This would work, too, although I think it is overkill. Using a sequence of events like: 1. we are connected via radio1 with a vpn originating from radio1 2. We "notice" low signal levels on radio1, toggle off the vpn, remove the IPs from radio1 (if needed) and switch to radio2 as our active radio 3. Set up appropriate IPs on radio2 and toggle the vpn tunnel on That sequence is not even going to take 1/2 second if you already have the radio connection on radio2. It would be unlikely to even drop a ping and more than likely, even a voip call would only "hiccup" instead of dropping. > I haven't done anything with any of these, so maybe I'm trying to solve a > problem that doesn't exist in your system. Not sure what you are trying to solve. I don't bother with the multiple tunnels, although it is certainly a possibility. Depending on the depth of the tests you run in your script, it could make the script(s) more or less complex, as you let OSPF worry about link viability. -- * Butch Evans * Professional Network Consultation* * http://www.butchevans.com/* Network Engineering * * http://www.wispa.org/ * Wired or Wireless Networks * * http://blog.butchevans.com/ * ImageStream, Mikrotik and MORE! * WISPA Wants You!

You can get 6mbit mobile broadband sometimes as a "perk" for getting a permanent connection in your apartment/house.

Re: [WISPA] Ideas on Police Department Wireless Link from Station to Cruiser
So in your described system, does it just use a single VPN link or multiple? I was thinking of your system before this thread came up and I was thinking of each connection having its own VPN back and using OSPF to handle link failures back home with each router having a loopback address everyone talks to. I haven't done anything with any of these, so maybe I'm trying to solve a problem that doesn't exist in your system. I'm looking to attempt to setup something similar, perhaps just as a tech demo, but maybe actually use it for something. Prefer the wireless links, but have a 3G card as backup. - Mike Hammett Intelligent Computing Solutions http://www.ics-il.com -- From: "Butch Evans" Sent: Saturday, October 17, 2009 11:56 AM To: "WISPA General List" Subject: Re: [WISPA] Ideas on Police Department Wireless Link from Station to Cruiser > On Sat, 2009-10-17 at 11:05 -0400, Robert West wrote: >> I got a call Friday afternoon from the police chief of a small little >> spot >> in the road asking about the possibility of connecting his cruisers to >> the >> station network via a wireless link. > > I have done this several times.

Re: [WISPA] New install driving me crazy....
Yabut, a dish "concentrates the forward radiation." So does a panel, a slot antenna, and many others. I just wondered why you thought a Yagi solved your problem. A 2.4G yagi has large diameter elements compared to wavelength, not like the old VHF Yagi's, but are prone to icing in the winter up north. What magic did you find in the Yagi? Just curious.

Re: [WISPA] Gotta Have
I gotta agree. One other nice thing with the EZRJ45 system is because the wires stick out the end of the plug as far as you want. You can verify the order, or pull them out and push them back in. THEN, you can grab the excess and pull until the jacket is as far up the plug as possible, THEN crimp. I can't tell you how many crimps I've come across where the technician didn't get the jacket crimped and a mm of strands shows before the plug. They also work with either stranded or solid wire so you don't have to have both or KNOW the difference between pointed or spade crimp points. I put the inventor of this crimp system in the same league as the geek who came up with sticky notes. Mike At 07:27 PM 10/18/2009, you wrote: >I don't care how much they cost.

I agree. At 50 cents, the aggravation saved is worth it. Anything to lessen the B.S. of life has value, in my opinion.

Re: [WISPA] Gotta Have
But you're missing the point. Yeah, Its definately not worth it, for those that can use the standard CAT5s effectively. But your math assumes that they can, and not considering the other costs. The ROI is NOT on the time saved comparing successful installs, comparing both types. The ROI is on time saved comparing costs of failed connector installs. What does it cost you if you crimp an end, and get a flaky crimp, and the link not work? How long does it take to figure out which side of the cable had the bad crimp? A 25 cent RJ-45 becomes 50 cents, if you ahve to cut one off and replace it. I can give an example of recently where I had to send a guy back into the city (half day's labor) to fix a packet loss problem caused by defective CAT5 plug terminations. But most of the lost time was in the office troubleshooting the defective packloss link trying to find what was wrong. I can sympathise with eye sight degrating, in my older age :-( . The error rate of successful CAT5 terminations go up, if eye sight is going down. The question to ask is are the installers having to high a failure rate for their first crimpts? If they are, then it may be a good investment. As well, I look at my time as worth $100/hr, and I'd gladly spend the extra $100 for connectors if it meant I was more likely to have sucessful crimpts the first time. I compare... Risking paying 25 cent extra verus risk spending extra $100 in time figuring out where I made the Crimp mistake. For the record, I do not use EZ-Rj45 plugs. But I understand the value of Using the best RJ-45Plugs, and the ROI is there. I personally like to use the the RJ45 Plugs sold by Shireen. Ever since we started using them, terminations have been so much easier and successful. I like the Shireen plugs because they have just the right wire hole diameters for the wire to slide in easy, and I can be certain that they'll slide into the right slots as I tried to align them to. (Its becoming harder for me to tell the wire color once its inside the Jack, due to eyes). And I can be certain they'll crimp securely. I also got tired of the two peice CAT5 jacks, because I always kept loosing the second peices, and ended up having to throw away 20% of them that would be incomplete set.

