Radio Signal Modulation

Radio signal modulation is the process of sculpting and molding a radio wave to carry and transmit information.

Radio-signal modulation is the process of sculpting a radio wave to carry and transmit information. The modulated radio wave is then transmitted and demodulated at the receiver’s end (i.e., the information is “understood”). With real-time data exchange and transfers, this modulation-transmission-demodulation process is performed repeatedly between the sending and receiving ends, assuming sufficient bandwidth.

Cellular phones, the Web, television and radio broadcasting, satellite communications, and the internet of things, all rely on radio-signal modulation for their existence. Improvements in modulation, coding, compression and the encryption of data allow for increases in data throughput.
