3 Planning a HiPath Cordless IP System
When planning a cordless system, the position of the base station is critical for
system performance. The load should be optimized using locations with a high
call volumes and radio coverage.
3.1 Planning According to Call Traffic Load
The borders of base station radio cells should not be located in high traffic
areas because changing base stations during a call (handover) increases
traffic load.
The best base should be as unique as possible to avoid frequent switching.
