Abstract: Disclosed is a system utilizing a multi-beam antenna that switches the beams to a CDMA demodulation receiver in such a way that the best beams are selected. The transmit path takes the traffic channel outputs from the CDMA modulators and maps each traffic channel to the subset of beams that have the best path to the mobile in the forward link.

Abstract: An omni directional coverage multibeam antenna composed of facets, or antenna modules, that make up a regular polygon of n sides inscribed in a circle of radius r which defines an adjustable composite conical surface. The disclosed antenna modules are independent antenna arrays creating an independent beam. One advantage of such a system is that the radiated wave front associated with such antenna modules is always substantially broadside to the array resulting in limited scan loss effects. Furthermore, the independence of the disclosed antenna modules is important as it allows each module's beam to be either electrically or mechanically steered to affect elevation or azimuthal beam control. Additionally, by employing trapezoidal shaped antenna modules, a minimum radome diameter is achieved that covers this antenna system.

Abstract: System and apparatus for actively managing calls in a wireless cellular network. A host receives input data from a plurality of cells regarding the status of calls in that cell. Input data may include call variables such as carrier signal strength over interference (C/I), forward and reverse link power, beam and channel assignments, handoff status, and triangulation data regarding location/movement of active calls. The host processes the input data with reference to known cell neighborhoods, and creates output data for each cell that includes information on other active calls in the neighborhood. The output data then updates the cell with information regarding active calls in the cell's vicinity. The cell may then make adjustments to call variables taking into account local interference conditions.
