Claim Text:
1. A method for wireless communication comprising: generating with a first controller in a master wireless node a first allotment of sub-carriers selected from a predetermined frequency band for communication with a first slave wireless node, the first allotment of sub-carriers including at least two orthogonal sub-carriers; generating with the first controller in the master wireless node a second of allotment of sub-carriers selected from the predetermined frequency band for communication with a second slave wireless node, the second allotment of sub-carriers including at least two orthogonal sub-carriers that are different than the at least two orthogonal sub-carriers in the first allotment; transmitting with a first transceiver in the master wireless node a first message to the first slave wireless node using only the first allotment of sub-carriers and a second message to the second slave wireless node using only the second allotment of sub-carriers, the first message being different than the second message and the transmission of the first message and the second message occurring substantially simultaneously; generating with a second controller in the first slave wireless node a third message for transmission to the master wireless node; and transmitting with a second transceiver in the first slave wireless node a preamble to the master wireless node followed immediately by the third message using the first allotment of sub-carriers, the preamble including a first predetermined sequence of symbols, a repetition of the first predetermined sequence of symbols, and a second predetermined sequence of symbols having a low correlation to the first predetermined sequence of symbols.
