Re: [WISPA] Can 900MHz do this?

2011-04-14 Thread John Valenti
hi Greg,

I see you have several other responses, hopefully you'll get a solution.

I would just caution you about assuming it will / won't work in your situation, 
until you try it.  (I realize you can't really try it without the equipment)

I'll just give one example from a few years ago: I was trying to make a 
connection using Trango 900. No hills were involved. I had an AP mounted 80' up 
on a silo and a potential customer  1.25 miles away. It wasn't particularly 
dense trees, I had made other, longer connections that seemed much more 
difficult. I fiddled with things for several weeks and could never get a 
reliable connection there. (signal was ~ -90)

[WISPA] Spectrum Bridge whitespaces webinar now on Youtube

2010-11-04 Thread John Valenti
FYI
I listened to this webinar last week , they have now loaded it on Youtube.
http://www.youtube.com/spectrumbridge

The best news I picked up from it was that they expect hardware to be available 
early second quarter 2011.  I hope that is accurate, I was afraid it would be 
much later.

Re: [WISPA] Changign DHCP timeout XP/WIn7

Justin,
I don't quite understand what you are trying to do, so I can't offer 
suggestions. Can you elaborate?

(I use a Mac generally, and have that configured with several profiles. But 
sometimes I use Windows, I know that supports profiles but I've never bothered 
setting them up.)

Re: [WISPA] Changign DHCP timeout XP/WIn7

2010-08-20 Thread John Valenti
Justin,
I would think you would want to have it setup to just switch quickly to a 
static address via profile or script or something.

But perhaps another solution would be to use a switch or hub? If your windows 
computer is plugged into that (rather than directly into a radio), it will keep 
ethernet carrier and not want to look for a new address every time you switched 
radios. So it would just keep using the autoassigned one. (I think)

I don't use Mikrotik much, I vaguely remember it uses a program that manages 
radios without using IP addressing? Perhaps that is why your auto assigned 169. 
address is of any value. Almost all the radios I've used (Trango, Tranzeo, 
StarOS) you have to use a specific subnet (not auto assigned) to talk to it. So 
I started out with a system that let me rapidly switch between a few statics 
and dhcp.

Hope that helps. 

On Aug 20, 2010, at 4:01 PM, Justin Wilson wrote:

The whole thing is windows takes so long if there is no DHCP server 
 available.  For example, plug into a fresh Mikrotik with no configuration.  
 How long does Windows take to time out if it is set to DHCP?  I have timed 
 this at 1.5 minutes.  My mac only takes 17 seconds to say “hey there is no 
 DHCP server I will auto assign a 169 IP”.  What I am looking for is a way to 
 tell Windows don’t wait 1.5 minutes before you assign a 169 IP.  Only wait 20 
 seconds or whatever.
 
 Sure you can assign a static IP and lessen this time, but assigning that 
 IP takes time to do and undo. 
 
 The best solution I have seen so far is Barnes’s suggest for a program 
 that lets you change networking profiles.  I was hoping someone knew of a 
 registry key you could edit.  Something like DHCP_TIMEOUT=20s.  Instead of 
 DHCP_TIMEOUT=120s.

Don't know if this is possible at your site, but can you add a second AP?  Just 
switch polarity, channels and try to separate the antenna by 10'+
Then start moving clients over until you have them ~50/50.

Good luck.

 We run the Tranzeo 902nf radios as APs and the most we can get on them
 is about 10-15 clients.  After that performance declines rapidly.  How
 you ever got 50 on there is amazing.  We have since moved to a MT AP
 using a zcom gz901 card, and the performance has been much better.
 Tranzeo radios just never scale very well.  Had the same issues with
 their TR-6000 2.4 APs.  I would reduce the client count down to 20, and
 see how the performance is.  What are you seeing on the stats page under
 the UMAC tab?  Percentages of failed packets?  Do you have a hard time
 getting to the web interface for the AP?  What firmware version on AP

Re: [WISPA] 5MHz Channel Drawbacks?

2010-05-10 Thread John Valenti
I use 5MHz channels and like them.
One thing I have worried about, but maybe hasn't been a problem: if someone 
else is scanning for regular WiFi channels, they won't see my 5MHz ones. So 
they might pick a channel that overlaps my gear.  Generally my S/N ratio is 
high enough that I haven't noticed this being an issue.

Oh, another minor issue is that I don't have a laptop that works with 5 / 10 
MHz channels. So if I pull up to one of my grain legs, I have to setup a radio 
and work thru that. It would be nice to have a regular WiFi channel at the 
tower for convenience.  The StarOS people do have an Atheros driver that 
supports 5/10MHz channels, but my favorite laptop doesn't have an Atheros 
radio.

[WISPA] Verizon fiber

2009-10-28 Thread John Valenti
I'm assuming this is hopeless, but somebody here can probably confirm:

Verizon has fiber running down the dirt road that passes by a grain  
leg I'm using. (I'm told it was put in for 911 service to Bath, MI) 
Is it possible to have them tap into it and sell bulk bandwidth to  
me?  For less than 10s of thousand$?

If it helps, there is a small concrete vault nearby that the fiber  
runs thru. The farmer says the cover has been left open on that for  
years. You can look in and see a metal can (about 8 by 2') that the  
fiber runs thru.

 so with current OFDM technologies you can get 10 - 12 Mbps on a 6

Re: [WISPA] Holy cow!

