I would not mind at all if the ietf had a wg with the ieee and the wifi alliance and whoever else might care, to make wifi better in a huge variety of ways. I remain perpetually astonished that a technology beloved by and used by billions (with billions to come) has so few advocates, so few working on actual interoperability, so many bad implementations, and so little research funding. the general public has their priorities straight: https://www.google.se/search?q=image+hierarchy+of+needs+wifi&source=lnms&tbm=isch&sa=X&ved=0ahUKEwi32M36qbjJAhWEqnIKHSseCiMQ_AUIBygB&biw=1135&bih=1072 For those that haven't seen it: https://www.youtube.com/watch?v=Rb-UnHDw02o I am happy that a little bit of funding towards merely getting per station queuing working looks to arrive next year. Tackling handoff in any sane way with the current mess, looks harder. _______________________________________________ homenet mailing list [email protected] https://www.ietf.org/mailman/listinfo/homenet
