Introducing BreezeNET B
BreezeNET B is a high performance wireless bridge system that provides
high-capacity, high-speed point-to-point links. The BreezeNET B system
operates in the unlicensed UNII band of 5.8 GHz and utilizes advanced
technologies to support optimal performance in spectrally poluuted
environments. BreezeNET B products operate in Time Division Duplex
(TDD) mode, using Orthogonal Frequency Division Multiplexing (OFDM)
modulation with Forward Error Correction (FEC) coding. Using the
enhanced multi-path resistance capabilities of OFDM modem
technology, BreezeNET B enables operation in near and non-line-of-
sight (NLOS) environments. These qualities enable service providers to
reach a previously inaccessible and broader segment of the subscriber
population. The system also features adaptive modulation for automatic
selection of modulation schemes, including BPSK, QPSK, 16 and 64
QAM to maximize data rate and improve spectral efficiency.
BreezeNET B supports sensitive applications through optional use of
authentication and/or data encryption utilizing WEP or AES algorithm
with 128-bit keys. The system supports Virtual LANs based on IEEE
802.1Q, enabling secure operation and Virtual Private Network (VPN)
services and enabling tele-workers or remote offices to conveniently
access their enterprise network.
BreezeNET B products are currently available in the 5.725-5.850 GHz
frequency band. The actual operating frequencies used by the system
can be configured according to applicable radio regulations and specific
deployment considerations.
BreezeNET B system components can be managed using standard
management tools through SNMP agents that implement standard and
proprietary MIBs for remote setting of operational modes and
parameters. The BreezeCONFIG utility is an SNMP-based application
designed to manage BreezeNET B system components and upgrade unit
software versions. The system administrator can use the BreezeCONFIG
utility to control any number of units from a single location. In addition,
BreezeCONFIG enables loading an updated configuration file to multiple
units simultaneously, thus radically reducing the time spent on unit
configuration maintenance.
