Maximum transmittable data rates for Millimeter-wave fixed wireless links

Abstract

Smartphones, video streaming and social networks lead to an increase of the transmitted data rates in the telecommunications networks by about 40% per year. To keep pace with the increasing data rates, new ideas for spectrum efficient data transport with low energy consumption are required. Electromagnetic waves in the Millimeter-region of the spectrum are very promising for this purpose since they offer large unregulated bandwidths. However, weather conditions like rain or fog can drastically decrease the transmittable data rates at these wavelengths. Here we will show that fixed wireless links with a distance of 1 km and maximum data rates of around 1 Tbps are possible with just one source. This opens the way to solve the so-called last mile problem.
