to two internal radio heads.
The different models of the unit can provide the following operational modes:
1 Single WiMax SoC using 2
nd
Order Diversity - This system operation mode can
be applicable in licensed and unlicensed frequency bands providing up to
10MHz BWs per sector.
2 Dual WiMax SoC using 2nd Order Diversity - This system operation mode can
be applicable in licensed and unlicensed frequency bands providing up to
20MHz BWs per sector.
The BTS housing depends on power consumption figures; The following figures
show the BTS cases of the high power and low/medium power BTSs.
1.3.1 Antenna
In the BreezeMAX Extreme architecture, the antenna is approached as an
independent element. This provides the operator with the flexibility to select the
antennas source according to its supplier policy. To ensure the availability of
antennas that complement the BreezeMAX Extreme solution, Alvarion works
closely with several antenna suppliers to ensure availability of antennas that
comply with its requirements.
