Massive multiple-input multiple-output (MIMO) systems are cellular networks where the base stations (BSs) are equipped with unconventionally many antennas.
The use of large-scale antenna arrays can bring substantial improvements in energy and/or spectral efficiency to wireless systems due to the greatly improved spatial resolution and array gain.
We propose massive MIMO unlicensed (mMIMO-U) as a high-capacity solution for future indoor wireless networks operating in the unlicensed spectrum.

In this paper, we investigate the feasibility of using Massive MIMO to provide connectivity to Industrial Internet of Things (IIoT) wirelessly.
A key component for the success of Massive MIMO is the asymptotic orthogonality of channel vectors.
Demand for wireless throughput, both mobile and fixed, will always increase.
We consider a multicell MIMO uplink channel where each base station (BS) is equipped with a large number of antennas N.
