== Carrierless modulation systems == {{unreferenced-section|date=November 2020}} The information in a modulated radio signal is contained in the [[sideband]]s while the power in the carrier frequency component does not transmit information itself, so newer forms of radio communication (such as [[spread spectrum]] and [[ultra-wideband]]), and [[Orthogonal frequency-division multiplexing|OFDM]] which is widely used in [[Wi-Fi]] networks, [[digital television]], and [[digital audio broadcasting]] (DAB) do not use a conventional sinusoidal carrier wave.
