One of our links, using NV2 and 5.xGHz is experiencing regular latency spikes. It’s a long haul, 17mi., signal at -59, connect rates settle in at 243Mbps/270Mbps on between two RB433AH’s with R52Hn feeding PacWireless 32db DB dishes . Latency is all over the map, and I’ve tried it on frequencies I’m pretty darn sure there isn’t any interference on, and I can’t get it to settle down. Tcp throughput is around 90Mbps, with short spikes down. Anyone else seeing this?
Is your cell radius set right? if it’s ptp you can probably set your tdma period size to 1ms
but i suspect it’s just a reflection of the fact NV2 is so new and isn’t stable. i have 7 ptp links and when i switched them from nv2 to nstreme the latency became more jittery relative to nstreme so i figured i’d just switch back and wait for improvements.
Hi Colbert, it’s probably not NV2, as I have other links on different hardware that are pretty good in the jitter area…although I have an RB600 that is rebooting every several hours now on 5.0rc1..but others in the mix are not, so go figure (and it won’t produce a supout on crash, either). I’m going to set up our back up bh that parallels this one with the jitter on dual polarity, 5.0rc1, n, and see if I can get a better result on different hardware between the two locations. Maybe it’s a bad R52Hn or something, even though the hardware is brand spanking new on both sides.
Time to post up shots of your config so we can see what you have.
Verify your POE ratings on the RB600 reboot issue.
