Anchordesk finds trouble in Wi-Fi compatibility: Daniel Miller hits every problem one can with trying to use a Wi-Fi card with enterprise and VPN systems. It's a cautionary tale, as it shows how what seems to be a simple proposition becomes out of control when you layer reasonable security through encrypted on top of it. I come out in the article for WPA, which would solve all his troubles, except, possibly the VPN tunneling on untrusted networks, but it should at least make LEAP no longer his network's standard.

Utah's CTO explains Wi-Fi total cost of ownership (TCO): For a concise and real-world, hard-won explanation of the total expenses involved in deploying Wi-Fi networks in a large organization, read Phil Windley's essay. His comment on VPNs is interesting, of course, as I predict (based on many more involved people's opinions than mine) that 802.1x/EAP plus a secured form of EAP will allow enterprises to abandon local VPN requirements by offering security as robust as a VPN without the expense and overhead. In fact 802.1x/EAP might be an excellent supplement or sidecar to encrypted VLANs, which already use something very much like it.

Airshare and Enjoy: Airshare.org is a site dedicated to educating people about the use of wireless networks. I like how the site is divided, and its focus on helpful how-to projects. They've posted Adam Engst and my 802.11g/AirPort Extreme article, and have discussion forums and other points of interest for anyone learning about or trying to teach others about wireless networking. You can also contribute content of interest to them to better spread the word.

InStat/MDR estimates 1,500-1,800 wireless ISPs: A new report from InStat/MDR using data from the Broadband Wireless Exchange suggests a robust mom-and-pop-sized wISP market. The high-tech market research firm estimates that there are 1,500 - 1,800 license-exempt WISPs in the US and worldwide end user revenues generated from infrastructure in the license-exempt WISP market are forecasted to be $265.2 million for 2002. The report costs $2,500.

Nashville Wi-Fi: Another regional story about Wi-Fi in the local market. The reporter repeats something mentioned in the New York Times article about Long Beach without mentioning the source or that in the original article it was a speculative based on reports that the article didn't mention: That's why Seattle, San Francisco, San Diego, San Jose and other tech-savvy cities have committed to creating ''hot zones'' in their downtowns. Although community wireless projects in at least some of these cities are bringing in wireless in larger areas, none of those four cities have municipally supported projects that I'm aware of.