2009-10-23 Thread John Valenti
Mike,

First, take everything I saw about this with a grain of salt, because  
I'm no expert.

 From my reading of the RO, there are two types of whitespace device.  
There is a low power version, that I think is intended to be like a  
mini-PCI card, installed in a laptop. There are no height restrictions  
on that.

Probably of more interest to us are the higher power devices (up to 4  
watts, I think). Those are limited to antenna heights between 10 and  
30 meters. I don't think the AP is special, it also has to be minimum  
10m high. So it couldn't be on the ground.

Personally, I wonder about this 10m minimum. Since all the devices are  
networked, I would argue that maybe 50% of an APs clients could be  
lower. One of the higher radios could pick up a new tv signal and  
force the whole AP to move channels. That would avoid the silly  
looking large antenna 15' above a single story ranch house roof.   
Perhaps if this stuff takes off, we could argue for that in the  
future.  (or maybe I'm all wrong, since I'm more a software guy)
-John

 Thanks guys for sharing the height thing.  Such restrictions on the
 production plan won't work.  If the goal is to allow such use in an
 urban setting, the modulation technique would have to be able to
 survive severe multipath.  I'll have to think about the AP on the
 ground and the client on the roof.  Does that make sense?  It would
 certainly keep interference to the AP down.

Gino,

I'm not so sure about this  if it is going in a rack, seems like  
it might be worthwhile to get a higher performance CPU with more max

And for a box at the base of a tower, seems big and hungry (200W AC

Could you compare it to:

Apart from being single core and out of stock, this one takes 12V

DIN rail.  Maybe $200 for all the parts. I was thinking of using these

You wouldn't need a NIC unless you want dual ethernet (comes with one

But you do need to put in a stick of laptop memory and a boot device.  
Maybe USB flash, IDECF or SATA DOM, because the CF slot is hard to  
get at.
Oh, the one I have says 19V DC power brick, so I don't think you could

Re: [WISPA] Nice unit for POP Router / Appliance

2009-07-28 Thread John Valenti
Oh, Josh, just realized that MSI Wind computer has no PCI or PCIe  
slots, nor ATA. Anything you add to it would have to go into  USB,  
SATA, CF slot or miniPCI express slot.  So it would be harder to add a  
second ethernet to this version.

If you want to route, it would either be USB ethernet or VLAN.

Is routing via VLAN common?  I have heard of one-armed routers, but  
didn't think they were too common.

Re: [WISPA] Nice unit for POP Router / Appliance

2009-07-28 Thread John Valenti
Gino,
How many ports?
What have you found for PCIe ethernet?  A quick look at Newegg for 4  
ports only shows Intel, at $400. So the ethernet card costs more than  
the server.

If you stick with PCI (other Atom motherboards) you can use the  
cheaper Mikrotik 4port gigE (~$90).  Total build cost might be less.

 Could you compare it to:

 Apart from being single core and out of stock, this one takes 12V

Jeremy,

Since you mention StarOS, I have to ask:  why not just use the Lucaya  
gear?

If you skip the amps, the X2000 would let your climber take up a  
replacement radio and change two RF cables and one ethernet cable.   
(for two radios)

Just curious why you seem to reject the StarOS preferred hardware?

Re: [WISPA] Cost of 900 MHZ CPE

2009-06-05 Thread John Valenti
I agree with your sentiment that 900 stuff is too expensive.
But I was pleasantly surprised. while looking around DoubleRadius last  
weekend, to see Tranzeo TR-SL9 client radios for $234. (8dB or N  
connector, take your pick).  I missed any announcement of them.

One could hope that a multipack of those might get under $200 each,  
later this year?

-John

PS - not to be a Tranzeo shill, but they are also running a special on  
the expensive version of 900 AP this month.  $300 gets you ssh access  
into the AP, woo hoo!  Has anyone tried these SlimLine or EL radios?

Re: [WISPA] 2nd Look @ 3.65 ?

2009-03-19 Thread John Valenti
Marlon,

I watched the tranzeo wimax 3.65 webinar a few weeks back. They have  
that pico base station for about $1700. I asked, and they said yes, it  
would work with an omni. I know everybody says don't use an omni, but  
maybe it would be OK on 3.65?

I was curious because most of my grain legs would max out at 20  
customers (due to trees). And I certainly wouldn't want to buy three  
sectors just to support 20 houses.

They do have a starter kit that includes two(?) customer radios for  
free.  I'm out of money for testing things, but let us know if you try  
it.

Re: [WISPA] first whitespaces 802.11 card?

2009-02-25 Thread John Valenti
Brian,
Like Jack says, this is nothing like a whitespaces device.
You can download the first draft of the specifications at the FCC, I  
think it is about 120 pages.  The devices are supposed to have a  
sensing radio to detect existing tv channels, in addition to detecting  
wireless microphones, and then shift to another open channel. And it  
is supposed to go over the net to query a database (that doesn't exist  
yet) as to what channels are open in a given area.

Also, you ask about what antennas are available. Speculation was that  
you would buy a radio and it would be certified with a specific  
antenna. The certification requirements will be much stricter than the  
unlicensed gear we are familiar with. And I would suspect the tv  
people will be looking over your shoulder, making sure you follow the  
letter of the law.

