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.
Abstract translation: 公开了一种用于在分布式天线系统中实现高数据速率通信的远程无线电头单元（RRU）系统。 分布式天线系统配置为中性主机，使多个操作员能够存在于一个DAS系统上。 本公开使得远程无线电头单元能够是现场可重新配置的并且支持多调制方案（与调制无关），多载波，多频带和多信道。 因此，远程无线电头系统特别适用于诸如基站，中继器和室内信号覆盖系统之类的无线传输系统。

Abstract: A distributed antenna system includes a master unit including a downlink RF input operable to receive an RF input signal from a downlink port of a base station, a first optical port, and a second optical port. The distributed antenna system also includes a first remote unit coupled to the first optical port. The first remote unit comprises a downlink antenna port and a first uplink antenna port and a second remote unit coupled to the second optical port of the master unit. The second remote unit comprises a downlink antenna port and a second uplink antenna port. The master unit is operable to transmit a first RF signal associated with the first RF uplink signal to a first uplink port of the base station and transmit a second RF signal associated with the second RF uplink signal to a second uplink port of the base station.
