Wintegra and WiChorus Demonstrate Open Mobile WiMAX Solutions with Successful Interoperability Testing

AUSTIN, Texas--(Business Wire)--
Wintegra, a fabless semiconductor company and leading provider of
silicon and software solutions for WiMAX 802.16e and LTE base
stations, and WiChorus, provider of the industry's most scalable
Intelligent Wireless Core Platforms for WiMAX(TM) and LTE networks
today announced the successful completion of interoperability testing
(IOT) between WiChorus' Intelligent ASN gateway and Wintegra's Mobile
WiMAX base station technology. WiChorus and Wintegra demonstrated
seamless end-to-end connectivity between Wintegra's base station
technology platform and WiChorus' Intelligent ASN Gateway, based on
the R6 interface within the WiMAX Forum's NWG Specification.

WiChorus provides a new class of intelligent wireless core
platform that enables service providers to deploy large scale,
profitable WiMAX and LTE (long term evolution) networks. "WiChorus has
continued to show commitment to build an open eco-system for
best-of-breed WiMAX," said Rehan Jalil President and CEO of WiChorus.
"We are excited to partner with Wintegra and have them join our One
Open WiMax initiative. This testing offers our ASN-Gateway and Home
Agent customers significant added value by allowing them to get their
services to market more quickly by helping to realize the promise of
WiMax as a truly open and interoperable standard. We view Wintegra,
with their many base station design wins worldwide as a key partner
for this type of integration activity."

The partnership also benefits Wintegra's silicon customers by
allowing them the ability to accelerate their time to market for their
WiMax base station products. Wintegra and WiChorus have worked to
integrate and test their solutions as part of the Wintegra WiMAX 1.0
production release.

Wintegra will continue to invest in WiMAX technology to develop
new "cutting-edge" WiMAX features. Wintegra are planning a follow up
WiMAX 1.1 production release during the second half of this year that
will add to the feature set already supported. WiChorus and Wintegra
will continue to work together on a joint IOT program to ensure that
the mobile WiMAX experience is simplified and seamless for partners,
vendors, and mobile operators. In addition, the two companies are
collaborating on a similar initiative for LTE.

"OFDMA 4G technologies are now starting to be deployed around the
world", said Mike Phillip, the GM of Wireless Systems at Wintegra. "We
expect that the schedule for successful specification and deployment
of LTE equipment will be significantly accelerated from traditional 2G
and 3G cellular deployments. As such, the telecommunications equipment
manufacturers are looking for platforms that minimize the risk in
deploying these newer, flatter network architectures and the
partnership to test interoperability we have with WiChorus is a key
factor in aiding this success."

The One Open WiMAX initiative is helping to ensure fully open
WiMAX standards, including the adoption of a single open R6 interface,
and demonstrate multi-vendor interoperability across the entire mobile
ecosystem. WiChorus and Wintegra are making the goal of an open
ecosystem a reality ensuring service providers have the option to
combine best-of-breed equipment to build their networks through their
participation in the WiMAX Forum and the One Open WiMAX initiative.
