The limited availability of spectrum in sub 6 GHz bands has created substantial interest in bands above 20 GHz for 5G deployments. Likewise, although high reliability is more easily achieved in lower bands, it is highly likely that mmWave bands will also be considered for low latency, high reliability aplications. In addition to challenging propagation conditions making high reliability difficult to achieve, the use of narrow beams with analog beam forming increases the latency for bursty uplink packet transmissions. We begin with a discussion of emerging applications that require high data rates with ultra-reliability at very low latencies for which mmWave is a natural choice. We then highlight some of the key challenges and describe factory floor channel measurements that show reasonable propagation conditions suggesting viability of mmWave solutions. Finally, we will discuss some novel solutions to achieve high reliability and low latency in these bands.
