Basic WCDMA RF Optimization

Number of View: 404

RF optimization includes the following aspects:

? Pilot signal coverage optimization It includes the following two parts:

• ? Weak coverage optimization for ensuring seamless coverage by pilot signals in the network
• ? Primary pilot cell optimization for ensuring proper coverage areas by each primary pilot cell, clear edge of primary pilot cells, and that alternation of primary pilot cells is reduced as possible.

? Pilot pollution optimization

Pilot pollution refers to that excessive pilots of approximately equivalent strength cover an area without a primary pilot. Pilot pollution might cause increasing of downlink interference, call drop due to frequent handover, low network capacity. The problems must be solved by adjusting engineering parameters.

? Handover optimization It consists of two parts:

• ? Checking missing neighbor cells, verifying and perfecting list of neighbor cells, solving handover, call drop, and downlink interference problems.
• ? Ensuring proper SHO Factor based on DT by adjusting engineering parameters properly.
