I'm not quite understanding this, so I'll lay down some assumptions and describe how this is puzzling. Assumptions 1. cellular phones use digital signal. This is true of most areas. The switch was from analog to digital because digital gives much longer battery life (days compared to a couple hours). 2. DSL and cable internet are digital. Because internet is digital.... 3. DSL and cable have more bandwidth than cell phones. Anybody who has used their phone for their internet can support this one. Cell phones give good signal but they're crap compared to DSL and cable. 4. DSL and cable do not have enough bandwidth to play steady streaming videos. Have you noticed that when you try to play a video on the internet, you need to download (buffer) a lot of the video before you can start to play it since the playback rate is higher than your download rate? I can download at 160KB/s (that's bytes, not bits) and that's not nearly enough to play streaming video. problem If I can't play streaming video over my DSL connection, which has more bandwidth than a cell phone, how is it possible to watch TV on a phone?
