Hi All,
Can anybody help with information about following issues:
1) From which point it taken/measured RSSI reported by UMTS cell?
2) How much have to be the range (for correctly configured track) of UL levels(noise floor) measured at the end of feeder connector before the top of the cabinet. If for example the levels are -110, -112 is that enough for normal working of the cell in UL.
In case we have co-site u900 combined with GSM900 and there is installed TMA(for the needs of u900) what have to be the shape of the measured spectral diagram - even or with increased levels in U900 band.
Thank you!
