Cellular telephones use radio waves to transmit and receive signals. These radio waves are a type of electromagnetic wave that allows for wireless communication between devices.
Electromagnetic waves, such as radio waves, transmit information from one antenna to another. These waves carry the signal that contains the information being transmitted, like radio broadcasts, Wi-Fi signals, or cellular communication.
In the cellular phone system,cellular phones transmit and receive radio waves that travel to the nearest tower.Cellular phone transmit and receive high signals using high frequency microwaves.Hope this answers your question (: -anonymous xx
each channel can only transmit signals in one direction signals are transmitted as rf waves can be used to transmit multiple signals at once

Alexander Graham Bell's telephone worked by converting sound waves into electrical signals, which were then sent through wires to a receiver that converted them back into sound. The telephone relied on the principles of electromagnetism to transmit and receive these electrical signals, specifically by using a metal diaphragm and an electromagnet to convert sound waves into electrical signals and vice versa.
The analog method of signal transmission uses radio waves to carry signals. Digital transmission involves the use of satellites to transmit signals.
how is data retrieved from the telephone? the transmitter converts the sound waves to electrical signals which are sent through the telephone network to the receiving phone. the receiving telephone converts the signals into audible sound in the receiver.
Radio waves are used in cell phones to transmit and receive signals by converting sound and data into electromagnetic waves that travel through the air to nearby cell towers. These towers then relay the signals to other cell phones or the internet, allowing for communication between devices.
Analog sound waves are converted into electromagnetic waves (radio waves) for transmission over telephone networks. These radio waves carry the audio signals between the caller and receiver.
Electromagnetic waves, such as radio waves, microwaves, and light waves, are commonly used to send signals for communication purposes. These waves can carry information through the air or other mediums to transmit data over short or long distances.
