1.1 Introducing BreezeACCESS 4900
BreezeACCESS 4900 is a high capacity, IP services oriented Broadband Wireless
Access system operating in the 4.9 GHz licensed spectrum band allocated for
public safety. The system employs wireless packet switched data technology to
support high-speed IP services with a network connection that is always on. The
system is designed for both Point-to-Point and Point-to Multipoint configurations,
supporting data, VoIP and video applications.
The system supports Virtual LANs based on IEEE 802.1Q, enabling secure
operation and Virtual Private Network (VPN) services. The system supports layer-
2 traffic prioritization based on IEEE 802.1p and layer-3 traffic prioritization
based on either IP ToS Precedence (RFC791) or DSCP (RFC2474). It also supports
traffic prioritization based on UDP and/or TCP port ranges. BreezeACCESS 4900
uses advanced security mechanisms, including WEP128, AES128 and FIPS
compliance.
Using OFDM modem technology and high power radios, BreezeACCESS 4900
offers an unmatched combination of wide coverage, high capacity and value-
added features to provide wireless connectivity that works also in near and
non-line-of-site (NLOS) conditions.
Alvarion’s Complete Spectrum solution enables the BreezeACCESS 4900 to
integrate seamlessly into other BreezeACCESS networks. Supporting both fixed
and mobile platforms at multiple frequency bands, the Complete Spectrum
enables simultaneous deployment of systems at 900 MHz, 2.4 GHz, 3.5 GHz,
4.9 GHz, and the entire 5 GHz band.
