Equipment Location Guidelines
This section provides key guidelines for selecting the optimal
installation locations for the various BreezeACCESS 900 system
components.
WARNING
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:
Units should be installed in easily accessible locations to facilitate
installation and testing.
The higher the placement of the antennas, the better the achievable
link quality. Locate the AU's antenna at least 20 cm (8 in.) away
from any other antenna.
The antenna of the AU should be installed as close as possible to
the AU-RE Radio Unit to minimize loss in the RF cable. The antenna
should be installed so as to provide coverage to all Subscriber Units
within its service area.
NOTE
The AU equipment complies with the ETS 300 385 standard and is protected
against secondary lightning strikes when the Radio Unit and antenna are 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).
