ARDIS Takes Lead in Fostering the Development of Wireless Applications Adds New Components to Wireless Software Developer Program; Program Provides Low-Cost ARDIS Air Time to Software Developers Building Wireless Applications.

LINCOLNSHIRE, Ill.--(BUSINESS WIRE)--June 14, 1995--ARDIS, the nation's first and largest two-way wireless data communications network, today announced the addition of several new features to its Wireless Software Developer Program that dramatically lower network air time costs for software applications providers. These new programs were unveiled at "The Future of Wireless Computing" conference, ARDIS' business partner event that opened today in Chicago and brings together leading hardware, software and services providers to discuss wireless solutions issues.

"The creation of innovative wireless applications is crucial to the expanded adoption of wireless communicators such as the Marco and Envoy from Motorola and the emerging availability of PC card wireless modems," said Rob Euler, senior vice president, Corporate Strategy and Regulatory Affairs at ARDIS. "Providing easy, cost-effective development support will strengthen the ARDIS position as the wireless data services carrier of choice for companies that are developing quality applications for mobile professionals."

Adding to its developer initiative that was announced in January, ARDIS has initiated a promotional pricing program for all software developers using ARDIS network air time for application development. The program, which is available now through the end of 1995, caps air time costs for developers at $40.00 per month per development hardware unit.

ARDIS has also established a rebate program to offset air time charges incurred by developers with applications that pass ARDIS certification testing. Level one of the rebate program, which certifies software applications as "ARDIS compatible," entitles developers to a 50 percent rebate on air time billed over the 24 months prior to application certification. To be "ARDIS compatible," applications must be able to transport messages end-to-end across the ARDIS network.

Level two of the rebate program provides companies with a 100 percent rebate on development air time costs, billed over the 24 months prior to certification, for applications certified by ARDIS as "efficient, reliable applications." Level two applications must be designed to take full advantage of the ARDIS messaging switch, perform data compression and include quality user documentation.

Among the software companies in the ARDIS developer program is Digital Objectives of Bound Brook, N.J., which specializes in healthcare applications and custom development services for the Apple Newton platform. Digital Objectives is currently working to ARDIS-enable its SirenPro family of professional software tools for emergency responders. With its application, emergency medical technicians are able to electronically complete medical and ambulance call reports, and other forms while in the field. With the ARDIS network, technicians will be able to transmit critical patient data wirelessly while on route to hospitals.

"Integrating with ARDIS wireless network services will enable us to advance SirenPro to another level, dramatically increasing its value to users and our company's strategic advantage," said Jerry Kaplan, vice president, Development at Digital Objectives. "Participating in the ARDIS developer program has well- positioned us to take advantage of the outstanding growth opportunities in wireless-enabled applications."

ARDIS operates the first and largest nationwide wireless data network enabling in-building and on-street data communications between hand-held terminals and host computers. The ARDIS network serves the top 410 metro areas in all 50 U.S. states, Puerto Rico and the Virgin Islands, and covers more than 80 percent of the population and 90 percent of the business activity in the United States. The service enables executives and mobile workers to access their corporate information systems and communicate instantaneously with their peers from virtually any location. -0-
