Abstract
An amplification subsystem for a communication system includes a downstream amplifier configured to transmit a downstream signal within a first frequency range, an upstream amplifier configured to transmit an upstream signal within a second frequency range, and a bidirectional amplifier configured to selectively transmit a mid-band signal in either of the upstream and downstream direction.
Claims20
An amplification subsystem for amplifying signals traveling between first and second transceivers in a communication system, comprising:
- a first amplifier configured to amplify first signals traveling from the first transceiver to the second transceiver;
- a second amplifier configured to amplify second signals traveling from the second transceiver to the first transceiver;
- and
- circuitry configured to:
- propagate the first signals, within a first frequency band, to the first amplifier,
- selectively propagate the first signals, within a second frequency band that is different from the first frequency band, to the first amplifier,
- propagate the second signals, within a third frequency band, to the second amplifier, and
- selectively propagate the second signals, within a fourth frequency band that is different from the third frequency band, to the second amplifier.
A method for amplifying signals in a communication system, comprising:
- propagating downlink signals, within a first frequency band, to a first amplifier for amplification;
- selectively propagating downlink signals, within a second frequency band that is different from the first frequency band, to the first amplifier for amplification;
- propagating uplink signals, within a third frequency band, to a second amplifier for amplification;
- and
- selectively propagating uplink signals, within a fourth frequency band that is different from the third frequency band, to the second amplifier for amplification.
