BreezeACCESS Version 4.3 System Description
Manual Revision: 4.0
X=A: The outdoor radio unit includes an integral high gain flat antenna
X=E: The outdoor radio unit has a connector for an external antenna.
FF: The radio band supported by the unit (5.2 or 5.7 GHz).
Base Station Equipment
The BreezeACCESS Access Units (AU) installed at the base station site
provide all the functionality necessary to communicate with the remote
Subscriber Units as well as to connect to the backbone of the service
provider. Each AU connects to the network through a standard IEEE
802.3 Ethernet 10BaseT (RJ 45) interface.
There are 2 lines of Access Units with different architectures:
 Modular Base Station Equipment
 Standalone “Micro-Cell” Access Unit
Modular Base Station Equipment
The Base Station equipment is based on the BS-SH 3U chassis, which is
suitable for installation in 19” racks. The chassis contains one or two
power supply modules, up to six active Access Unit Network Interface
(BS-AU) modules and an optional BS-GU GPS and Alarms module.
Two different types of power supply modules are available: the BS-PS
which is powered from a –48 VDC power source, and the BS-PS-AC,
powered from the 110/230 VAC mains. The optional use of two power
supply modules is for fail-safe operation through power supply
redundancy.
Each BS-AU module, together with its outdoor radio unit comprises an
AU-E-BS Access Unit that serves a single sector. The AU-RE outdoor
unit contains the radio module and a RF connector for a separate
external antenna.The BS-AU modules connect to the network through
standard IEEE 802.3 Ethernet 10BaseT (RJ 45) interfaces. A coaxial
Intermediate Frequency (IF) cable connects the indoor module to the
outdoor unit. This cable carries 440 MHz IF signals, power (12 VDC)
and management and control signals from the indoor unit to the
outdoor unit.
