Outdoor Unit
The outdoor portion of the subscriber 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
• 5.3 GHz
• 5.8 GHz U-NII
The radio/antenna unit installed at the subscriber site must match the frequency band
employed at the base station.
Figure 2-2 Subscriber Outdoor Units
As shown in Figure 2-2, sizes of the antennas vary with the frequency band, from
approximately 9 inches square to approximately 13 inches square. Outdoor units
mount easily on a home or office roof, under the eave, or even in a properly-situated
window.
The subscriber antennas are directional, with a beam width of 17° to 20° horizontally
and vertically depending on frequency. The width of this beam, combined with the
width of the base station antenna beam, means that only rough pointing of the antenna
is needed for establishing a wireless link, though accurate pointing is important for
maximum signal quality.
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
technology minimizes the effects of obstructions in the path between the subscriber’s
antenna and the base station antenna.
