Mobitex is an OSI based open standard, national public access wireless packet-switched data network.
Mobitex puts great emphasis on safety and reliability with its use by military, police, firefighters and ambulance services.
The modulation scheme used is GMSK with a slotted aloha protocol at 8000 bit/s, although user throughput is typically around half of that.
The network provided the first public access wireless data communication services in North America.
Nearly all breakdowns to Green Flag UK service agents were sent using Turbo Dispatch, a Mobitex-based gateway software developed in the early nineties by Ian Lane and Andy Lambert.
Despite the competitive nature of the vehicle recovery market in the UK, motoring organisations were persuaded to co-operate and make a standard of the format.
