What do you think of LTE-LAA? I do think very strongly that actual usage of 802.11 can be made vastly more efficient, that we can use up a great deal of the mac currently being left unused, and schedule txops way more efficiently - and that I'd love to test with michal's patch set against the LTE-U tests cablelabs, etc which did 100 stations before (stock): http://blog.cerowrt.org/flent/drr/10tothe5.svg after http://blog.cerowrt.org/flent/drr/newcode.svg I became mortally opposed to LTE-U (lacking exponential backoff and ignoring sparse station behavior, as well as today's crappy wifi drivers - along with some very dubious benchmarks), but have not poked much into LTE-LAA. I freely admit to loathing the 802.11 mac, and IF LTE-LAA could be as open, accessible and usable to ordinary users as wifi was, would be more embracing of it. > > > On Wednesday, 11 May 2016, David Lang wrote: >> >> On Wed, 11 May 2016, Luca Muscariello wrote: >> >>> It's surprising that 802.11 standard never considered time fairness in >>> the >>> EDCF.
