.BONJOUR ‼️
Actually all the remotes work on EMR i.e electro magnetic radiàtion
most of the remotes use IR i.e infrared radiation to control and very few which work for a longer distances use U.V radiation to control the devices
hope it helps

How remote work
Answer
Infrared light is in the invisible portion of the electromagnetic spectrum. An IR remote control (the transmitter) sends out pulses of infrared light that represent specific binary codes. These binary codes correspond to commands, such as Power On/Off and Volume Up.
Remote control can be done by sending signals through either infrared light (like a TV remote), visible light, radio waves, wires, fiber optics, or by soundwaves. The typical television remote uses infrared and just like visible light and laser signaling it requires a line-of-sight connection.
These light switches communicate with a transmitter via a radio signal. The transmitter is typically a small remote powered with batteries. ... The advantage of relying on radio frequency to remotely operate a light switch is that your remote should work within a 150-feet radius
