Tokyo, Japan and Tel-Aviv, Israel, July 18, 2007 – Sumitomo Densetsu, a leading integrator of Information and Communications Technologies (ICT), and Extricom, the designer and manufacturer of the Interference-Free™ Wireless LAN System, today announced a distribution partnership. With this agreement, Sumitomo will be able to offer complete, end-to-end enterprise solutions spanning wired, wireless, passive and active networking infrastructure.

For over twenty years, Sumitomo Densetsu has been at the forefront of the Japanese market in the design, deployment, and management of advanced information networks. The addition of the Extricom solution enables Sumitomo Densetsu to extend this leadership by providing a truly unique WLAN solution for advanced mobility applications such as voice, video, location-based services, as well as pervasive data connectivity.

Extricom's patented Interference-Free WLAN System represents the next generation of enterprise Wi-Fi, with a fundamental shift in architecture from "cell-planning" to a "channel blanket" topology. This innovative approach eliminates the co-channel interference that plagues traditional WLAN systems, to deliver seamless and zero-latency mobility, robust, "wire-like" client connections, greatly increased capacity, and the ability to design for a guaranteed and predictable level of service for all users. All this is achieved without the iterative and costly RF cell-planning required in traditional solutions. The result is a high-performance yet simple WLAN for the enterprise triple play of data, voice (VoWLAN), and video.

This agreement will provide Extricom with greatly expanded commercial reach in Japan, as well as the outlet to expand recognition for its brand and unique WLAN system. Customers are demanding that their wireless infrastructure support all services, everywhere, for everyone, with the same predictability of performance they take for granted in the wired world. Sumitomo's market leadership in infrastructure solutions, combined with Extricom's innovative enterprise WLAN, will enable those customers to attain the full benefit of the next wave of wireless applications such as voice over Wi-Fi and location-based services.
