Carriers around the world have launched their 5G networks. Nationwide coverage is available in the US from the big three providers. Compatible smartphones are getting cheaper. The next-generation wireless technology is rapidly maturing.

Still, it's worth considering the technology that will be around the next corner and looking at what wireless researchers are thinking about in terms of its potential.
