IR-UWB approach for high bit rate transmission in the E band

Abstract

The recently allocated 71–76 GHz and 81–86 GHz bands provide an opportunity for realising Line Of Sight (LOS) links for directional point-to-point “last mile” applications. An efficient use of this spectrum may allow wireless to finally “catch up” with wires, leading to systems such as “multi-Gigabit wireless Ethernet,” and “wireless fiber.” However, the transmission at such a frequency range shows some additional challenges compared to lower frequency bands, from both technological and propagation point of view, which makes difficult to use them efficiently. In this scenario, IR (Impulse Radio) UWB (Ultra Wide Band) technology might offer some more degrees of freedom for the design of a highly integrated and low cost transceiver. This work has at its core the comparison of two main IR-UWB architecture transceivers operating in E band, focusing their performance.
