Abstract:
A wireless telephone system, comprising:a central transceiver; and first and second remote transceivers in communication with the central transceiver via a broadband distribution network for carrying telephony signals between wireless telecommunication devices and the central transceiver, wherein the first remote transceiver is for handling wireless traffic in a first defined coverage area and the second remote transceiver is for handling wireless traffic in a second defined coverage area, wherein the first and second defined coverage areas overlap, and wherein the first remote transceivers includes: a first circuit for transmitting a telephony signal received from the central transceiver via the broadband distribution network to a mobile telecommunications device, wherein the first circuit includes a first plurality of heterodyne stages coupled between the broadband distribution network and a transmit antenna, wherein each of the first plurality heterodyne stages includes a mixer and an oscillator, each oscillator having an output frequency; a second circuit for transmitting a telephony signal received from the mobile telecommunications device to the central transceiver via the broadband distribution network, wherein the second circuit includes a second plurality of heterodyne stages coupled between a receive antenna and the broadband distribution network, wherein each of the second plurality of heterodyne stages includes a mixer and an oscillator, each oscillator having an output frequency; and a microprocessor in communication with the central transceiver for receiving a first control signal from the central transceiver and, based thereon, for outputting a control signal to each of the oscillators of the first and second plurality of heterodyne stages to change the output frequency of the oscillators such that the first remote transceiver transmits wireless telephony signals to the mobile telecommunications device at the same frequency as the second remote transceiver transmits wireless telephony signals to the mobile telecommunications device, and such that the first remote transceiver receives wireless telephony signals from the mobile telecommunications device at the same frequency as the second remote transceiver receives wireless telephony signals from the mobile telecommunications device.
