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

In this article, I will show you how
you can fool the BS-ku using the Netmonitor,
more specifically, then tie the handset to the BS,
located on the other side of the city, and not on
the nearest one. If you're willing to take the risk
And if you're interested, let's get started.

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

Connect mobile phone to computer
run the unzipped program. Further
we climb into Tools => NetWork Monitor and all the values by
we roll the queues into the mobile, not forgetting
pass through Field Test, then OK. All
values are rolled up individually.
Having finished dirtying the mouse, on the phone display
you can see the NetMonitor Additional Menu,
something is Menu-^.

Going further: In the 33rd cell of the SIM card
(and not the phone) we prescribe: BESTTEST xxxx, where
xxxx tower number (BS). as a number
phone, write the same number
towers xxxx, save. We check: in the mode
waiting dial 33#, The result should be
before the eyes, i.e. BEST TEST xxxx. We go out, we climb into
Netmonitor icon, type 17 in the input field, OK.
We reboot the mobile.

So, half the work is done. Now
I will tell you what points 1,3,4,5,17 mean
nomonitor. 1st shows the number of the tower and its
the data on which you are currently registered
telephone. 3,4,5th show the nearest BS, 5th
the menu may not be fully loaded,
do a scan: without leaving the 5th
point we dial any phone number,
call and hang up immediately. scanned
2 more lines, i.e. 2 more BSs. With this a little
figured out, point 17 is the most important
for us, it is through him that we will
do all tricks. You most likely have
it says off or requested and note that your
mobile may not catch the network for this
moment, this is normal, because we tried
register on an unknown tower. And since
many BSs are duplicated, then we take to
example tower numbers from 101 to 120 (for Megafon-Moscow),
These are the ones that are most often duplicated.

And if you managed to remember the number
tower located in the 1st point, then we do
the following: in the 33rd cell of the SIM we find BESTTEST xxxx,
edit, instead of xxxx we prescribe a number
towers (remembered by you or, as I said,
We will guess from 101 to 120). Now save
reworked, we climb into the Netmonitor, 17-OK,
if "Off" is lit, Exit, climb again:
netmonitor, 17-OK, should be observed Requested,
here we restart the mobile. After
turn on, "ON" should appear.

If so, then keep
Congratulations, if not, then try
try your luck with the number of another tower.
With a successful attempt, the phone should catch
network from the BS on which we registered, so
that the mobile phone can catch the network very badly
if you registered on the tower, which can
be 2-3 km away from you, and if they glow
all "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
mentioned above, many towers are duplicated and
you can watch them in 1.3-5x menus
nomonitor. Try with them
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
location services,
such as AOP, WebLocator-Lite, BotFighters SMS games and
etc. 3km is the maximum distance
phone to the BS-ki, which can you
serve. If you want to jump further
suppose to the other end of the city, then
will have to purchase additional
ammunition for the phone: a directional GSM antenna
and a 12 volt car booster,
climb as high as possible (preference
given to those living on the 9th and higher floors),
put it all together in the right way
attached instructions and go ahead.

I warn you, the more expensive
set, the further jump, the more
chances of ruining your mobile (well, if you
really going to jump for 100 s
extra km), the phone stuffing may not
endure. It remains to ride on
the city and mark them on the map
location.

For example, in crowded places
people, for example, a major football match,
where there can be from 10,000 people to the people, they
let them suffer, why can't they
call, and then jumped over to more
free BS-ku and constant beeps and breaks
connections will not bother.

netmonitor(English) Net Monitor, field test, Channel info) is a cell phone function that allows you to display various technical parameters of networks cellular communication. Usually, the non-monitor functions also include displaying various service information of the phone itself (phone temperature, exact battery charge level), but this data is not strictly non-monitor information. In our video, we use the netmonitor in the iPhone, see.

Most often, ordinary subscribers do not need these parameters. Cellular manufacturers do this function either in order to be able to test the correct operation of the phone itself, or for cellular network workers (although specialists often purchase specialized measuring systems, for example, TEMS from Sony-Ericsson).

However, the netmonitor has found application in an interesting and exciting activity - netmonitoring.

Netmonitor in various phone models

Depending on brands and models cell phones Turning on a netmonitor can be both simple and complex. For example, a number of phones (Siemens 65 series and higher, Nokia DCT-4 and higher up to Series 60, some models of SonyEricsson and Samsung) do not allow this function to be enabled without changing the firmware or entering service data into system areas memory. At the same time, most old and a number of modern phones allow you to enable this function by entering a special code that is different for different manufacturers and even models.

