Am using UNIFI AP, and Unifi AP-LR series.
Nice thin client AP with controller, best of all license if free for controller software.
Overall, controller features aren't impressive but suitable for average SME business and cafe environment usage.
One thing cool compare to average home AP like TPlink, I have been switching on the unit for months, still running stable.

dun think so, Time OLT and CPE OLT is tied by proprietary protocol.
However, you can always ask Time about it, their technician seem better than TM.
