    摘要: Systems and methods are provided for automatically detecting passive components in communications systems using radio frequency identification ("RFID") tags. A coupling circuit is provided in a system between a communications network and an RFID tag. The RFID tag is associated with a passive element of a distributed antenna system ("DAS"). The coupling circuit can allow an RFID signal received from an RFID transmitter over the communications network to be transported to the RFID tag. The coupling circuit can substantially prevent mobile communication signals on the communications network from being transported to the RFID tag.

    摘要: Certain aspects involve a wideband remote unit. The wideband remote unit can include one or more antennas and an analog-to-digital converter ("ADC"). The antenna can receive wideband signals. The wideband signals can include an uplink RF signal and a leaked downlink RF signal. The uplink RF signal can have an uplink signal power at or near a noise level. The leaked downlink RF signal can have a downlink signal power greater than the uplink signal power. The ADC can convert the received wideband signals to digital RF signals representing the uplink signal and the downlink signal. The wideband remote unit can transmit the digital RF signals to a unit of a DAS that is in communication with a base station.

    摘要: The sensor network 30 may include a location capture processing unit 38; and a plurality of sensors 10, 14, 32a - 321 in communication with the location capture processing unit 38. Each sensor 32a - 321 of the plurality of sensors 32a - 32l includes a controller 306 and a RF receiver 100 configured to receive RF signals. The RF receiver 100 is in communication with the controller 306. A localization engine 300 is configured to receive beacon signals transmitted by other sensors 10, 14, and 32a - 321 in the sensor network 30. The localization engine 300 is in communication with the controller 306. The controller 306 of each of the plurality of sensors 32a - 321 is further configured to determine a position of its respective sensor 32a - 32l using either RF receiver 100 or localization engine 300 or both. The plurality of sensors 32a - 32l communicates their position to the location capture processing unit 38.

    摘要: A system is provided for adjusting power provided over a channel to a device. The system can include power sourcing equipment and a sub-system. The power sourcing equipment can provide power to a powered device via a channel (302). The sub-system can determine an amount by which to increase the power based on a resistance of the channel (306). The power sourcing equipment or the powered device can adjust the power (or load) in response to a command from the sub-system. The sub-system can include at least one measurement device and a processor. The measurement device can measure an output voltage of the power sourcing equipment, an input voltage of the powered device, and a current on the channel (304). The processor can determine the resistance of the channel based on the output voltage, the input voltage, and the current. The processor can output a command specifying an increase or decrease in the level of power supplied by the power sourcing equipment.

    摘要: Certain aspects and features of the present disclosure relate to a validation sub-system for determining whether access points in a telecommunication system provide suitable performance for a specified configuration of the telecommunication system. For example, a wireless receiver can simultaneous receive beacon signals at a common frequency from multiple access points. Each beacon signal has a data sequence that is different than the other beacon signals. A processing device can determine, based on the data sequences received by the wireless receiver, channel responses for channels between the access points and the wireless receiver. The processing device can output, based on the channel responses, an indicator that the access points are suitable for a specified configuration of a telecommunication system for providing wireless coverage using the access points.

    摘要: A distributed antenna system having improved data transmission features incorporates endpoints 18, 20 of the system, which are coupled together by serial data link 22. At the endpoints, processing may occur utilizing processing circuitry 56, 58 to determine similarities between multiple signal streams r1, r2. If the streams are similar, the data sent over the serial digital link is reduced by only sending one of the representative signals. In an alternative embodiment of the invention, the difference between the signals might be sent as well. Alternatively, all signals might be sent, but may be compressed with compression circuitry 176, 230, 240 before the signals are transmitted over the serial link. At the endpoint of the system, the signals are reconstructed for further processing and transmission.

    摘要: A telecommunications system is provided that includes a unit for communicating channelized digital baseband signals with remotely located units. The channelized digital baseband signals include call information for wireless communication. The unit includes a channelizer section and a transport section. The channelizer section can extract, per channel, the channelized digital baseband signals using channel filters and digital down-converters. The transport section can format the channelized digital baseband signals for transport together using a transport schedule unit for packetizing and packet scheduling the channelized digital baseband signals. A signal processing subsystem can control a gain of uplink digital baseband signals, independently, that are received from the remotely located units prior to summing the uplink digital baseband signals.
