5. Cell Scanner

Cell Scanner is a utility inside the NG-Scope framework that scans for cells around you and produces a list of the detected cells and some parameters that might be relevant such as EARFCN, band or cell ID.

Cell Scanner gets compiled automatically with NG-Scope. After compiling it, you can find it under build/cellscanner/source/. It takes two mandatory arguments and one optional:

./cellscanner <Output file> <Region ID> <USRP arguments (optional)>

output file: path to the CSV output file. That file will contain the scanned cells.

Region ID: The Region ID tells cellinspector what bands should be scanned. 0 is for all bands, 1 is for USA bands, and 2 is for Europe bands.

USRP arguments: This optional parameter is used in case you want to pass some parameters to the USRP (e.g. you can pass "serial=SERIAL_NUMBER" in case you have multiple USRPs connected to the system and you want to use the USRP with serial number SERIAL_NUMBER).

The output file contains the following self-explanatory columns: **band,cell_id,dl_earfcn,freq_mhz,prbs,pss_power_dbm **. Here you have an example recorded at Princeton:
