There is little doubt that 5G -- the next-generation wireless standard that promises hyperfast speeds with almost no latency -- is the key game-changing technology for 2019. But just how many 5G-compatible devices will we see in the new year, and how disruptive will it really be? 

While most companies will hold back their phone announcements for the Mobile World Congress show in Barcelona in late February, expect to see Chinese handset makers like Huawei use the Vegas spotlight to make a splash. Meanwhile, chipmakers like Qualcomm, Nvidia and Intel will likely tout their 5G bona fides, while carriers like Verizon and AT&T will talk up 5G plans at keynotes and panel discussions throughout the week.
