I have a couple of Cisco 1242AG access points placed on either ends of a long corridor. The Cisco patch antennas are mounted on the side wall of the corridor. All the doors to the bedrooms are firedoors and majority of the walls are plasterboard. I would like to move them to achieve better coverage on the floor. Their are firedoors which divide up the corridor and these are always open. I am thinking of placing the access point above these doors and a patch antenna on either side of the wall above the fire door. Will this work or do the antennas have to be next to each other pointing in the same direction?
