The highlight of what the company’s demonstrating with Sprint is that it’s commercial hardware, downsized through cycles of development into something that can go on a real-world cell tower, Nokia says.
5G will take massive MIMO even further, using much higher frequencies such as 28GHz. There’s a lot of spectrum up in those bands to deliver even more capacity, but only in relatively small areas, said John Saw, Sprint’s chief technology officer. At that point, the 2.5GHz network will offer better coverage and will probably serve as an anchor for the 5G network, he said.