Also, I believe the channels available in a given area are still  
somewhat in flux. Many stations were going to move around on the  
transition date, now that is delayed. I don't think the database Brian  
queried to build his google.kml has the final data.

Like Jack suggests, you really need to check with Verizon.

I'm pretty sure there might be potential features that Sprint has  
turned on for that phone, that would prevent Verizon from working with  
it.  For instance, I had an older Verizon phone that didn't include  
location features and Verizon refused to turn it on.  (even though the  
phone I was using was even older and didn't include location tracking  
either)

Eighteen months ago Verizon said they were moving to a more open

yet.

[WISPA] Tranzeo TR902 missing features

2008-12-15 Thread John Valenti
I started using Tranzeo for 900MHz a few months back. When they work,  
they seem to do pretty well. But I'm having trouble debugging them.

I haven't found a method for the following, maybe I'm missing something?

- login to the client (or even AP) radio, use ping to check  
connectivity out to the net
- requires web interface, so I don't have any method to connect thru  
the AP to the client when using NAT (ssh?)
- ping watchdog feature
- bandwidth test between the AP  CPE

My other radios are mostly StarOS, so I'm spoiled by the more advanced  
features.

One nice feature of this Blockbuster device is that it seems to  
download and store the video, so it doesn't rely on streaming.
Also, I looked at their website and it seems like the good videos  
cost $3.99 (not 1.99). The videos did seem to be more recent than the  
ones Netflix offers.

 I sure wouldn't bite.  8.99/mo + Internet for unlimited or 1.99 +

Re: [WISPA] Customer issue - data stream halts, can't email

2008-11-24 Thread John Valenti
Josh,

Can you have the Mikrotik ping your core?  (it sounds like you have  
only done the other direction)  Also, try full size ping packets.  
Sometimes short packets are fine, and big ones cause failures.

After having a batch of bad consumer wifi routers, I have started  
hooking up a few people directly to the radio (if they don't need  
wifi).  One less thing to fail.

Do the Trango linktest utilities check out OK?

Finally, the problem could be her computer. I suppose it is windows?   
Virus scan, etc but personally I don't trust *any* windows computer  
that hasn't been freshly installed.

Re: [WISPA] Updated White Spaces mapping tool

2008-11-24 Thread John Valenti
Brian,

Thanks again for this!

A few comments:
(1) I was surprised to see channels 3  4 included, since those are  
prohibited everywhere (right?)
(2) you might include a note on your web pages about the 32km canadian  
border limitation, also the 40/60km Mexican border limit.
(I'm guessing that would be hard to include as an overlay)
(3) I found a list of the 13 metro areas limited for PLMRS/CMRS  
operation at http://edocket.access.gpo.gov/cfr_2002/octqtr/pdf/47cfr90.307.pdf 
  (2 page PDF).  For my situation, Detroit has channels 15  16, so  
channels 14-17 are off limits out to 134km, I think.

I was also able to use the analog file after a few attempts. (I turned  
on everything and locked up Earth the 1st time)  Do you know of a  
method to click on one of the analog overlays and find out what it  
is?  I see there is one in the next county over, but I don't really  
want to go thru that long list and turn them on one at a time.

Oh, is it OK to point other people at your tool?

thanks again!

PS - your webserver has a great connection, I had that 20MB file in  
about 30 seconds.  :-)

Where are you reading this on page 43?

And I've made it farther back in the report...

Is Appendix B (Final Rules) the actual rule?   That doesn't look good,  
see Antenna Requirements on page 101. Not only is the transmit antenna  
limited to 30 meters high, but the receive antenna must be 10 m high.  
Sounds like a single story ranch house is going to need a mast.  That

Also, it sounds like a yagi isn't acceptable as a receive antenna:   
The antenna system shall be capable of receiving signals of protected

Re: [WISPA] TV Whitespaces PtP Backhaul

2008-11-18 Thread John Valenti
Could you elaborate on why this is a bad idea?

I'm slightly interested in it for low cost connections.  In my current  
area, I don't have a problem finding grain legs for AP sites. These  
would be dense enough that I could build a great network with white  
spaces cells and 5GHz backhauls.

But if I look farther north in Michigan, the forests are denser and  
the grain legs disappear. The terrain is flat enough that I can't use  
mountains for cheap tower sites. And none of the 900-2.4-3.65-5GHz  
radios are going thru the trees.

It seems like a PtP backhaul that would work ten(?) miles thru trees  
would be a great cost savings over building towers. Maybe use two  
channels for full duplex. The rural areas that I'm looking at have  
over twenty channels free. (thanks Brian Webster for your kmz!)

Re: [WISPA] coax cables

2008-08-20 Thread John Valenti
Chuck,
Vegetation might have a huge impact on the coverage area.  I've seen  
pictures of your area, it looks like heaven to me.  My experience is  
that the first two trees will eat up a 5.8 signal, so expanding the  
coverage area by 80% just adds another tree or two.

It might be very sensible for Kurt (?) to use the coax rather than  
put a little more signal into a bunch of foliage.

