We've finally made the plunge into the 802.11 realm full tilt. We had avoided this technology due to cost and RF performance. Currently the three AP's are connected via proprietary pre-802.11 equipment. In these areas one can associate to the AP with an 802.11b compliant STAtion. WEP is not employed.
Users are responsible for protecting thier data over the wireless link.
Connectivity to Cambridge is via VPN over terrestrial cable based networks. An 802.11 gnet architecture draft has been crafted up for comments. Milestone Timeline and Current Report has been updated.
