NETWORLD + INTEROP 2003, LAS VEGAS, NEV. - April 28, 2003 - Vivato™, a Wi-Fi infrastructure company, and Vivato's value added distributor TerraWave Solutions, announced today at Networld+Interop 2003 the availability of a two-day, instructor led course to certify networking professionals and resellers to sell, design, install and support Vivato's Wi-Fi System.

The Vivato Wi-Fi System includes the Vivato 2.4 GHz Indoor Wi-Fi Switch, the Vivato 2.4 GHz Outdoor Wi-Fi Switch, the new Vivato Wi-Fi Bridge/Router announced today by Vivato and the Vivato Vision management software.

The Wi-Fi System training classes developed by GigaWave Technologies, the educational division of TerraWave Solutions, will be offered at its San Antonio, Texas learning center in late May 2003. Registration for the training is currently available at www.giga-wave.com or by calling (210) 375-0085.

"Vivato is a clear example of how quickly Wi-Fi technologies are evolving and changing our conventional view of wireless networking, "said Chris Marco, President of
TerraWave Solutions. "Professional training on leading-edge wireless networking technologies is crucial to any organization's ability to successfully deploy, secure and manage a wireless infrastructure. We're excited to be able to offer Vivato's extraordinary products to resellers, as well as to help educate and facilitate cutting-edge Wi-Fi concepts that are changing the way wireless networks will be deployed in the future."

Vivato's Wi-Fi System offers dramatic range and capacity and a new, cost-effective architecture for deploying Wi-Fi local area networks. The Vivato Wi-Fi System, like its
Ethernet switching counterpart, has centralized management and distributed intelligence with standards-based network interoperability, and integrated security management and access control. The Vivato Wi-Fi System supports standard 802.11b Wi-Fi clients and integrates with existing wired network systems.

"Wi-Fi switching is really a new way of thinking about wireless networking and we are confident that TerraWave Solutions' wireless experience and training services will help Vivato's reseller partners realize the potential of this revolutionary technology," said Ken Biba, Vivato CEO and Chairman. "Vivato's switches will be sold through an exclusive distribution channel of certified resellers and this training is a key element of the certification process."

During the Vivato Wi-Fi Switching training, students will learn the differences between conventional Wi-Fi technology and Vivato's Wi-Fi revolutionary wireless switch and will focus on learning about the Vivato switch technology, product capabilities and features, and how to install, configure and secure the Vivato switch. The curriculum has been developed for technical engineers, network integrators and technical sales personnel who need to know how to sell, design, install and support wireless networks.
