Why isn't there Wireless television?

There is a very large difference between a TV receiver and a radio or cell phone. The radio and the cell phone need to receive only one very narrow-band frequency. The TV needs to be capable of enormous bandwidth in order to capture and make use of all the data that forms video in color. It's like the difference between a bucket of sand and an entire beach.

For that reason, a TV needs a large, very sensitive antenna compared to the radio or cell phone, or it needs a tremendously broadband input source like coaxial cable or a satellite downlink.

Wireless TV transmission in the home does exist to a limited extent. You can connect an RF modulator like the example below to a cable or satellite box and broadcast it to the TVs throughout your home. However, those TVs will not be able to change channels--they're limited to whatever channel the RF modulator is receiving from your cable/satellite box. And the signal is only analog.

I hate to tell you this, but TV is wireless; that's the purpose of the antenna.

Radios are wireless, they use an antenna, the same thing with wireless Internet, the antennas are usually built into the device, but they are still there.

If the signals are strong enough you can use "rabbit ears" on a portable TV and move it around, too.

Reading a good e book provides a richer experience and can leave you with memories that will last years. Television is merely educational if you're observing a documentary or something similar

I have enjoyed to learn always. But I'd be lying easily said I didn't also enjoy TV. During the day this is a publication usually.
