It’s definitely more useful to the licensed LTE guys where noise is controlled, I certainly know that’s the case so far with Kumu.
Possible it could make it to Wi-Fi at some point, but it would probably be 5 years out even after 802.11ax if it’s “standardized” (low cost) versus custom system integrated (expensive). Nobody really has it in silicon process yet, last demo I saw was a giant box the size of the old school hardback dictionary. 256 QAM is hard enough to hit already in the real world, so I do wonder if the tradeoff for full duplex in the same channel could be half the encoder speed. "But these materials are not compatible with silicon chip technology, and ferrite circulators are bulky and expensive” - awesome, but gonna be a while. There’s a few other way more practical and low cost technology changes being worked on that I’m way more excited about for outdoor wireless and Wi-Fi markets in scaling and noise management.
