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.
