Just a quick note on the enhanced PTP mode of operation - You will see lower latency in most deployments as compared to the TDD & Flex mode of operation. However, in high interference coupled with long distance environments the flexible mode will do better in terms of tput. At this time, this is per design but we will be addressing and incorporating some of the good stuff from our TDD/Flex mode of operation into the enhanced PTP to bring back the tput in the above conditions. Please note that we are also working on a 2.5ms frame to reduce latency in the PMP mode of operation.

This link isn't actually in use, since it was replaced with a Mimosa link, so it's not really the best test... but it's also far from low noise, since both ends of the link are within a couple of the Mimosa radios, and on the same path.

I had a radio running at 30dbm and it would crap out within 12 hours - ethernet port would quit working. I dropped it to 28dbm and it works fine YMMV. The new PTP master/slave mode was supposed to cut latency - from what I saw it only cut it by about 5ms and the performance cut was dramatic.

I see there's two PTP modes though. One is ePTP Master and Slave. The other is just PTP. Look like the PTP mode requires fixed distance settings at both ends? And ePTP mode does auto-ranging like Canopy BHM/BHSs perhaps? When are we going to get 2.5ms framing to sync with Canopy? I see we can now turn on the aux port PoE output and it'll power another ePMP or Canopy SM. PTP from a customer's barn to their house got easier. But that additional 20ms of latency is not so good, so hopefully PTP mode for a 1000' link works.
