Abstract :
Experimental results obtained on two line-of-sight links at 36 GHz and 55 GHz operating on a 4 km path across central London are summarised. Measurements confirm the predicted low-frequency enhancement of the spectral density of the log amplitude scintillations in the region of the 60 GHz oxygen absorption peak and the results indicate that large horizontal-scale sizes have a strong influence on the amplitude scintillations. Results on long-term attenuation variations due to the oxygen absorption peak, attenuation due to rainfall and long-term statistics are also presented.
