communication. For 3310 you will need
cord, the rest are equipped with infrared,
accordingly, the infrared port should be for
computer. First of all, we find
the wonderful program Logomanager (in my case
There was a first version with a crack). She weighs
only 450 kilos in a zipper.

Connect your mobile phone to your computer and
launch the unzipped program. Further
go to Tools => NetWork Monitor and all the values ​​according to
we roll up the queues on the mobile, not forgetting
pass through Field Test, then OK. All
values ​​are rolled up separately.
Having finished dirtying the mouse, on the phone display
you can see the Additional NetMonitor Menu,
some is Menu-^.

Let's move on: In the 33rd cell of the SIM card
(not phone number) we write: BESTTEST xxxx, where
xxxx tower number (BS). As a number
phone number we register the same number
towers xxxx, Save. Checking: in mode
waiting, dial 33#, The result should be
before your eyes, i.e. BESTTEST xxxx. We go out and climb into

Reboot the mobile.

So, half the battle is done. Now
I’ll tell you what points 1,3,4,5,17 mean

many BS-ki are duplicated, then let's take to
example, tower numbers from 101 to 120 (for Megafon-Moscow),
They are the ones that are duplicated most often.

And if you managed to remember the number
tower located at the 1st point, then we do
the following: in the 33rd cell of the SIM we find BESTTEST xxxx,
edit, instead of xxxx we write the number
towers (remembered by you or, as I said,
we will guess from 101 to 120). Now let's save
remade, go to Netmonitor, 17-OK,
if it lights up ‘Off’, we go out and climb again:
netmonitor, 17-OK, must be observed Requested,
Here we reboot the mobile. After
When turned on, the message “ON” should appear.

If so, then keep it
Congratulations, if not, try it
try your luck with the number of another tower.
If the attempt is successful, the phone should receive
network from the BS we registered on, so
that the mobile phone can catch the network very poorly
if you registered on a tower that can
be 2-3 km from you, and if they light up
all the "sausages", then you are on one of the most
nearest.

We learned to jump, but only
to neighboring towers, now I’ll tell you which ones
they exist and how to find them. As it was
as stated above, many towers are duplicated and

suppose to the other end of the city, then
you will have to purchase additional
equipment for the phone: directional GSM antenna
and a 12 volt car booster,
climb as high as possible (preference
given to those living on the 9th and above floors),
put it all together as it should be
follow the attached instructions and go ahead.

I warn you, the more expensive
kit, the further you jump, the more
chances of ruining your mobile (well, if you
really going to jump over 100 seconds
extra km), telephone hardware may not
withstand. All that's left is to ride around

where there may be 10,000 people, they
let them suffer, why can't they
call, and then jumped to more
free BS and constant beeps and interruptions
communications will not be disturbed.

P.S. To prevent the NetMonitor menu from interfering with
desktop, in the test menu type 0-OK.
To make NetMonitor disappear from your phone,
you need to dial 497-OK. Loaded menu
The netmonitor takes up 8kb of phone memory.

Description of the Autostart And StaY program:

The program "Autostart And StaY" is a manager for autostart applications on the phone. The main function of the program is to block startup applications. However, for netmonitoring, the option of setting any third-party application to autorun is more useful.

Install the application, select “Netmonitor by parizene” from the list, check the “Autostart (autostart after switching on)” and “Stay (keep the application running)” checkboxes, start the algorithm by clicking on “Service Toggle”.

After restarting the device, "Netmonitor" will automatically start and log recording will begin. Even if for some reason the work of "Netmonitor" is completed, the application will start again.

NetMonitor technological software allows you to:

• Configure the Mercury 225.2 and 21 concentrator
• view and configure PLC II network structure
• receive data from meters and transmit control commands

To communicate with the hub, you must specify in the program:

• number of the virtual COM port created by the system. (The COM port number can be found using the "Device Manager.");
• information exchange speed (default speed is 38400);
• network address of the hub.

