
In some cases it might be necessary to up/down-tilt the antenna. An optional
Tilt accessory for the ODU providing a tilt range of ±15° is available. The tilt
option may be necessary to either improve the link conditions or, if the SU is
too close to the BTS, to reduce the receive signals strength. As a rule of thumb,
if the SU is located at a distance of less than 300 meters from the BTS, it is
recommended to up-tilt the antenna by approximately 10° to 15° (especially in
line-of-sight conditions) to avoid saturation of the receivers by too strong
signals.

Outdoor units with a connection to an external antenna should be installed as
close as possible to the antenna.

The equipment is designed for fixed, point-to-point operation. That is, in the
same time, the same CPE cannot connect to multiple BTSs; It is the
responsibility of the operator and the installer to take into account that - at
least in the 5725-5850 MHz band - the equipment excludes the use of point-to
multipoint systems, omnidirectional applications, and multiple co-located
intentional radiators transmitting the same information.
2.1.3 IDU-ODU Cables
Use only Category 5E Ethernet cables from either Alvarion or any of the approved
manufacturers, listed in
Table 2-1 . Consult with Alvarion's specialists on the

NOTE
The length of the Indoor-to-Outdoor cable should not exceed 90 meters. The length of the
Indoor-to-Outdoor cable, together with the length of the Ethernet cable connecting the CPE-IDU-1D
