Product List
The transmitter’s role in wireless communications is to feed a signal to an antenna for transmission. A radio transmitter encodes data into RF waves with a certain signal strength (power output) to project the signal to a receiver. The receiver receives and decodes data that comes through the receiving antenna. The receiver performs the task of accepting and decoding designated RF signals while rejecting unwanted ones. RF communication can be compared to simple audio communication; the vocal cords transmit sound waves that may be received by the eardrum. Megaphones can focus and direct the sounds waves to make communication more efficient.
