Patent ID: 8509846

Claim:
A dual radio wireless communication device comprising: a first wireless transceiver conforming to a first communication protocol and a second wireless transceiver conforming to a second communication protocol; wherein the first communication protocol uses a series of frequency channels, one frequency channel at a time, from a set of frequency channels, and the second communication protocol uses a plurality of frequency sub-channels in parallel from a set of frequency sub-channels, and further wherein, the first wireless transceiver is configured to receive a communication message via the one at a time frequency channel, and the second wireless transceiver is configured to transmit a response to the communication message by replicating a power spectrum of the response to the communication message conforming to the first communication protocol on one or more frequency sub-channels, and yet further wherein, the second wireless transceiver comprises: a Gaussian Frequency Shift Key (GFSK) modulation block controlled by the response to the communication message; an inverse Fast Fourier Transform (IFFT) block used to create a carrier frequency spectrum conforming to the first communication protocol; and a mixer for combining outputs of the GFSK modulation block and the IFFT block.
