    Abstract: PROBLEM TO BE SOLVED: To provide a mobile wireless terminal in a plurality of concurrently operating communication links set up to properly control aggregate input and/or output power of a transmission signal amplifier to avoid distortion and maximize an overall communication bandwidth.
    SOLUTION: A mobile wireless terminal (MWT) includes multiple wireless modems. The multiple modems have their respective transmission outputs combined together and input into a transmission signal amplifier to produce an aggregate transmission output. The MWT is constrained to operate within a single aggregate transmission power limit. Each of the multiple modems has an individual transmission power limit related to the aggregate transmission power limit. An MWT controller adjusts the individual transmission power limits in the multiple modems based on the aggregate transmission power limit (702) of the MWT and respective transmission power estimates (712) reported from the multiple modems, to cause each individual transmission power limit to track corresponding individual modem transmission power.

    Abstract: A compact, low cost antenna communicates with low and medium earth orbit satellites. The antenna includes a plurality of micro-strip elements arranged about an axis and positioned to illuminate upper elevation angles. The micro-strip elements are perpendicular to each other and are oriented toward the horizon at 90 degree increments. Furthermore, the micro-strip elements are tilted at a 50 degree angle. A quadrifilar helix is positioned at the center of the micro-strip elements and positioned to illuminate lower elevation angles. The micro-strip elements generate an omni-directional field pattern in the azimuth plane. The quadrifilar helix generates a high-gain, narrow beam-width field pattern that is also omni-directional in the azimuth plane. The antenna provides improved immunity to specular ground reflections by limiting reception of signals below a threshold elevation angle. Also, the antenna provides continuous, uninterrupted communications by eliminating "dead" period associated with conventional parabolic dish antennas.

    Abstract: A mobile wireless terminal (MWT) includes multiple wireless modems. The multiple modems have their respective transmit outputs combined to produce an aggregate transmit output. The multiple modems can concurrently transmit data in a reverse link direction and receive data in a forward link direction. The MWT is constrained to operate under an aggregate transmit power limit. Each of the multiple modems has an individual transmit limit related to the aggregate transmit power limit. When operating, over-limit ones of the multiple modems are deactivated and then reactivated to keep an aggregate transmit power of all of the modems below the aggregate limit, and to maximize data through-put on the forward and reverse links.
