AT&T's McCaw Announces First Commercial Wireless Data Service For Tulsa, Oklahoma City and Salt Lake City; AirData Provides Remote Business Workers Access to Information Any Time, Anywhere; Unlike Cellular Voice, Data Charges Are Based on Volume, Not Minutes of Use.

KIRKLAND, Wash.--(BUSINESS WIRE)--July 17, 1995--The Wireless Data Division of AT&T's McCaw Cellular Communications Unit today announced availability of its AirDataSM Business Service, the first commercially available Cellular Digital Packet Data (CDPD) service in the Tulsa, Oklahoma City and Salt Lake City areas.

Across the country, AirData is now available to commercial customers in nine markets.

Developed by McCaw and the nation's largest cellular carriers, CDPD breaks data into packets and sends it over the existing cellular network. AirData empowers remote workers to access data any time and anywhere by utilizing this new wireless data technology designed to provide affordable, high-speed, reliable, secure and connectionless wireless communications.

AirData will change the way many mobile workers conduct business. For example, field-service and field-sales forces can improve productivity and customer satisfaction through convenient access to customer and company information. AirData is well suited for applications such as remote database access, remote host access, dispatch, data entry, point-of-sale verification, and messaging.

AirData helps businesses become more competitive by providing cost-effective access to information. Data moves quickly at 19.2 Kbps and, because charges are based on data volume, most businesses will incur monthly charges of less than $100 per user.

"With current wireless-data options, customers are conditioned to dial in, transmit data, disconnect, and work offline," said Kendra VanderMeulen, vice president and general manager of McCaw's Wireless Data Division. "Now, with AirData Business Service, they can afford to stay connected and use their applications interactively."

A groundswell of support has been felt in local markets as well. Oklahoma City has been following the progress of CDPD technology for its public safety programs and endorses it as a superior wireless technology. "The speed and security of CDPD technology are clear advantages when dealing with the public safety needs of a city," said Lucien Jones, technology support manager for the city of Oklahoma City. "From a management perspective, the nonproprietary nature and packetized billing structure make it ideal for multidepartment government uses. This technology would have helped Oklahoma City enormously during the recent bombing. CDPD access to our police and fire databases could have been set up quickly in our operational and investigative command posts."

In Salt Lake City, Intermountain Health Care Inc. has embraced the technology for a variety of health-care applications. Barry Bryson, technology development engineer, said, "McCaw's AirData is the optimum technology service to address important health-care needs. Speedy access to mission-critical information -- patient records, lab reports, reference materials -- will greatly improve a health-care worker's effectiveness."

CDPD gained recognition in the sports world by providing sports editors and World Wide Web browsers with instantaneous statistics at the Microsoft Grand Prix/USCF National Championship Road Race in Seattle last month. "We were excited to be able to use McCaw's AirData service to provide real-time race information from anywhere on the course without the constraint of wires," said David Allen, a technology coordinator for the bicycle race. "After using AirData, I was very impressed with CDPD's reliability, speed and efficiency in providing minute-to-minute race statistics."

In a separate announcement, Wireless Telecom Inc. (WTI), the nation's leading provider of mobile data network products and services, signed a master-agent agreement with McCaw's Wireless Data Division today to authorize WTI's qualified value-added dealers to sell AirData Business Service. "This announcement of additional service locations demonstrates McCaw's ongoing commitment to be the leading provider of CDPD service," said Rob Balgley, vice president of sales and marketing at WTI. "Our agreement with McCaw broadens both the range and quality of carrier service we are able to offer our network of resellers. McCaw has put a great deal of thought into how to develop the mobile data market, and we are pleased to be part of their plans."

Service was announced in Miami in April and in Dallas, Seattle, Minneapolis, Las Vegas and Portland, Ore., in June. Nationally, AirData will be available in more than 75 percent of McCaw's footprint by the end of the year. McCaw activated the nation's first CDPD network in November 1993 and is currently providing CDPD service in more than 50 pilots.
