Outdoor Unit
The outdoor portion of the equipment consists of a single unit containing the radio and
antenna. Different models support various frequency bands:
•2.5 GHz MMDS
•3.5 GHz FWA
•5.8 GHz U-NII
Figure 1-2 Outdoor Units
As shown in Figure 1-2, sizes of the antennas vary with the frequency band, from approx-
imately 9 inches square to approximately 13 inches square. Outdoor units mount easily
on a office roof or on a tower. The antennas are directional, with a beam width of 17° to
20° horizontally and vertically depending on frequency.
Depending on distance, a line-of-sight path may not be required for establishment of a
wireless link between the subscriber and the base station. PacketWave’s OptimaLink
(TM)
technology minimizes the effects of obstructions in the path between the subscriber’s
antenna and the base station antenna.
