While cellular and WLAN (Wireless Local Area Networks) at low frequencies (1–5 GHz) constantly struggle with the quasi-saturation of spectrum, the EHF band (30–300 GHz) has huge swathes of band available at no cost. The recently allocated 71–76 GHz and 81–86 GHz bands could represent an opportunity to realise Line Of Sight (LOS) links for directional point-to-point ”last mile” ones. This work focuses...
The recently allocated 71-76 GHz and 81-86 GHz bands provide an opportunity for Line Of Sight (LOS) links for directional point-to-point “last mile” links. 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 is characterized by several...

In this work authors investigate the use of IR (Impulse Radio) UWB (Ultra-Wide Band) technique for satellite communications at frequency bands beyond Q/V bands. In particular, the paper shows how an IR UWB communication system is sensitive to typical hardware non-idealities at those frequency bands and compares its performance with the ones of a more classical continuous wave communications system...
