Here is our current setup 4 locations all within 3/4 of a mile. Main location has about 25 workstations and the other 3 locations have no more than 10 users each. Network traffic is not heavy, mainly file sharing and email. We currently have a 56k frame realy linking the 4 locations and are considering going to a wireless link. We are looking at the 3Com Wirless Lan Building to Building bridge with 3 sector panel antennas for the branch offices and and an omnidirectional antenna for the main site. Just looking for any feedback from anyone that has tried a similar set up or any advice you could offer. This is my first attempt at wireless.
