This is certainly radio interaction concerning a spacecraft and an Earth-based mostly ground station, or One more spacecraft. Conversation with spacecraft consists of the longest transmission distances of any radio one-way links, up to billions of kilometers for interplanetary spacecraft. To be able to get the weak indicators from distant spacecraft, satellite floor stations use substantial parabolic "dish" antennas as many as twenty five metres (82 ft) in diameter and very delicate receivers. Large frequencies during the microwave band are applied, since microwaves pass through the ionosphere without the need of refraction, and at microwave frequencies the higher-gain antennas needed to concentration the radio Vitality right into a slender beam pointed with the receiver are small and choose up no less than House inside of a satellite.

If the doorbell is pressed it sends a sign to your receiver inside the home with a speaker that sounds chimes to point a person is on the door. They typically utilize the two.four GHz ISM band. The frequency channel used can usually be transformed from the owner in case A different close by doorbell is utilizing the same channel.[149][150]
Unmanned aerial automobile (UAV, drone) – A drone is undoubtedly an plane devoid of an onboard pilot, flown by remote control by a pilot in A different place, commonly in a piloting station on the bottom. These are utilized by the army for reconnaissance and ground assault, and more not too long ago through the civilian entire world for news reporting and aerial photography. The pilot takes advantage of aircraft controls just like a joystick or steering wheel, which produce control signals which are transmitted towards the drone by radio to control the flight surfaces and engine.

Interaction satellite – an artificial satellite applied as being a telecommunications relay to transmit info involving greatly separated factors on the planet. These are utilised as the microwaves useful for telecommunications travel by line of sight and so cannot propagate throughout the curve on the Earth. As of 1 January 2021[update], there were two,224 communications satellites in Earth orbit.[112] Most are in geostationary orbit 22,200 miles (35,seven hundred km) earlier mentioned the equator, so that the satellite seems stationary at the identical place during the sky, so the satellite dish antennas of floor stations might be aimed forever at that place and would not have to maneuver to track it. Inside a satellite ground station a microwave transmitter and large satellite dish antenna transmit a microwave uplink beam to your satellite.
