Microwave and satellite systems can be used to transmit audio, video, and other forms of data
Satellites receive signals from Earth using antennas that are pointed towards the ground. The signals are sent from ground stations and relayed to the satellite. The satellite then processes the signal and can transmit it back to Earth or to another satellite.
Polling in satellite networks is electronic signally between satellites to see which one is going to send data. It also requires a receiver that is polled to see if it is ready to transmit data.
Microwave and satellite systems can be used to transmit audio, video, and other forms of data
Satellite Dish is a dish-shaped type of parabolic antenna designed to receive microwaves from communications satellites, which transmit data transmissions or broadcasts, such as satellite television.
A communications satellite operates as a transceiver (TRANSmitter - reCEIVER). Signals from a base station on Earth are sent to a satellite receiver. The data is either stored for a period of time or sent immediately to a transmitter on the same satellite. The transmitters on satellites are positioned to transmit towards Earth or towards other satellites. A base station on Earth will receive the transmitted signals and pass them to land based equipment. As satellite signals rely on line of sight, they each have a range over which they can send signals. Too far round the Earth and the signal won't make it. That's why they can also transmit to other satellites before the signal is finally returned to Earth, far round the globe. The data carried by communication satellites is used for a wide variety of applications. Television, telephones, computer networks and far more are regularly sent to and from satellites.
A satellite communication simply bounces a radio or data wave to another satellite or a receiver on earth. Satellites all act as giant relays for data transmissions.
Microwaves are typically used to communicate with satellites in space due to their ability to penetrate Earth's atmosphere and transmit data over long distances reliably.
