2.2 Equipment Positioning Guidelines
This section provides key guidelines for selecting the optimal installation
locations for the various BreezeACCESS 4900 system components.
CAUTION
ONLY experienced installation professionals who are familiar with local building and safety codes
and, wherever applicable, are licensed by the appropriate government regulatory authorities should
install outdoor units and antennas.
Failure to do so may void the BreezeACCESS 4900 product warranty and may expose the end
user or Service Provider to legal and financial liabilities. Alvarion and its resellers or distributors are
not liable for injury, damage or regulation violations associated with the installation of Outdoor Units
or antennas.
Select the optimal locations for the equipment using the following guidelines:
The outdoor unit can be either pole or wall mounted. Its location should
enable easy access to the unit for installation and testing.
The higher the placement of the antenna, the better the achievable link
quality.
AU-ODU units should be installed as close as possible to the antenna.
The antenna connected to the AU-ODU unit, should be installed so as to
provide coverage to all Subscriber Units (SUs) within its service area.
NOTE
The recommended minimum distance between any two antennas serving adjacent sectors is 2
meters. The recommended minimum distance between two antennas serving opposite cells
(installed back-to-back) is 5 meters.
The antenna of the SU (integrated on the front side of SU-A-ODU and SU-A-H-
ODU unit) should be installed to provide a direct, or near line of sight with the
Base Station antenna. The antenna should be aligned to face the Base
Station.
The indoor equipment should be installed as close as possible to the location
where the indoor-to-outdoor cable enters the building. The location of the
indoor equipment should take into account its connection to a power outlet
and the CPE.