My best experiences have been with StarOS clients connecting to

program the client radio's ping watchdog to hit the AP every 10  
seconds. Then when I'm in the association page on the AP, all the  
clients will have less than 10 seconds since they have passed  
traffic.  Any clients that have a minute+ in the far right column get  
some attention to figure out what is happening.

Re: [WISPA] 3.650 Wimax in the field

Mike,

This does seem to good to be true. Could you provide more details on  
these links (for instance, tower heights, or maybe even coordinates  
that I can look over the path)?

I was at a roadshow earlier this year. A Redline rep was there, he  
said that 3650 wasn't all that great thru trees. Maybe a kilometer.   
And Ball State U did a research study using 3.5GHz, they had spotty  
results starting at 3/4s of a of mile.

You say these tests were in Ohio, that would seem to be pretty close  
to Michigan in tree foliage and perhaps topography.

These are the sorts of results I've dreamed about, but can't really  
believe are possible. I was pinning my hopes on whitespaces radios.   
If you arrange a demo, I would love to drive down and look things over.

Also, you mention a PC card ... is someone making a wimax card in 3.65?

 With some of the Wimax discussions going on I thought I would throw
 my hat into the ring.

 3.650 Wimax using 802.16d only products provides decent connectivity,
 at a higher cost than traditional unlicensed
 gear.  Performance/coverage is on par, or better than 2.4 that most
 of are used to.  Pay a little extra for product, gain access to
 cleaner spectrum and hopefully a rule set that helps keep it cleaner
 than our wild wild west unlicensed world.

 Now deploy 3.650 using 802.16e upgradeable products.  The coverage
 difference when using diversity options goes up significantly.  Now
 3.650 begins to act and feel more like a 900Mhz product with NLOS
 coverage capability.  Actually our customers, and our field tests are
 showing that it exceeds 900Mhz often by a large margin.  Here are a
 couple recent field examples all 2nd order diversity:

 Customer 1- 8.4 mile NLOS location. blocked by heavy trees .  1.5MB
 download holding CPE in their hand on the ground!  Decided to test
 5.8 at this location and @ 50' AGL the CPE got a link.  5.8 mounted
 on the same tower, same height as 3.650.  The 5.8 system could not
 pass data and could just barely maintain association.

 Customer 2- 12.4 miles away at the owners home.  1.0mb on the
 ground.  This location could not be serviced by 2.4 or 5.8 at 40'
 above the ground previously.  The owner is going to mount Wimax on
 the roof and I expect he will se 10-12MB at that height.

 Customer 2- 12.6 miles on the ground.  Completely obstructed 6MB  
 down 3MB up.

 Customer 3- This is one of the most telling.  Canopy 900
 operator.  3.650 2nd order diversity mounted 10' below Canopy.  100%
 coverage at 3.650 of a small city.  It takes 2 tower locations
 with  900 here to serve the same area.  They gave up field testing
 because it works everywhere.  They the said lets try to break
 it.  We drove to a part of town that is challenged with 900
 coverage.  They found a traditionally bad coverage spot and drove up
 to a big tree, took the CPE out of the vehicle and buried it in the
 tree.  -101 signal.  They then picked up their VOIP phone and called
 the NOC and did a can you hear me now?  Toll quality voice call.

 Our internal testing is showing similar results. Using 4th order
 diversity is showing even better results than above.  When you do the
 upgrade to 16e and add Wave II CPE, Katy bar the door.  That coverage
 is nothing less than jaw dropping.  2.5 miles obstructed with a PC
 card!  Same PC card 1 mile away entering a commercial building, no
 signal change.  Not possible with a traditional system.  In this case
 the wall measured a 25db loss, however STC and MRC diversity gains
 completely made up for the attenuation once the paths became  
 uncorrelated.

 Bottom line is diversity is the place to be with Wimax.  It is more
 expensive, so find a way to afford it.  Push your vendor for price
 breaks and don't be bashful.  Alvarion for example is willing to work
 to earn business as well as the others.  CPE costs for D and E
 systems are the same today, E will be much cheaper in the near
 future.  Not all Wimax is the same, so test a site or visit one, you
 will walk away amazed.

 My two cents, and we carry all D and E products.  Each has its place.

Re: [WISPA] UL 1Gbps Link

2008-04-30 Thread John Valenti
It won't get you to 1Gbps, but Trango has their Giga links on sale  
for about $10k.  That is 100Mbps full duplex, then another $1500 gets  
you a software upgrade key to 300Mbps full duplex.

That would be a licensed link at 18GHz.
(let us know what you end up with)

Re: [WISPA] Paging

2008-04-29 Thread John Valenti
Patrick,

I don' t know if this will help, but it is possible to give your  
Verizon account a nickname. Then messages would be sent to  
[EMAIL PROTECTED] Possibly that would have different rules for  
filtering out spam?   (just speculating, I don't know)

My problem was the opposite, I was getting quite a few spam text  
messages last year. It has declined, but I still get a few. It was  
annoying, at 15 cents per message.  And Verizon wasn't too helpful  
when I complained, they wanted me to call and ask for a credit.  My  
planned solution was to disable the numeric version of incoming text  
messages, and switch things over to the nickname. But they dropped  
off to one every two weeks, so I'm just ignoring them.

Oh, do the providers like SiteUpTime have a special agreement worked  
out with the cellcos?  I get alerts from them for servers down,  
perhaps there would be some means of routing traffic thru them.

