Wireless cable TV transmitters consist of at least two parts, the first being a transmitter connected to the programming source that sends a signal containing the broadcast to one or more receivers attached to televisions. The transmitter is typically attached to either a cable television box or satellite dish receiver.
Some transmission units can be attached to multiple additional devices such as Blu-ray players or media streaming devices. The signal is broadcast to the remote receivers in a variety of frequencies and picture qualities. Signals can be standard or high-definition. Frequency ranges can be low, in the typical television broadcast range of 900 megahertz, or high, above 2.4 gigahertz, in the Wi-fi spectrum. The Frequency does not dictate the quality of the video, but it is important that the user not have multiple devices on the same frequency, which causes interference.
This type of television set-up is typically used in situations where wiring to the set's location is not feasible or aesthetically pleasing, or where the user has all of his media devices in a special room. In this manner, one set of source equipment can feed several viewing areas in a home or business. Radio frequency remote controls are generally used to allow users control of the channels and devices.
