  • Method and apparatus for beam steering in a wireless communications systems
    Publication number: 20050148370
    Abstract: A med and apparatus is provided that allows M transceivers to transmit/receive using M2N distinct beams using passive beam steering. This provides for the use of arbitrary narrow beams with a number of transceivers that is a fraction of the number of beams but ensures 360° coverage. In other words it permits significant improvements in the link budget with a minimal rise in the cost of the BS. The apparatus includes M distribution switches applied 2N passive beam forming networks each coupled to M antennas. The method and apparatus ate compatible with TDMA in the downlink and in the uplink.
