Abstract

The present invention describes a method and system for relaying telecommunication signals. The system comprises: a central hub connectable to one or more base stations; a plurality of remote units for relaying the telecommunication signals; and a plurality of expansion units digitally connected to the central hub and connectable to the plurality of remote units. At least one of the plurality of expansion units is provided with a plurality of coverage area modules, wherein one or more of the plurality of remote units is connected to a selected one of the plurality of coverage area modules, the selected one of the coverage area modules being adapted to relay the same signals to the connected one or more of the plurality of remote units.

Claims

1. A system for relaying telecommunication signals, comprising:

a central hub connectable to one or more base stations;

a plurality of remote units for relaying the telecommunication signals; and

a plurality of expansion units digitally connected to the central hub and connect-able to the plurality of remote units,

wherein at least one of the plurality of expansion units is provided with a plurality of coverage area modules, wherein one or more of the plurality of remote units is connected to a selected one of the plurality of coverage area modules, the selected one of the coverage area modules being adapted to relay same signals to the connected one or more of the plurality of remote units,

wherein a connection between the plurality of expansion hubs and the plurality of remote units is reconfigurable, and so that at least one of the remote units may be connected from a first selected one of the coverage area modules, to a second selected one of the coverage area modules.

2. The system of claim 1, wherein relayed signals are digital wideband signals.

3. The system of claim 1 or 2, wherein a digital-to analog converter is located at least one of the plurality of remote units to convert relayed signals from a digital format to an analog format.

4. The system according to claim 1, wherein a number of coverage area modules is less than a number of remote units.

5. The system of claim 1, wherein the central hub is adapted to define at least one carrier bundle from ones of the telecommunication signals and to pass the at least one carrier bundle to at least one of the coverage areas modules.

6. The system of claim 1, further comprising a plurality of gain units (for weighting the relative gain of signals between the central hub (20;

520) and the plurality of expansion units.

7. A method for relaying telecommunication signals comprising the steps of:

receiving telecommunications signals from at least one network operator by a central hub;

generating one or more carrier bundles of the telecommunications signals in the central hub;

passing the one or more defined carrier bundles to a plurality of expansion units, wherein the plurality of expansion units are digitally connected to the central hub and connectable to the plurality of remote units provided with a plurality of coverage area modules, wherein at least one of the plurality of expansion units is provided with a plurality of coverage area modules, wherein one or more of the plurality of remote units is connected to a selected one of the plurality of coverage area modules, the selected one of the coverage area modules being adapted to relay same signals to the connected one or more of the plurality of remote units;

associating a passed one of the defined carrier bundles with an associated coverage areas; and

passing the carrier bundle to remote units for relaying of the radio signals to the associated coverage area,

reconfiguring a connection between the plurality of expansion units and the plurality of remote units, so that at least one of the remote units is connected to a first selected one of the coverage area in a first configuration and is connected to a second selected one of the coverage area in a second configuration.

8. The method of claim 7, wherein the associating of the passed one of the defined carried bundles with an associated coverage area is carried out in the digital domain.

9. The method of claim 7 or 8, wherein at least one of the carrier bundles (comprise telecommunications signals from a plurality of the network operators.

10. The method of claim 7, further comprising applying a relative gain to at least one of the carrier bundles.

11. The method of claim 7, further comprising applying a gain to relayed radio signals.

12. The method of claim 7, further comprising digital to analog conversion of the carrier bundle in the remote units.
