A method and apparatus for processing multiple signals at a common frequency combined into a single radio frequency cable and subsequently recovering the signals without significant losses, distortion, or cross-talk. The method and apparatus includes processing multiple signals at a common frequency fed through a single radio frequency (RF) cable with or without one or more amplifiers and utilized for either forward or reverse link transmissions. The invention enables a single power amplifier to amplify multiple RF signals that occupy a common frequency channel and after amplification splitting these signals into amplified copies of the originals. The amplified signals may be sent to different antenna ports to illuminate different base station sectors if required. The signal splitting function is performed at the antenna masthead such that this method reduces the number of feeder cables running up the antenna tower by a factor of N, where N is the number of common frequency signals (e.g., the number of sectors) amplified by the single power amplifier. This invention enables a single power amplifier to simultaneously provide all the radio frequency signals necessary to feed a general N input phased array antenna system and form multiple antenna beams uniquely for several individual users simultaneously.

A method and apparatus for transmitting wireless data to users which increases the wireless capacity for data transmissions within a sector served by a base station is disclosed. Accordingly, the sector is subdivided into a plurality of beams, typically by means of beam forming antennas, and the user data to be transmitted is time division multiplexed by scheduling the data into timeslots for transmission via the beams. Capacity is thus increased by decreasing network interference and/or transmitting data to more than one user at the same time by means of the multiple beams, and time division multiplexing the data. Preferably multiple users can be scheduled on multiple beams simultaneously in order to increase capacity. Preferably the same user can be allocated more than one beam if the radio conditions warrant. Such a system is optimized for data and carries out the following steps: a. Evaluating the reverse link wireless conditions for each user; b. responsive to step a, generating information defining the beam or beams to be utilized by each user; c. generating a Scheduler Metric (SM) for every user; d. scheduling each of the n beams based on the SM and said information for each user; and e. transmitting data scheduled in step d on said n beams.

A polymer waveguide assembly. The assembly includes a polymer waveguide have a plurality of waveguide cores and an associated plurality of lenses respectively. The assembly also includes a molded lens structure having a support region, a primary refractive surface and a secondary refractive lens. The polymer waveguide is positioned onto the support surface of the molded lens structure so that the waveguide lenses are in optical alignment with the primary refractive lens and the secondary refractive lens of the molded waveguide structure. The lenses of the polymer waveguide are capable of collimating in the X and Y directions respectively. The primary refractive lens and the secondary refractive lens are both capable of collimating light in the Z direction. With this arrangement, a substantial; portion of the light passing through the secondary lens toward the waveguide cores is within the acceptance angle of the plurality of waveguides lenses respectively. The secondary lens thus creates a shallow angle of convergence relative to the input of the plurality of lenses of the waveguide. As a result, issues caused by misalignment are minimized and optical coupling is improved.
