Introducing BreezeACCESS
BreezeACCESS IP Broadband Wireless Access system is an IP based
access system that supports wireless data and voice services, employing
wireless packet-switched data technology to support high-speed IP
services, including fast access to the Internet and Virtual Private
Networks.
BreezeACCESS users are provided with a network connection that is
always on, supporting access to the Internet and other IP services at
data rates of up to 3 Mbps. BreezeACCESS can also support high
quality telephony using the ITU-T H.323 industry standard for Voice
over IP communications. The system is designed for cellular-like
deployment, allowing systems of various sizes and structures to be
constructed. A system may include any number of cells, each
containing several Access Units, to better cover densely populated
areas.
The BreezeACCESS system allows the Maximum (data burst)
Information Rate (MIR) and Committed Information Rate (CIR) for both
uplink and downlink to be defined separately for each subscriber.
This enables a variety of Class of Service (CoS) packages, bandwidth
allocations and traffic-shaping schemes. In addition, the system
supports Virtual LANs based on IEEE 802.1Q, enabling secure
operation and Virtual Private Network (VPN) services as well as allowing
tele-workers or remote offices to conveniently access their enterprise
networks. The system also supports Layer 2 traffic prioritization
according to IEEE 802.1p and ToS based Layer 3 traffic prioritization
according to RFC791.
BreezeACCESS V operates in Time Division Duplex (TDD) mode. It
employs wireless packet data switching technology, utilizing Frequency
Hopping Spread Spectrum (FH-SS) radios.
BreezeACCESS V systems are available in the following frequency
bands:
BreezeACCESS V units operating in the 5.7 GHz band are available with
one of the following options:
 US Option – The available band ranges from 5.725 GHz to
5.850 GHz. This option supports the standard ISM US FCC
Frequency Hopping sequence that includes 79 frequencies.
Synchronization among AUs is not supported.
Series (band) Frequency Band
5.2 5.150-5.350 GHz
5.7 5.725-5.850 GHz
