    摘要: A distributed antenna system includes a plurality of remote antenna units with a passive element coupled to at least one of the remote antenna units at a connection juncture. An RFID system is associated with the first passive element and has RFID data identifying the first passive element. An interrogator unit is associated with the remote antenna unit and is configured for generating a least one signal for transmission to the passive element to be reflected at the connection juncture and received at the interrogator unit. The interrogator unit is also configured for generating at least one signal for transmission to the RFID system to obtain the RFID data identifying the passive element. Processing circuitry processes the reflected signal and measures a parameter of the first passive element. The processing circuitry correlates the measured parameter with the RFID data for the passive element.

    摘要: Certain features relate to a centralized radio access network (C-RAN) that can flexibly and dynamically allocate protocol layer processing among baseband processing units and remote units. A C-RAN can be configured to include a media access control (“MAC”) scheduler and a fronthaul physical layer coordinator. The fronthaul physical layer coordinator can include a fronthaul physical layer scheduler, which can allocate spatial resources by determining the specific remote unit(s) that should serve a given mobile device. The MAC scheduler can allocate time/frequency resources to user devices communicating with the remote units. The fronthaul physical layer coordinator or the MAC scheduler can also determine the optimal transmission modes remote units can use to serve the user devices.

    摘要: A method of tuning a production module using a reference module with virtual gain correction is provided. The method includes selecting a counterpart reference module created for a select application. The production module is commutatively coupled to the selected counterpart reference module to generate a production module pair. A production module gain curve for the production module pair is measured for each frequency band to be used by the production module. The production module is tuned based at least in part on offset gain values at select number of frequency observation points for each frequency band associated with the counterpart reference module and gain values at the select number of frequency observation points of the measured production module gain curve for each frequency band.