[WISPA] Internet Outage / South Park episode

One of the Chicago Tribune bloggers discusses an outage at his house  
in this posting:

He includes a clip from South Park that I gather is recent (we're an

I think many on this list will appreciate it; and help understand the

Re: [WISPA] RSTP problems with simultaneous WiFi + wired connection

2008-04-21 Thread John Valenti
I'm not sure what RSTP is and don't want to research it currently,  
but I can tell you about one painful scenario:

a few years ago, Thinkpads (might have been IBM, or maybe it was just  
after the Lenovo change) shipped with some software that offered to  
help you manage the wireless networking.  If the laptop was plugged  
into ethernet and then joined a wireless network, it would offer to  
bridge the connections. Saying yes would create a packet storm on  
our building network.

We had a few of the storms over several months. It seems like that  
bridging option was dropped from the Thinkpads eventually (or you  
could switch to windows zero config and avoid it).  Maybe do a search  
on arp storm, I think that is what was happening.

 And the agency will break out five speed tiers in its upcoming

Re: [WISPA] Off Grid System Design Comments.

I think Paul Gipe is a respected name in wind. I was looking at his  
site over the weekend, he has an older review of the Air-X, he seemed  
to think it should really be rated as a 200 watt generator.
http://www.wind-works.org/articles/sm_AirXtest.html
(I see the company has a newer model out now called the Air Breeze,  
rated at 200watts)

He also links to another test site: http://www.detronics.net/ 
airx_report.pdfThey have another report that lists the advantages  
of running a combination of wind+solar to balance things out over the  
year. But I think this is highly variable, depending on an area's  
sunshine and windspeed.

Lucaya has complicated things for me by requiring 48V on their new

Does anyone know about the Powerstream PST-DC2448 (converts DC 24 -  
48V)  http://www.powerstream.com/dc12-48.htm

Or suggestions on other reasonable ways to keep radios running for

Re: [WISPA] pcb

2008-02-18 Thread John Valenti
Tom,

One thing I did when I was building StarOS radios was use one  
mounting screw per board. Partly I was doing that because I thought  
the board should be grounded to the case, but it also would have  
helped if the glue failed on the plastic standoffs.

Also, I'm not sure what the bad effects would be if the glue failed.  
The standoffs would prevent the board from shorting out on the  
bottom, enough other components would prevent it from shorting on the  
top (probably).  The stiff ethernet cable would sort of keep it in  
position.  (in a DCE anyway, maybe a Rootenna would provide too much  
wiggle room)

But I didn't build enough of them, or have them in service long  
enough to draw any conclusions. Or rather, I came to the conclusion  
that I hated u.FL connectors; and assembled Lucaya M1208 radios were  
way better!


On February 17, at 6:24 PM February 17, Tom DeReggi wrote:

 Well, I guess an alternative is that if Plastic cases are used,

[WISPA] Small generators - cheap or inexpensive?

2008-02-18 Thread John Valenti
I was looking around for a method to keep at least my backbone  
running during an extended power outage. (we have had ice storms take  
out power for 4 - 7 days).

It seemed like the small generators might be a solution, the Honda/ 
etc name brand ones seem to be ~$600 for 1000 watts. And I found a  
company that sells Yamaha 1000W generators converted to dual fuel (NG  
or propane) for about $1000.  They also sell a 2400 watt generator  
that is triple fuel, gas/NG/propane that is tempting, even at $1600.

But then I ran across some imported 2 stroke, 1000 watt generators.  
Harbor Freight has them in their catalog for about $150. I found a  
similar one in a local store that is on sale for $99.  The box says  
it will run for 8 hours on tank of gas (at half load, 1.25 gallons).

These imported ones just seem like they are too cheap.  And I'm not  
too fond of 2 stokes. That Yamaha dealer warns that the cheap  
generators are only designed to last 150 hours - but maybe 150 hours  
for $100 isn't too bad a deal.

Just wondering if anyone has thoughts or experiences on this issue.
thanks

Re: [WISPA] Small unmanaged switches

2008-02-15 Thread John Valenti
I would just warn you away from the NetGear GS108.  I only had one,  
but it locked up repeatedly. (sitting in a phone closet) Comments on  
NewEgg claimed that model had the bad capacitor problem (I just had 2  
Dell motherboards replaced for that) - but I haven't opened up the  
switch to look at it.

Otherwise I would say my sample size is too small to make any  
predictions.  I am using some Dell PowerConnect 2708 gigabit switches  
(about $80 on their small biz site) that have been fine. One of those  
is in a metal box 130' up a grain leg and has survived the winter so  
far ( knock on wood  -10 F min to date).  They have a web interface  
so you could ping monitor them.

Oh, HP ProCurve 4000M switches are neither small nor unmanaged. I've  
had uptimes of ~2 years on those. About $125 used on EBay.

