Hi Jon,
The "show cellular 0 radio" command will give you the dBm information.
See the below output for the same.
#sh cellular 0 radio
Current Band = WCDMA 2100, Channel Number = 10836
Current RSSI(RSCP) = -89 dBm
Band Selected = Auto
Number of nearby cells = 1
Cell 1
Primary Scrambling Code = 0x15B
RSCP = -89 dBm, ECIO = -10 dBm
Hope the above will help you.
Please click on the correct answer if thi answered you.
Regards,
Naidu.
