Sure, Here is some basic info about the wireless stuff. Once you have a solid wireless link, everything else should work as if the workstations were local. I'll be happy to provide more detailed info (part #'s, etc.) if necessary.
Our school network is 100Mb switched (mostly) The wireless equipment involved is the Cisco Aironet stuff. There are many other manufacturers. There is a bridge on our school LAN with an omnidirectional antenna set up on top of one of our buildings. We then have multiple outlying buildings (including my house :-) set up with bridges and directional antennas pointing back to the omni. There is a requirement for "line of sight," but because this stuff is pretty low frequency, you can deal with some obstacles on short shots. With the correct high gain antennas and good line of sight, this equipment will work up to 20 miles!! Effectively, this puts me on the school LAN (at 11Mb/sec), so an LTSP terminal plugged in at my house works EXACTLY as if it were at school. Prices on the wireless equipment have dropped dramatically. Some of the things you want to think about. 1. These are wireless bridges, not hubs or "access points". Although, some access-points available today have bridging mode. 2. Power, our broadcast bridge is 100mW. Some of the outlying buildings have 40Mw bridges that are much less expensive. Depending on distances, you need to have adequate power. 3. Antenna gain. Antennas basically focus the power coming out of the bridge. Therefore a directional (dish, yagi) antenna that focuses the power in a concentrated direction will shoot farther than an omnidirectional antenna (whip) as a general rule. Gain is measured in dB. 4. line of sight. basic line of sight is important for reliable communications, although as I said, for short hops, you can usually deal with some obstacles.
