Abstract
One embodiment is directed to a master unit for a distributed antenna system (DAS). The master unit comprises one or more donor cards and one or more transport cards, and at least one passive backplane. Each passive backplane comprises a plurality of backplane connectors. Each backplane connector is configured to connect a respective donor card or transport card to the passive backplane. Each backplane connector is connected to each of the other connectors via one or more respective passive bi-directional backplane channels. The master unit is configured so that all active processing of streams of digital samples transported via the DAS is performed by the donor cards and transport cards and not the passive backplane.
Claims34
A master unit for a distributed antenna system (DAS) that also includes a plurality of remote antenna units, each remote antenna unit serving one or more base stations, the master unit comprising:
- one or more donor cards, each donor card configured to couple that donor card to at least one base station;
- one or more transport cards, each transport card configured to couple that transport card to one or more sets of remote antenna units;
- and
- at least one passive backplane, each passive backplane comprising a plurality of backplane connectors, wherein each of the backplane connectors is configured to connect a respective donor card or transport card to that passive backplane, and wherein each of the backplane connectors is connected to each of the other connectors via one or more respective passive bi-directional backplane channels;
- wherein the master unit is configured so that all active processing of streams of digital samples transported via the DAS is performed by the donor cards and transport cards and not the passive backplane.
A distributed antenna system (DAS) comprising:
- a master unit coupled to one or more base stations;
- and
- a plurality of remote antenna units, each remote antenna unit serving one or more of the base stations;
- wherein the master unit comprises:
- one or more donor cards, each donor card configured to couple that donor card to at least one base station;
- one or more transport cards, each transport card configured to couple that transport card to one or more sets of remote antenna units;
- and
- at least one passive backplane, each passive backplane comprising a plurality of backplane connectors, wherein each of the backplane connectors is configured to connect a respective donor card or transport card to that passive backplane, and wherein each of the backplane connectors is connected to each of the other connectors via one or more respective passive bi-directional backplane channels;
- wherein the master unit is configured so that all active processing of streams of digital samples transported via the DAS is performed by the donor cards and transport cards and not the passive backplane.
