The company did say the deployment will include the use of very high millimeter wave wireless spectrum, which is key to reaping all the promised benefits of 5G.

5G is the next-generation of cellular technology, which promises download speeds that are 10 to 100 times faster than today's 4G LTE networks. But the real game-changer with 5G is the reduction in network latency, which will make the network respond almost instantaneously. This will enable mobile devices to do things never before imagined, and usher in a new wave of apps that will leverage newer technologies like augmented and virtual reality. It'll also allow for things like communication between autonomous cars.
