There's some debate about whether OAM demonstrations are just MIMO, and some suggestions that the eigenmodes are equivalent. Either way, there will be regulatory hurdles to more efficiently using the spectrum. I like the perspective put forward in this post: http://www.reed.com/blog-dpr/?page_id=117 http://www.reed.com/blog-dpr/?page_id=117
