The first company to bring 4G LTE to the United States - Verizon - is now testing 5G. This is a name for a faster sort of mobile internet. That's wireless internet that brings data to your smartphone. What's the difference between 4G and 5G? Speed, mostly. Verizon suggests that though "by nearly all accounts, 5G technology should be introduced in the U.S. sometime after 2020," they'll be starting field technology trials next year. The mobile internet will get faster, and this new wave of faster internet will be brought to market faster than expected thanks to Verizon.
