The influence of hydrometeors on a MMIC-based wireless data transmission at 240GHz carrier frequency was experimentally evaluated in a climatic wind tunnel over a distance of 90 m. Successful transmissions of up to 24 Gbit/s QPSK modulated signals through heavy rain at 43 mm/h and dense fog at 3 g/m(3) is achieved. The climatic impact is evaluated in terms of EVM. Reducing the bandwidth makes a transmission still possible with a BER < 1 x 10(-3) under conditions, where a free space optical link would fail.
