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.

These modules are so small that Sony engineers gave its volumes in ml which is reasonable if you think of the size of unit. There are two different models. The first and smallest chip ? BTF-ZJ401 has just a 1.5 ml volume (25x20x3mm, 3.5g). That is roughly 1/25th the size of chips on the market today. The second, BTF-ZJ411 is a bit bigger at 2.5ml (40x22.5x2.8mm, 4g). The main difference between two modules is the ability of BTF-ZJ411 to extract stereo sound from the radio signal.

Utah's CTO explain 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.
