Next Generation Solution for High Capacity, Long Distance Wireless Transport Networks

SANTA CLARA, California, November 10, 2010 - Aviat Networks, Inc. (Nasdaq: AVNW), a leading wireless expert in
advanced IP migration solutions, today introduced the Aviat WTM 6000, the
industry's first all-packet trunking radio, designed to support up to 4
Gbit/s of aggregate data throughput. The WTM 6000 is designed for long
distance, high capacity wireless transmission applications, with a compact
indoor architecture, superior performance and a highly redundant design to
ensure exceptional system availability. For the first time, the WTM 6000
incorporates the latest packet transport features that have until now only
been available in lower capacity microwave systems, such as built-in Ethernet
switching, link aggregation and traffic prioritization and Quality of Service
controls. First shipments of the WTM 6000 will commence in initial frequency
bands in the early part of 2011.

The WTM 6000 is the highest density wireless trunking solution on the
market, being the first system to accommodate up to 16 radio channels in a
single sub-rack. With integrated switching and native Ethernet/IP support,
the WTM 6000 also provides optional support for NxSTM-1 traffic, enabling
operators to maintain legacy TDM services without having to use inefficient
circuit emulation. The WTM 6000 is also the first trunking radio in its class
to support 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

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

"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."

The WTM 6000's all-indoor design is optimized to efficiently accommodate
complex system configurations, and is not restricted by being adapted from a
split-mount radio design. A highly compact baseband/transceiver module
eliminates cable interconnections and optimizes available rack space for
additional networking equipment. This makes for easy installation and
commissioning and simplified maintenance. The innovative Branching Unit (BRU)
design provides easy, cost-effective system expansion through the addition of
radio channels.

Aviat Networks will showcase the WTM 6000 IP trunking radio at AfricaCom,
to be held in Cape Town, South Africa, from November 10 to 11, 2010, booth
number A3A.
