Chapter 3 WLAN Radio Frequency Design Considerations
Planning for RF Deployment
When making your estimation for separation, remember to factor in objects that affect RF coverage such
as wall densities, machinery, elevators, or even wide open spaces with steel cages, because your results
may vary depending on the RF environment. Be sure to include transient dynamics such as forklifts,
large groups of people, or large objects moved through the area by crane or similar load bearing devices.
A WLC is often a very effective method for preliminary site evaluation, by allowing a fast deployment of
a WLAN infrastructure that can then be used to make RF measurements of the area; a hand-walked site
survey is also effective insurance for complex areas such as those commonly found in healthcare, retail,
and manufacturing.

Location-Based Services Deployments
The third type of deployment is the location-based services (LBS) deployments, which may be the most
complex of current applications because it relies not only on excellent cell coverage, but optimal
location of APs. Location management deployments can simultaneously track thousands of devices by
using the WLAN infrastructure. Examples include Wi-Fi tag type deployments or asset tracking
deployments to locate equipment or devices via the wireless network and/or simply to indicate where
wireless clients are throughout the wireless network in relation to a drawing or diagram. This can be used
to make the wireless infrastructure more secure by providing the location of a rogue client or APs, and
greatly improve client troubleshooting capabilities.

For a location management deployment, the APs are laid out in a staggered pattern.
