Clutter loss measurements and simulations at 26 GHz and 40 GHz

摘要

The World Radiocommunication Conference 2015, WRC-15, identified candidate frequency bands between 24.25 GHz and 86 GHz for future 5G systems. The Radio Spectrum Policy Group of the European Commission selected the 26 GHz band as pioneer for introducing next-generation 5G terrestrial wireless systems in the Union, and the 32 GHz and 40 GHz bands as promising and viable options in the longer term for 5G use. Sharing and compatibility studies for assuring the protection of services to which these bands are allocated on a primary basis are required before the WRC-19 allocates these frequencies to 5G services. These studies need propagation models to calculate interference levels at receivers. New propagation models are needed for the new frequencies and scenarios identified for 5G.New propagation models are developed through simulations or experimental measurement campaigns, each method having its pros and cons. The Joint Research Centre has started an activity working on both. This paper presents preliminary findings on use of a ray-tracing tool to produce clutter loss data and first comparisons with real experimental data, with the aim of validating the ray-tracing tool for the generation of new clutter loss data.
