I have a customer (Hotel) that has multiple conference rooms throught it's buildings. These conference rooms are around and below guest suites. They would like a good strong wireless signal inside each of the guest suites but would like to keep the wireless signal out of the conference rooms all toghether. THey want the guest suite wireless to be free and open (no authentication) but do not want the conference rooms to have any access to the wireless. THe rooms are physically ajacent. Any ideas short of telling them they are nuts?
