Chapter 1 - System Description
Introducing BreezeMAX
BreezeMAX 3500 is Alvarion's WiMAX platform for the licensed 3.5 GHz
frequency band. It leverages Alvarion's market-leading knowledge of
Broadband Wireless Access (BWA), industry leadership, proven field
experience, and core technologies including many years of experience
with OFDM technology.
Built from the ground up based on the IEEE 802.16/ETSI HIPERMAN
standards, BreezeMAX 3500 is designed specifically to meet the unique
requirements of the wireless Metropolitan Area Network (MAN)
environment and to deliver broadband access services to a wide range of
customers, including residential, SOHO, SME and multi-tenant
customers. Its Media Access Control (MAC) protocol was designed for
point-to-multipoint broadband wireless access applications, providing a
very efficient use of the wireless spectrum and supporting difficult user
environments. The access and bandwidth allocation mechanisms
accommodate hundreds of subscriber units per channel, with
subscriber units that may support different services to multiple end
users.
The system uses OFDM radio technology, which is robust in adverse
channel conditions and enables operation in non line of sight links. This
allows easy installation and improves coverage, while maintaining a
high level of spectral efficiency. Modulation and coding can be adapted
per burst, ever striving to achieve a balance between robustness and
efficiency in accordance with prevailing link conditions.
BreezeMAX supports a wide range of network services, including
internet access (via IP or PPPoE tunneling), VPNs and Voice over IP.
Service recognition and multiple classifiers that can be used for
generating various service profiles enable operators to offer
differentiated SLAs with committed QoS for each service profile.
BreezeMAX products are currently available in the 3.4 – 3.6GHz
frequency band, as shown in Table 1-1. The actual operating
frequencies used by the system can be configured according to
applicable radio regulations, license conditions and specific deployment
considerations.
