Aperto Networks Continues Leadership in WiMAX Forum™, Releases Roadmap for Certification of PacketWave® Systems

Milpitas, Calif., (May 24, 2004) – Aperto Networks, a leading 802.16 class broadband wireless access (BWA) systems provider, today revealed its roadmap for WiMAX Forum certificationT, multi-vendor interoperability and shipment of fully IEEE 802.16 WiMAX-compliant systems. This roadmap will be implemented for all frequencies in which Aperto's carrier-class systems operate, i.e., in the 2.5 GHz, 3.5 GHz and 5 GHz bands.  

"Our overarching goal is to be a leader in achieving WiMAX certification, with a seamless path for both overlay and migration of our current customers' operations," stated Aperto Chairman and CEO Reza Ahy.  

"To accomplish this, Aperto's overlay strategy for our WiMAX Forum-certifiedT systems ensures that they fully interoperate with carriers' current deployment of PacketWave systems. We will enable both systems to seamlessly coexist in the same cell and sector, while continuing to deliver the features our customers have come to depend on, such as Quality of Service for guaranteed Service Level Agreements and dynamic per-subscriber link optimization for robust link performance and interference resilience. Providers can deploy both versions side-by-side to increase capacity and scale their operations, while maintaining common network management and provisioning tools."  

He continued, "We have been working with silicon suppliers and are already integrating their compliant components in our systems today. Demonstrable WiMAX systems will be available for interop testing by December 2004. We will be part of the WiMAX Forum's Plugfest in January 2005, and expect to begin commercial delivery by mid-2005."  

"The WiMAX Forum has created great interest in standardized, interoperable BWA systems," emphasized Emmy Johnson, principal analyst with Sky Light Research and leading BWA expert. "Aperto Networks has taken an important next step, in declaring specific plans for product delivery while preserving its proprietary technology and migrating its existing customer installations."  

Aperto will build its first generation of WiMAX Forum-certified systems with 802.16-compliant chips, leveraging more than five years of Aperto success in the delivery of dynamic TDMA MAC, QoS, RF technologies, networking software and systems in its first wave of certified 3.5 GHz frequency band systems, and moving quickly across the 2.5 GHz and 5 GHz bands.   At the 2004 Wireless Communications Association Conference in Washington DC next week, Aperto will unveil several new additions to its systems portfolio, all available now, including a new single-sector base station.
