摘要： Certain aspects are directed to a configuration sub-system for telecommunication systems. The configuration sub-system can include a test signal generator, a power measurement device, at least one additional power measurement device, and a controller. The test signal generator can be integrated into components of a telecommunication system. The test signal generator can provide a test signal to a signal path of the telecommunication system. The power measurement device and the additional power measurement device can respectively be integrated into different components of the telecommunication system. The power measurement device and the additional power measurement device can respectively measure the power of the test signal at different measurement points in the signal path. The controller can normalize signals transmitted via the telecommunication system by adjusting a path gain for the signal path based on measurements from the power measurement device and the additional power measurement device.

摘要： Certain aspects and features are directed to determining characteristics such as phase margin and gain margin of signals such as standardized orthogonal frequency-division multiplexing (“OFDM”) signals. In one aspect, a processing system can identify multiple carriers in an OFDM signal communicated by a repeater. The carriers include carriers from frequency guard band other than those used for communicating payload data or pilot data. The processing system can generate dynamic characteristic data to be sent via the carriers. The processing system can generate modulate the carriers with the dynamic characteristic data. The modulated power level of the carriers is less than a maximum level of noise filtered by a device receiving the OFDM signal.

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.

摘要： Techniques are provided to more accurately determine reflected power, reflection coefficient, and/or voltage standing wave to permit prompt protection of components such as power amplifiers and notify communication system operators. This is accomplished by more accurately determining an amplitude and phase of an output reflected signal at an output port of a bidirectional coupler as a function of the following: an amplitude and a phase of a coupled forward signal coupled into a forward coupled port of the bidirectional coupler; an amplitude and a phase of a coupled reverse signal coupled into a reverse coupled port of the bidirectional coupler; an electrical transmission parameter from an input port of the bidirectional coupler to the forward coupled port; an electrical transmission parameter from the input port to the reverse coupled port; and an electrical transmission parameter from an output port of the bidirectional coupler to the reverse coupled port.

Each respective radiating point includes a detector configured to evaluate uplink signals received from a coverage area of the respective radiating point. The detector is further configured to determine which services of a plurality of services supported by the system are needed and which services of the plurality of services supported by the system are not needed based on the evaluation of the uplink signals. The detector is further configured to send a request, to the central unit, to activate a service determined to be needed.

摘要： A telecommunications system can include analog-to-digital converters in an uplink communication path or a downlink communication path. The analog-to-digital converters can have a high dynamic range and bandwidth to obviate a need for down-conversion of signals using an analog mixer. The uplink communication path and the downlink communication path can be coupled to an antenna using a non-duplexer coupling device. Uplink signals traversing the uplink communication path can be isolated from downlink signals independent of using a duplexer.
