​With 5G, carriers hope  to deliver data to smartphone users at speeds 10 times as fast as on  today’s 4G networks, and with only 1 millisecond of delay.

Both Verizon and AT&T say their 2017 fixed wireless networks will rely on millimeter waves, which are arguably the hottest new 5G technology. Millimeter waves are officially defined as waves transmitted at frequencies between 30 and 300 gigahertz, and they are between 1 and 10 millimeters in length.
