Re: [WISPA] Cambium 450, 450m, and epmp in 5.X GHz Comparison

2017-03-22 Thread Nick Bright
I can't comment on PMP450/m because our density doesn't justify the 
cost; but I can say that I've been extremely happy with ePMP.


They did have a firmware problem with 3.2, but it's fixed in 3.3 (at 
least in the RC I tested for them). They've always been very responsive 
to firmware feedback and feature requests.


Performance is great, reliability is great, price is good - reasonable 
for the quality and performance, and I have always been very happy with 
the support level provided by cambium. I've frequently emailed with 
their engineering staff, software developers, and even a few times the 
CEO. They've even helped me resolve a network problem that was clearly 
not related to their products (it seemed like it was at first).


Tier 1 support is tier 1. They're good at asking you to reboot, and 
checking your settings, but if you have a real problem you'll need to 
escalate. The nice thing is, you can. Just ask them.


There are three big points about Cambium that made us choose to switch 
to their platform:


 * Quality hardware at reasonable prices
 * Excellent customer care & support
 * Management software that works

As for real performance numbers: If you have a noise floor in the -95 to 
-98 range, you'll see full throughput (20Mhz channel) of 85Mbps/15Mbps 
on a 75/25 TDD split (yes I know 85/15 isn't 75%/25%, but that's what 
the through puts are) with anything better than about a -72dBm signal.


I've also been using the ePTP mode which isn't TDD (and not synced!). 
Throughput is great for the price, and with a good ~25-30dB SNR you're 
going to see nearly 200Mbps usable aggregate throughput.

Re: [WISPA] Cambium 450, 450m, and epmp in 5.X GHz Comparison

2017-03-21 Thread Mark Radabaugh
We don’t see issues with F/B interference with 450 very often in 5.7 but it’s 
much more significant in 3.65.  Typical issue will be poor SNR for the close-in 
customers even though they have excellent signal.

The sectors hearing each other isn't really an issue with GPS sync since 
they will all TX at the same time.

it's a non issue.

the 450m is designed in every way for high density, high capacity
deployment.

F/B ratio is critical when doing ABAB channel reuse even with sync.  I
imagine the 450m spec sheet states the F/B.
