Claim One:
1. A method comprising: (a) initiating a multiple input and multiple output (MIMO) training procedure in a wireless network; (b) transmitting training frames using all TX sectors during TX sector sweeping and in response obtaining a set of selected TX sectors for each TX antenna, wherein each of the TX sectors corresponds to a specific TX antenna beam; (c) transmitting training frames using omni-direction antenna pattern during RX sector sweeping and in response obtaining a set of selected RX sectors for each RX antenna, wherein each of the RX sectors corresponds to a specific RX antenna beam; (d) starting MIMO beam combination training based on pairings of the selected TX and RX sectors, wherein each of the MIMO beam combinations includes one of the selected TX sectors and one of the selected RX sectors; and (e) obtaining multiple best MIMO beam combinations for multiple MIMO spatial streams based on the results of the MIMO beam combination training.
