periol wonders: "I'm the sysadmin for a firm in mid-town Manhattan that is moving to a larger workspace six months from now. The new space is on one floor (100+ users to begin, 200 capacity) and is completely stripped. We've been playing around with the idea of completely wireless office, with no ethernet except to the access points (probably running over VPN for security). Email and files are all accessed locally over the network, and there is a web application hosted off site. Does anyone have experience with this kind of setup? My calculations are that we would need one access point per 15 computers, but I don't know what kind of issues we'll run into along the way. Will we run into unexpected periods of network downtime with a wireless-only setup like this?"
