BreezeACCESS MMDS Series 1 SU A/E Subscriber Units Installation Manual
1. INTRODUCTION
This manual describes installation guidelines for BreezeACCESS MMDS SU-A
and SU-E series of Subscriber Units.
The BreezeACCESS IP Broadband Wireless Local Loop (WLL) system allows
access service providers to provide high-speed IP connectivity services to their
subscribers. To effectively support IP-based services BreezeACCESS systems
employ wireless packet data switching technology.
The BreezeACCESS MMDS line of products uses Frequency Hopping Spread
Spectrum radios that operate in Time Duplex Division (TDD) mode in the
2.500GHz – 2.686GHz frequency range.
SU-A and SU-E series Subscriber Units are comprised of an indoor unit (SU-NI)
and an outdoor unit. In the SU-A product line, the outdoor unit (SU-RA)
contains the radio module and an integral flat antenna. In the SU-E series, the
outdoor unit (SU-RE) contains the radio module and an interface to an external
antenna (not included). The indoor unit provides the interface to the user’s
equipment and is powered from the mains via its SU-PS power supply unit. The
SU-NI also contains an IF (Intermediate Frequency) module and is connected to
the outdoor unit via a 50-ohm coaxial IF cable. The IF cable serves for
transmission of the 440MHz IF signal between the indoor and the outdoor units.
It also serves for transferring power (12VDC), management and control signals
from the indoor unit to the outdoor unit.
The SU-A/E-D-MMDS series include the following products:
• SU-A/E-1D-MMDS: supports a single Ethernet device
• SU-A/E-8D-MMDS: supports up to 8 Ethernet workstations/PCs
