S-DMB

S-DMB (Satellite-DMB) is a hybrid version of the Digital Multimedia Broadcasting. The S-DMB uses the S band (2170-2200 MHz) of IMT-2000. and delivers around 18 channels at 128 kbit/s in 15 MHz. It incorporates a high power geostationary satellite, the MBSat 1. For outdoor and light indoor coverage is integrated with a terrestrial repeater (low power gap-filler) network for indoor coverage in urban areas.

A similar architecture is also used in XM Satellite Radio, Sirius Satellite Radio, DVB-SH and ETSI Satellite Digital Radio (SDR).

S-DMB deployment

On May 1, 2005 South Korea became the first country in the world to start S-DMB service. The service provider was TU Media, subsidiary of SK Telecom. The same satellite and system was used in Japan on the defunct MobaHo! service (2004–2009) of Mobile Broadcasting Corporation (MBCO).
