ZyXEL Among First to Receive Mobile WiMAX 2.5 GHz Certification from WiMAX Forum®

Hsinchu, Taiwan, June 18, 2008 – ZyXEL Communications Corp. (TSE:2391), the world's leading WiMAX™ equipment vender, today announced that ZyXEL 2.5 GHz WiMAX MIMO Residential Gateway MAX-206M2 has received the Mobile Forum Certified™ seal of approval at the WiMAX Forum Global Congress in Amsterdam. ZyXEL is among the first group of WiMAX Forum member companies to receive this honor.

The WiMAX Forum® is an industry-led, not-for-profit organization formed to certify and promote the compatibility and interoperability of broadband wireless products based upon the harmonized IEEE 802.16/ETSI HiperMAN standard. A WiMAX Forum goal is to accelerate the introduction of these systems into the marketplace. WiMAX Forum Certified™ products are fully interoperable and support broadband fixed, portable and mobile services. Along these lines, the WiMAX Forum works closely with service providers and regulators to ensure that WiMAX Forum Certified systems meet customer and government requirements.

The ZyXEL MAX-206M2 has gone through a rigorous test plan and it has met all interoperability and conformance standards required. With the Mobile WiMAX 2.5 GHz certification, the WiMAX technology from ZyXEL is proven and it also ensures the interoperability of ZyXEL's WiMAX products with other certified Mobile WiMAX equipment deployed by more than 305 WiMAX service providers among 118 countries worldwide.

"The WiMAX Forum would like to thank ZyXEL and the other member companies that have worked so hard to achieve today's milestone and enabling the Forum to continue to reach critical objectives with the ongoing certification of Mobile WiMAX equipment," said Ron Resnick, president of the WiMAX Forum, during a press conference at the WiMAX Forum Global Congress in Amsterdam. "ZyXEL has played an important role in WiMAX Forum's success of driving market momentum by enabling us to move closer to delivering on our plan to certify more than 100 Mobile WiMAX products in 2008. Our six independent WiMAX Forum certification labs are on now online to manage the anticipated increase of products to be submitted for certification."

"It is a great honor for ZyXEL being one of the world's first vendors to receive the Mobile WiMAX 2.5 GHz certification given by the WiMAX Forum," said Dr. Yuh-Long Chen, President of ZyXEL. "As the leading WiMAX device vendor, ZyXEL commits to contribute its best to the development and promotion of Mobile WiMAX technology."

ZyXEL has been devoting itself to WiMAX product development since 2005. Instead of producing IEEE 802.16d fixed WiMAX products, ZyXEL leaped ahead with latest IEEE 802.16e mobile WiMAX technology from the day one of WiMAX product development. Being an end-to-end Mobile WiMAX solution provider, ZyXEL has field proven products ranging from data cards, outdoor and indoor CPEs to Pico and Femto base stations; the company not only leads the WiMAX market with unparalleled expertise and products, but also has been recognized by international awards such as "Best of WiMAX World USA" in two consecutive years since 2006.
The ZyXEL MIMO Residential Gateway MAX-206M2 with two Ethernet and two VOIP ports provide users with seamless broadband wireless connectivity to surf the internet and IP telephony service at home or office under WiMAX coverage. Combined with TR-069 and OMA-DM protocols, MAX-206M2 facilitates the remote management of operators during deployment and operation stages to reduce the management costs.

"ZyXEL has been very successful on international projects cooperating with WiMAX service providers. We believe that being one of the first vendors to receive the Mobile WiMAX 2.5 GHz certification is just another acclamation to our efforts driving the standardized Mobile WiMAX technologies in the broadband wireless ecosystem." said Dr. Yuh-Long Chen, President of ZyXEL.
