We have a high WCDMA cs drop, on some cells that have a high level of uplink interference. Hardware is ok, what could be a problem?
check the RTWP, if higher than -95dBm, investigate for external interferences!
Hi Erick,
There are many reason for WCDMA cs drop:
1.Due to weak coverage
2.Due to interference.
3.Due to intigrity check
4.During ciphering procedure
5.Problem with Iu and Iur interface in network( RRC and RAB cs voice drop)
