Multiple WRTs acting as one?

    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?

    Under correction here, but a WRT54G/S/L, and maybe others, only use ONE antenna at a time, meaning that full power goes out/in one antenna at any time. Therefore, if you connect both (assuming you need 2 only) your sector-antennas to the same AP, facing different directions of course, you may have what you want already.

    If you need more APs, you can have all APs wired together through LAN ports, using the same SSID, but on different channels. This will allow clients to roam just about seamlessly among APs. If you want different subnets, well, I'll leave that to another forum member....

    Same subnet is fine. If I turn on both antennas on the access point, will the power be split between them? For example, if I turn the power up to 100mW, will each antenna push 100mW or will they just be 50 each?

    No, as I understand, diversity means that full power goes to one antenna at a time, and both antennas can not be "on" in the same microsecond (or nanosecond/picosecond). So when the received signal from a client is strongest on the left antenna, the AP will talk back to that client through the left antenna, at full power (100 mW in your example). When it talks to another client through the right antenna, full power will go that way.