 Netgear FS105s and the big brother FS108s run about 3/4 of our

looks like.
General results were that the boards will handle 30meg in both

speed, the other end will do more traffic, and that split seemed to  
max out at 50meg in one direction and 15-20meg in the other.   I  
didn't get any speeds faster than 50 meg.   This was using standard  
20mhz channels.  40mhz channels didn't seem to do much better as  
the CPU was maxed out.  I'm curious to see what kind of results  
could be obtained with 2ghz CPU units on both sides using the 40mhz  
channels.
For a $400 unit, I think this is outstanding performance and they  
are very versatile.   I have several up as backhaul links (in  
regular HDX mode) pulling 25-30 meg at distances of up to 30  
miles.   I even have one set running on a 62 mile shot that will  
pull 10-12 meg consistently.   They are also great as 5ghz or  
2.4ghz access points.   We have one that has three 2.4ghz sectors  
on it and 120 clients between the three sectors.   The board is  
doing an outstanding job and very clearly outperforms the three

Here is a link to the Lucaya store:  http://www.station-server.com/

I have also heard that Streakwave will be carrying this product as

Re: [WISPA] brain cramp, can someone jog my memory?

2008-01-02 Thread John Valenti

Wow, thank you!
(really meant to send that message directly to you, but now the list  
can see your plots, too)


It is flat here, but the trees are the problem for RF.

Do I understand the last plot correctly: that ignoring trees, a  
2.4GHz signal would work for ~12 miles?  Amazing.


I feel lucky when I can get a 2.4 customer connected at better than  
-80, and they are usually within a mile of a grain leg.

I used a 200 mw radio and a 23 dBi panel antenna (like the

Of course the Alvarion units would be the choice if you had the $$.

Re: [WISPA] brain cramp, can someone jog my memory?

2007-12-28 Thread John Valenti

Say Ralph, I don't suppose your offer extends to others?

I've looked at Radio Mobile a few times, but didn't want to invest  
the time to figure it out.  My current method involves using google  
earth, drawing a line between the two points, then sliding the cursor  
along it to see elevations (while sort of watching the vegetation).   
Not exactly scientific!


If you don't mind doing a path analysis for me, here's one:

Site A:  42°55'59.62N 84°14'55.80W   I'm using a grain leg here.

Site B:  43° 0'15.15N 84°11'37.26W   ( I can get a gigabit  
ethernet connection here -- well, could only afford 5Mbit, but  
still ...)


I would need to build a tower at site B, but how high does it need to  
be?   It is only a 5.5 mile jump, and the elevation doesn't change  
much, so I would think 70' might work (enough to clear the trees,  
plus some). The grain leg is about 80', the connection would be  
5.8GHz.


If you would be willing to run Radio Mobile with this, I would love  
to see the results. Might encourage me to spend more time with it.


And if not, well thanks for your time and happy new year!

Re: [WISPA] Which UPS to use?

How much effort is involved in changing it over to the RV batteries?
You need to use two of them because that is what the SU700 is setup

It seems to do OK charging these batteries that are considerably

Is the SU700NET the cheapest APC that accepts the smartslot cards?

Re: [WISPA] Ubiquiti PS2 -- StarOS v3

2007-10-29 Thread John Valenti

Mark,

What don't you like about the Lucaya enclosures?

I have one of the 1208 versions to evaluate. I think I like it a lot.  
The built-in antenna seems like it should be good enough for LOS  
customers out to a mile, and with our trees few people would have LOS  
beyond that anyway.


If I want to use a stronger antenna, I can plug in a VAGI (that's  
what I'm leaning toward currently).  And I can set that H or V  
polarity as desired.


I should be able to just stock this single radio and be fully covered  
for clients in 2.4GHz.  Near as I can tell, it is slightly cheaper  
than the Rootenna parts, arrives ready to install, and is FCC certified.


I do like the small Rootenna, but realistically I spent several hours  
over the weekend putting together just 4 systems (and then testing  
them). I would be happy to never need to connect another ufl  
pigtail!   Just testing the Roos in my basement, none of them worked  
as well as the 8dBi Lucaya unit.

[WISPA] RF propagation map: WiFi vs WiMax?

2007-10-04 Thread John Valenti
Just curious if anyone has seen a coverage map that compares WiFi and  
WiMax?


I spent a little bit of time researching WiMax, but decided I would  
be unlikely to have a license and to just go with what I have that  
mostly works (unlicensed). But I would like to know what WiMax means  
in a rural, tree filled environment.


As a novice WISP (about 18 months now), I can only hope for good  
coverage with 2.4GHz to maybe a mile. A rare house might have LOS  
farther than that, but generally there will be enough trees in the  
way by a mile to block my signal.  (this is using farm grain legs/ 
silos for the AP, so maybe 150' max AGL)   If I switch to 900MHz,  
maybe the distance gets out to 2.5 miles.


Would a 2.5GHz Wimax AP push the signal much better thru trees?  I  
suppose it would make a difference what was at the customer end - a  
laptop with a WiMax card vs a fixed, outdoor radio.  And does AP  
height help a lot?  I don't see an advantage to paying commercial  
tower rates to get above 200' in my situation, but maybe that changes  
with WiMax.

[WISPA] 900MHz consumer items

Re: [WISPA] Thoughts on 900MHz mesh networks

2007-09-10 Thread John Valenti

Allen,

It sounds as if you might be proposing this for a suburban or even  
tree filled urban environment. One problem you might run into is  
clear spectrum in 900MHz.  I've use Trango gear out in rural areas,  
where it works OK. I've only done a few scans in the city (East  
Lansing and Lansing, specifically). Both of those scans were so  
depressing I never tried making any links with 900 in town. All the  
channels were what the Trango manual calls unsuitable.


