Milpitas, CA, September 10, 2001 - Aperto Networks, a leading developer of second-generation fixed broadband wireless access systems, has received regulatory approval of its end-to-end PacketWave™ multiservice platform from the U.S. Federal Communications Commission and the Canadian regulatory authority, Industry Canada.

The North American approvals complete the regulatory process required to begin revenue shipments. Aperto has already obtained regulatory approval in selected overseas markets where licensed or license-free 5.8 GHz spectrum is readily available, clearing the way for Aperto to ship systems to global service providers.

“Achieving these milestones is the final step in readying our systems for commercial shipment,” stated Alan Menezes, Aperto’s vice president of marketing. “Our scalable, point-to-multipoint PacketWave systems have been field-proven in customer trials since January 2001, and are now ready for revenue generating services.”

“These regulatory approvals come at a critical time for carriers expanding their broadband service footprint,” said Peter Jarich, Strategis Group's director of global broadband research.“ "Carriers now need multiple options for multiservice delivery to customers. The momentum Aperto is setting in the fixed broadband wireless access sector is more urgent than ever in today's environment."

Aperto's PacketWave solution uses a common platform across all spectrum bands. The systems operate in the 2.5 (MMDS), 3.5 (FWA), 5.3 and 5.8 (UNII) GHz frequency bands. The newly introduced 5 GHz radio solution will be complemented by radios supporting the additional frequencies in Q4 2001. This family of radios allows service providers to operate simultaneously in multiple frequencies on the same equipment, and gives wireless operators investment protection while maintaining flexibility for future deployments across multiple markets.