Re: [WISPA] Ideas on Police Department Wireless Link from
I have a large mobile police department deployment (100 current units and 85 more to come). We started with waverider mobile units in the cars but had to make a change because of all te problems withthe lms8000 radios. We ultimately went with alvarion radios. The cars have the ability to move between any of 4 towers and continue to move traffic. We have a custom website that we designed for all of their information and thy use thinkstream for background checks. We also designed a system that integrates their car camera system with a pc system. It works well and is priced good. If you have quetions I would be glad to help.

Re: [WISPA] Ideas on Police Department Wireless Link from Stationto Cruiser
I'm with you on that. I take most any opportunity to do a trade when we can both benefit from it. I want to use the water tower and they want a wireless link. In the long run, the use of the tower will surpass the value of that link. Their short term savings is my long term gain. -Original Message- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Marlon K.

That's a tricky one though. I know that in the past Steve Stroh had told us that all of an "educational TV band" 2.5 or something like that, was broadcasting the same show, at the same time.

Otard is just for property under the control of the subscriber, such as when selling residential service to a residential house. I sell primarilly to commerical property locations, such as Condos and Multi-tenant buildings, where the roofs and risers are not covered under Otard.

Re: [WISPA] Broadband Internet Access Deemed a Legal Right
Brad, First, I was being Facetious , I thought that would have been obvious. Second, Forgive the "generalized steriotypic" comment, as I did not mean to bundle all property managers/ owner into the same class. Many property Owners do "get it", and we embrace their allegience and we work with them effectively. When I say negative things about PRoperty owners/managers, I am only referring to the percentage of clueless property mamangers that just dont get it, and that have shown to be both destructuve to themselves, their tenants, and our company's progress, because they cant open their mind to new ways of thinking. Third, I have been in this business for 10 years now, and it took a while, but I've gotten to the point, that I pretty much have it down to a system how to work with the local property managers /owners as effectively as possible. BUT it was a long hard road to get here. It wasn't so easy the first few years. Admittedly, that actually works to my advantage now because we have LOTS of good relationships with PRoperty owners, that will be very difficult for new entrants to try and replicate equally. Fourth, My strategy has always been to look from the eyes of the property owner, understand their position, and find ways to allie property owners and manager, not fight them. In otherwords, how to make them your friend. There are many ways to acommplish the goal, but again, it was NOT a fast process to change the mind set of property owners in teh early years. It took persistance, and a 5 year history of proof to lay in front of them, to compare how property managers benefited or lost dependant on whether they had embraced our wireless broadband partnerships or not. Fifth, My frustration had always stemmed from the fact that 50% of our revenue to date went to Property owner, and they generally dont do jack squat other than delay the time it takes me to install subscribers. They do control valuable roof assets, which is why they sometimes get paid by me. It makes me laugh, when I hear consumers screaming for 30-50mbps for $25 /month broadband service, when I am often forced to pay Property owners/managers way more than that. I dont really have a propblem with what Proiperty owners charge, as long as its a fair competitive market, and I can charge my end users adequate fees to recoupe my costs that I pay property managers. BUT in talking National Broadband Plan, where there is a goal to lower customer's costs and raise their speed, One of the most effective things the FCC/Feds can do is lower the cost ISP's ahve to gain access to tower assets. Sixth- It is important to understand that all markets are nto the same, DC Metro is a very ruthless market when it comes to gaining roof access. In rural America the problem may be special access costs (RBOC?), but in Metro areas, we tade that problem for property owners that all want their peice of the action. I hear stories of many WISPs that barter most of their tower colocation, with very little cost for that. Or I hear stories where people can erect their own towers for a few thousant dollars. Or bought the land to build their tower for a few thousand. These things just aren;t that common here in DC. We live in a world of $17,000 Special exception permit applications. We live in the world of maximum broadband provider competitions, where roof managers try to give roof rights go to the highest bidder, and never really want to give it, because of the possibilty for a future hiugher bidder. And everyone wants Comast and Fios in the building, because the Public is most aware of these companies. Often these companies will refuse to come, if a third party ISP has been given rights to the building with signfiicant market share, abd Property owners are hesitent to select a small provider in fear they will retrict what the consumer may want more. But there are hundreds of scenarios, and they give the property owner the upper hand in negotiation. It takes a lot of creativity to get around the barriers.. Seventh, In the early year 1 out of 9 closed sales were prevented due to property management easement issues. Today, 9 out of 10 close sales, actually get installed, because we've learned how to better work with property owners, and target the locatiosn where we are successful. But its still a problem. And until a Wireless provider will have the same rights for rooftops, that an ILEC utility has for the ground, we will never be able to compete on equal ground, at the price points that The FEds and Public are asking and dreaming for. This is a big problem for us in public policy. ILECs can get 100% coverage, third party ISPs and WISPs dont have the legal rights to gain access to the resources to reach 100% of consumer. And the county and states dont have the power to give access to it either because they dont own most of the land that right-of-ways or Easements are needed. But its why I have a big
Re: [WISPA] Ideas on Police Department Wireless Link from Station toCruiser
We've worked with Butch to design a mobile MT system. It'll roam from tower to tower, even use the open linksys, netgear, etc. systems. Handles all of the IP address issues on the fly. Short outages only when moving from one tower to the next. It's not working perfectly for us yet, but we just did the real world deployment on the first two units.

