Time Reports on Muni-Fi
(via Wi-Fi Networking News
) offers a decent run down of what's happening in the world of municipal Wi-Fi, replete with mentions of Earthlink, questions about financial viability, and the expected incumbent dig. "Wi-fi as a public service has serious issues like network congestion and security,"
says Eric Rabe, Verizon's senior vice president for media relations. "Do you really want your government handling your e-mail?"
For whatever reason the piece focuses strictly on Wi-Fi, and ignores the growing number of city owned or operated fiber optic deployments
What growing number of city-owned fiber optic deployments ?
The link provided only discusses Utopia in Utah. What other municipal fiber optic deployments are taking place? Any links?

Re: "Govt Handling Email"
said by blueeyesm:And Joe Network Admin can't?
What hw is referring to is the ability for the gov't to look at your email w/o a warrant.
Use the OS tool for the job.
Some salient technical points missed.... While the article is OK it really says nothing new, and even is incorrect in a few areas.
1) "City workers can use low-cost VOIP (voice-over-Internet protocol)"
Softphones dont authenticate via radius so the use of voip over these networks is not a reality at this point. (unless you mac pasthrough the phones and open up holes for mac spoofing and the like)
2)"and police and firefighters have a high-speed bandwidth for on-the-go access to data like criminal records and building plans or live shots from security cameras."
Not a 1 meg aggregate at excellent signal strength and not on the go, as the handoff issues with wi-fi has not been solved by tropos and the other vendors.
3)"Philadelphia created a government-supported nonprofit to oversee EarthLink's 135-sq.-mi. system, which should be ready next October"
Which October 07, 08 09 or 10....??? Wasn't this supposed to be completed in 05?
4)"waiting for WiMAX, a technology similar to wi-fi but faster and longer range, with fewer interference issues,"
Unlicensed 5.8ghz (wimax operates in 5.8ghz)is getting just as crowded as 2.4. Especially as people start deploying more wi-max and ptp 5.8 links. Case in point, I set up a 4 km (short) link from Miami to Miami Beach over the open bay. There is so much interference that we had to switch to 5.3 gear which has lower bandwidth and lower max power because the entire 5.8 spectrum was being used by other carriers. And there is no city 5.8 up at this point. Also technically, 2.4 has a farther range than 5.8 ghz due to high Free Space Loss at higher frequencies.
5)"Users aren't always comfortable knowing a government-run operation can track their searches for advertising or limit their access to websites."
Did they miss the whole at&t, google, msn privacy debacle last year?
Overall I find the article fair and basically accurate but it offers no new insight.
Muni Fiber has merit, especially where incumbents are too lazy or worried about ROI to make moves. However muni wi-fi is a like investing in the city's future by buying everyone a commodore 64, because its cheap enough to do. Wi-fi, as deployed by the muni, is not going to work and will quickly be bypassed by HSDPA and EVDO before many of these muni networks get completed. Especially as the cellular LICENSED services begin to lower prices.
BTW - My company just finsihed deplying a wi-fi network for a 500 unit building. We used 20 high power carrier grade access points and high gain antenna to provide the necessary coverage (got lucky it was a relatively easy install for coverage), it could use more for perfect coverage. Muni's use 25-35 access points (same power, worse antenna) per square mile,
Q: How can they cover there proposed area with 70% -90% indoor coverage (all rfp's I have read have this as a requirement) we 35 access points with low gain omni antennas
A: They can't! The laws of physics makes it infeasible.
Did I beat this dead horse enough??
Re: Some salient technical points missed.... Obviously 802.11b can do better than 1meg symmetrical. The issue is the mesh lowers throughput as hops increase. So 1 meg aggregate is about right as per Tropos, not me. My point is that if other users are on that node and download or Skyping or BT than there overall throughput could be lowered significantly. Why put public safety on a "best effort" network. This is what 4.9 was set aside for. Secondly the handoffs are not smooth as you may think. Even without authentication the Miami Beach study showed that links would drop and not re associate for speeds over 20mph, again not my imagination, the city's study.
For links as to when philly should have their network up read these (i found in 1 min)

Again not my estimation, but theirs.
Can muni wi-fi be done, SURE! can it be done the way many are attempting, NO!
Show me one that works well and I will STFU but until I see a viable installation that truly competes with DSL and Cable than I will keep calling people on the pipe dreams.
Oh yeah the city of Miami Beach network was supposed to be completed by summers end....looks like next summer maybe at the pace of their deployment.
BTW - My model is long changed from what it was before my muni stated encroaching and will continue to evolve as different market forces come into play, something a muni cannot easily do.
I am for muni broadband, its actually part of the reason I got i the game, becuase the incumbents suck, but I cannot support something (muni wi-fi) that I know is not a good long term solution.
Muni fiber....now there is an idea
