Comprehensive solutions meeting broadband, wireless and mobile needs

Hsinchu , Taiwan , May 14, 2007 ZyXEL Communications (TSE: 2391), the world's leading broadband access solutions provider, today debuts its latest WiMAX solutions in the Taipei WiMAX Summit. The company's current WiMAX range consists of the MAX-100 PCMCIA card, along with the MAX-200 and MAX-300 router/CPEfor indoor and outdoor deployments. The series not only offers an IP-based infrastructure with astounding broadband, wireless and mobile capability for service providers, but also empowers users with versatile applications and significantly lower operating cost.

"As WiMAX technology becomes more sophisticated, ZyXEL has long realized its enormous market potential to develop the products early," said Dr. Yuh-Long Chen, ZyXEL's President. "ZyXEL's WiMAX base stations and the MAX-100/MAX-200/MAX-300 series are leading the 802.16e-2005 device market. The series interoperates with other leading WiMAX base station providers such as Alcatel, Nortel and Nokia in different fields or bands, and ZyXEL is working closely with these world-renown companies for mutual opportunities on international WiMAX deployment projects, and to offer end users with quality services."

In areas where network cabling is difficult to deploy, service operators demand broadband solutions with low cost, easy deployment and supports to "Triple-Play" applications. More than satisfying customer needs, the MAX-100/MAX-200/MAX-300 series also works perfectly with other carrier-grade products from ZyXEL. As preferred by operators, ZyXEL MAX-100/MAX-200/MAX-300 series is expected to revolutionize the wide-area wireless broadband experience for users.

As many WiMAX products available in the market emphasize only on WiMAX access more than functional integration, ZyXEL takes full advantage of its technical strength in xDSL, network security and VoIP,to provide highly integrated WiMAX solutions.

Among the WiMAX-related developments, the VoIP access demonstration has emerged as the most coveted one; since service providers can offer value-added voice services to generate morerevenue. ZyXEL's WiMAX series supports the SIP standard as well as voice data compression and QoS (Quality of Service) mechanisms for IP phone with quality comparable to conventional paid voice services. Additionally, as network security becomes indispensable for wireless access, the products with these concerns addressed will soon develop into the favorable choices ofservice providers.

Today, ZyXEL's WiMAX series has won recognition from many domestic and international customers. For instance, the company partnered with Alcatel-Lucent to implement the pilot WiMAX deployment program in North America, Japan and Europe; ZyXEL also helped Chunghwa Telecom , Taiwan's largest telco operator, to builds a 802.16e mobile WiMAX network in Taoyuan.Backed by its innovative technology and global vision, ZyXEL is bound to bring more competitive WiMAX solutions to the next-generation network infrastructure.
