Equipment Location Guidelines
This section provides key guidelines for selecting the optimal
installation locations for the various BreezeACCESS VL system
components.
NOTE
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 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 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.
NOTE
The system complies with the ETS 300 491-1 standard and is protected against
secondary lightning strikes when the Outdoor Unit is properly grounded according to the
relevant country specific industry standards for protection of structures against lightning.
The system complies with EN 61000 4 5 test level 3 (2kV).
