We have observed major RSSI impact in TDD sectors in Ericsson-Bharti(Airtel) networks, Few troubleshoot has bee done but not able crack. Kindly help me out in this situation.
Activity done : GPS change,Checking TDD locked in neighboring site, hardware checked,cable connector checked.etc.
Eqipment-Ericsson. Also no external interference found.
Same issue is been observed in the network I am working currently,i could be because of Tropospheric ducting due that TDD signal can travel long distance.majorly in this case DL travelled signal is interfere with uppts.u can check symbol level RSSI if rssi of symbol 1st n last symbol is differ more than 1db then this could be the same issue.
