Abstract: Selective radiation of radio frequency (RF) reference beams in a wireless communications system (WCS) based on user equipment (UE) locations is disclosed. The WCS may include a radio node that communicates RF communications signals in a coverage area via RF beamforming. Thus, the radio node is required to periodically radiate a number of RF reference beams in different directions of the coverage area to help UEs to identify a best-possible RF beam(s). However, radiating the RF beams in different directions periodically can increase power consumption of the radio node, particularly when the UEs are concentrated at a handful of locations in the coverage area. In this regard, the radio node can be configured to selectively radiate a subset of the RF reference beams based on a determined location(s) of the UE(s) in the coverage area, thus making it possible to reduce computational complexity and power consumption of the radio node.

Abstract: Systems and methods for efficient power conversion in a power supply in a power distribution system are disclosed. In particular, a low frequency transformer having high conversion efficiency is coupled to an input from a power grid.

The size and cost of the cabinet containing the power conversion circuitry is minimized, and operating expenses are also reduced as less waste energy is generated.
