Installing the Access Point
Before You Begin
Perform a Site Survey
Before installing the Access Point, perform a site survey to determine the optimal
Access Point placement for maximum range, coverage, and network performance.
When performing a site survey, consider the following factors:
■
Data rates : Range is generally inversely proportional to data rates. The maximum
radio range is achieved at the lowest workable data rate. Higher data rates will
generally be achieved at closer distances.
■
Antenna type and placement : Proper antenna configuration is a critical factor in
maximizing radio range. As a general rule, radio range is increased by mounting
the antennas higher off of the ground.
■
Physical environment : Clear or open areas provide better radio range than closed
or filled areas. The less cluttered the operating environment, the greater the
wireless range.
■
Obstructions, building materials, and sources of interference : Physical obstruc-
tions, such as concrete pillars, steel beams and filing cabinets can block or hinder
wireless communication. Avoid installing the Access Point in a location where
there is an obstruction between sending and receiving devices. A number of
machines and electronic devices that emit radio waves – cranes, wireless phones,
microwave ovens, satellite dishes – interfere with and block wireless signals.
Building materials used in construction also influence radio signal penetration.
For example, drywall construction permits greater range than concrete blocks.
