3 Planning a OpenScape 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.
