Installations in IDF Closets (Telecommunications or other Electrical
Equipment)
When installing APs near other electrical or telecommunications equipment, keep all wiring and metal
away from the antennas and avoid placing the antennas near electrical lines. Do not route wiring
electrical or Ethernet in the near field (6-15 inches) of the antenna. Try to refrain from installing the AP
in the electrical closet because the best place for the AP is as close to the users as possible/practical. If
you have remote antenna cables from in a closet, you may be required to use Plenum rated cable (see
local fire/safety regulations for more on this).

Site Survey Considerations
It is considered a good practice to conduct a site survey to assess cell coverage and look for problem
areas such as poor RF coverage or high retries. Always try to install the AP as close to the actual users
as possible or practical to do so.
If you have done a site survey with a previous product, chances are that the survey is still valid and you
only need to perform simple checks to verify that coverage holes or problem areas do not exist.
