5G is expected to support around 29 billion devices connected to IoT by 2022 [164, 165]. eMBB delivers high data rates across 5G coverage area, where downlink data rates of at least 100 Mbps per device is supported over a typical dense urban environment. With the increased bandwidth, the high-performance connectivity is also sustained for indoor spaces such as industrial campuses [166]. Therefore, bandwidth hungry applications such as virtual reality for remote maintenance worker assistance and production line imaging for quality inspection significantly benefit from the higher bandwidth available through 5G eMBB. In addition to fast data rate, 5G eMBB provides low latency of 4 ms over the air, enabling real-time data transmission, processing, and decision-making for autonomous warehousing robots and industrial machine control [167]. One approach for providing eMBB is to implement millimeter wave (mm-wave) technology and install high-frequency mm-wave antennas [168].
