Abstract
A remote radio head unit (RRU) system for achieving high data rate communications in a Distributed Antenna System is disclosed. The Distributed Antenna System is configured as a Neutral Host enabling multiple operators to exist on one DAS system. The present disclosure enables a remote radio head unit to be field reconfigurable and support multi-modulation schemes (modulation-independent), multi-carriers, multi-frequency bands and multi-channels. As a result, the remote radio head system is particularly suitable for wireless transmission systems, such as base-stations, repeaters, and indoor signal coverage systems.
Claims6
A remotely reconfigurable remote radio head unit for transporting radio signals comprising
- at least one remotely reconfigurable access module adapted to receive uplink radio frequency signals, to output downlink radio frequency signals, and further adapted to receive reconfiguration parameters from a remote location,
- one or more band modules, each band module having separately reconfigurable parameters in response to signals received from the access module, and
- an interface adapted to provide electrical and mechanical connection for mounting the one or more band modules for providing bidirectional communication between the at least one access module and the one or more band modules.
