Our experience with Cambium EPMP 3000 series (802.11AC standard) was that it had substantially higher latency and jitter than Airmax AC. Perhaps this is because fq_codel is baked into Airmax but not EPMP? Would be interesting to see if this has changed with EPMP 4000 series, which uses the 802.11AX standard. Our PtP Cambium EPMP 425s all work great with regard to latency in comparison to anything else out there, but we won’t know about the PtMP performance until EPMP 4000 APs are out to market. Perhaps Cambium can put Dave in touch with the Beta testers of the EPMP 4000 APs to see if there’s opportunity to fix queuing before 4K hits the market? Getting EPMP latency and bloat reduced would make it very competitive. Latency was our main concern that held us back from deploying EPMP. Having better queuing in EPMP 4K would be really great.
