Aviat Networks introduced an all-packet trunking radio designed to support up to 4 Gbps of aggregate data throughput. The new WTM 6000 microwave system features built-in Ethernet switching, link aggregation and traffic prioritization and Quality of Service controls. The compact indoor architecture can accommodate up to 16 radio channels in a single sub-rack. It provides optional support for NxSTM-1 traffic, enabling operators to maintain legacy TDM services without having to use circuit emulation. 
The WTM 6000 supports 256QAM Adaptive Coding and Modulation (ACM) to enable operators to achieve higher link capacities with smaller antennas, which in turn reduces tower loading and infrastructure costs. The WTM 6000 will be introduced in the 4 to 13 GHz frequency bands to enable paths in well in excess of 50 miles.
Two different solutions are now available for link protection. In addition to the traditional N+1 protection, where one standby radio channel is used to protect up to seven active transport channels, the IP architecture of the WTM 6000 now enables the option for bonding of multiple radio channels together, using Ethernet Link Aggregation, to provide full wire-speed Gigabit throughputs. In the event that one radio channel fails, the integrated switch can prioritize important traffic to be maintained over the remaining bandwidth. This enables costs savings by eliminating the standby protection channel.
Commercial availability is expected in the early part of 2011.
“The Aviat Networks WTM 6000 represents the next-generation microwave solution for high-capacity, long-haul all-IP and hybrid trunking applications, all with fiber-like speeds,” says Shaun McFall, senior vice president and chief marketing officer, Aviat Networks. “As a leading provider of trunking microwave solutions around the world, we are excited to introduce this major step forward to enable operators to introduce efficient high-speed IP transport into their backbone microwave networks.”http://www.aviatnetworks.com
