Site planning and hardware deployment
• Sensitive electronic equipment
Check whether sensitive electronic equipment is present, for example, laboratory or
medical equipment. Although the transmitted power of the DAPs is low (about 250 mW),
it can interfere with some sensitive electronic equipment.
• Traffic information
Gather information about user density, amount of traffic, and whether redundancy is
required. You require this information to determine the number of DAPs that are required
and therefore the required cabling.
A DAP must always have at least one channel free to allow handover (either intracell or
intercell handover). Make sure that the maximum expected traffic density is not more than
11 channels simultaneously.
For more information, see
Speech quality
A relationship always exists between coverage and speech quality. The greater the distance
between the handset and the DAP, the lower the quality. Therefore, you must understand the
relationship between the coverage and the expected voice quality. For an illustration of the
relationship between coverage and voice quality in an open environment, see
Coverage and speech quality in an open environment.
