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!

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.

Maybe hard..but not impossible. Is my solution better? Hard to say. I'd be hard pressed to say outright that the mesh solution is better, though. FWIW, my solution would work fine if the infrastructure WERE a mesh, but it does not require it. I'd suggest reading through the blog post I made that details some of the obstacles that this type of network has to overcome. I have built this solution with MT CPE (in the cars), but it can be done with nearly ANY CPE that can be made "smart" with a script. I have been playing with ImageStream devices as the router connected via ethernet to multiple radios and am nearly able to do the same thing with ImageStream (which means virtually ANY Linux device can do it). The brains in my solution resides in the CPE, and not the network. > Also, I doubt that Homeland Security is paying for anything here or they > wouldn't be hitting up Walmart for free laptops :-D Probably correct. The reason they are not likely to get homeland security dollars is more because they don't know and didn't ask.

My method offers some significant advantages over a simple meshed network, however. As I said, the brains are in the CPE. What that means in the real world, is that I can allow the CPE to connect to ANY network that I know about and can configure interfaces for. I built one network that utilized 3 ISPs with access methods that varied from DHCP, PPPoE and Static IPs (different IP, depending on the tower we connected to). That is something that a mesh cannot compete with, since the mesh would be owned by a single entity (at least in most cases). > With that said...

An if it sounded like I was knocking the Moto option, it was not intended that way. The fact is, that I know (from experience) that we are not nearly as limited as your post seemed to suggest. With smart CPE devices, you'd be surprised what can be done. In some cases, we can do way more with my methods than any other solution is capable of. > Heck I'm really advocating air cards > here...

It really depends on what they need. If it is simple access (even with a vpn) to a network that can handle the high latency and low speed of the cellular network, then an air card is almost certainly the best option. -- * 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!

Re: [WISPA] Ideas on Police Department Wireless Link from Station to Cruiser
Butch, Cellular isn't that expensive when you're talking a few cars... if you're talking 30 patrol cars... I agree it's expensive. Heck, if the city has a ton of cell phones already they might be able to get the service free. I've heard of cities getting aircard equipment to do network monitoring type work at night when the network was offloaded for pennies a month. I agree that Mesh is way beyond what most departments need. Many police departments have two officers in their cars... so the second officer needs to be able to work on the laptop on the way to a call etc. Probably not a requirement here since it's a small town... but for instance one city I am working with now wants to be able to watch streaming video from security cameras while driving up to 75MPH... that's hard to do without a Mesh IMO. Also, I doubt that Homeland Security is paying for anything here or they wouldn't be hitting up Walmart for free laptops :-D For your last part... you didn't explain what you did for your network. What equipment was used, how it was configured, etc. I would suspect you ended up working around the 802.11 protocol to handle the roaming hand-offs better. It might not be a true mesh (meaning you have actual nodes meshing), but something similar must be done (more AP's than point to multipoint service to account for worse link budgets from omni's and typically NLOS shots). Generally it's also best to have the AP's below the trees... also kinda lends itself to a mesh. With that said...

It's all about explaining benefits and pitfalls. Once the network needs are known (which they are not at this point), THEN a solution is devised. For what it's worth, the second time I did this type of network, we watched a LIVE streaming video from one cop car as it drove all over town without more than a 1 second hiccup (which happened 2 times).

Re: [WISPA] Ideas on Police Department Wireless Link from Station to Cruiser
In my area, South Central Ohio, Verizon, Sprint, ATT all have issues. The latency is all over the place and the ul/dl speeds are inconsistent over the span of even 5 minutes. I have a customer who we were trying to hook up to her office in town from her home in BFE via VPN but it was miserable. Both Sprint and Verizon gave her fits. She was supposed to have a 2mb download and 1mb upload and it was running between 512 and 768 most of the time and it was pinging in the 200 range. Nasty, nasty, nasty. But of course near a better populated place, it would fly.

You are thinking that an officer of the law is gonna be using the network while driving at 30MPH+?

It's all about explaining benefits and pitfalls. Once the network needs are known (which they are not at this point), THEN a solution is devised. For what it's worth, the second time I did this type of network, we watched a LIVE streaming video from one cop car as it drove all over town without more than a 1 second hiccup (which happened 2 times). Additionally, he was talking to us via an 802.11g wireless voip phone and NEVER lost the call. This was using a mixture of 2.4GHz 802.11b, 802.11g and 900MHz (Mikrotik 802.11a I think), if you're interested. Not too bad for not having purchased, or even considered Moto. I think to dismiss a technology outright before understanding what good engineering can do is pretty short sighted. -- * 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!

Re: [WISPA] Ideas on Police Department Wireless Link from Station to Cruiser
So the cops could be watching You Porn while driving at 144mph? That's a very good selling point that could sway some departments. I personally like the Cellular option. The infrastructure is already in place for the most part, just tie into office system with a VPN and a firewall and they should be good. The bonus would be having an internal card in the machine instead of the USB deal. It all comes down to money for the monthly fee, I bet. The biggest plus on that I see is if they transport a prisoner, which they have to do since they have no jail (Thank god!) and they have to go 15 miles away to the sheriff's department. So, this would be my pick after all if the politics turn out to be good, an internal card in the laptop would make that an easier sell.

