Mobitex connectivity

Mobile data networks, of which Mobitex is an example, are seen as integrated parts of a company´s or organisation´s data solution. A typical situation is that a mobile data network has to interact with more traditional messaging services like SMS (short message service) in GSM and paging networks, while at the same time providing gateway services to land based PSDNs (packet switched data networks). Mobitex is a packet switched data only network based on an RF cell structure similar to that of a mobile telephone network. A local Mobitex network, covering a country or another administrative geographical area, can comprise one or more Mobitex subnets connected via an IP backbone.
