BreezeACCESS Version 4.3 Installation
Manual Revision: 3.0
Installation Guidelines
This section describes the installation guidelines and the various
considerations that must be taken into account when planning the
installation.
Location of the Unit
The unit can be placed on a desktop or a shelf, or can be attached to
a wall.
The unit should be installed as near as possible to the antenna
(models with detached antenna). The RF cable connecting the unit
to the antenna should be as short as possible to guarantee
minimum power loss.
Keep the units well away from sources of heat, such as radiators,
air-conditioners, etc.
Location of the Antenna(s)
Any physical object in the path between two units can cause signal
attenuation. Common obstructions are buildings and trees. If a
unit’s antenna is installed indoors, the walls and/or windows
between the two sites are physical obstructions. Any buildings or
other physical structure such as trees, mountains or other natural
geographic features higher than the antenna and situated in the
path between the two sites can constitute obstructions.
Install indoor antennas as close as possible to a window (or wall if a
window is not accessible) facing the required direction. Avoid metal
obstacles such as metal window frames or metal film anti-glare
windows in the transmission path. Install outdoor antennas high
enough to avoid any obstacles, which may block the signal.
Position the antennas clear of metal furniture and away from
moving metal objects such as metal fans or doors.
Antenna Diversity
Multipath propagation is to be expected when there are potential
reflectors between the Access Unit and Subscriber Units. These
reflectors may be buildings or moving objects such as airplanes and
motor vehicles. If this is the case, the radio signal does not travel in a
straight line, but is reflected or deflected off of the object, creating
multiple propagation paths.
In applications where no multipath propagation is expected, a single
antenna is sufficient to ensure good performance levels. However, in
cases where multipath propagation exists, Alvarion recommends that
two antennas be used. This takes advantage of space diversity
