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.
Claims1
A remotely reconfigurable remote radio head unit for transporting radio frequency signals, the remotely reconfigurable remote radio head unit comprising:
- at least one remotely reconfigurable access module adapted to receive reconfiguration parameters from a remote location,
- a plurality of band modules, each of the plurality of band modules having separately reconfigurable parameters in response to the reconfiguration parameters received from the at least one remotely reconfigurable access module, each of the plurality of band modules supporting one of a plurality of frequency bands of the radio frequency signals being transported, and
- an interface adapted to provide electrical and mechanical connection for mounting the plurality of band modules for providing bidirectional communication between the at least one remotely reconfigurable access module and each of the plurality of band modules.
