Hi, can i get a 3x3 mimo board, such as http://routerboard.com/RB953GS-5HnT , or http://routerboard.com/RB921UAGS-5SHPacT-NM

If i set the maximum data rate to 54G, the radio will operate as three synchonized chains?

In other words, is there a way in wich i can plug three directional antennas to a 3x3 radio, so as to have wider coverage of an area (off course at the cost of troughpout?)

I'm in need to share a 2mbps connection to a large area, and i hoped to use one radio only, with one ssid, and no roaming magic.

Yes, you can do this. You can put three antennas on a RB953GS oriented in different directions.

But I am not sure if there will not be used only one chain in g or in b mode...

I think it's a bad idea to use mimo with antennas pointing in different directions. For a good mimo you should have a similar signal strength on all chains.

He's not talking about using the advantages of MIMO throughput - but using the separate chains as if they were all seperate AP's (in essence) by limiting to 802.11b/g

I don't know the answer though unfortunately.

I doubt that he will have the good result even for only 802.11b/g. My suggestion is to have a dedicated radio per direction/sektor.
