Satellite Digital Radio (SDR) is an activity of the standardisation organisation ETSI. The European Telecommunications Standards Institute (ETSI) is a standardization organization of the telecommunications industry (equipment makers and network operators) in Europe, with worldwide projection. ...
It addresses broadcast systems where a satellite transmits directly to mobile and handheld receivers and is complemented by terrestrial transmitters. The transmitted content comprises audio broadcast, mobile TV, text and graphical information, as well as off-line content. The satellite component allows geographical coverage at low cost, whereas the terrestrial component improves reception quality in built up areas. This does not cite its references or sources. ...
ETSI SDR standards allow to implement parts of such networks in an interoperable way. ETSI has so far standardised the physical layer of the air interface (radio interface). This allows to implement demodulators in integrated circuits. The physical layer is described by the following set of standards:
- "Satellite Earth Stations and Systems (SES); Satellite Digital Radio (SDR) Systems; Outer Physical Layer of the Radio Interface"
- "Satellite Earth Stations and Systems (SES); Satellite Digital Radio (SDR) Systems; Inner Physical Layer of the Radio Interface;
Part 1: Single Carrier Transmission" - "Satellite Earth Stations and Systems (SES); Satellite Digital Radio (SDR) Systems; Inner Physical Layer of the Radio Interface;
Part 2: Multiple Carrier Transmission" All ETSI specifications are open standards available at ETSI Publications Download Area (this will open ETSI document search engine; free registration is required to download PDF files). Open standards are publicly available documents that contain implementable specifications. ...
WorldSpace will use ETSI SDR in its new network covering Europe from 2008. Also Ondas has announced to use ETSI SDR. WorldSpaces AfriStar control center in Washington, D.C. WorldSpace is the worlds first digital satellite radio network. ...
The DVB-SH specifications, which the DVB Project has created, target similar broadcast systems as ETSI SDR. DVB-H (Digital Video Broadcasting - Handheld) is a technical specification for bringing broadcast services to handheld receivers. ...
