cases, a room originally built for a specific purpose, such as a radiology
lab, can be converted into something completely different, such as a
conference room. The blueprint can also show areas proposed for
future building expansion.
• Mark possible wireless handset usage locations on the blueprint and
refer to the marked blueprint during the physical walk-through and
inventory.
Walk-through and survey
Conduct a physical walk-through and survey:
• Document any items or materials near a proposed AP location that might
interfere with reception or transmission and affect wireless handset
performance, such as metal shelving.
• Document stock and inventory levels, current environmental conditions,
and any materials that can interfere with wireless handset transmissions.
• Walk around the site with a site survey tool before installing APs.
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.
RF transmission testing
After the APs are installed and configured, 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 handsets 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 which tools are provided
and which approach is recommended for deploying their APs.
Adjust the APs as needed.
Example of AP placement
Figure 4 "Sample AP placement diagram for b radio" (page 45) is an
example of an AP placement diagram based on the results of a site survey.
