Hi,
Is there a function in OpenBSC that can help in estimating the diastase of the connected
phone ? For example, something that gives the value of the power received by the phone
from the BTS and the power received by the BTS from the phone (during paging or active
call).
best regards,
Hi sami. You can see those uplink and downlink power levels with
'show
lchan' in OpenBSC.
For example:
Measurement Report:
Flags:
L1 MS Power: 33 dBm, Timing Advance: 9
RXL-FULL-dl: -86 dBm, RXL-SUB-dl: -87 dBm RXQ-FULL-dl: 0,
RXQ-SUB-dl: 0
RXL-FULL-ul: -87 dBm, RXL-SUB-ul: -47 dBm RXQ-FULL-ul: 0,
RXQ-SUB-ul: 0
There you will also see "Timing Advance" although I'm not sure how
exactly to interpret that. Maybe somebody else might comment. I'm also
not sure what RXQ is, although I've seen those numbers increase when I
use very low power levels in osmotrx and move the MS away from the USRP,
so I presume it's an indicator of RF errors?
I'll take the opportunity to also ask for clarification on that :)
