SAN JOSE, Calif.--(BUSINESS WIRE)--March 15, 2002

Aeris.net, the leading network provider for wireless telemetry messaging, announced today its completion of North America-wide coverage with the addition of MicroBurst service in key NAFTA corridor markets -- Dallas, San Antonio, and Oklahoma City. The MicroBurst network is now available across all of North America, from northern Alberta, Canada through the southern regions of Mexico, wherever cellular coverage exists.

"Aeris's North America-wide network coverage is essential to the successful deployment of our customers' commercial applications," stated Dick Gossen, president and CEO of Aeris.net. "Aeris's expansion in the NAFTA corridor completes our North American coverage footprint. The market for machine-to-machine communications (M2M) -- wireless telemetry and data telematics -- is taking off. For businesses, wireless monitoring and tracking of key assets is adding value to billions of dollars in capital investments in transportation, energy and communications. For consumers, wireless telemetry and tracking provides enhanced security and convenience for homes and vehicles."

For mobile customers of Aeris, the addition of the Dallas, San Antonio, and Oklahoma City markets is particularly significant to facilitate international trade between the U.S. and Mexico. Texas leads the nation in exports to Mexico, with more than 80% of overland trade traveling through Dallas. "The NAFTA corridor is an extremely important market for many of our customers," stated Dave Ladner, general manager of PeopleNet Communications. "The expanded coverage offered by Aeris gives PeopleNet customers a competitive edge in the these markets through the use of low cost, high quality communications capabilities that allows them to more effectively track and locate their vehicles and drivers."

Non-mobile customers -- like the providers of security system monitoring services -- also benefit from the expanded coverage. "We selected MicroBurst because it provided us with an extensive, low-cost, highly reliable network to help grow our business," commented Ivar Bazzy, vice president of AlarmNet, the largest provider of wireless monitoring of security systems and a member of the ADEMCO Group, which is part of Honeywell Security & Fire Solutions. "With the addition of these important markets in Texas and Oklahoma, the broad coverage of the MicroBurst network now allows us to ship our monitoring products through our extensive distribution channels and install them in any market in North America. That's not something we could do with any other wireless network."

How MicroBurst Works

MicroBurst technology is a proprietary utility that enables short data packets to be transmitted over control channels in cellular networks using standard IS-41C signaling mechanisms. These short data packets are transmitted by cellular devices and are routed to the Aeris central hub facility over SS7 (Signaling System 7) networks. The Aeris hub routes the data for delivery to the application via one of several available transports, which include Internet, dial-up and dedicated connectivity.
