  • Patent number: 7969910
    Abstract: A method for inserting an access point unit into a wireless telecommunications network, comprising: performing a self installation process in the access point unit, wherein during said self installation process, the access point unit automatically detects physical and RF layer parameters of access points around it, and selects its own physical and RF layer parameters according thereto, and/or performing a self-interconnection process in the access point unit wherein the access point unit contacts at least one feeder; and said feeder determines whether or not to permit connection of said access point unit to it.

  • Patent number: 7970355
    Abstract: The present invention describes a method of closed loop MIMO communication utilizing implicit or explicit channel state information (CSI) at the transmitter and the receiver. The transmitter performs linear pre-processing (for example, QR decomposition or bi-diagonal decomposition or Jacobi rotations, and/or sporadic SVDs) on a channel matrix, and the receiver mitigates the mutual interference between the streams by performing MMSE processing on the received signals. The MMSE matrix is computed with respect to the processed channel that may estimated by the receiver through preprocessed pilot signals. The transmitters preprocessing is of much lesser cost and complexity than full SVD.

  • Patent number: 7574179
    Abstract: A mobile broadband wireless system including at least two pairs of nodes arranged in a cluster, each pair coupled to form a link for wireless communication. Each node includes an RF transceiver with associated modem, an antenna array arrangement coupled to the modem and arranged for multiple concurrent transmissions, where each antenna has a beam pattern selected to improve quality of transmission, and a controller for controlling the transceiver, modem and antenna array arrangement for providing point to point communication. The controller allocates MIMO streams and modulation to different antennas in the antenna array arrangement, and implements at least one interference mitigation mechanism to minimize interference within the cluster during multiple concurrent transmissions. A method of wireless communication is also provided.
