By 2020, Ericcson says that North American smartphone users will chew through 14 GB of data per month, up from just 2.4 GB right now.

One option is to use unlicensed airwaves to send LTE signals. This would use airwaves typically reserved for garage door opener signals, baby monitors, and (most important) Wi-Fi signals. The technology is called LTE Unlicensed, or LTE-U, and it's causing a stir among some tech companies.
