VIVATO INTRODUCES NEW COMPLETE WI-FI SYSTEM TO FACILITATE LARGE SCALE WIRELESS NETWORKS
Bridge/Router Rounds Out Vivato's Wireless Local Area Networking System Solution

NETWORLD + INTEROP 2003, LAS VEGAS, NEV. - April 28, 2003 - Vivato™, a Wi-Fi infrastructure company, today revealed an enterprise-class Wi-Fi system solution that unifies the Vivato 2.4 GHz Indoor Wi-Fi Switch, the Vivato 2.4 GHz Outdoor Wi-Fi Switch, a new Vivato Wi-Fi Bridge/Router and the Vivato Vision management software. Vivato Wi-Fi System products have local intelligence that allows them to operate as stand-alone devices with complete management, security and Wi-Fi deployment tools; or as a cohesive system when used together. Vivato's Wi-Fi switches can already be managed in clusters of four; and now, Vivato has extended the Web-based management interface available on its Wi-Fi switches to allow a single console to manage very large Vivato systems with hundreds of devices.

The newest addition to the Vivato family of products is a Wi-Fi Bridge/Router designed to fill in coverage gaps, stretch the limits of range and provide an economical way to feed an outdoor wireless switch with backhaul from an in-building wired network.

"The evolution of Wi-Fi systems towards a truly switched model has the potential to accelerate adoption of wireless local area networks," said Pat Hurley, an analyst with TeleChoice, a marketing strategy consulting firm. "Large-scale Wi-Fi projects will benefit from networking systems that successfully package capacity, distance, management and security."

Designed to complement the existing Vivato 2.4 GHz switches, the new Vivato Wi-Fi Bridge/Router has two Wi-Fi ports, two 10/100 Ethernet ports and includes the functionality of a Wi-Fi Access Point as well as layer three routing capabilities. Typically, one of the Wi-Fi ports is configured to communicate to Vivato Wi-Fi switches using the 802.11 Wireless Distribution System (WDS) protocol; and the other Wi-Fi port provides coverage in the local area to standard Wi-Fi clients. Vivato Wi-Fi Bridge/Routers support a layer 2 mesh protocol based on WDS that allows them to communicate with each other to extend the reach of the Vivato Wi-Fi system. The Vivato Wi-Fi Bridge/Router can act as a repeater to fill coverage voids, or overcome line of sight issues to provide coverage to adjoining spaces outside the field of view of the Wi-Fi switches. It will be generally available in the third quarter of 2003. The recently announced Vivato 2.4 GHz Indoor Wi-Fi Switch and the Vivato 2.4 GHz Outdoor Wi-Fi Switch will begin shipping in May 2003.

"The Vivato Wi-Fi System leverages our software investment in the original Vivato Vision user interface on our switches to provide a unified way to manage and monitor many switches from a single console," said Ken Biba, Vivato CEO and Chairman. "The Vivato Wi-Fi Bridge/Router is a low-cost, complementary product to our core switches that furthers our strategy to enable Wi-Fi everywhere. It enables us to provide a cost-effective wireless networking solution that offers tremendous flexibility with unparalleled coverage and flexible capacity."

Note to Editors
