Hi Pulkit,
The autonomous 1130AG series access point supports these operating wireless modes:
? Root access point?Connected to a wired LAN and supports wireless clients.
? Repeater access point?Not connected to a wired LAN, associates to a root access point, and supports wireless clients
? Workgroup bridge?Not connected to a wired LAN, associates to a root access point or bridge, and supports wired network devices.
As this unit was not designed to be use outdoors, having a clean RF line of sight is really difficult. To be honest I do not think this unit was designed to connect two remote buildings even if the units are indoors. I would look for APs with detachable antennas like the 1242AG or the 1200 modular series so you can use external antennas and bridging roles.
Hope it helps,
Roger Carpio.
