Everyone says they'll be first with 5G

When it comes to the four major carriers, everyone says they are going to be first with 5G. It's always a race to be first with a new generation of technology (and to claim being first, which isn't always the same thing.) The stakes are extra high — both within the U.S. and on the global stage, with China, Korea, Japan and others all looking to be ahead of the game. Expect even more noise (and therefore more confusion) when the cellphone industry's big conference, Mobile World Congress, starts Feb. 26 in Barcelona, Spain.
