Abstract
This work presents directional radio channel measurements in the W-band using a commercial versatile channel sounder based on a vector network analyzer (VNA), capable of measuring scattering parameters from 75 to 500 GHz with frequency converters. The commercial setup has been modified by increasing the distance for one of the converters using precision coaxial cables and avoiding the use of amplifiers. Firstly, initial distance-dependent single-input single-output (SISO) measurements of indoor radio channels are presented to assess the validity of the setup in the 75–110 GHz frequency band with highly directive horn antennas. Then, single-input multiple-output (SIMO) radio channels were measured at 94 GHz using one directional and one omnidirectional antenna mounted on two positioners. Initial channel characterization is presented comprising root mean square (rms) delay spread, rms angular spread, K-factor, and path loss in an indoor environment at 94 GHz.
Highlights
The UE Horizon 2020 considers the extension of wireless communication systems to frequencies above 60 GHz as one of its priorities; it aims to fill the gap between the millimeter and the terahertz spectrum
This paper is organized as follows: Section II focuses on the description of the channel sounder based on a commercial vector network analyzer (VNA), Section III presents wideband measurements in the W-band using horn antennas to assess the validity of the setup, Section IV focuses on the channel characteristics at the 94 GHz frequency for an indoor environment, and Section V concludes the work
For comparison purposes, the horn antenna coordinate system was aligned such that the maximum received gain could be obtained for 55° angles between the UCA and URA, i.e., the mean angle is always facing the Rx, and it will be plotted in such a way for all results
Summary
The UE Horizon 2020 considers the extension of wireless communication systems to frequencies above 60 GHz as one of its priorities (http://ec.europa.eu/programmes/horizon2020/); it aims to fill the gap between the millimeter and the terahertz spectrum. The required dynamic range is higher than at lower bands, i.e., a path loss of 72.4 dB is theoretically obtained at 1 m for 100 GHz. To alleviate this issue, one omnidirectional
