analyzer mode that picks up on the noise characteristics per
channel, and includes an option for automatically making
clearest channel selection
•
Flexible network planning - 10MHz and 20MHz channel
options for radio planning, interference avoidance and increased
cell capacity

outstanding coverage, multi-subscriber profiles in same sector
and network, modular and flexible "pay-as-you-grow", enables
fewer base stations and site constructions
•
Lower CAPEX tomorrow - with future investment protection
due to co-location of future WiMAX with BreezeACCESS VL
enabling both sets of CPEs to operate at the same time in the
same sector, AlvariSTAR management tool will support all
Alvarion's WiMAX platforms providing seamless management
migration
•
Out-of-the-box low cost installation -
•
10 LEDs SNR BAR display on outdoor unit for fast antenna
alignment without need for external tools or monitors,
standard IDU-ODU CAT5 cable and best AU mode for fast
association
•
Optimal performance and connectivity through always-on
adaptive modulation and automatic transmit power control
(ATPC)
•
Over-the-air software upgrade for easy, cost-saving installation
and maintenance
•
Over-the-air configuration and monitoring
•
Automatic distance measuring during installation for
optimization of cell performance
•
Lower OPEX - by requiring fewer base stations, remote
management, firmware and configuration download/upload,
effective diagnostic tools, self-adaptive to environmental
changes (automatic modulation and ATPC)
Management Advantages
•
Advanced management features including:
•
MAC pinpoint - enables fast identification of the SU using
the MAC address of the network station.
•
Remote blocking - a simple message to stop service due to
non payment.
•
AlvariSTAR - a comprehensive network management support
tool with scalable architecture, topology management,
configuration and monitoring, fault management, and
performance monitoring
•
BreezeCONFIG - a configuration and monitoring utility that
is intuitive and simple to use and enables simultaneous firmware
upgrades for multiple CPEs

Extensive Access Suite Features
•
Bridging functionality - simple configuration, fast installation
802.1Q VLAN support with trunk, access and hybrid modes
•
QoS - quality of service using packet prioritization
•
SLA enforcement - supports different user profiles in the same
sector with committed information rates (CIR) and maximum
information rates (MIR) per user, per direction; packet
prioritization with layer 2 (802.11P) and layer 3 (IP TOS)
classification, and graceful degradation in case of congested
sector
Security and Filtering Options
•
AES 128 and WEP 128 encryption options
•
Access control with IP address protocol and MAC based
filtering, offering better control including being able to limit
the number of authorized IP addresses; that can be used to
create additional sources of revenue or for preventing local
broadcasts from flooding the wireless link
Flexibility and Modularity
•
Flexible topology allowing stand-alone or chassis based
configurations for modular and scalable solutions enabling
"pay as you grow". Deployable in multiple sectors using various
antenna choices
•
AC and DC power supply options
•
Supports CPE rates of 3Mbps, 6Mbps and 54Mbps
•
Upgradeable CPE bandwidth over the air
The Complete Spectrum
™
Solution
•
Covers the entire 5GHz band and easily integrates with
BreezeACCESS's 900MHz, 2.4GHz, and 3.5GHz bands using
the same infrastructure with a range of technologies including
OFDM, frequency hopping and hybrid digital modulation
•
Supports concurrent LOS, NLOS and multi-frequencies with
subscriber speeds from 3 to 54Mbps
•
Permits operators to customize networks for their unique
market demographics, topographic environments and business
model to achieve the highest revenue per cell with maximum
subscribers
Robustness and Reliability
•
Adaptive modulation with 8 modulation schemes and smooth
changes between rates responding to link conditions, facilitating

System Components
The BreezeACCESS VL solution consists of a base station and
customer premises equipment (CPE) units. The base stations are
available as either modular or stand-alone micro cell units. CPEs
are available in various models for differing bandwidths and
single or multiple user configurations.
Access Units (AUs)
Installed at the base station site, the AUs communicate with the
CPEs. Each AU includes indoor and outdoor units. The indoor
connects to the network through a standard IEEE 802.3 Ethernet
10/100BaseT (RJ-45) interface and to the outdoor unit using a
CAT-5 cable. Alvarion offers two types of base stations:
•
The modular shelf base station (BS-SH-VL)
19" 3U universal chassis. Each base station
shelf can hold up to six AU modules
(AU-D-BS), providing reliable access to a
maximum number of subscribers. Two power
supply modules can be used in a BS-SH-VL
chassis (either AC or DC) for fail-safe operation.
The AU-D-BS kit includes a chassis based
indoor unit, pole mounted outdoor unit and
sector antennas.
•
The stand-alone micro base station
(AU-D-SA) kit includes a small indoor unit,
pole-mounted outdoor unit and a sector antenna.
A variety of antennas can be used with the base
station: 360, 120, 90 and 60 degrees
Subscriber Units (SUs)
Installed at the customer premises, the
subscriber unit (SU) enables customer
connection with the base station and supports
single or multiple end users. SUs provide an
efficient platform for always-on, high-speed
Internet and Intranet, VoIP, VPN and other
services. Each SU connects to the network through a standard
IEEE 802.3 Ethernet 10/100BaseT (RJ-45) interface and connects
to its outdoor part via CAT-5 cable. Each SU kit includes a small
indoor unit, CAT5 indoor-outdoor cable, pole mounted outdoor
unit and integrated antenna on most cases.
Several CPE models are available:
•
The S U-A-ff-3-1D-VL supports gross rate of up to 3 Mbps for
a single user, includes integrated antenna
•
The SU-A-ff-6-1D-VL supports gross rate of up to 6 Mbps for
a single user, includes integrated antenna
•
The SU-A-ff-6-BD-VL supports gross rate of up to 6 Mbps for
multiple users, includes integrated antenna
•
The SU-A-ff-54-BD-VL supports gross rate of up to 54 Mbps
for multiple users, includes integrated antenna
•
The SU-E-ff-54-BD-VL supports gross rate of up to 54 Mbps
for multiple users, does not include antenna
