Mobitex (Mobile text)

Low-speed, packet-switched wireless data networks deployed in Europe and

the United States alongside cellular radio networks. Developed jointly by Ericsson and Swedish Telecom, Mobitex offers runs in Europe in the 400–450 MHz band and in the United States in the 800 and 900

MHz bands, although it will run in any band. Mobitex channel spacing of 12.5 kHz supports theoretical data transmission rates of 8 kbps through Gaussian minimum-shift keying (GMSK) modulation. Mobitex packets are up to 512 octets, including overhead, using a slotted Aloha protocol. Mobitex networks support short message service (SMS), e-mail, and Internet access. See also cellular radio, channel, e-mail, GMSK, Internet, overhead, packet switch, protocol, slotted Aloha, and SMS.
