Abstract: Power distribution modules in distributed antenna systems include fan monitoring circuits for indicating an alarm condition to head-end equipment. The alarm condition can be used by system operator/owners that a fan is drawing excessive power, thereby detracting from system performance, or indicating that the fan may fail. The alarm condition signal can be returned to the head-end equipment via an uplink communication path between a remote unit powered by the module and the head-end equipment.

Abstract: A wireless signal in a frequency band is shifted to another distinct band, and carried in the shifted band to another location, wherein the wireless signal is shifted back to the original frequency band. The frequency shifting can employ conventional frequency shifting schemes such as mixer/filter and heterodyne. In one embodiment the wireless signal is frequency shifted by converting it to other representing signals (such as I/Q components) and forming the frequency-shifted signal from the representations. The system is may be used to increase in-door or outdoor coverage, as well as bridging between in-door and outdoor networks. The medium may use dedicated wiring or existing service wiring in a residence or building, including LAN, telephone, AC power and CATV wiring. The system can be enclosed as a stand-alone unit, housed in integrated form as part of a service outlet or as a snap-on/plug-in module.

Abstract: A system and method for measuring a characteristic impedance of a transmission-line comprises transmitting energy to the line, and shortly after measuring the voltage/current involved and thus measuring the equivalent impedance. The measured characteristic impedance may then be used in order to determine the termination value required to minimize reflections. In another embodiment, the proper termination is set or measured by adjusting the termination value to achieve maximum power dissipation in the terminating device. The equivalent characteristic impedance measurement may be used to count the number of metallic conductors connected to a single connection point.

Abstract: A system for providing DC power on local telephone lines, such as telephone lines in a building or office, for powering devices and circuitry associated with communications over those telephone lines, as well as other functions. Desired voltage and power levels are supplied over local telephone lines by separating the DC power component from the central office or private branch exchange with a DC blocking filter while passing all AC telephony signals. A distinct DC power is then imposed over the telephone line for powering both the telephony service as well as other loads. Conventional telephone off-hook detection is simulated for compatibility with the central office or private branch exchange. The functions required may be integrated, partially or fully within a telephone outlet.

Abstract: 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.
