摘要： A technology is described for a time division duplex (TDD) repeater with network protection. The TDD repeater can comprise a first port, a second port, and one or more amplification paths coupled between the first port and the second port. The TDD repeater can comprise a signal detector configured to measure a received signal power for a downlink (DL) signal in a first set of one or more TDD DL subframes. The TDD repeater can be further configured to adjust an uplink (UL) noise power or gain of the one or more amplification paths based on the received signal power for the DL signal in the first set of the one or more TDD DL subframes.

摘要： Provided is a method of power control, repeater and storage medium. The repeater is used to amplify cellular communication signals between a base station and a user equipment. The method includes measuring a power of downlink signals received from the base station; estimating a power of uplink signals transmitted from the user equipment, wherein the power of uplink signals is estimated based on the measured power of downlink signals and a power constant, and the power constant is an estimated closed-loop power control constant between the power of downlink signals and the power of uplink signals; and determining a power of uplink signals transmitted to the base station, based on the estimated power of uplink signals. In this method, AGC (Auto Gain Control) can respond quickly and properly, thereby reducing the false response of AGC and improving the repeater performance.

摘要： A system to process antenna-captured OTA-transmitted RF signals for delivery to a receiver within a building includes a pre-amplifier connected to a single antenna, mounted on a mast positioned outside the building, the receiver, and a solar power unit. The solar power unit delivers power to operate the pre-amplifier. The pre-amplifier amplifies the antenna-captured signals before delivering them to the receiver at a carrier to noise ratio above an acceptable threshold, independent of where the receiver is located within the building.

摘要： A wireless communication system includes a first communication device and a second communication device. The first communication device comprises a first digital signal processor (DSP) that obtains a plurality of radio frequency (RF) signals corresponding to different communication protocols from a plurality of communication systems. The first DSP upconverts a frequency of each of the plurality of RF signals to a different frequency. The first DSP maps and aligns the plurality of RF signals corresponding to the different communication protocols in the mmWave RF signal based on a number of source antennas from which the plurality of RF signals are obtained. Furthermore, the first DSP multiplexes the plurality of RF signals corresponding to different communication protocols into a mmWave RF signal of a specified frequency. The first DSP further transmits the mmWave RF signal of the specified frequency along with a defined pilot tone to the second communication device.

摘要： Technology for a repeater configured to perform variable bandwidth filtering of signals is disclosed. The repeater can include a signal path for a radio frequency (RF) signal. The signal path can include a fixed-bandwidth low pass filter (LPF) operable to perform a variable bandwidth filtering of the RF signal to produce a channelized signal. The variable bandwidth filtering at the LPF can be performed by adjusting a first variable local oscillator (LO). The signal path can include a fixed-bandwidth high pass filter (HPF) operable to perform a variable bandwidth filtering of a channelized signal output from the LPF. The variable bandwidth filtering at the HPF can be performed by adjusting a second variable LO. The first variable LO and the second variable LO can be set to create a variable bandwidth that enables the repeater to perform variable bandwidth filtering of the signals.
