Abstract
A gateway includes a modulation scheme conversion device, which includes a backscattering tag and a tag signal generation unit configured to provide a tag signal to the backscattering tag. The modulation scheme conversion device multiplies a radio signal, which has been modulated with a first modulation scheme, and the tag signal to produce a multiplied signal and to reshape the multiplied signal using a second modulation scheme to produce a reshaped signal and backscatters the reshaped signal. The signal, which is reshaped with the second modulation scheme and backscattered, is provided to a receiver of second modulation scheme signals and then provided to the Internet.
