  • Transmitter using frequency hopping for mobile communications systems
    Patent number: 6850765
    Abstract: A transmitter for transmitting RF data in an RF communication network using a plurality of carrier frequencies is described. The transmitter has a data splitter for receiving an information signal at an intermediate frequency lower than the carrier frequency, and two transmitter paths each having an input connected to the data splitter and each having a frequency modulator for upconverting the intermediate frequency to a respective carrier frequency, the carrier frequency being individually selectable for each transmitter path.

  • Data delivery over a cellular radio network
    Publication number: 20020025826
    Abstract: A broadband digital broadcast 1 network is described in which the cellular topology is dynamically configurable to maintain spectral efficiency. The reconfiguration of the topology occurs in response to changes in the demand for content. Thus, a single cell could be defined to cover an area in which the same content is being delivered to a substantial number of users. Conversely, a large number of cells could be defined to cover an area in which a substantial number of users are each having different content delivered to them.
