The Town of Smithtown on Long Island is saving $5000 per month by converting to a combination wireless and VPN network for their intra and internet needs. We performed this installation partnered with NPA Computers of Holbrook, NY. A logical diagram of the connections is shown here.
The network that we created for them replaces a hub and spoke Frame Relay net that couldn't support their current need for internet access at each of the town offices, and the increased intranet bandwidth required by new applications and internal files. In downtown Smithtown, we created a wireless intranet by using 20 Megabit/sec 5.8 GHz Motorola Canopy Backhaul links between the Town's main data center and several other buildings. Somewhat ironically, we had to mount one of the Canopy units on an existing radio tower to get over the Verizon central office that stands in between two of the buildings. Each location has Business Class Optimum Online from Cablevision, which provides between 5 and 10 Megabits download capability and 1 meg upload. In the Town Campus, we also use the BCOOL links for a set of tunnels that backup the wireless, so that if a lightning strike takes out a link, the system fails over to the VPN tunnel, and reverts back to the higher capacity link when the link is fixed. We get about 5ms latency on the Canopy links, and 35-40 ms latency on the VPN links.

At Friday's LIMBA meeting Frank J. Russo spoke on how school taxes on Long Island are out of control, and are the largest component of the homeowner's property tax bill. He sees the problem as two-fold, total compensation of staff is too high, and voter turnout is very low. He introduced us to a relatively new organization, Long Islanders For Educational Reform LIFER. A (cheesy -editors note) website can be found at www.lischooltax.com I had expected a vitriolic screed ranting about how the educational system is broken and how we can save a ton of money by creating megadistricts. I was pleasantly suprised by the sensible and moderated tone of his comments. Mr. Russo's stump speech is laden with staticstics, none of which I could verify, but they sound reasonable.

Many thanks to Esme Vos of MuniWireless for pointing out that the responses to the San Franscisco citywide Wi-Fi cloud are posted on the web here. I am currently poring over them, and finding that they are a treasure trove of competitive information, and I am amazed that so many companies have submitted incredibly narrow proposals that omit crucial components of a network. It seems that many product companies have just thrown their set at the requirement and left the holes unfilled.
My favorite paragraph so far is this one from the Google response.
