  • Power transmission system for wireless communication systems
    Patent number: 10812664
    Abstract: A power transmission system includes a voltage measurement device located on a tower or rooftop for measuring a voltage (VRRH) at a top end of a DC cable connected to a remote radio head (RRH). A voltage control system receives an input voltage (VIN) from a DC power supply and generates an output voltage (VOUT) at a base end of the DC cable. The voltage control system calculates a voltage drop on the DC cable based on the VRRH measurement and then adds different voltage steps to VIN so VOUT compensates for the voltage drop. Calculating the voltage drop allows the PTS to more efficiently supply power to RRHs without having to increase the size of DC power cables.
