Patent ID: 8565325

Claim:
A method for transmitting and receiving 60 GHz band signals in a first wireless device, the method comprising: communicating with a second wireless device and a third wireless device using two communication modes, a first of the communication modes enabling communication with the second wireless device using single-carrier demodulation, a second of the communication modes enabling communication with the third wireless device using orthogonal frequency division multiplexing (OFDM) demodulation, neither of the communication modes using OFDM modulation, the communicating including: receiving, from the second wireless device and in the first communication mode, a 60 GHz band signal having been modulated in accordance with a single-carrier modulation scheme; receiving, from the third wireless device and in the second communication mode, a 60 GHz band signal having been modulated in accordance with an OFDM modulation scheme; in response to receiving the 60 GHz band signal having been modulated in accordance with the single-carrier modulation scheme, demodulating the 60 GHz band signal through a single-carrier demodulator of the first wireless device; in response to receiving the 60 GHz band signal having been modulated in accordance with the OFDM modulation scheme, demodulating the 60 GHz band signal through an OFDM demodulator of the first wireless device; and transmitting, from the first wireless device and in the second communication mode, a 60 GHz band signal to the third wireless device from which the 60 GHz band signal having been modulated in accordance with the OFDM modulation scheme is received, the 60 GHz band signal transmitted by the first wireless device modulated using a single-carrier modulator of the first wireless device and not an OFDM modulator, the first wireless device not including the OFDM modulator and not capable of modulating signals using the OFDM modulation scheme.