When choosing a mobile phone purely for non-monitoring, both ease of inclusion and data format must be considered. The most understandable for perception is the netmonitor Alcatel phones(having a single entry code in engineering menu- 000000*, except for the Alcatel OT 320 ODM model, where the netmonitor code is *#3646633#, after entering which the netmonitor can be called by *0# until the phone is restarted), LG (the most popular codes are 2945#*1#, *#3646633#), Siemens, Motorola (known codes ***113*1*, *#307#, 00**83786633*), Philips (*#2355*#), Trium and Bosch. For some Samsung phones suitable code *#0206*324#, *#8999*324# for SonyEricsson platform DB2010 and earlier - *585*0000#.

For smartphones and PDAs, there is a special software for netmonitoring that does not require any changes in the firmware.

How is it done withiPhone ( for 900 and 1800 MHz networks).

Menu navigation:

GSM Cell Environment -> GSM Sell Info -> GSM Serving Net -> look at the ARFCN value.

How is it done withiPhone (for 3G networks).

To get into the netmonitor menu, dial *3001#12345#* on the iphone and the call button (green tube).

According to the menu structure below, we find the Downlink Frequency item, offered in the UARFCN format.

UARFCN – UTRA Absolute Radio Frequency Channel Number ( The conditional number of the frequency radio channel in the UMTS system, which determines the value of the carrier frequency of the radio channel). Displayed in iPhone we divide the value of Downlink Frequency UARFCN by 5, and according to the table below we find the range of our network, on the left, respectively, the communication standard.

Please note that the phone automatically selects the most capacious standard, therefore, even if the phone operates on the 2100 MHz standard, this does not mean that there is no operator signal in the 900 MHz standard in the area where the repeater is installed. The 900 MHz standard is recommended for remote and weak signal areas, as it has the least attenuation. That is why 900 MHz repeaters are the most in demand and popular on the market.

Based on materials from open sources on the Internet and the free encyclopedia Wikipedia.

Network monitoring (network monitoring): Search for base stations of cellular operators and record their technical parameters. It exists in the form of a hobby, similar to the pleasures of fox hunting or geocaching. The programs used for searching are known mainly as Netmonitor. The purpose of network monitoring is to create and maintain a database of information about the BS of cellular operators in the state of the database record.

For getting detailed information special engineering devices are used, as well as in the economic version of the application for a mobile phone, for example, NetMonitor for Android, which will now be parsed.

And so, we list the main characteristics of the monitoring program:

monitor signal and service levels cellular networks second, third and fourth generations;
Ability to report log data received in the program;
development of a mapping network and signal levels on Google maps;
Export sessions to CSV and KML;
export of cartographic data to KML;
view statistics for certain data;
Download and Paste external file BTS with extra cell data
Widget 2x1 and 4x2;
user management;
The program is absolutely free and does not mind intrusive ads.

Screenshots of NetMonitor for Android

Netmonitor is a tool for displaying technical data on the state of the network of a cellular operator. Allows you to determine the level of the incoming signal of the operator and the number of channels on which this operator works, the type of network and basic parameters.

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

Basically, this information is used for proper 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. The signal level is visible in the upper left corner mobile operator, reflected in dB. Next, go to the GSM Cell Environment / GSM Cell / Neighboring Cells tab, here you can see the list of channels. There are 6 channels in total. 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 of 1-124 or 974-1024 means that the operator operates in the 900 MHz band and we need (900 MHz) or a GSM900 repeater.

An ARFCN value in the range 512-886 means that the operator operates in the 1800 MHz band and we select the 1800 antenna or the 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 a GSM900 Repeater.

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

We advise you to watch information on several channels. Also information on this definition channel numbers will be more reliable if these measurements are taken while connecting with another subscriber (incoming or outgoing call). It must be understood that the phone shows all the 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 under 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 based on the Android OS is suitable for installing programs (well, or almost any, we do not recommend using Chinese iPhones on Android). Nexus series devices performed well (primarily due to latest version Android OS) and HTC Desire- netmonitors on these devices, they show the maximum possible information. Other makes and models of devices will also work, but may not display some Additional information(for example, a list of neighboring base stations, as 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 so many of them, but 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 human-readable machine-readable log, along with GPS coordinates in some cases.

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

What to monitor?
To begin with, let's define the task - we need parameters that uniquely determine the base station, or rather, a specific sector (cell) of the base station or another minimum 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 GSM network has the following parameters:

Parameter	Format	Description
MCC	3 decimal digits	Mobile Country Code, Code of the country. Country unique identifier ( full list MCC).
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 an 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 non-monitors it can be referred to simply as a network (net).
LAC	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.
TA	6-bit integer (0 to 63)	Timing Advance, Time advance, Timing Ahead. The indicator of the time delay of the signal. Increases by 1 with increasing distance from the base station 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 for unambiguous determination of a cell in the world. And it is these parameters that any netmonitor shows us.

