AT&T, Verizon Wireless, and other carriers will start to launch 5G networks next year. But what exactly is 5G? Here's what we know so far.

5G Will Enable Mobile AR/VR

So…what about phones? The biggest change 5G may bring is in virtual and augmented reality.

Sprint recently demonstrated streaming wireless VR at the Copa America soccer tournament. The small cell aspects of 5G may also help with in-building coverage, as 5G encourages every home router to become a cell site.
