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.
