Hi all,
Please, can any one give me some advise on how to solve drop call on long road coverage sites?
Drop calls are mainly caused by low ss in both link and go up to TA 85.
Extended range is already activated.
I don't want to lose traffic ( coverage) but I wanna solve drop calls.

Thanks for your help!

you might consider change antena to narrower beam-widt antena with highers gain, over 20dB (increase your DL SS) and use of TMA (increase UL SS)

Also you may consider space diversity solution for UL drop also ; antenna hopping will help as well (AHOP feature )

Try increasing RLT and SAMUL. Put up a High Gain Antenna with 24 or 21 dBi and a TMA to increase uplink.
