Re: [AFMUG] UBNT 900 channels

2016-06-13 Thread George Skorup

Yep, I know. Could be anything. This signal is very hot though. We've
seen baby monitors and cordless phones go bad and start spewing all
kinds of crap over the years.

And remember, Canopy 900 FSK is listening on an 8MHz wide channel.
That's why it looks so bad. And like I said, it's obviously overload the
receiver. Whatever it is, it's more than 36dBm EIRP. And there *are*
licensed users in the 902-928 band, besides even amateurs.

There's public water meters in town, but it's not usually very chatty.
They're still on the sleepy meters where they drive around and wake them
up to read them. And that's on a fixed channel at 915.5.

There's also Commonwealth Edison rolling out smart meters. They're
installing them now. All FHSS. No repeaters up yet. Mesh is not
activated yet. Next year they say.

Did I mention that I hate 900? Only gonna get worse.

Yeah, sure, if your design goal is to make your L3 backbone harder to
troubleshoot and more failure prone in chains of non-redundant devices. I
suppose I could put a 48 port 1000BaseT switch in front of each router and
put the microwave PTP linked OSPF /30 BB interfaces each on their own vlan,
with one 10GbE from router to switch, but I'd be silly to do so.

A thing that is barely more capable than a Cisco 3750G (which can do static L3 routes or iBGP) is NOT a real router. It's a switch.

Other notes: it appears they’re keying it up.. so you get to pay extra to unlock capacity to 1100Mbps and again to unlock max capacity to 2200Mbps.
Oh and if you want AES-256, you get to pay again. The 1MB packet buffer.. seems low.

Anybody else have any thoughts? Anybody got one yet?

The NetVana 1544 is also a L3 Switch and does OSPF/BGP too! Heh.

There -could- be a router doing L3 behind the switch.  It's not that
uncommon, right?
