Re: [WISPA] Ideas on Police Department Wireless Link from Station toCruiser

2009-10-18 Thread Marlon K. Schafer
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.  I think Butch has a number of them in 
more controlled situations working nicely.

 the

 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)

Regardless of the technical side, I would urge you before spending
any money or time - contact the AG's office or whoever is the TAC for
NCIC in Ohio.  While OHLEG does have
an internet portal, when you go to the other data centers such as LEADS
or NCIC your transport options begin to disappear, as well as mixing the
pipe with internet.

I have seen this issue cause a couple of real issues before.

NLETS is the tool for checking information from other states.   It ties
all the state networks and the federal systems together.
http://www.nlets.org/

When an officer runs a tag, or DL, etc, it dips the state databases, and
also dips many other databases through NLETS.

Re: [WISPA] Ideas on Police Department Wireless Link from Station toCruiser

2009-10-17 Thread 3-dB Networks
Not for mobility it won't.  4.9GHz is great for point to point or point to
multipoint... but if you want mobility... your back to a 4.9GHz mesh to make
it work reliably.

There is an alvarion 900MHz system that alvarion claims will work from one
tower in a situation like this... but without having touched it I won't
recommend it :-D

It probably comes down to two things:

1) What are the throughput requirements
2) Is mobility required (mobility meaning driving around the city and
staying connected)

Either way... the most cost effective solution (especially if there is only
one or two cars on the force) is going to be utilizing some sort of 3G
service.  Mesh networks (and I should specify, Mesh networks designed with
high speed mobility in mind... some sort of proprietary protocol has to be
used for the switching) are going to provide the best coverage at high
speeds with the highest throughput... along with giving the city a network
it controls.

If mobility isn't required... you could do more of a hotspot type
solution... or a high gain omni on the car with some high gain omni's on the
towers... but there would be no guarantee of reliable service everywhere...

Robert... no matter what make sure before you do anything that the
expectations are clear, and that you have a contract written.  If the city
doesn't like the way the network performs, you could have a serious lawsuit
on your hands (since it is a public safety application).

And that's what my original thought was.  I'm big on the trade and I would
love to have full reign of the water tower in exchange for free labor. I
could use the thing for a redundant gateway since Time Warner runs right
past it and it's in a good spot for backhauling to some outlying grain

it work reliably.

There is an alvarion 900MHz system that alvarion claims will work from one
tower in a situation like this... but without having touched it I won't
recommend it :-D

It probably comes down to two things:

1) What are the throughput requirements
2) Is mobility required (mobility meaning driving around the city and
staying connected)

Either way... the most cost effective solution (especially if there is only
one or two cars on the force) is going to be utilizing some sort of 3G
service.  Mesh networks (and I should specify, Mesh networks designed with
high speed mobility in mind... some sort of proprietary protocol has to be
used for the switching) are going to provide the best coverage at high
speeds with the highest throughput... along with giving the city a network
it controls.

If mobility isn't required... you could do more of a hotspot type
solution... or a high gain omni on the car with some high gain omni's on the
towers... but there would be no guarantee of reliable service everywhere...

Robert... no matter what make sure before you do anything that the
expectations are clear, and that you have a contract written.  If the city
doesn't like the way the network performs, you could have a serious lawsuit
on your hands (since it is a public safety application).

I myself would look into 4.9 or other licensed spectrum.  Then you could
have gear on one tower and service the whole area...

 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, ATT, 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)

 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.  (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
