Abstract
A frequency offset device can be located at a remote unit of a distributed antenna system and can be configured to combine two or more RF bands to allow the remote unit to process signals otherwise associated with a total RF bandwidth beyond the capabilities of the remote unit to process simultaneously. Signals of the RF bands are received at the unit. At least one of the RF bands is shifted to form a composite RF band that has an edge of a first RF band overlapping an edge of a second RF band. The composite RF band includes information from the signals of the first RF band and from the signals of the second RF band. The remote unit can process the composite RF band.
Claims19
A method comprising:
- receiving signals of a first RF band and signals of a second RF band at a remote unit of a distributed antenna system;
- positioning in frequency the first RF band to form a composite RF band, the composite RF band having an edge of the first RF band overlapping an edge of the second RF band, the composite RF band including information from the signals of the first RF band and from the signals of the second RF band;
- and
- processing the composite RF band at the remote unit.
A system comprising:
- a remote unit of a distributed antenna system that includes a head-unit unit, the remote unit being configured for receiving signals of a first RF band and signals of a second RF band from a coverage zone;
- and
- a frequency offset device associated with the remote unit, the frequency offset device being configured for positioning in frequency at least one of the first RF band or the second RF band to form a composite RF band having an edge of the first RF band overlapping an edge of the second RF band, the composite RF band including information from the signals of the first RF band and from the signals of the second RF band,
- wherein the remote unit is configured for processing the composite RF band prior to transmitting the composite RF band to the head-end unit.
A distributed antenna system, comprising:
- a head-end unit to transceive signals with a base transceiver station, a first remote unit, and a second remote unit;
- the first remote unit positioned for providing wireless coverage for a first coverage zone;
- and
- the second remote unit positioned for providing wireless coverage for a second coverage zone, the second remote unit including circuitry for receiving signals of a first RF band and signals of a second RF band, the second remote unit including a frequency offset device configured for positioning in frequency at least one of the first RF band or the second RF band to form a composite RF band having an edge of the first RF band overlapping an edge of the second RF band, the composite RF band including information from the signals of the first RF band and from the signals of the second RF band, the second remote unit being configured for processing the composite RF band prior to transmitting the composite RF band to the head-end unit.
