Alvarion BreezeMax ASN-GW All-in-One WiMAX Network

All-in-One WiMAX Network Functionality

Alvarion’s BreezeMAX Access Service Network Gateway (ASN-GW) offers the complete set of network functionality needed to provide radio access to WiMAX subscribers. BreezeMAX  ASN-GW is based on an innovative distributed architecture, which optimizes deployment planning and allows a pay-as you-grow deployment strategy. The  ASN-GW is an integral part of Alvarion’s carrier-class, field proven 4Motion® Mobile WiMAX™ solution.

Innovative Fractalized ASN-GW Approach

The BreezeMAX ASN-GW offering encompasses a Mini-Centralized  ASN-GW and a complementary Integral ASN-GW, which employ the same software and feature set. Alvarion’s fractalized ASN-GW approach divides a single ASN-GW serving multiple base stations into an optimal number of identical collocated ASN-GWs serving a larger number of base stations. This enables operators to enjoy the economic and performance benefits of a distributed approach, as well as a centralized one when needed, optimizing deployments based on geography and reducing TCO.

BreezeMAX ASN-GW Highlights

• Stackable ASN-GW model
• Subscriber management capabilities
• Mobility efficiency
• VLAN CS & IP CS coexistence
• Multiple host implementation
• Multiple applications QoS
• Voice enhanced real time capabilities

The Distributed Architecture Advantage

Based on a pay-as-you-grow approach, Alvarion’s distributed architecture enables operators to reduce costs by minimizing initial investments and expensive backhauling costs. With lower bandwidth dimensioning, inter-node bandwidth is better utilized compared to a centralized approach and there is a better operator transport topology fit which enables operators to adapt the ASN-GW location to their transport topology. Subscribers also benefit as the service edge is brought closer to the user for high service availability which minimizes loss-of-service and provides faster services. Scalable from just a few hundreds to millions of subscribers, it is an ideal way to service a mixture of fixed and mobile services.

Enabling Optimized TCO

By optimizing the ASN-GW sites while keeping the distributed ASN-GW architecture, operators can benefit from lower entry costs and reduced CAPEX. Utilizing the optimal number of ASN-GWs OPEX is lowered as well as maintenance and operational expenses, and new opportunities are introduced to build networks in mixed Mini-Centralized  ASN-GW / Integral ASN-GW deployments.

Maximum Deployment Plan Flexibility

BreezeMAX ASN-GW enables optimized, dynamic geography balance, bringing the service edge closer to the user and with limited constraints on site placement. Reliability is also increased due to flexibility in redundancy configuration (N+1).
