Abstract
A bandwidth management system for a remote repeater network for modifying a first signal to create a second signal within the bandwidth of a communications link, transferring the second signal across the communications link, and reconstructing the first signal at the remote end of the communications link. The bandwidth management system featuring several mixing modes for performing the signal conversion and reconstruction. The system offering a calibration feature to correct for phase distortions introduced in reconstruction of the original signal. The calibration feature incorporating signals from a global positioning satellite system for reconstruction.
Claims12
A communication system for a repeater network, comprising:
- a first repeater site including:
- a first multiplexer having a passband P;
- a first microwave transceiver;
- and
- a first frequency translation system translating first data signals outside of the passband P into second data signals within the passband P;
- a second repeater site including:
- a second multiplexer;
- a second microwave transceiver;
- and
- a second frequency translation system extracting the first data signals from the second data signals;
- and
- wherein the second repeater site communicates with the first repeater site over a microwave link using the first microwave transceiver and the second microwave transceiver, and wherein the first data signals include subaudible control signals used in the repeater network.
