2. Integrated reception system - Wikipedia

   en.wikipedia.org/wiki/Integrated_reception_system

   An integrated reception system (IRS) provides broadcast signals from multiple sources (typically terrestrial television, FM radio, DAB digital radio and satellite TV) to multiple outlets, via a single aerial cluster and signal booster-distributor. The most obvious use for such a system is in communal housing blocks, where one aerial cluster can ...

3. FM transmitter (personal device) - Wikipedia

   en.wikipedia.org/wiki/FM_transmitter_(personal...

   A personal FM transmitter is a low-power FM radio transmitter that broadcasts a signal from a portable audio device (such as an MP3 player or a smartphone) to a standard FM radio. Most of these transmitters plug into the device's headphone jack and then broadcast the signal over an FM broadcast band frequency, so that it can be picked up by any ...

4. Antenna diversity - Wikipedia

   en.wikipedia.org/wiki/Antenna_diversity

   A well-known practical application of diversity reception is in wireless microphones, and in similar electronic devices such as wireless guitar systems. A wireless microphone with a non-diversity receiver (a receiver having only one antenna) is prone to random drop-outs, fades, noise , or other interference , especially if the transmitter (the ...

5. FM broadcasting - Wikipedia

6. Signal strength in telecommunications - Wikipedia

   en.wikipedia.org/wiki/Signal_strength_in...

   In telecommunications, [1] particularly in radio frequency engineering, signal strength refers to the transmitter power output as received by a reference antenna at a distance from the transmitting antenna. High-powered transmissions, such as those used in broadcasting, are expressed in dB-millivolts per metre (dBmV/m).

7. Broadcast range - Wikipedia

   en.wikipedia.org/wiki/Broadcast_range

   Technologies are available that allow for switching to a different signal carrying the same radio program when leaving the broadcast range of a station. Radio Data System allows for switching to a different FM or station with the same identifier, or even to (but not necessarily from) an AM station. Satellite radio also is designed to switch ...