I have a few of the SR9 cards and am just starting to work with them.  
I read somewhere that Trango (for example) rejects interference  
better than the SR9. No personal experience one way or another yet.


My new rule of thumb with Trango is that I can go 2 miles.  This is  
with AP's at 80 - 130' AGL, pretty flat ground, but quite a few  
trees. However, I have been struggling to make a link that is only  
one mile, unfortunately the path follows a heavily wooded riverbed.  
So you just never know. I think I've solved this connection by  
relaying off the house next door (tenth of a mile closer, but with an  
open field for 1/4 mile toward the AP). But I did notice that there  
is heavy noise at the relay house in what Trango calls channel 2.   
Noise level about -67. No idea what is doing that.


You might consider a modified mesh structure that uses 2.4 or 5GHz  
(or even 900 after testing) to those few LOS houses, then something  
like Meraki mesh to connect close neighbors.


Otherwise, I think your idea is great, if you could get clear  
spectrum.   :-)



On September 10, at 12:16 PM September 10, Allen Marsalis wrote:

Please imagine a muni wireless mesh network that utilizes 900MHz

apart.  Instead of it taking 15 or 20 nodes to cover one square  
mile, perhaps one node could cover 1 to 4 square miles.  Could this  
be a solution for wooded areas with low to moderate population  
densities?  In other words, do you know anyone who has ever built a  
mesh network using SR9s and SBCs with multiple radios to achieve  
redundancy and ubiquitous coverage for small towns in the  
Southeast?  And using no towers by the way, LOL?  As I see it, the  
SR9 has 4 non-overlapping channels at 5MHz each.  Thats all I need.

This is totally in the other direction of having a full keyboard, but

Technically, I don't see how you can track IP address location very  
easily. I don't look forward to a government mandated system that I

We still have a landline at our house, but never use it. I would cut

I did a few tests at the East Lansing Starbucks. I start the call on  
WiFi and walk out the front door. By the time I'm 20' away it has  
switched over to a tower. I didn't detect any noise during the  
switch, but I was outside next to a 3 lane road.


Unfortunately that doesn't work at my house. If I move out of Wifi  
range (currently about 20' from my porch for this phone), it drops  
the call. I need to move about 7 miles before I can reliably hit a T- 
Mobile tower.


The Starbucks has a T-Mobile Hotspot, the phone usually automatically  
switches over to WiFi there. (I think that is how it is supposed to  
work) Still a few bugs in the system: sometimes I have to use the  
phone menu to search for WiFi at Starbucks, then pick the Hotspot. It  
automatically connects, don't have to enter a security code or  
anything. And rarely I have to power cycle the phone before it will  
connect via WiFi.

[WISPA] T-Mobile [EMAIL PROTECTED]

2007-07-20 Thread John Valenti

T-Mobile launched their [EMAIL PROTECTED] service at the end of June.

I picked up one of these cell phones a few weeks ago. The deal is for  
an extra $10/month, you get unlimited calls in the US if they are  
made over wifi. The wifi connection generally works with any open AP,  
or if you know the security key you can enter that. It also  
automatically connects to T-Mobile Hotspots, such as might be found  
at Starbucks. Once you start a call on wifi, you can move out of wifi  
range into tower range it seamlessly switches over. The call is  
billed according to where it starts.


I had actually sampled a T-Mobile phone, then returned it the day  
this [EMAIL PROTECTED] service launched. Most of the places I hoped to use  
it, I had no signal. But I like this new combo phone quite a bit.


For example: my WISP office is in my basement. I've used Verizon cell  
phones for years, based on having them work almost everywhere I go.  
But no service in my basement.  The T-Mobile phone happily uses my  
net connection and sounds better than any cell phone I have used.  
Ditto for a few locations at work, such as a server room. No cell  
service, but wifi is fine.


One thing I don't like is that the phone doesn't include a web  
browser. If you are at a location that requires agreeing to TOS  
before using the wifi, you can't do that just using the phone.


I've used some other VOIP systems before (Packet 8, Skype, almost  
went with SunRocket - that was close) but haven't really liked them.

An idea for WISPA leadership: think about brokering a deal with T- 
Mobile to expand their hotspots to members POPs. They only have about  
7500 hotspots in the US. For example, there are none in Michigan's  
Upper Peninsula, and the only one in the north half of the Lower  
Peninsula is Traverse City.



Some technical details:

The T-Mobile phone uses technology called UMA to encapsulate GSM over  
IP. The packets are UDP encapsulated IpSec. The call I monitored  
averaged 60 packets/sec. All traffic was to/from one IP address using  
port 4500. Bandwidth used was 9516 bytes/second average. Most packets  
were 158 bytes (the longest seen), a few were 142, and occasionally  
60 bytes.

[WISPA] MDU info?

2007-06-18 Thread John Valenti
I'm hoping someone here can point me to good info sources on MDU  
networking.  (I did a quick search and didn't find much specifically  
on multiple dwelling unit)


I'm a very small wireless ISP. Right now my Internet source is a DSL  
on top of a city water tower. I'll need more bandwidth in a few  
months, and access to the water tower is problematic (call in  
advance, iffy on weekends, etc).


