                                  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

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.
