[sudo-discuss] TV white spaces technology?

Hi, is anyone tracking how are things developing regarding TV white spaces technology [1] in US and EU? Microsoft has been doing some pilots [2] in Africa and Ofcom in UK [3], and there is a interesting study [4]. But I don't see if it is actually possible to buy any 2nd or 3rf gen devices either in US or EU. If anyone has some links please share them. What is the current legal situation, will tv white spaces spectrum be free to use, ie ISM or not? I have seen some discussions at the end od 2015regarding making tv white spaces ISM but nothing since then. I was trying to find some up to date information for EU and tv white space technology, but came short. If anyone is tracking this please share any info you have. Thanks, Valent.