There is a new loft project in this town (80 res units plus a few  
store fronts), I'm trying to become the preferred ISP for them. The  
builder is running Cat5 to all the lofts, and I could get a fiber  
line into the building and reasonably priced bandwidth. I'm thinking  
a short tower on this 5 story building would link up to a grain leg I  
have a few miles away, giving my wireless net a faster / better  
connection to the net.


My questions are:
	* is it typical that the property owner gets a kickback for using  
his Cat5?
	* seems like the only equipment I would need for the lofts is a good  
switch and a router to handle bandwidth shaping?
	* anything else I could offer that would make my offer more  
attractive to the property manager?


Thanks for pointers to any more details on this line of business.
Sorry to hijack the wireless list...

-John

PS - I have done department level network support for many years  (50  
- 100 computers). And I'm hoping to stay away from phone and video  
service for now.

[WISPA] Re: Mirrored Switch

2007-05-11 Thread John Valenti

(reply to an older posting, I'm trying to catch up)

Matt,

I bought some Dell PowerConnect 2708 switches last fall. That is a  
smaller 8 port gig switch, it was the cheapest one I could find that  
did port mirroring.  About $82 now, go onto Dell's website as small  
business or the price might go up drastically (under the EDU section,  
it was about $100 more).


The 2708 is smaller, I wanted to mount it inside a box up a grain  
leg, so that was what I wanted. They have 16 and 24 port versions.  
All them come with ears for rack mounting. The 24 port one has two  
fiber ports.


I've had one installed at 140' for about two months now with no  
issues.  The other one is in my basement NOC, guess I'll need to move  
that to my other POP before CALEA kicks in.  (ugggh, this weekend!   
time flies...)


-
One concern I had with these is the temperature rating. Only goes  
down to 32 F. But the switches that were rated for colder were much  
more expensive and didn't do port mirroring until $300+.  But I've  
had Allied Telesys cheap switches that are also rated to 32 last thru  
the winter with no problems. (think we hit -20 in February)


That SMCGS24C-SMART that Ty Carter mentions also sounds interesting.
-John

The basic parts you'll need are:
Linux based router or tap capabilities on the on you have.
OR a managed switch that will allow you to mirror a port.


Does anyone reccommend a good switch that supports this and is rack
mount?  Hopefully available at newegg.com.  Putting together a Linux
server is easy but my luck a good switch might be backordered when I
need it.

[WISPA] Useful book from DOJ

2007-05-07 Thread John Valenti
This book showed up in my mailbox at MSU one day. I ignored it for a  
while, but looked it over last week and found some interesting info.  
Probably most useful to a startup WISP, it has some sample subpoena  
(s), court orders, etc.  Basic info on ECPA, etc.


The full PDF is linked from this page:

RE: [WISPA] Using DECT phones to avoid interference issues.

There's a reason you haven't seen these products here.  I began

DECT phones are definitely here in the US. I bought one at CompUSA  
last fall, and I'm sure I've seen then at Staples / Office Max / Best

Maybe the manufacturers have started offering them, now that the per

Re: [WISPA] 3650, ok, so what's current status?

2007-03-05 Thread John Valenti
I heard back from a Ubiquiti salesperson yesterday (working Sunday!),  
they expect to start shipping the XR3 cards this month.


http://www.ubnt.com/xtreme_range3.php4

I guess they are claiming that 802.11 is the contention protocol.

I might check out a pair, we'll see how they are priced. After I  
finish with non-commercial WISP testing, I suppose they could be used  
for amateur radio projects, since they also support 3300-3500MHz.

3650 is complicated.  Last month's FCC visit stated that they are
getting close, and expect answers by Fall :-( Experimental licenses
are available, allthough, would likely result in removing gear in  
a year.


Can you point to any info on getting one?

Re: [WISPA] 3650, ok, so what's current status?

2007-03-05 Thread John Valenti

Jack  Patrick: thanks for all the info on 3650 status.

This type of response is why I'm on this mailing list.

That March 10, 2005 announcement is near-and-dear to me, since that  
is what started me on the WISP path. I haven't closely followed the  
progress on 3650, so when I saw the XR3 info I thought it might be  
happening soon.  Those thoughts were pushed along further when I saw  
the Part-15 org people selling a help get licensed on 3650 manual  
-- their webpage doesn't indicate to me that it is still experimental.

http://www.part-15.org/sales/3650manual.asp

Sounds like I should plan testing under my ham license (~3400MHz)  
rather than clogging up the FCC with a bogus STA application. My  
interest is propagation thru our Michigan foliage, so I would want to  
test this summer. But maybe someone could just tell me what to expect  
- should it be similar to 2.4GHz?


-John  (kd8bqx)

PS - any chance I could convince folks to trim their responses?  I  
read this list in digest mode, 80% of the digest is noise.   :-)


The Ubiquitu XR3 spec sheet is misleading. As far as I know, there  
is no

current legal license-free 3650 operation allowed, as Ubiquity states.
Operation on 3650 can only take place when a Special Temporary
Authorization aplication has been submitted to the FCC and an STA
approval received back from the FCC. In general, STAs in the
Experimental Radio Service are issued to allow on-air testing of
equipment or new technology that can only be tested on-the-air.  
Please

see my previous post which outlines the conditions under which an STA
may be granted.
