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 method for managing base station power, comprising:
collecting data impacting power management profile for a multiple-in, multiple-out (MIMO) antenna site;
generating a power management profile based on the collected data;
collecting current data to apply to the power management profile; and
applying data to the power management profile and scheduling a MIMO leg's on/off schedule based on the numbers of users served and other access stations in the cell area;
wherein when an update to the power management profile is needed then repeating the steps of:
generating a power management profile based on the collected data;
collecting current data to apply to the power management profile; and
applying data to the power management profile and suggesting an action related to a leg of the MIMO; and
wherein when an update to the power management profile is not needed then repeating the steps of:
collecting current data to apply to the power management profile; and
applying data to the power management profile and suggesting an action.
2. The method of claim 1 further comprising determining whether an update to the power management profile is needed.
3. The method of claim 1 further comprising a user considering factors that impact electrical power usage, the factors including at least one of: a number of users serviced by the wireless fronthaul access point; distance from other wireless base stations; power consumption by individual components including power amplifiers, base stations, processors, and other system components; traditional weather pattern in the region; number of solar panels and power generated by solar panels, standby power supply and its current capacity and condition; and a scheduling algorithm that relaxes a need to keep the power amplifiers on continuously.
4. The method of claim 1 wherein the generating a power management profile is based on variables including at least one of: current weather; number of users; time of the day; day of the week; effect of scheduling algorithms; and a number of solar panels needed to produce electrical energy needed based on weather pattern.
5. The method of claim 1 wherein determining whether an update to the power management profile is needed further comprises updating when collected data indicates that the power management profile needs to be updated based on changes in the data that are outside of previously observed pattern, and data that is inapplicable to generate correct predictions and instructions.
