I expect to see cellular phone transceivers built into residential phone systems in the U.S. within a year. A fixed directional antenna is installed to point to the nearest cell site and the controller is always on, allowing extensions instant access so multiple extension phones can share cellular access. This type of product is commonplace where there s little infrastructure, like China and parts of South America. Remember, the advantage of wireless services like broadcast TV is the lack of the huge infrastructure cost. If it is possible to broadcast information via RF reliably and reach a target audience, there is no contest.
Internet radios are now on the market.
These devices allow users to surf radio stations from around the world, and I give practical Internet TVs another five to eight years. Technology goes through cycles. The transition from a wired to a wireless service will likely evolve back to wired media. For example, as electronic filter CAD technology improves in the next decade, it will likely be possible to transmit analog information with just as much quality as digital information.
