softer/soft handover

Soft handover Factor
Active Set Size Uu_ActiveSet_Count Percentage(%)
1 4785 0.615
2 2140 0.275
3 853 0.11
SHO Factor= 0.615 * 1+ 0.275*2 + 0.11 *3 = 1.495
1.2 < SHO Factor <1.7 is OK.

Hi Mate,

Any idea how to resolve SHO Overhead issue? As currently we are having all antenna in W850 where pilot pollution cleaning are hardly to be done, any other idea how to deal with SHO overhead?

thank you

hi,
i'm afraid if your network suffers from pilot pollution, it is bound to have SHO problems (based on typical site arrangments and antenna patterns).
downtilting and pilot power reduction are the only ways to reduce pilot pollution which gradually will reduce SHO.

Electrical Downtilting should be preferred rather than Mechanical DT. You will see better improvement in SHO.
Anyway, the best (and more expensive) way to reduce a footprint is still to lower your antenna by a few meters...