Re: [WISPA] New install driving me crazy....
Speaking of longer links. I see people run the same size antennas on all of their installs far too often. I've seen 19dB panels on links that can't be less than 10 to 12 miles. I see 24dB grids on 1 mile links. Here is my rule of thumb. It'll have to change based on YOUR hardware etc. I'm always shooting for that -65 to -75 signal level, at BOTH ends of the link. up to 5 miles, 15dB up to 8 miles, 19dB over 8 miles, 24dB grid. On some of our 5 gig I have gone as high as a 3' dish for a customer on a ptmp system. He's around 15 miles from the tower and gets a steady 3/2 megs. The max that his Alvarion VL unit will allow.

Re: [WISPA] New install driving me crazy....
I don't Steve. But think of it like an echo. You get that first, clear signal coming in, laser straight. Then at some point shortly after that you start getting the reflections. If there are too many of them, and/or they are at the wrong time the radio will get confused. G SHOULD handle this better than B. It's made to use multipath's echoes to reassemble a complete message. Sometimes it works that way, sometimes it doesn't. I'd have to say, for me, g is usually better with multipath than b though. B handles interference better. At least that's what I'm seeing. I have a tower that was giving 1 meg down 2 to 3 up, almost all customers saw that or worse. Swapped back to b mode only and it's now a consistent 4 megs both ways. Another thing to try is to turn down the power. Probably on both ends. If you are at -69 see if you can drop your ap by 5 then 5 more db. Make sure to drop the cpe by the same amount. What you are trying to do is move the echo down so far that it can't be "heard". I've also had installs that are happiest about 2' above the ground! Here's a fun one for you. I've got one customer that shoots near a grain elevator. Most of the year he works fine, but near harvest, every year, his performance goes out the window. It seems that the wheat in the elevator is moved out and the empty elevator is worse than the full one. Out here we have VERY long links. I have one at 18 miles. PTMP. Yet there are also customers within 1 mile. 10 to 15 mile links are common place. Multipath is a real head ache as the ground conditions change. Customer's service will be perfect, until it snows. Or until they harvest a field, or the ground dries out, or it rains etc. Fortunately MOST of the time this isn't an issue. But when it does hit ya, it can be very hard to figure out. One other thing you might want to try with your customer, turn the radio to the wrong polarity. You are very close to the tower so you should still have enough signal. I've not had to do this very often, but it's a little trick that has worked before. I've also pointed them 180* the wrong way and had that work very well, especially with a grid. Let us know if anything helps. marlon - Original Message - From: "Steve Barnes" To: "WISPA General List" Sent: Friday, October 16, 2009 7:07 AM Subject: Re: [WISPA] New install driving me crazy > Marlon, DO you have or know of a good white paper on Multipath issues?

[WISPA] Gotta Have
I have learned a lot from this list. I think there is some real talent lurking here. We all have discovered certain things which just make life as a WISP easier. I think it would be beneficial to list participants in general if there was a thread which contained a description and use of something you find invaluable -- hardware, software etc ... you would like to share with the group. I'll start: what: EZRJ-45 connector system where: www.ezrj45.com why: As my eyes get older, and especially in low light situations, I find it very difficult to get all those individual conductors on a CAT5 run in the right order while crimping an end. This is a quite ingenious system. The plugs have holes all the way through. You can verify the color code easily BEFORE crimping and cutting the tags. It takes a special crimp tool which has a pair of blades that cut the tags as it crimps the connector in place. Maybe not a time saver in my case, but definitely a GRIEF saver. I've not miswired an Ethernet plug since I started using this system. Mike WISPA Wants You!
