WLAN IP Telephony Installation and Configuration
RF transmission testing
Once the APs have been installed and configured, it is necessary to measure
the strength of the Radio Frequency (RF) transmissions. Signal strength
testing ensures that all usage areas have adequate coverage. This can be
performed in two ways.
1 Use the WLAN Handsets 2210/2211 to determine AP signal strength
using the Site Survey mode.
2 Use two portable computers with wireless hardware operating on a point-
to-point basis. Using diagnostic software provided by the AP vendor, a
coverage area for a potential AP can be determined by keeping one
portable computer in one place and moving around with the other
computer. Check with the vendor as to what tools are provided and what
approach is recommended for deploying their APs.
Example of AP placement
Figure 3 on page 38 is an example of an AP placement diagram.
