S-DMB (Satellite-DMB) was a hybrid version of the Digital Multimedia Broadcasting. The S-DMB used the S band (2170-2200 MHz) of IMT-2000. and delivered around 18 channels at 128 kbit/s in 15 MHz. It incorporated a high power geostationary satellite, the MBSat 1 (since 2013, sold to Asia Broadcasting Satellite (ABS) of China). 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).
