ADVISORY...for Thursday (Nov. 6)

Next Generation Networks 2003

MILPITAS, Calif.--(BUSINESS WIRE)--Oct. 30, 2003

Aperto Networks, a leading provider of new generation scalable broadband wireless access systems, will speak at an invited session at the annual Next Generation Networks conference, http://www.bcr.com/ngn/default.asp, held at the Marriott Copley Place in Boston from November 3 to 7, 2003.

When: Thursday, November 6, 2003; 1:30pm-2:45pm

Where: Marriott Copley Place in Boston

Who: Dr. Reza Ahy is president, CEO and chairman of Aperto Networks

What: Panel -- The First Mile: Alternative Broadband Technologies and
    Deployments

Aperto Presentation: Wireless MANs (WiMAX) for Multiple Services in
    Next Generation Networks

Moderated by industry expert Dave Passmore, Research Director, Burton Group and Co-chair of NGN2003, the panel will feature Dr. Ahy's presentation on the ability of IP-based, QoS-powered, Wireless Metropolitan Area Networks to enable multiple services over a single unified broadband infrastructure, and the implications of the WiMAX Forum-enabled wave of standardization forecasted to occur in 2004.

Today's wireless MANs are capable of delivering 20 Mbps over the air interface to each user, thus enabling multi-tier data connectivity with different classes of service, as well as voice and video. They are rapidly moving toward standardization through the recently ratified IEEE 802.16 global standard, and will thus ride an improving cost curve and the benefits of end-to-end network interoperability. With bandwidth and dynamic traffic flow requirements increasing, wireless MANs must support even greater demands for class-of-service and feature differentiation, as compared to more traditional infrastructure solutions such as DSL, cable and T1/E1. Rapidly-deployable Wireless MANs are also becoming the preferred solution for Wi-Fi Hotspot backhaul in terms of capacity, coverage and economics.

Dr. Ahy will address the recently ratified IEEE 802.16 global standard, the wireless MAN complement to the highly-successful IEEE 802.11 standard for wireless LAN networks. The interoperability and certification body known as the WiMAX Forum is now supported by nearly 50 of the top wireless MAN vendors and carriers, whose efforts will be an integral part of IP-based next generation wireless networks empowering multiple broadband services.
