The network I am attempting to create will consist of a rather large layout of access points and repeaters. Since the anticipated area of coverage in terms of square feet will be huge, I am considering modifying the antennas. Each unit will recieve a parabolic or sector based antenna, meaning the antenna has only about 90 to 120 degrees of horizontal coverage. Since this is only half the area, a second unit with similar equipment facing the other way will be needed. Is it possible for them to be hooked up together and act as though they were one? Can they be setup in some way that they both act as repeaters, but wire them together so they talk to eachother as well? Or should I set one up as a reciever and transmitter, wire it to the other and make that one work as only an access point? Are there any other possibilities, such as setting them both to act as access points, and using a WET54 to bridge out to the rest of the network?
