60 GHz millimeter-wave broadband wireless access demonstrator for the next-generation mobile internet

A novel demonstrator of broadband wireless access for future mobile internet was investigated using steered antennas and optical 60 GHz millimeter-wave sources without rf-electronics in the control station. Key device was a self-pulsating laser designed for 60 GHz operation and a remote stabilization by a sub-harmonic pulse source in a central master control station. Error free operation of HFR system at 155 Mb/s (BER less than 10^-10) was demonstrated, without penalty neither for fiber distribution of the optical microwave signal nor for the remote stabilization of the SPL via fiber. Future broadband wireless connections can be done in a cost effective way by the proposed system based on the SPL as optical millimeter-wave source applying optical beam forming.
