SD Drop Causes

[parsarka]

Hi everyone,

i would just like to ask what can be the main causes of High SD Drops we encountered in some sites.
i have checked the Hardware via MML and no alarms were found, but the quality of TRXs are low.
can this still be caused by the hardware?
there are also no interference.
our vendor is NSN.
your feedback will be greatly appreciated.
thank you.

No need to so much analysis .....Enable Antenna Hopping feature in the cells with poor SD Drops.....ur SD Drops will reduce!!
