DragonWave Delivers 4 Gbps Wireless Links

DragonWave introduced its Horizon Quantum packet microwave radio system for mobile and access networks, capable of delivering up to a record-breaking 4 Gbps per link. The new DragonWave solution, which is optimized for the rollout of 4G services, features a native Ethernet implementation and sub-0.1-millisecond latencies. Clearwire plans to use the platform for its network.

DragonWave's Quantum packet radio leverages several innovations, including a unique "Bandwidth Accelerator" technology that allows it to achieve superior spectral efficiency. Depending on traffic type, the company said its Bandwidth Accelerator can deliver up to 5 times improvement in spectral efficiency with versus first generation microwave radios.

The half-rack-unit device incorporates key nodal-intelligence features and integrated switching capability. This enables Horizon Quantum to perform aggregation and serve as a switch for ring and mesh network architectures.

The Horizon Quantum -- scheduled to ship by the end of 2009 -- delivers interference-free performance in both licensed and unlicensed radio frequencies in the 6-to-38-GHz range. The carrier-grade DragonWave solution enables 99.999-percent service reliability, delivers advanced security and encryption and fully supports SynchE and other critical Ethernet data transport capabilities such as virtual local area network (VLAN) queuing/prioritization, flow control and jumbo packets. Its pseudowire capability enables Ethernet and Time Division Multiplexing (TDM) traffic to be collapsed on a single, packet-based network. The Horizon Quantum is easy to install, configure and maintain and can be remotely managed.

"Clearwire's position as a global leader in deploying 4G service places us at the forefront of backhaul network development where we are today building one of the world's largest, most dynamic and cost-effective microwave backhaul solutions," said Dr. John Saw chief technology officer of Clearwire "To meet the growing demand for high-speed mobile connectivity, we need increasingly powerful, intelligent and cost-efficient solutions to capitalize on demand for bandwidth intensive and runtime sensitive applications. Horizon Quantum will help us achieve even higher capacity in our backhaul network to serve the increasingly high-bandwidth demands of our customers."
