Re: [WISPA] 5.8GHz Backhaul Radio Recommendations

David, Just for info here but it's possible that your signals were so loud that the receivers were being overloaded. That drives them bananas... jack David E.

I also believe it does MPPP as well, and larger frame sizes as well to get higher speeds. Hence, processor usage is key. When I was testing this - pretty informally, two radios set on the floor of the office about a hundred feet apart - the speeds weren't that much higher, and the latency was all weird. The RF link was pretty good (I think there was 40-some-odd points of SNR), and when I used them in regular AP/bridge mode, or basic WDS, I actually got better performance than when I enabled polling and Nstreme and all the other Mikrotik proprietary magic checkboxes. The throughput was pretty comparable, but when the link was even lightly loaded, pings went bananas. Instead of being consistent, some would be 3ms, some would be 100ms. I figured that was because my little ping packets were being bundled up with other packets, then transmitted when it was most efficient for the radio, as opposed to being sent on-demand. First, is that pretty close to accurate? Second, in the real world, when you're trying to do something like VOIP or gaming that's sensitive to latency, how noticeable is it?
