VOLTE Mute call Increased in our NW Post Carrier BW Change from 5Mhz to 10 Mhz. i have done the sample checks and found that Cells which are having High Mute call are radiating with 12.2 dbm (40 W RRU) RS Power while Previously they were radiating with 15.2 dbm (80 W RRU) RS power . there is no impact on cells where RS Power is same as Before i.e 15.2 dbm.
Now there is no option to change Power on Cells which are radiating with 12.2 dbm due to RRU Power Limitation(40 W). I am Uptilting the antenna as an interim measure to compensate the coverage loss… But what Other Parameter i can look into to Improve Mute calls.
