摘要

This disclosure describes techniques to identify and mitigate an effect of a power interruption that impacts the operation of Radio Frequency (RF) antennas associated with a telecommunications network. More specifically, an Adaptive Voltage Modification (AVM) controller is described that is configured to monitor and detect a change in voltage that occurs during a power transmission from a Direct Current (DC) power source to a Remote Radio Unit (RRU). A power interruption may include a power disruption or a power surge. The AVM controller may be configured to cause a potential transformer that is coupled between the DC power source and the RRU to incrementally step-up or step-down the voltage of a power transmission from the DC power source. In this way, the AVM controller may preemptively mitigate an impact of a power interruption on Quality of Service (QoS) parameters associated with signal data transmitted by the RF antennas.

Moreover, the one or more network(s) 118 may include public networks such as the Internet, private networks such as an institutional and/or personal intranet, or some combination of private and public networks. The one or more network(s) can also include any type of wired and/or wireless network, including but not limited to local area network (LANs), wide area networks (WANs), satellite networks, cable networks, Wi-Fi networks, Wi-Max networks, mobile communications networks (e.g. 3G, 4G, and so forth), or any combination thereof.

FIG. 2 illustrates a block diagram of various components of an Adaptive Voltage Modification (AVM) controller. The AVM controller 202 may include routines, program instructions, objects, and/or data structures that perform particular tasks or implement abstract data types. Further, the AVM controller 202 may include input/output interface(s) 204. The input/output interface(s) 204 may include any type of output interface known in the art, such as a display (e.g. a liquid crystal display), speakers, a vibrating mechanism, or a tactile feedback mechanism. Input/output interface(s) 204 also include ports for one or more peripheral devices, such as headphones, peripheral speakers, or a peripheral display. Further, the input/output interface(s) 204 may further include a camera, a microphone, a keyboard/keypad, or a touch-sensitive display. A keyboard/keypad may be a push button numerical dialing pad (such as on a typical telecommunication device), a multi-key keyboard (such as a conventional QWERTY keyboard), or one or more other types of keys or buttons, and may also include a joystick-like controller and/or designated navigation buttons, or the like.
