Re: [WISPA] OSBridge

2008-08-27 Thread Graham McIntire
I have about 60 customers or so using the 5GXIs connected to Mikrotik
APs using 10 MHz channels.  It works out great as long as you don't
have any trees in the way.  I don't have any experience with their APs
or using polling with them however.

A better option may be the Asus Eee PC,
http://eeepc.asus.com/en/701.htm  They're so popular most retailers
are having problems keeping them in stock.  I've been considering
getting one for roof site surveys to replace my existing aging laptop.
 People have reported successfully getting Windows XP installed on it,
although it's by no means fast.

Re: [WISPA] Which UPS to use?

Read close, it only applies to ILECs, CLECs, and CMRS (commercial

not required if you're not a CLEC.

Re: [WISPA] Legal Charges used in Malicious Interference Situations

2007-09-12 Thread Graham McIntire
A neighboring WISP to me ran in to this last year when a new
competitor moved in and placed towers (20' taller than the existing
WISP) within 1/4 mile of all the existing WISPs towers.  I ended up
attempting to help the existing WISP but was unable to prove anything
besides noisy 2.4 GHz.

They had an open case with the FBI and as far as I know the end result
nothing more than some shoulder shrugging from all parties.  The
interference eventually went away (or at least was minimized.)

That existing WISP was just sold a few months ago, and I have
customers running from both of them to my service, so I guess it
worked out well in the end for me :)

Re: [WISPA] Reverse DNS troubles

2007-09-04 Thread Graham McIntire
A quicker workaround than convincing your IP provider to set the
reverse for you would be to use a remotely dedicated or co-located
server (or even a cheaper virtual server) to bounce all of your
outgoing and incoming mail through.  That way you could set up
something like mta.yourdomain.com forward and reverse, which all mail
will pass through both incoming and out to make the overzealous spam
filters pass the mail.

Re: [WISPA] Nstreme2 Link & Pacwireless

2007-08-01 Thread Graham McIntire
I have a VIA Epia M1000 with a DC-DC 12v power supply.  If I recall
correctly, it drew 17 watts @ 12v with a RB24 card in it.  Although I
haven't done it, there shouldn't be a reason you couldn't run that off
PoE with a "reverse-injector" on the motherboard side to take the
power off the cat5 before it gets to the board.

The newer DC-DC power supplies (
http://www.mini-box.com/picoPSU-60-WI?sc=8&category=13 ) are probably
much more efficient than the older one I have.

copper wire.  The bearing was for a mast I don't use, so I was able to
mount it on the very top of my tower since it already had the mount
for it there.  It's only grounded to the tower metal itself and has
been up for a little over a year.  I haven't blown a radio on that
tower yet, so I presume it's doing the job... we've had plenty of
lightning storms come through this year.

You have to classify a specific area of business you operate in if you
file for a Sales and Use tax in your area.  I'm in an unincorporated

Re: [WISPA] Reverse lookup

2007-07-12 Thread Graham McIntire

I'm running BIND 9 on all my servers.  I think classless reverse
delegation was supported in earlier versions, although I can't say
I've tried.  RFC 2317 has been around for a while:
http://www.faqs.org/rfcs/rfc2317.html

I didn't know it was possible either until I got the /25 delegated to
me and I had to figure out what zone it was coming to me as.

I don't think BIND can handle smaller allocations. You may have to
pretend to be authoritative for the whole /24. (Your upstream will,
presumably, only route requests for your /28 to you, so the only folks

Re: [WISPA] Alvarion VL on AM Tower

2007-07-06 Thread Graham McIntire

Correct, ideally you should place one at each end of the cable, right
before it's terminated.  They just clamp over the cable itself and
help reduce spurious RF by turning it in to heat before it gets to
your equipment.

If you're need to chock the cat5 and power line, I'd use a single
ferrite choke at the end of each cable (they're cheap).  That should
help cut down substantially on outside interference on the cables.

So that just goes around the outside of the cable, like they have on

Re: [WISPA] 5 GHz attenuation

2007-06-22 Thread Graham McIntire

The CPE is a LiteStation5 running OSWave firmware (stock LS5 firmware
did not work with Routing/Nat/DHCP), in a 23 dBi ARC Wireless antenna.

The trees around here (NE Dallas area) are some pine, oak, pecan, locust, etc.

Right now the trees are a little damp from a ton of rain the past few
days.  Signal levels for the 3/4 mile link with ~1/4 mile trees is:
-69 dBm Rx at the CPE
-72 dBm Rx on the tower

Without the trees that link would be WAY higher than that.

I also have a client about 2.5 - 3 miles away NLOS (maybe 1 or 2
treelines) that sits around -80 dBm on both sides.  He's been up for
almost a year and I don't think it's ever dropped from attenuation.

Right now 100% of my clients are on 5.8 GHz.  After working with it in
the field for a while I can vouch for it being one heck of a tricky
animal.  Links that look perfectly fine in radiomobile just flat out
don't work, and others that RM shows will never work haven't even
dropped a single time since they've been up.  I just started adding
900 to my towers so I don't have to brute-force my way through iffy
links with higher power on 5ghz.

The town is basically a square with the tower on the far west side in about
the center.  It is 1/2 mile to the extreme corners, so there are a lot of
people 1/4 mile and less.

Someone on another list mentioned water retention as a show-stopper, but my
limited experience had me thinking just about anything less than a 1/2 mile
would work.

Re: [WISPA] 5 GHz attenuation

2007-06-22 Thread Graham McIntire

I have two towers running MT APs at 5.8 with CM9s and 16 dBi horiz
sectors.  Using Osbridge 5GXi's as the CPE, I have clients a few miles
out with non-LOS and the occasional treeline without any issues.

I also have one house about 3/4 mile away from my tower that's going
through nearly 1/4 mile of scattered trees.  It attenuates pretty
badly during heavy rain until the leaves on the trees dry out, but
stays connected.  It's my parents-in-law's house, so they're a little
more forgiving if it happens to drop than a client would be ;)

Half a mile with scattered trees shouldn't be a problem for you, even
with snow/rain attenuation.

I have a 5 mile link where I'm not quite sure if the antenna is above the
trees or not as it is on top of a mast.  That link is on the better side
of -80 for almost 2 years.  Based on that I'd think I'd be okay at a half
mile or less.  I figured that with most of the town at better than -60 and a
lot better than -50, I could stand to go through a few meters of tree, but
that's why I came here to ask.  ;-)

Based on the numbers on the site I looked at, 10 db of attenuation is 27' of
foliage.  That'd put 20 db at 55' of foliage.
