Mobile Applications - Alvarion BreezeNET PRO.11 Series User Manual

Point-to-Point installations require directional antennas at either end of the link. To
select the best antenna for a specific application, consider the following factors:
Distance between sites
Required throughput
Clearance between sites
Cable length.
Refer to Section 5.3.7 to determine the best combination of antennas for your
application.
5.1.1.2 Point-to-Multipoint
Point-to-Multipoint applications consist of one or more APs at the central site and
several remote stations and bridges (SA-10, SA-40, WB-10). In this configuration,
use an Omni-6 antenna with the Access Point because of its 360 radiation pattern.
In the United States, the Omni-7.2 antenna (which also has a 360 radiation pattern
but has a wider range) can also be used. The Omni-7.2 antenna comes with a 20ft.
low loss cable and a mast mount bracket for rooftop installations.
The remote units should use directional antennas aimed in the direction of the AP's
antenna(s).

5.1.1.3 Mobile Applications

In mobile applications, station orientation changes continuously. In order to
maintain connectivity throughout the entire coverage area, most mobile applications
require omni-directional antennas for both Access Points and wireless stations. In a
motor vehicle, for example, you can install an SA-10 in the cabin, and mount the
antennas (in most cases an Omni-6) on the roof.
