Tracks
Information about network, for aech cell are available several calues. For actual cell are shown all values, for next 6 with best signal only ARF, BSI, RXL, C1 and C2 and for remaining only BSI and RXL.
ARF
Active channel number (GSM 900MHz between 0001-0124, GSM 1800MHz between 0512-0885).
BSI
Base Station Identity Code. This 6bit number contains two 3bit parts - Base-station Color Code (BCC) and National Color Code (NCC). BCC distinguishes cells of one operator with same ARF and NCC separates cells into regions.
RSS
Recieved Signal Strength Indicator. After conversion into decimal system, dividing by 2 and multiply by -1 this shows value in dBm.
RXL
Received Level. Displays same as RSS, only converted into format used in GSM specification:
|
0
|
