Radio broadcasting systems; System for Wireless Infotainment Forwarding and Teledistribution (SWIFT)

Scope

This European Telecommunication Standard (ETS) establishes a broadcasting standard of a System for Wireless Infotainment Forwarding and Teledistribution (SWIFT) designed for delivery of data services for mobile, portable and fixed receivers in the FM band. This ETS defines the nature and content of the transmitted SWIFT signal. It describes also the organization of the multiplex for the SWIFT standard. A multiplex is necessary to optimize the use of the radio channel by sharing it between several applications. For example, a dGPS application has some precise constraints such as real time (one message per second), size (2 kbits per message). This application requires a continuous channel of perhaps 3 kbit/s. Assuming a DARC channel has a minimum useful bit rate of 6 kbit/s, it would be interesting to use the remaining 3 kbit/s for an other application, newspapers broadcasting for example.
