摘要： The invention is directed to a method and system for supporting wireless RF services over a wired digital data network infrastructure, such as an Ethernet network. The system includes a control unit that can be connected to a base station that supports one or more wireless RF services. The control unit converts the wireless RF signals to an intermediate frequency (IF) that does not interfere with the data network signals and combines the IF signals onto the cable run to a remote network device on the digital data network. The remote network device includes a multiplexer or a low pass filter and a high pass filter that separates the IF signals from the digital data signals on the downlink and combines the IF signals with digital data signals on the uplink over the cable run. The IF signals can be input to an RF module connected to the remote network device which converts the IF signals back to the original RF signals for transmission by a transceiver to wireless devices. Similarly, on the uplink, RF signals received from the wireless devices through the transceiver can be converted to IF for transmission over the cable run to the base station. In one conventional data network each cable run includes 4 pair of conductors and each pair can be used to carry a different IF frequency band. In addition, each pair can be configured to carry more than one IF frequency band using FDD or TDD. Additional signaling channels, such as for management signaling can be provided using differential signaling between 2 pair of conductors. The filters can be implemented using various technologies, including silicon, LTCC and discrete components and active filters can be provided to allow for configuring and tuning of performance in the field.
