Trapeze Networks Awarded Two Breakthrough Patents

Wednesday, April 22, 2009

New Intellectual Property Covers NonStop Wireless Networking, Energy Conservation

Pleasanton, CA -- The United States Patent Office has awarded Trapeze Networks (NYSE: BDC) two breakthrough wireless networking patents. The patents advance the company's position in NonStop Wireless networking and cover technologies that allow organizations to deploy and manage access points more easily and at lower costs.

"The award of these two new patents builds and reinforces Trapeze Networks' position as an innovator and leader in wireless networking," said Ahmet Tuncay, chief technology officer of Trapeze Networks. "We are delivering inventions that are solving real customer problems and driving the adoption of wireless networking around the world."

Foundational Patent Builds on NonStop Wireless Networking

The "System and Method for Distributing Keys in a Wireless Network" (U.S. Patent 7,529,925) is a foundational patent that relates to improvements in roaming performance. This invention covers the fundamental operations of pairwise master key (PMK) caching, the way to maintain security when clients roam from one access point to another. The invention allows the distribution of key information about client devices between access points such that clients can avoid re-negotiation of new keys with new access points as they physically move in a wireless network. This results in uninterrupted wireless service and superior quality of connection. Most of today's enterprise class wireless LANs that support high-quality voice over IP services require PMK caching features in order to provide rapid roaming between access points and eliminating dropped calls.

"Power-Aware Multi-Circuit System and Method" (U.S. Patent 7,525,215) is an invention that allows access points to use one or more types of power sources (IEEE 802.1at, IEEE 802.3af, or proprietary PoE) and adjust the functionality of the access point based on the level of power available to it. This invention simplifies installation and operation of access points on existing networks and allows businesses to entirely avoid installing expensive additional power mains, new PoE sourcing devices, and upgrading their wiring closets to support the wireless network.

NonStop Wireless Networking: Wired Reliability + Total Mobility

NonStop Wireless brings painless, fully automated dynamic redundancy and scaling to wireless LANs. NonStop Wireless technology allows for non-stop operation, in-service upgrades, and hitless failover while dramatically simplifying redundancy configuration. Trapeze's NonStop Wireless dramatically reduces capital equipment and ongoing IT operational costs associated with building, maintaining, and growing high-availability resilient wireless LANs.

NonStop Wireless is delivered through Trapeze Mobility System Software (MSS). MSS is the distributed wireless operating system that runs on Trapeze's wireless LAN equipment and delivers the benefits of Trapeze's Smart Mobile architecture. MSS runs on all Trapeze equipment, from access points to controllers and is backwards compatible across the company's entire product line.
