  • Publication number: 20020114038
    Abstract: A method for transferring information within a cellular communications network (20), consisting of transmitting an optical carrier from a first network-element (26A) of the network, modulating the optical carrier (57, 59) with the information, and detecting the modulated optical carrier in an avalanche photo-diode (APD) (150) in a second network-element (24A) of the network so as to recover the information. The method includes altering a gain of the APD responsive to a level of the optical carrier so as to prevent saturation of the APD. Other methods and apparatus are also provided for transferring the information via the optical carrier, and also for using the information transferred.

  • Publication number: 20020055371
    Abstract: Apparatus for transferring information within a cellular network, including a base-station transceiver system (BTS) positioned at a first location, and an antenna assembly, positioned at a second location remote from the first location. The BTS includes communication control circuitry which generates down-link radio-frequency (RF) signals and processes up-link RF signals, and first transducer circuitry which modulates a first beam of unguided electromagnetic radiation with the downlink RF signals and demodulates a second beam received from the antenna assembly to recover the up-link signals.
