Abstract :
We demonstrate the first millimeter-wave Gb/s transmission of broadband wireless signals using uncooled directly modulated lasers to give a low-cost solution. Data signals to and from the base station are distributed at intermediate frequencies for reduced chromatic dispersion together with a remote 40-GHz local oscillator signal for frequency upconversion/downconversion. Coarse-wavelength-division-multiplexing components are employed throughout the network allowing uncooled lasers and low cost filters to be used. Error-free transmission (BER < 10-9) has been achieved for the downlink and the uplink. The paper also provides detailed system link analysis together with simulation results.
