Machine-to-machine communications at millimeter wave frequencies

In this paper, for the first time, machine-to-machine (M2M) communications with optical millimeter wave technology is proposed for healthcare application. Optical Carrier Suppression (OCS) method is proposed with dual electrode-Mach Zehnder modulator (DE-MZM), where carrier suppression of > 25 dB was achieved. A 40 GHz carrier was successfully generated in electro optical method with the ability, not limited to, transmitting up to 1.486 Gbps. For a wireless transmission of 5 m distance, the bit error rate (BER) of 10

exhibits minor penalty compared to a back-to-back system.
