Harmony 802.11B Access Point Model Numbers - Proxim Harmony 8550 Manual

Harmony 802.11b Access Point Model Numbers

There are two models of the Harmony 802.11b Access Point available. Both models
offer the same functionality and have the same user interface.
Model 8550 is a Harmony 802.11b Access Point that ships with an integrated antenna
that provides diversity. This antenna supports two positions: up and down. For best
results, place the antenna in the up or vertical position, as shown in Figure 1 on page 13.
The integrated antenna cannot be removed from the Model 8550 Access Point.
Model 8551 is a Harmony 802.11b Access Point that ships with two Reverse polarity
TNC connectors (also known as R-TNC). This model supports external antenna options
that can increase the range of the Harmony 802.11b Access Point. It includes two
antenna connectors to support antenna diversity, which can improve system reliability.
Due to the characteristics of radio waves, it is possible that one antenna may provide
better performance than a second antenna installed a short distance away. Note that a
second antenna provides diversity only; it cannot be used to further increase the range of
the Access Point or increase its coverage area. When two antennas are connected to the
Access Point, only one antenna is in use at any point in time.
The Model 8551 Access Point ships with two 1-dBi omnidirectional antennas (Model
7015) that connect directly to the unit's R-TNC antenna connectors. High-gain external
antennas and antenna cabling for the Model 8551 AP are sold separately. Contact your
Harmony reseller for information on the available antennas that have been certified for
use with this Access Point.
