Patent ID: 8605708

Claim:
A wireless communication system comprising: a plurality of wireless terminals that configure an equally distributed network having no base station, wherein each of the wireless terminals includes: a space division multiplexing (SDM) transmitting unit that includes an array antenna including a plurality of antennas and generates a plurality of directional radio signals to be transmitted to other terminals within the network, each of the directional radio signals being obtained by superimposing a plurality of radio signals at the antennas, each of the radio signals at the antennas being composed of modulated data for each of the other terminals; a single-system receiving unit; and a time division multiple access (TDMA) control unit that controls a transmission operation of the SDM transmitting unit and a reception operation of the receiving unit in a time division manner, and using a TDMA scheme, the wireless terminals are controlled in such a manner that any one of the wireless terminals acquires a transmission right for a predetermined time period to simultaneously transmit the generated directional radio signals from the SDM transmitting unit, while during the predetermined time period, the receiving units of the other wireless terminals having no transmission right simultaneously receive their corresponding directional radio signals which are different from each other.
