ellular connectivity Extended battery life Power saving through a packet based system; receiver only 'on' around 10 % of the time Seamless Viewer Experience Soft handover; seamless switching between transmitters Scalability DVB-H interleaves allow the network to be scaled DVB-H network scales according to the number of users Open Standards Equal access to technology (ETSI) DVB-T compatibility (same physical layer, modulators and transmitters) Throughput DVB-H has largest output capacity of broadcasting technologies up to 11 Mbps Reception/Coverage Spectrum band: 470-702 MHz Bandwidth: 8, 7, 6 or 5 MHz Integrated antenna Indoor reception support Large area coverage Flexibility for Mobile Broadcast Networks Single antenna in medium to large SFNs Many different capacity alternatives and cell sizes The positioning IP datacasting over DVB-H and other broadcast technologies is summarised in Table C.2. Digital Video Broadcasting Table C.2 Technology comparison (DBM, digital multimedia broadcasting, ISDB-T, terrestrial integrated services digital broadcasting) Mobility Data rate Frequency band Comments DVB-H 5-31 Mbps; UHF (470-702 MHz) typical 10 Mbps Maximium 1.15 Mbps VHF antenna size?

It is scalable with a cell size up to 100 km (DVB-H cell size is smaller) with a huge capacity of 54 channels each with 5-32 Mbps. Developed for MPEG-2 (Moving Picture Experts Group 2) stream distribution, it can basically carry any data,
