Advice on Aironets for this scenario

[visionthing]

What I'm looking at is 3 buildings total.
1 building is the main building
2nd building is across an alley with 1 PC(for now, but may grow)
3rd building is about 200 ft away, also with 1 PC (again for now, but may grow)

All buildings have line of sight between them.

Looking for the best Aironet solution for the above. The 2nd and 3rd building PC's will need access to the main building. Will 3 bridges work for this scenario, or will I need an
AP. I'm not needing wireless client connectivity in the main building (again for now, but that may change).

Thanks

I would use 3 of Cisco's 1242AG radios. The central site would configure as root bridge with wireless clients. The two perimeter sites would be non-root with wireless clients. The central AP would connect to the wired network via Ethernet, broadcast a b/g coverage cloud, and use the a radio for bridging. Perimeter APs would connect as bridge clients via the a radio for backhaul, and connect to hub/switch via Ethernet to provide wired access, and (bonus) provide wireless access via the b/g radio.


Why is there never a phone in any of the phone closets?

You say you have line-of-sight (LOS). Just wanted to point out that visual line of site and RF line of site ARE NOT the same. I would suggest a proper site survey before specifying equipment. You never know what kinds of interference might be in outside the walls of your buildings. Good Luck.

I went with 1310's and set the main site up as "root" and other 2 as "non-root". The configuration went fine and I've tested them using 3 seperate hubs connected to the 3 seperate aironets. I had wanted to do a site survey, but couldn't convince them because I guess they wanted to save money. Also, I'm not doing the physical installation as the radio's are going outside, so that part is not on me.
One last question though. I've set them up with WEP, though they wanted WPA. I'm pretty sure that for WPA to be applied with the aironets that there must be a RADIUS server in use. I saw at the WPA setting in the GUI, that it asked for the RADIUS servers address, etc. Do I have this right?
