Also attached, as examples of some of the products included in the AirAware family, are data sheets for AirVU(TM) TRIPS, AirVU TN3270, AirVU TN5250 and AirVU ANSI VT-220. 4 [TELXON LOGO] - -------------------------------------------------------------------------------- NEWS RELEASE FOR IMMEDIATE RELEASE TELXON INTRODUCES NEW FAMILY OF WIRELESS COMMUNICATIONS SOFTWARE NOVEMBER 4, 1997 - - CHICAGO, ILLINOIS - - A dynamic new wireless communication software product line called AirAware(TM), was introduced at Scan-Tech 97 by Telxon Corporation, a world leader in wireless and mobile computing technologies. Designed to provide the framework for streamlining the movement of data in the rapidly expanding world of mobile information, the AirAware software family is the first to provide users with options in system architecture. One AirAware module, the AirVu(TM) product line, utilizes open system standards to enable direct connection of mobile clients to the enterprise. Another module, AirGate(TM), uses an application server as the gateway to the enterprise and is based on contemporary three tier client-server architecture. The AirGate server software is available for UNIX(R), Windowsr NT(TM), HP-UX, AIX, AS/400 and Sun Solaris(R) platforms and can support up to 1,000 clients. The third currently available module is the innovative AirBeam(TM) for software distribution and version control. AirBeam allows the dynamic configuration of mobile computers and application loading from the server. Additional AirAware modules currently under development include AirVision(TM), for SNMP based network management, and AirXon(TM), for remote diagnostics and administrative services. "AirAware is the mobile systems software for the next millennium," said Dave Loadman, chief technical officer for Telxon Corporation. "It allows for seamless and transparent mobile connectivity to existing applications without requiring extensive modifications to those applications." "In operation", Loadman said, "the AirGate application server is inserted between multiple data sources on the enterprise network and the client, who communicates only with the server. The server then interacts with the enterprise systems on behalf of the mobile client and the majority of the message traffic occurs over a high speed Telxon Corporation/Corporate Communications Department 3330 West Market Street/P.O. Box 5582/Akron, Ohio 44334-0582/800-800-8001/ Fax (330) 664-2058 5 enterprise network, instead of the slower or more costly mobile connection. Communication traffic is thus optimized for maximum RF performance. Loadman said the AirAware family of mobile information system software was designed to minimize the customer's total cost of RF system ownership. "With AirGate the requirements for mobile information processing capabilities are minimized, reducing mobile computing hardware costs," Loadman explained. "The useful life of mobile devices is also extended. Any expansion of memory and CPU capabilities needed to support evolving applications can be isolated to the server. "With AirBeam, the software maintenance and distribution is also greatly simplified," Loadman said, "because software revisions need only be distributed to the server, and AirBeam will automatically handle any required distribution and upgrades to the mobile clients." The launching of AirAware represents the evolution of Telxon's innovative Gateway Connectivity Systems(TM) software to the open server environment. Planned future enhancements will support wide area network, remote and batch communications. "The bottom line for AirAware is that it reduces the total cost of ownership and minimizes the risk of obsolescence," Loadman said. Designed to be used today, AirAware is also Year 2000 compliant. Telxon Corporation is a leading global designer and manufacturer of wireless and mobile information systems for vertical markets. The company integrates advanced mobile computing and wireless data communication technology with a wide array of peripherals, application specific software and global customer service for its customers in more than 60 countries around the world.
