Planning
require approximately 150 kbps of bandwidth per call. Network traffic can be monitored
and analyzed using a network sniffer or an SNMP workstation.
• Number of other wireless devices per AP—The wireless handsets can share bandwidth
with other wireless devices. To ensure adequate RF bandwidth availability, consider the
number of wireless data devices in use per AP.
Important:
In a very large or complex site, it can be advisable to contract a professional site survey.

Effective site survey

Consider the following points for an effective site survey.
Network usage
Examine the network usage:
• How many people use a wireless handset?
• What areas of the site require wireless handset access?
• How many hours each day are wireless handsets typically in use?
• Which locations are likely to generate the largest amount of traffic?
• Where is future network expansion most likely?
Mobility requirements
Assess the mobility requirements:
• How many wireless handset users are in motion continually, such as in a warehouse or
hospital?
• How many users work from different fixed locations throughout the site?
Physical site study
Perform a study of the physical site:
• Study blueprints of the proposed site. A site blueprint provides a map of the site, including
the location of objects such as walls, partitions, and anything else that could affect the
performance of a wireless handset. This helps identify areas where wireless handsets
are less likely to perform well. Many obstructions are not readily visible and, in some
cases, a room originally built for a specific purpose, such as a radiology lab, can be
