BreezeACCESS 4900 6 System Manual
BreezeACCESS 4900 Access Units, and a different power supply module, suitable
for GFSK equipment, is required for powering the BreezeACCESS GFSK Access
Units.
Each BS-AU module and its outdoor radio unit (AU-ODU) comprise an AU E-BS
Access Unit that together with an external antenna serve a single sector/cell.
There are two types of Access Units, differing in the maximum number of
Subscriber Units that they can serve:
The AU-BS Access Unit can serve up to 512 Subscriber Units (124 when Data
Encryption is used).
The AUS-BS Access Unit can serve up to 25 SUs except SU-54 (refer to
“Subscriber Unit” on page 8 for details on availability of SU types in different
bands). Optionally, it may be licensed to support also SU-54 units (in bands
where SU-54 unit type is available.).
The AU-ODU outdoor unit contains the processing and radio modules and
connects to an external antenna using a short RF cable.
E model units are supplied without an antenna.
The available antennas are listed in Table 1-1.
The BS-AU indoor module connects to the network through a standard IEEE
802.3 Ethernet 10/100BaseT (RJ 45) interface. The indoor module is connected to
