Booster gain adjustment based on user equipment (UE) need
A technology is described for adjusting repeater gain based on user equipment need. A repeater can be configured to receive a downlink signal strength indicator value of a user equipment (UE) via a wireless connection of the UE with the repeater. The repeater can be further configured to select a threshold value for the downlink signal strength indicator value. The repeater can be further configured to reduce or bypass a downlink repeater gain level when the downlink signal strength indicator value is greater than the threshold value.
High gain relay antenna system with multiple passive reflect arrays
Examples disclosed herein relate to a high gain relay antenna system that includes a first passive reflect array configured to receive electromagnetic radiation from a transmitting source and generate a transmit beamforming signal with a first gain from the electromagnetic radiation. The high gain relay antenna system also includes a second passive reflect array positioned at a predetermined distance from the first passive reflect array and configured to collimate phases of the transmit beamforming signal from the first passive reflect array and transmit an outbound beamforming signal with a second gain greater than the first gain, to a coverage area. Other examples disclosed herein relate to a dual-reflect array system and a method of high gain relay with multiple passive reflect array antennas.
SYSTEM AND METHOD FOR CONTROLLING TRANSMISSION POWER BY A NEXT GENERATION NEW RADIO REPEATER
A method, device, and computer-readable medium provide for establishing, by a repeater device, a communication channel with a fixed wireless access (FWA) device; receiving, by the repeater device, reference signals from a wireless station; forwarding, by the repeater device, the reference signals to the FWA device; transmitting, by the repeater device, a first uplink signal from the FWA device using a first transmission power level to the wireless station, wherein the first transmission power level is a predetermined value; receiving, in response to the first uplink signal, transmit power control (TPC) command parameters from the FWA device via the communication channel; adjusting, by the repeater device and based on the first TPC command parameters, the first transmission power level from the predetermined value to an adjusted value; and transmitting, at the adjusted transmission power level, a second uplink signal from the FWA device to the wireless station.
Adjusting Repeater Gain Based on Antenna Feedback Path Loss
Technology for a repeater is disclosed. The repeater can include a first port and a second port. The repeater can include a transmitter communicatively coupled to the first port and a receiver communicatively coupled to the second port. The transmitter can transmit a path loss signal. The receiver can receive the path loss signal transmitted by the transmitter. The repeater can include a controller. The controller can identify a first power level of the signal transmitted from the transmitter. The controller can identify a second power level of the signal received at the receiver. The controller can determine an antenna feedback path loss of the repeater based on the first power level and the second power level. The controller can set a maximum gain level for the repeater based on the antenna feedback path loss to avoid an oscillation in the repeater.
Phase noise removal in a network of radio frequency (RF) repeaters
An network of wireless RF repeaters includes a first communication device and a second communication device. The first communication device obtains a plurality of radio frequency (RF) signals corresponding to different communication protocols from a plurality of communication systems. A frequency of each of the plurality of RF signals is upconverted to a different frequency, which introduces a phase noise in the plurality of RF signals. The plurality of RF signals corresponding to different communication protocols are merged into a mmWave RF signal of a specified frequency and a defined pilot tone is inserted into the mmWave RF signal. The second communication device captures the mmWave RF signal having the defined pilot tone over-the-air. At least one RF signal is down converted to a source frequency and the phase noise in the one extracted RF signal is reduced concurrently based on a reference of the defined pilot tone.
