Millimetre-wave communication systems have a very high potential to become mobile technology of choice for future 4G and 5G network architectures, which has led to many researchers carrying out studies regarding the effects of the atmosphere on radio propagation. There is growing interest in the use of millimetre-wave spectrum as a potential candidate for the provision of high capacity, short range, and backhaul solutions within future 5G ultra-dense network infrastructures. However, these frequencies are highly susceptible to atmospheric conditions and therefore a more detailed understanding of such behaviour is required. This research presents results from a one-year trial of a 60GHz short-range point-to-point link test between two building rooftops at the University of Salford, UK. In this research, a short-range 60GHz radio link measures power attenuations in millimetre-wave ranges with simultaneous measurement of weather parameters. The results obtained confirm a strong correlation between path-loss and the impact of rain and atmospheric gases as predicted by the ITU path-loss model but also highlight a discrepancy. Further analysis revealed that rain duration appears to be having a detrimental effect on link performance. The experimental data from this trial is presented as evidence of the potential impact of rain at 60GHz. The results also confirm the attenuation due to atmospheric gases (Oxygen absorption and water vapour) agree with the attenuation calculations from ITU recommendation for atmospheric gases. The results having considered impacts due to atmospheric gases and rain as per the ITU recommendations, there is a general residue of between 1dB and 2dB path loss throughout the month, interspersed by definite larger peaks ranging from 3dB to 9dB. The extra 3dB to 9dB of residual path loss, is unaccounted for by the ITU path-loss model. The analysis and discussion of measurement results are presented. The results also confirm that the link throughput can be maintained except in the most extreme weather conditions.
