Base station power management using solar panel and battery forecasting
A system is disclosed, comprising: a solar panel; an electric power supply source; a wireless fronthaul access point coupled to a radio mast and in communication with a remote baseband unit, the wireless fronthaul access point further comprising a first millimeter wave wireless interface; a self-organizing network module in communication with a coordinating server; and an antenna-integrated radio for providing access to user equipments (UEs), mounted within line of sight on the radio mast with the wireless fronthaul access point, the antenna-integrated radio further comprising: a second millimeter wave wireless interface configured to receive the digital I and Q signaling information from the remote baseband unit wirelessly via the wireless fronthaul access point, wherein the wireless fronthaul access point thereby wirelessly couples the remote baseband unit and the antenna-integrated radio. Synchronization is used to pack used resource blocks to reduce the duty cycle of the PAs, thereby reducing power.
1. A base station power management system, comprising:
an antenna-integrated radio for providing access to user equipments (UEs), the antenna-integrated radio further comprising: an interface configured to receive digital I and Q signaling information from a remote baseband unit, and, a self-organizing network (SON) module;
a power source electrically coupled to the antenna-integrated radio, wherein the power source includes a solar panel array and a battery, and wherein the power source provides information to the SON module; and
a coordinating server in a mobile operator core network that is in communication with the SON module and configured to receive data for creating a power management profile at the coordinating server and configured to send instructions to the antenna-integrated radio based on the power management profile.
2. The base station power management system of claim 1 , wherein the battery provides required electrical power during cloudy weather when solar panels may not produce sufficient electrical power.
3. The base station power management system of claim 1 , wherein battery voltage and charge status information is used to determine availability of power.
4. The base station power management system of claim 3 , wherein the coordinating sever compares a tentative electrical power produced by solar panels and the batteries based on the present and forecasted weather condition to the total power needed for the operation.
5. The base station power management system of claim 1 , wherein battery power is be reserved for the radio and not for processing systems.
6. The base station power management system of claim 1 , wherein the power management profile associates electrical power needed with factors that may impact the required electrical power; the factors including weather conditions affecting generation of power by the solar panels, standby or storage battery status and voltage condition.
7. The base station power management system of claim 1 , wherein the power management profile may also generate a schedule of power availability from sources such as the solar panel array, the battery, and an off-grid power supply.
