Introduction

Component Description

Antennas
The access point includes integrated diversity antennas for
wireless communications. A diversity antenna system uses two
identical antennas to receive and transmit signals, helping to
avoid multipath fading effects. When receiving, the access point
checks both antennas and selects the one with the strongest
signal. When transmitting, it will continue to use the antenna
previously selected for receiving. The access point never
transmits from both antennas at the same time.
The antennas transmit the outgoing signal as a toroidal sphere
(doughnut shaped), with the coverage extending most in a
direction perpendicular to the antenna. The antennas should be
adjusted to an angle that provides the appropriate coverage for
the service area. For further information, see "Positioning the
Antennas" on page 2-5.
LED Indicators

four status LED indicators, as
