Mobitex Network Design

Mobitex is an OSI based open standard, national public access wireless data network first introduced in 1991 by carriers RAM Mobile Data and in Canada 1990 by Rogers Cantel. Developed by Ericsson, Mobitex puts great emphasis on safety and reliability with its use by military, police, firefighters and ambulance services. During 9/11 and the 2005 Hurricane rescue and clean up operations, Mobitex proved itself to be a very reliable and useful system for first responders. In the mid '90s Mobitex gained consumer popularity by providing two-way paging network services. It was the first wireless network to provide always on, wireless push email services such as RadioMail and Inter@ctive Paging. It is also used by the first model of Research in Motion's BlackBerry, and PDAs such as the Palm VII.

Mobitex is a packet-switched, narrowband, data-only technology mainly for short burst data. Mobitex channels are 12.5 kHz wide. In North America, Mobitex runs at 900 MHz, while in Europe it used 400-450 MHz. The modulation scheme used is GMSK with a slotted aloha protocol at 8000 bits/s, although user throughput is typically around half of that. In computer networking and telecommunications, packet switching is a communications paradigm in which packets (messages or fragments of messages) are individually routed between nodes, with no previously established communication path. ... Narrowband (narrow bandwidth) refers to a signal which occupies only a small amount of space on the radio spectrum -- the opposite of broadband or wideband. ... Modulation is the process of varying a carrier signal, typically a sinusoidal signal, in order to use that signal to convey information. ... Gaussian minimum shift keying or GMSK is a kind of continuous phase modulation. ... ALOHAnet was a pioneering computer networking system developed at the University of Hawaii. ... In the field of telecommunications, a communications protocol is the set of standard rules for data representation, signalling, authentication, and error detection required to send information over a communications channel. ...
