(MOBIle TEXt) A low-speed, packet-switched, wireless data network that operates in the U.S. at 8 Kbps in the 900 MHz band by Velocita Wireless. Mobitex was developed jointly by Ericsson and Swedish Telecom and first put to use in Sweden in 1986. It was later deployed in the U.S. and U.K. by RAM Mobile Data, a joint venture of RAM Broadcasting and BellSouth.

A Background of Notable Names
In 1998, BellSouth acquired all interest in RAM Mobile Data U.S. and changed its name to BellSouth Wireless Data. When BellSouth and SBC joined to create Cingular Wireless in 2000, the BellSouth Wireless/Mobitex division became Cingular Interactive. That unit was sold in 2004 to an investment company that changed the name to Velocita Wireless. See Velocita Wireless, DataTAC, CDPD and Ricochet.
