computer is located in a metal shed, you will need at least one Access
Point located outside the metal shed.
The more walls you try to transmit through, the more the signal
breaks down. Walls that have metal studs (interior office walls)
and concrete walls with steel rebar slightly degrade the signal with
each wall you try to go through. Metal walls may require the use of
Relay Stations to achieve adequate coverage.
Organic material absorbs RF energy. If you are trying to operate in
an area with lots of densely packed organic material (bags of beans or
corn), expect and plan for reduced operating ranges.
Raise the Access Point. Sometimes just raising the Access Point 12 feet
will dramatically increase your operating range, especially in a warehouse
or grocery store environment. Mounting the Access Point on the ceiling
with the antenna pointing vertically (up or down) is the best.