The network address of the hub is either indicated on a sticker on the device body, or can be read using the address determination function in the NetMonitor program. To use this function, while holding down the CTRL key, you must click on the button "Enter" located in the upper right corner of the program window, to the right of the network address entry fields. Only one hub must be connected to the computer.
The program has three fields for entering a network address for simultaneous work with three hubs, but such simultaneous work is only possible when polling hubs via the RS-485 port, but not via USB.

After setting all of the above parameters, you need to click the button "Enter". If the connection is successful, in the lower left corner of the window the counter will begin counting the bytes received from the device. A message will appear to the right: "Communication port is open"

The system structure will be displayed in the central part of the window.

The purple rectangle represents the entire PLC II network as a whole. Orange - concentrators operating in the system. Yellow - counters. Devices with which communication has been lost are marked in gray.

Setting the window view.

Right-clicking on the empty space of the central window brings up a context menu for view settings.

Compact network view allows you to display counter icons in either a compact or expanded form.

In the expanded view, the counter icon displays a number of informers, the description of which is contained in the legend. The legend is displayed using the following context menu item "Show legend"

Group configuration of hubs

Basic operations in the program are performed using the context menu, i.e. menu called up by right-clicking on an object.
The "PLC-NET" rectangle in its context menu contains some group commands and commands for working with the network as a whole.

Menu item "PLC network tasks", allows you to configure group hubs and set their operating mode.

Three modes are possible:

IDLE- the hub is inactive
MASTER- main operating mode, the hub performs scanning functions, polling meters and checking communications.
SLAVE- the hub performs the function of a repeater; it does not perform polling, scanning or checking functions.

Operating mode "ABC" allows you to use one concentrator to operate in three phases. If three hubs are used, then this mode must be disabled .

Select the required operating mode and click on the “Apply” button. The mode will then be installed in all hubs displayed in the structure.

Menu item "Register a new node" designed to force counters to be added to the network structure.

Paragraph "Simple list of nodes" allows you to save or load a list of detected and (or) added counters from a text file.

Paragraph "Task file for BQuark" allows you to automatically generate a task file for the BQuark program.

, "Clear requests" Accordingly, all counters are removed from the network structure and all requests performed by the hubs are erased.
Concentrators collect data from meters in accordance with the built-in polling program. The polling program consists of separate commands (queries), each of which is designed to obtain a specific parameter from the counter. Clear previously recorded queries and allows the corresponding menu item.

Individual work with the concentrator.

Individual settings are made through the context menu, called up by right-clicking on the hub icon.

From this menu you can set one of the functional operating modes, MASTER, SLAVE or IDLE.

Menu item "Tasks" duplicates the corresponding item from the PLC-NET menu, with the difference that the settings made using this menu apply only to a specific hub.

Menu item "Tools" opens a corresponding window with the option to:

• Read or change the network address of the hub (UART-ID)
• Read the current firmware version number, and also reflash the hub,
• Read and set the number of mailbox segments
• Read and change the speed of information exchange via the RS-485 port and USB hub
• Read and set the date/time on the hub's internal clock
• Correct the speed of the hub's internal clock

Netmonitor is
additional phone menu. First of all
it is intended for specialists
test checks of base stations (BS) operation
specific GSM operators, as well as for
tracking their location, condition,
operating mode, signal level, coverage, etc.
Attention: I immediately warn you that this
operation may impair performance
apparatus; everything will be fine if you follow
all the rules.

In this article I will tell you how
you can deceive BS using Netmonitor,
more specifically, tie the handset to the BS,
located at the other end of the city, and not on
the closest one. If you're willing to take risks
and you are interested in this, then let's get started.

You will need a PC and a mobile phone
phone: Nokia3310, 5210, 8210, (I don’t know about the others
aware), as well as an additional accessory
for telephone + PC communication. For 3310 you will need
cord, the rest are equipped with infrared,
accordingly, the infrared port should be for
computer. First of all, we find
the wonderful program Logomanager (in my case
There was a first version with a crack). She weighs
only 450 kilos in a zipper.

