Experimental Study of MIMO-OFDM Transmissions at 94 GHz in Indoor Environments

Millimeter wave (mm-wave) frequencies have been proposed to achieve high capacity in 5G communications. Although meaningful research on the channel characteristics has been performed in the 28-, 38-, and 60-GHz bands in both indoor and short-range scenarios, only a small number of trials (experiments) have been carried out in other mm-wave bands. The objective of this paper is to study the viability and evaluate the performance of the 94-GHz frequency band for MIMO-OFDM transmission in an indoor environment. Starting from a measurement campaign, the performance of MIMO algorithms is studied in terms of throughput for four different antenna configurations. Ingeniería, Industria y Construcción
