I need to connect two apartment buildings which are roughly two blocks away from one another. The buildings are in LoS of each other. The plan: Wireless router in Building A, with a -12dB cantenna connected to the router. Then at Site B another Cantenna connected to a wireless bridge. The Question: Site B is an eight unit apartment building. Theoretically will i need to connect one or two more bridges to link all eight units to the main feed. Not all bridges will have cantennas only the one to recieve the extended signal. Any guidance would be very appreciated.
