Outdoor Installation
Considerations
This section describes various considerations to take into
account when planning an outdoor installation including site
selection, antenna alignment, antenna polarization, antenna
seal, and cell size.
Collocating DS.11 Outdoor
Units
Up to three BU-DS.11 units with omni-directional antennas
(the exact number depends on the number of non-
overlapping channels available in the relevant regulatory
domain) can be collocated on the same building top or tower.
Collocating more then three units may decrease performance
depending upon the type of antenna and its direction. Each
unit should be assigned to one of the non-overlapping
channels: 1, 7, or 13 in ETSI or 1, 6 or 11 in FCC.
Site Selection Factors
When selecting a location for outdoor units and external
antennas, remember to take into consideration the following
guidelines:
♦ Minimum distance between sites.
♦ Maximum height above the ground.
♦ Maximum line of sight clearance.
