After conversion into the S-band and amplification, MBSAT uses its large antenna to sends the airwaves to all over Japan including the surrounding sea areas. To cover poor reception areas located behind tall buildings, etc, we are setting up gap-fillers. 8 Confidential & Proprietary LaunchLaunch ofof MobileMobile BroadcastingBroadcasting SatelliteSatellite ■March 13, 2004 At 2:41 p.m. Japan time, our Mobile Broadcasting Satellite (MBSAT) was launched from Cape Canaveral Air Force Station in Florida, the United States. The satellite separated successfully from its launch vehicle at 3:09 p.m. Then, it properly extended its north and south solar paddles (May 15) and its 12-meter antenna (May 29), and started routine operation in geostationary orbit. ■October 20, 2004 S-DMB Commercial broadcasting has started. ■March 24, 2008 Early Warning Earthquake Information Service has started as B to B service.

Currently, most of the poor reception areas are tunnels. By setting up gap fillers, we are now preparing reception environments in tunnels. 22 Confidential & Proprietary Wide Range Gap-Filler (Ground-Based Re-transmitter) We use the following types of gap-fillers as appropriate: Wide range (areas of 1 to 3km in radius) Short range (spots of 500m in radius) Weak (indoors using S-S repeaters) 100cm antenna gain : Approx.15dBi 10cmφ×100cm 1~3 Sectors Signal processor S-band transmitting antenna 7 Confidential & Proprietary S-DMB reception now available inside tunnels Gap fillers installed in expressway tunnels As authorized by the Japan Highway Public Corporation (JH), Mobile Broadcasting Corporation has installed retransmitting devices, or gap fillers (GFs), inside tunnels on the Tohmei Expressway in order to make reception of S-DMB broadcast signals possible inside these tunnels. These gap fillers will make it possible for drivers to enjoy MobaHO! broadcasts inside these tunnels, without interruption.
