Changing usage models such as automated vehicles, smart factories, streaming video, and cloud-based applications has placed more emphasis on higher bandwidth and shrinking latency. To meet these evolving needs, 5G promises a 100X speed boost compared to 4G LTE, along with latencies that are an order of magnitude or lower. In addition, 5G specifications call for the new network to connect one million devices per square kilometer, more than 100 times as many as before.
