[ANSS-netops] ubiquiti nanobridge

[Croker, David]

Hey Mitch,

We have two sets of Ubiquity Bullet Titanium radios in service in the
NCSN.  One set is a link of 2 pairs of 5.8GHz radios running at 10MHz Bw in
the Parkfield area.  They've been there now for at least a year and have
worked pretty reliably.  The other pair with the same specs is on a link
from Menlo Park across the Bay to Newark, and it's been on for over a
year.  Haven't used the Nano's at all.

For the price, you can't beat them.  I'm still not sold on the product
though, and it's hard to describe why.  We've never had a very warm fuzzy
feeling about them for some reason.  We did have 2 of the first 8 we
purchased need to be factory reset several times to get them working which
doesn't help.  We've also learned that when one hiccups, its mate loses
sync and both have to be reset to make the link come back alive.  That also
happened to us in the first 2 months of deployment which didn't help, but
it hasn't happened since.  We've since learned that--supposedly--if both
radios have access to an NTP server, they may not both have to be  power
cycled.  The software is decent, which actually isn't bad also considering
the price.

The jury is still out for us.  They are certainly a cheap solution, but so
far we don't have plans to install anymore of them unless we absolutely
cannot afford any of the much nicer ISM-band radios for data collection.

Dave