Re: [WISPA] Ideas on Police Department Wireless Link from Station to Cruiser
What about the air card? I would assume that the aircard service fee isn't being paid by the state? That would be the ideal situation but this town Very political. I know there would be a fight over who had access to it and when and anything else they could fight over. But I;; write that down as an option to go over with them. One never knows. Ruggedized dells.. A far cry from this nasty Acer laptops from Wal-Mart. But they are worth the price they are paying for them, free. Thanks for the idea.

They have 13 of those ruggedized Dell laptops, mounted in all the cars. We looked at 2.4GHz and 900MHz. Even though the town is only 5sqmi, we decided to go with Verizon Aircards. Worked out well, because the laptops are tied directly into their CAD system, which is tied into the whole state. So now they could, theoretically, go anywhere in the state and be dispatched on a call, run plates/people through NCIC, etc. I believe that because of that, they actually got the state to pay for a lot of it. Sure, we don't make anything on the Verizon service, but we do on the backend by tying their CAD into the Internet. Just something to keep in mind, if you have any sort of 3G service in that area.

West Bend Wisconson St Louis MO Chicago IL Top Sail Beach NC All the way up and down I75 in Ohio Not one of these places has a solid AT&T 3G service. Neither using the PC Express Card nor the integrated Sierra modem. I have had what I consider bad service all around, which is why I said what I did. Not saying it will be bad, but I would avoid it. You have had the opposite experience, so you said what you said. Just voicing my experience and my opinion...

Re: [WISPA] Ideas on Police Department Wireless Link from Station to Cruiser
Josh, It kind of depends where you live, just like it does for any 3G service. Where I personally live, AT&T's 3G service is excellent. I switched from Verizon and have better coverage and better performance. I'm sure the reverse is true in other areas...but you really cannot legitimately make blanket statements like that when they need coverage in a specific relatively small area.

Re: [WISPA] Ideas on Police Department Wireless Link from Station to Cruiser
IMHO, the only way to do something like this where the office is mobile is with cellular service (although he will need to VPN back to the Police HQ) or to use a Mesh network designed for mobility (since 802.11G tends to fall apart past 30MPH or so). Unless this city want's to make a major investment in Mesh... I'd tell him to stick with the cellular air cards (Verizon, AT&T, whatever) and be done with it. Hacking together a solution is probably more effort than its worth, and there could be theoretical consequences if the network doesn't operate correctly. I'm still nowhere close to being able to offload this... but down the pipe I know of a city that is replacing their MOTOMESH Solo network with MOTOMESH Duo... so those nodes would probably be cheap... and it allows the cop cards to go up to 144MPH in the Mesh and still stay connected (its actually really cool technology developed for the US Military... but the most it can do is T1 speeds) Daniel White 3-dB Networks http://www.3dbnetworks.com >-Original Message- >From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On >Behalf Of Robert West >Sent: Saturday, October 17, 2009 9:05 AM >To: WISPA General List >Subject: [WISPA] Ideas on Police Department Wireless Link from Station >to Cruiser > >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.

Re: [WISPA] Ideas on Police Department Wireless Link from Station to Cruiser
We currently do this for a local PD. They have 13 of those ruggedized Dell laptops, mounted in all the cars. We looked at 2.4GHz and 900MHz. Even though the town is only 5sqmi, we decided to go with Verizon Aircards. Worked out well, because the laptops are tied directly into their CAD system, which is tied into the whole state. So now they could, theoretically, go anywhere in the state and be dispatched on a call, run plates/people through NCIC, etc. I believe that because of that, they actually got the state to pay for a lot of it. Sure, we don't make anything on the Verizon service, but we do on the backend by tying their CAD into the Internet. Just something to keep in mind, if you have any sort of 3G service in that area.

[WISPA] Ideas on Police Department Wireless Link from Station to Cruiser
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. (He is the "Police Chief" but I suspect he is also the entire police force) He said that the local Wal-Mart has agreed to donate to him a few of those little Acer 7" screen laptops, which are a big piece of crap from the number of repairs we've had to do on them... Anyhow, he wants to be able to be in the cruiser and connect to the network back at the station and use the websites from the Attorney General's office where he can run plates, drivers license info and also fill out his reports. Here's the setup.. This Burg is a bit less than 2 miles long and about one and a half miles wide. The town hall is equivalent to a 4 story building and they also have a water tower that looks to be 100 foot tall. The terrain is flat as can be and they have the normal scattering of trees. The Town Hall and water tower are the tallest structures by far aside from a large grain elevator right outside of town. Boy wants to connect to his network anywhere in town from his cop-mobile as well as when he is at home, also within the town. We've done plenty of private networks but it's all been in the 2.4 and 5ghz band. He was thinking he could just throw up a 2.4ghz link and be good but I told him to hold on, I didn't think he could broadcast the Attorney Generals network to every antenna in town, I had to do some research. So this, because of my utterly blatant laziness, is my research. J Has anyone been down this path? What can we do and not do? I have a meeting with the guy next Wednesday and want to have some idea of what we're up against on this one. (Hopefully he doesn't recognize me as the guy who took him to court over a ticket he wrote for a crooked license plate... I won that one by the way) Thanks for any help!