If the netmonitor shows the TA parameter, then you can approximately (with a gradation of 550 m) set the distance of the mobile station from the base station. For positioning, this can be useful 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 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 configuring the network parameters and serves to correctly carry out the procedure for the MS transition from one cell to another (such a transition is called a 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, of which two are used in Ukraine:

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

In UMTS networks, such a concept as Cell (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) at the same time (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 connect to three physical cells at the same time, which helps to ensure the so-called. seamless or soft transmission (softer handover, soft handover), without breaking and recreating the channel.

The mapping of service areas and cells is transparent, i.e. imperceptible to the data network and, accordingly, to non-monitors.

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

For non-monitoring, the difference is only in the name - CID has changed to SAC, other parameters have remained the same, and the unique cell number (in this case, the service area) has the following form: MCC-MNC-LAC-SAC.

Non-monitors usually make no distinction 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 the Neighboring Set. However, neighboring cells here are just physical cells, each of which is determined by a non-unique PSC number (Primary Scrambling Code, 512 different PSCs in total), so it will not work to use them for positioning.

It is also worth noting that non-monitors, in particular G-Mon, also fix these parameters:

Parameter	Format	Description
RNC ID	16-bit integer	Radio Network Controller Identifier, Radio Network Controller ID. The 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 unique physical sector identifier for 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 NodeB to RNC and RNC to each other communication interfaces.

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

LTE

LTE, Long-Term Evolution- Mobile network of the fourth generation, literally translated: Long-term development (strictly speaking, LTE is still the third generation of communication, and is designated as 3G LTE, i.e. Long-term development of third-generation networks. Only LTE Advanced networks can rightly 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. In Russia, the following ranges are used:

Number	Range name	Transmission range, MHz	Receive 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 a PLMN ID (MCC and MNC), as well as the following parameters:

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

The cell here is uniquely identified by a bunch of MCC-MNC-ECI parameters (PLMN ID-ECI). As you can see, no LAC is 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) here, 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 can have different TAC) and is needed to correctly track the location of user equipment (UE, User Equipment - an analogue of MS from GSM) - when the UE moves to another tracking area , the Tracking Area Update procedure is in progress. TAC in LTE networks serves to logically divide the network into tracking areas, in contrast to LAC, which is rather due to the physical division of the network.

Netmonitor is

Description of the program Autostart And StaY:

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

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

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

Technological software NetMonitor allows you to:

carry out the configuration of the concentrator Mercury 225.2 and 21
view and configure the PLC II network structure
receive data from meters and transmit control commands

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

virtual number COM port generated by the system. (The COM port number can be found using the "Device Manager".);
information exchange rate (by default, the rate is 38400);
network address concentrator.

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

After setting all the above parameters, you must click the button "Input". In case of successful communication, the counter in the lower left corner of the window will start counting the bytes received from the device. To the right, a message will appear: "Communication port is open"

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

The purple rectangle indicates the entire PLC II network as a whole. Orange - hubs operating in the system. Yellow - counters. Devices with which communication is lost are marked in gray.

Window view setting.

Cry right button mouse over the empty space of the central window, calls the context menu for setting the view.

Compact representation of the network allows you to display counter icons either in 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 by the following item context menu "Show legend"

Bulk configuration of hubs

The main operations in the program are performed using the context menu, i.e. menu called by clicking the right mouse button on the object.
The "PLC-NET" rectangle in its context menu contains some group commands and networking teams in general.

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

Three modes are possible:

IDLE- the hub is idle
MASTER- the main mode of operation, the concentrator performs the function of scanning, polling counters and checking communication.
SLAVE- the concentrator performs the function of a repeater; it does not perform polling, scanning and verification functions.

Working mode "abc" allows you to use one concentrator for three phases. If three hubs are used, then this mode should be disabled .

Select the desired mode of operation and click on the "Apply" button. The mode, after that, will be set in all hubs displayed in the structure.

Menu item "Register new node" is designed to force the addition of meters 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 "Job file for BQuark" allows you to automatically generate a job file for the BQuark program.

, "Clear Requests" respectively remove all counters from the network structure and erase all requests performed by the concentrators.
Concentrators collect data from meters in accordance with the embedded polling program. The polling program consists of separate commands (requests), each of which is designed to receive a specific parameter from the counter. Clear previously recorded requests and allows the corresponding menu item.

Individual work with a concentrator.

Individual settings are made using the context menu called 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 the corresponding window with the ability to:

Read or change the network address of a hub (UART ID)
Read the number of the current firmware version, as well as flash the hub,
Read and set the number of mailbox segments
Read and change the communication speed of the RS-485 port and USB hub
Read and set the date/time on the hub's internal clock
Make a correction of the course of the internal clock of the concentrator

The functionality of the buttons in this window changes when you press the CTRL keys on the PC keyboard.

Menu item " Connect new node", "Delete all slave nodes" repeat the functions of "Register new node" and "Delete all slave nodes" in the PLC-NET menu.

Menu item "A simple list of nodes..." allows you to save the list of counters found during scanning as a list, as well as upload a previously created list to the concentrator.
