Netmonitor (GSM)
This is a program for monitoring the GSM-network mobile
operator.
Main Window


The main window shows basic information about the network:
- Operator (consists of MCC (country
code), MNC (network code) and name)
- Сonnection type (GPRS, EDGE, UMTS,
etc., if the phone is not connected to the network, then UNKNOWN)
- LAC (Local Area Code)
- CID (Cell Id)
- PSC (available in the 3G networks)
- Signal Level (varies
in the range from -113 to -51 dBm)
- Information about cell (if available in the database,
otherwise no info)
- A list of neighboring cells (maximum 6).
This list is not available on some phones (Samsung, Acer, Huawei),
as well as in 3G networks (only PSC, can be enabled in settings). List item includes: LAC, CID, signal strength and
information about cell
Log window

Log window shows a list of cells which were current or neighbors.
List item includes:
- Status
Icon (if
,
then the cell was current, if
,
this cell was only the
neighboring)
- LAC
- CID
- PSC (if cell is 3G)
- Operator (MCC + MNC), can be enabled in settings
- Icon of the presence of the
cell coordinates in the
program (no coordinates -
, from
imported database -
, from Gears
Geolocation API -
)
- Time of the last registration of the cell
- Information about cell (if available in the database,
otherwise no info)
Clicking on the item in the list, you can open a window to edit information
about the cell, the changes will be stored in the database. Then, with the
subsequent registration of cells, information about it will be retrieved from
the database.
Map Window

If Internet is enabled in the settings and there are cells coordinates in the
log window, the cell will be displayed on the map. CID of the current cell is
displayed in the green rectangle, of the neighboring
- yellow, cells, which were previously current or
neighbors - red. Clicking on the cell site, more
complete information will be showed.
Settings
- Choose a theme (available light and dark). Theme apply requires the
closure of the program
- CID display mode (divide the number and cell sector)
- Show neighborings in 3G
mode, only PSC and signal strength
- Show operator (MCC + MNC) in log window
- Show date in log window
- Ignore LAC, while getting info from database, will marked as *:
- Type of file to import the database of cells
- Type of log to write to a file (not recorded in the log file, save only
the switching cells or a permanent record of information about cells)
- A possibility not to clear log window on program start
- The path to the program folder on the memory card from which to import
an input file that will create the database, and where to write to a log
file. The standard path is data/netmonitor, if the path is left blank,
then the program folder is the root of the memory card
- Whether to use the Internet, which is used to display
maps and download coordinates from the Gears
Geolocation API (if no cells coordinates in a
program database)
- Save cells coordinates obtained from the Gears Geolocation API, for
further use (so that the next time they do not optained from the network)
Import Database Types
The program contains a SQLite database to store information about cells, its
coordinates. Supports 3 types of input files to import:
- Default
- Clf v2.0
- Clf v3.0
All files must be encoded UTF-8. File type to import you can change in
settings. The file name should consist of the MCC (3 digits) and MNC (2 or 3
digits) and have the extension .clf (for example, 25704.clf for life:) BY).
1. Default
Data format:
MCC;MNC;LAC;CID;LAT;LON;INFO
Note. LAC and CID are decimal. Lat - latitude, Lon - longitude, Info
- information about cell, which will appear in the program. Example file for
import:
257;04;1000;10356;45,345645;-34,456;info about cell
2. Clf v2.0
Data format:
CID + LAC + MCC + MNC <tab>
INFO
Note. LAC (4 digits) and CID (4 digits) in hexadecimal. Info -
information about cell, which will appear in the program. Example file for
import:
287403E825704 info about cell
3. Clf v3.0
Data format:
MCC + MNC;CID;LAC;RNC;LAT;LON;RAT;INFO;RFU
Note. LAC (0x + 4 digits) and CID (0x + 4 digits) in hexadecimal.
Lat - latitude, Lon - longitude, Info - information about cell, which will
appear in the program. Rnc (0x + 4 digits, hex), Rat (dec), Rfu (dec) is not
used, must be equal to 0. Example file for import:
25704;0x2874;0x03E8;0x0000;0;0;0;info about cell;0
Prepared files for import clf v2.0 and v3.0
