Digital Video Broadcasting for Handhelds (DVB-H)
As subscriber numbers soar, 3G networks won´t have the capacity to han- dle mobile TV. To combat the data snarl, handset manufacturers are adding a TV-dedicated antenna to phones, such as the N92; and a company called Crown Castle Mobile Media is putting up DVB-H transmitters across the country.

4G Networks

At 1 gigabit per second, 4G networks will broadcast in high-def. To maximize network space, stations will be streamed over a dedicated section of bandwidth (the way cable TV is), or beamed on demand. Slim, single-antenna phones, like this touchscreen concept, will be able to receive
location-based news from local network servers.
