ration 15.19 Summary The proximity of cellular receive and transmit bands at 700 and 800 MHz to UHF broadcast TV channels opens up the possibility of supporting digital TV transmission via cellular base stations and digital TV reception in handsets and mobile broadband devices without significant additional hardware cost. Rebroadcasting of national and local TV from cellular transmitters would allow HDTV to be delivered to portable receivers without the need to connect portable devices to a fixed antenna. Cellular site and hardware costs including backhaul overheads could be amortised across cellular and broadcast services. There would be no need to ring fence or repurpose TDD bandwidth at 2 GHz for broadcasting. These channels could be used as originally intended for mobile broadband access. The coupling of local and national linear TV broadcasting with mobile broadband would unlock new direct and indirect revenue streams both for the broadcasters and cellular operators and would provide the basis for developing innovative mass-market consumer electronic products that could be clearly differentiated from present product and service offerings. The combination of the additional revenues realisable from a more broadly based user experience combined with more broadly amortised costs could significantly improve profitability for all involved parties. 15.20 TV or not TV - That is the Question - What is the Answer? The launch of Apple's iPad has generated countless column inches of industry comment but no one seems to have quite nailed the answer as to what users will do with the device. The consensus seems to be that iPads will change the way that media is consumed and information is accessed on the move. However, the form factor of the device, smaller than a lap top but larger than a smart phone, suggests a sit-down or sit-back experience - very different from how mobile phones are used today. If this is true, then some form of TV connectivity would seem sensible. This could be IPTV over WiFi or cellular but equally
