Dear All.i have same question about NSN BTSs.we activated AHOP in ultrasites,Flexi BTSs,MBBs ,but without any improvement in term of Rx-qual uplink and downlink.we just enable that at cell level with AHOP=Y,but i think that it must have requirements in BTS also(such as cabling,antenna type,combiner,....)can u guide me to correctly activate this amazing feature.just note that we activate this feature in siemens BSC(BR8) and get big improvement in all KPIs.thanks

I make search about this and I found Antenna hopping is not possible, either because of the configuration received from the BSC or site constraints.
The BSS feature BTS Power Saving might raise this alarm when the traffic load is continuously low. The alarm has a filtering time of one week before the alarm
is raised.
To enable antenna hopping, at least one antenna system must include two enabled TXs, connected to separate antennas.
Action Follow the instructions below until the fault is resolved.
• Check the BSC configuration of Antenna Hopping.
• Read the IDB and use the Radio view in the OMT to check how the IDB is defined regarding the connections.
Undefine Antenna Hopping with the BSC if not feasible
