We've got a 700' drilling ship moored about a mile off our coast for a
few days for repairs.

Since it came in, 900mhz within a couple miles of it has stopped
working. We went out with the spectrum analyser after the Alvarion
Thanks. Just a few more questions please.
1. If you use self-configuring gear doesn't that mean at least as far as the
backhaul it's all on the same frequency? Wouldn't a system where you manually
configure the backhaul legs to use separate frequencies reduce
self-interference and allow

I know what my position is, and it should be clear to most of you.
However, the FCC needs to hear from the smaller operators, and from small
business saying Hands off! We can't afford your wishes. And
Plug the damn hole! - lol! Sorry, I couldnt help it :)
Since it's a UK ship, I wonder if this has anything to do with it?

Possible but don't quit believe so since 900MHz GSM uses 890-914Mhz for
uplink (cell to base station), and 921-960Mhz for download (basestation to
cell). That strong signal wouldn't come from cells and the basestation would
just ruin the top part of the frequency. Maritime cell systems I seen

That's funny. That article claims that Below 900 MHz the target radar cross
section increases exponentially, however the increased radar cross section
means that there is much more radar return from undesirable sources, such as
cloud cover and rain (cf. weather radar). but when I worked on
yes Greg, we used to think a Smart Bridge was the Cat's Meow then the CB3
came out! :-)
Since that's an exploration drilling ship, I'll bet it's some sort of sub
surface positioning radar/ sonar/ or some such, linked to the thrusters and
gps to keep it on position. I wonder if it could be worse
Another option is they're running something that's not street legal (something
you couldn't get away with running ashore but out at sea you don't have to
worry a about an FCC van bristling with antennas direction finding it's way to
your location) that normally they just run at sea and someone

You know your stuff in-side out, hands down there is no argument about
that :)
Getting back to your original quest... You are going to find the following:-
The non-licensed wireless world is not as mature as the wire line
world... think of today's wire less world being what the wire line world
