Mobile-Data Packet-Networks

The age of mobile data is upon us, and all indications point to a worldwide growth comparable to the rapid growth of cellular telephony. This paper provides an overview of mobile data options available to users, and provides a description of a specific mobile data option, the RAM Mobile Data, Inc. program. The Ericsson Mobitex packet switched mobile data system is now in operation in Scandinavia and Canada. RAM Mobile Data, Inc. is operating a growing national public Mobitex network in the U.S., and will soon be operating Mobitex networks in the U.K., and in other countries not yet announced. The system architecture is "open," and an interface specification is available which will permit any company to enter the mobile data business by providing mobile and portable radio/terminal equipment, and application software, to users of the RAM networks.
