Frost & Sullivan Commends Sarian Systems' Product Innovation in High Speed Wireless Enterprise Routers

Business Wire, August 6, 2008

LONDON -- The 2008 Frost & Sullivan European High Speed Wireless Enterprise Routers Product Innovation of the Year Award is presented to UK-based Sarian Systems, A Digi International Inc. Company, in recognition of its HR series routers. The addition of High-Speed Uplink Packet Access (HSUPA) capability to Sarian's enterprise HR routers is a novel approach that offers high speed uplink data transfer rates on par with fixed-line broadband. This allows companies to transfer larger volumes of data at speeds far superior to previously employed mobile networks.

HR routers are enterprise class routers developed by Sarian Systems to provide 'super 3G' high speed mobile access by employing advanced technologies such as HSUPA and HSDPA. The HR4110 router and HR4420 multi-router are both compatible with mobile technologies such as GPRS, EDGE, UMTS, HSDPA and HSUPA.

"This allows enterprises to run bandwidth hungry applications and services over mobile connections in a cost-effective fashion, while also enabling a smooth migration path from GPRS, EDGE, and UMTS/3G networks to HSUPA and HSDPA," notes Frost & Sullivan Industry Analyst Venkat Malleypulla. "Since their launch, HR routers have been widely used in various sectors such as surveillance, media streaming, and remote digital signage."

Adding HSUPA to the products has aided diverse application sectors, including surveillance, which requires captured images to be transmitted in real time. The HSUPA capabilities of the HR router enable it to provide an uplink of up to 2 Mbps, thereby facilitating high quality live streaming CCTV coverage.

"This ability will assist organisations in enhancing their security surveillance even in the most remote locations which would not be possible with traditional wired networks," remarks Malleypulla. "Furthermore, the HSUPA capability could be used to carry out VoIP and video-conferencing for companies and the router can be extended to provide high-speed data communications for over 100 users, unlike the earlier HSDPA router which provides the same service for only a limited number of users."

Since this device is suitable for both high speed downloads and uploads, it provides an excellent opportunity for companies to stay online and on par with fixed-line networks. Since this router offers the same reliability as wired routers or an ADSL connection, it could also act as a reliable network back up in the event of a fixed-line network crisis.

"Sarian Systems has designed its HR routers that feature dual SIM cards slots to allow customers to pick the secondary wireless network of their choice," states Malleypulla. "During a primary network crisis, it would provide reliability in mission critical applications as it offers access to secondary wireless networks in a cost-effective manner."

The company is currently working with Fujitsu to supply similar wireless back-up technology integrated with wired broadband ADSL for a major national infrastructure project - estimated to be worth about $10 million - in the United Kingdom. Notably, the worth of this deal is equivalent to Sarian System's turnover last year. The company also has strong ties with Motorola and Novatel in the U.S. and Option N.V in Belgium with regard to the development of wireless technologies.

The Frost & Sullivan Award for Product Innovation is presented each year to the company that has demonstrated excellence in new products and technologies within its industry. The recipient company has shown innovation by launching a broad line of emerging products and technologies.

Frost & Sullivan Best Practices Awards recognise companies in a variety of regional and global markets for demonstrating outstanding achievement and superior performance in areas such as leadership, technological innovation, customer service, and strategic product development. Industry analysts compare market participants and measure performance through in-depth interviews, analysis, and extensive secondary research in order to identify best practices in the industry.