Connect your mobile phone to your computer and
launch the unzipped program. Further
go to Tools => NetWork Monitor and all the values ​​according to
we roll up the queues on the mobile, not forgetting
pass through Field Test, then OK. All
values ​​are rolled up separately.
Having finished dirtying the mouse, on the phone display
you can see the Additional NetMonitor Menu,
some is Menu-^.

Let's move on: In the 33rd cell of the SIM card
(not phone number) we write: BESTTEST xxxx, where
xxxx tower number (BS). As a number
phone number we register the same number
towers xxxx, Save. Checking: in mode
waiting, dial 33#, The result should be
before your eyes, i.e. BESTTEST xxxx. We go out and climb into
Netmonitor icon, in the input field we type 17, OK.
Reboot the mobile.

So, half the battle is done. Now
I’ll tell you what points 1,3,4,5,17 mean
no monitor. The 1st shows the tower number and its
data on which you are currently registered
telephone. 3,4,5th show the nearest BS-ki, 5th
the menu may not be completely full,
we do a scan: without leaving the 5th
point, dial any phone number,
We call and hang up right away. Scanned
2 more lines, i.e. 2 more BS's. With this a little
We figured it out, point 17 is the most important
for us, it is through him that we will
do all the tricks. You most likely have
it says off or requested and note that your
The mobile phone may not be able to connect to the network for this
moment, this is normal, because... we tried
register on an unknown tower. And since
many BS-ki are duplicated, then let's take to
example, tower numbers from 101 to 120 (for Megafon-Moscow),
They are the ones that are duplicated most often.

And if you managed to remember the number
tower located at the 1st point, then we do
the following: in the 33rd cell of the SIM we find BESTTEST xxxx,
edit, instead of xxxx we write the number
towers (remembered by you or, as I said,
we will guess from 101 to 120). Now let's save
remade, go to Netmonitor, 17-OK,
if “Off” lights up, we go out and climb again:
netmonitor, 17-OK, must be observed Requested,
Here we reboot the mobile. After
When turned on, the message “ON” should appear.

If so, then keep it
Congratulations, if not, try it
try your luck with the number of another tower.
If the attempt is successful, the phone should receive
network from the BS we registered on, so
that the mobile phone can catch the network very poorly
if you registered on a tower that can
be 2-3 km from you, and if they light up
all the "sausages", then you are on one of the most
nearest.

We learned to jump, but only
to neighboring towers, now I’ll tell you which ones
they exist and how to find them. As it was
as stated above, many towers are duplicated and
You can watch them in menus 1.3-5

experiment, did it work? Yes, but
not far, you jumped at a distance of about 3000m
from your location. Check it out
you can from another phone using new ones
location services,
such as AOP, WebLocator-Lite, SMS games BotFighters and
etc. 3km is the maximum distance
phone number to BS, which can help you
serve. If you want to jump further,
suppose to the other end of the city, then
you will have to purchase additional
equipment for the phone: directional GSM antenna
and a 12 volt car booster,
climb as high as possible (preference
given to those living on the 9th and above floors),
put it all together as it should be
follow the attached instructions and go ahead.

I warn you, the more expensive
kit, the further you jump, the more
chances of ruining your mobile (well, if you
really going to jump over 100 seconds
extra km), telephone hardware may not
withstand. All that's left is to ride around
city ​​and mark them on the map
location.

Note...

This article will be useful
for example, in crowded places
people, for example, a major football match,
where there may be 10,000 people, they
let them suffer, why can't they
call, and then jumped to more
free BS and constant beeps and interruptions
communications will not be disturbed.

P.S. To prevent the NetMonitor menu from interfering with
desktop, in the test menu type 0-OK.
To make NetMonitor disappear from your phone,
you need to dial 497-OK. Loaded menu
The netmonitor takes up 8kb of phone memory.
The operation was carried out in the Moscow Region
on Nokia5210 handset with firmware v5.25 and
