Hughesnet had a filing suggesting either no latency benchmark, or 750 ms.

Well if there is a mention of latency (and whether there is or isn't) will
speak volumes about the influence (or lack thereof) of the satellite broadband
industry. And if there is a specification for latency (and I've never
understood why there isn't), then it should surely be < 500 ms, and more
reasonably < 100 ms, or possibly < 200 ms. I think the tolerance breakpoint
for any VoIP-type service is in the area of 200-250 ms.
Exede claims to support some type of VoIP service these days. Has anyone had
the opportunity to see how this actually works (or doesn't)?

100 ms end to end. That user device to the far server. If you're like Josh in
Alaska, there's 30 - 40 ms before you even get anywhere in the cables down to
Seattle. The Internet seems to work okay for him.

I think Kurt’s point, which I agree with, is this is a PTP product, and
backhaul latencies get multiplied by the number of hops, while you only have
one “last mile”.
You can perhaps use licensed or other FDD radios for the first few hops and
go cheap with the last few hops at the farthest reaches of your network,
especially if there is a plan to upgrade these in the future. That doesn’t
work so good though if you have a backhaul ring.
I agree with Rory that 10 ms isn’t a bid deal. I don’t agree with Mike that
100 ms doesn’t really matter. The problem is that a whole bunch of 10 ms links
adds up to 100 ms.
Also I worry that some CDN’s use fancy new TCP stacks that back off based on
latency rather than packet loss as an indicator of congestion. I think they
are wrong to assume that everyone uses infinite buffers for queuing rather than
packet drop, but they don’t ask my opinion.

Not to mention the UBNT gear under load has at least that much latency...

ADSL latencies used to be over 40ms or more. Cable latencies are about 10ms
from my router to the first hop so 10ms isn’t that big a deal. I agree with
you Mike.

A lot of WISPs get hardons over low latencies, but as long as end-to-end is
under 100 ms or so, it doesn't really matter.

I wonder if WISPs are going to be part of a trend toward higher latencies.
It used to be customers mainly did web browsing and really noticed whether
the websites snapped up immediately or lagged. Now everyone is streaming,
streaming, streaming. And websites are more worried about tracking cookies and
on-the-fly ad auctions for your eyeballs than responsiveness. Plus people use
mobile devices and are accustomed to the higher last mile latency of 3G and LTE.
Still it’s a little disappointing to backslide on latency because customers
don’t value quick response like they used to. They just want mass quantities
of data to watch video, as cheap as possible.
I guess gamers still care about ping times.

Jeremy,
Yes I had issues but I didn't call support. It took me almost 2 hours to
get the two radios to see each other but I finally got them too. I wasn't
following the PTP quick start guide like I was told to. When I initially
configured the radios I disabled the 2nd port (called WAN) in the manual. For
some reason they would not link until I turned it back on. Even though I wasn't
using the WAN port.

Just got done testing a Trango Altum AC PTP link on the bench. Units
are 25db integrated panels. Did a 40mhz channel test and 80mhz via UDP. I tried
a TCP test between two RB2011's and best I seen was 175-180'ish and that was
with both 40 and 80mhz channels. CPU seemed to be maxing out on the 2011's.
Has UNI-1 bands and ISM bands. I was hoping it had the middle DFS bands
but it doesn't :(
