UHF propagation in mountainous terrain

Digital Mobile Spectrum Limited (DMSL) and the four UK MNOs are required to propose a propagation model to Ofcom with which to assess the geographical coverage of the Shared Rural Network. Standard propagation models are unlikely to give reliable predictions in the mountainous terrain where the SFN is to be deployed. Plum were contracted to[…]

Measurement of vegetation loss at 3.6 GHz

On behalf of a UK telecommunications operator, we made measurements of the attenuation due to the woodland surrounding a satellite Earth station. The measurements, at 3.6 GHz, made use of a specially-developed channel sounder. Measurements were made in both summer and winter, and the results have been incorporated in ITU-R Recommendation P.833.
