 TV. Any/all of the broadcast options are capable of triggering uplink bandwidth value. So we are interested in the performance of the receiver in terms of sensitivity, application bandwidth and power efficiency and the performance of the receiver in the presence of locally generated transmit power (the return channel). We should also remember that we can also deliver radio and TV channels over existing cellular radio bandwidth. This means that our choice of broadcast receivers could include existing analogue AM or FM radio, digital AM (DRM or equivalent), DAB/DMB, DVB-T or HSPA or EVDO mobile broadband products. Up until 2010 there was the additional option in the US of a system optimised for mobile reception known as Media FLO (forward link only) developed and promoted by Qualcom and an equivalent version of DVB T known as DVB H (handheld). Terrestrial Broadcast/Cellular Network Integration Both these systems were vigorously promoted from 2005 and both failed for reasons we need to examine. A number of phones included and still include integrated FM tuners. These work as well as most FM tuners when used in mobile applications, that is quite well sometimes but not consistently well in weak-signal or high-mobility conditions. There is nothing wrong in principle in adding digital subcarriers to existing analogue bandwidth and using these carriers for data and image transmission - an analogue and digital multiplex. This provided a perfectly adequate basis for first-generation 'visual radio' systems, for example in Finland. 8 In practice, over the longer term, it should be possible to get better bandwidth and power efficiency and a more consistent user experience from a digital broadcast receiver. The same applies for analogue AM systems. All of the digital broadcast systems should in theory and generally in practice provide a performance benefit in terms of quality, consistency and bandwidth and power efficiency. DRM would be (relatively) easy to integrate into present cellular handset form factors and dongle produ
