Out of these 60+ clients some 40 are allowed to use up to 30Mbps download, some 16 upto 12mbps and 6 of these (for test purpose) upto 50Mbps.
These are all Mikrotik SXT's, a mixture of 'ac' and 'n' units and we have 2 C5's. So all in interop mode and all in < 450meters distance.
I am myself (my house) connected via a C5 and behind it a G2 (that is outperforming any other make wifi I have used in the last years....!) and I can on my mobile very consisten get www.speedtests of 30+Mbps, often 40+ and not rarely just get the full 50+ assigned (queues in main gateway) Mbps.
I am very happy with the A5 althoug we do have an occasional (once to twice a day, sometimes one or two days without) 'network storm' that kicks some units off the AP and most clients become unusable. We are working together with Mimosa to get this one nailed. If we do this is by far the best performing AP there is on the market I believe!
