Apparatuses and methods for wirelessly charging electronic devices are provided. The apparatuses and methods disclosed herein may wirelessly charge electronic devices by causing a power distribution device to send a group short beacon signal to a plurality of micro-PTU-coils; identifying a load on a first micro-PTU-coil of the plurality of micro-PTU-coils using a detected magnetic flux caused by an object being proximate to the first micro-PTU-coil; determining a location of the object using the identified load on the first micro-PTU-coil; causing the power distribution device to send a group long beacon signal to the plurality of micro-PTU-coils; receiving, from the object, an advertisement, the advertisement comprising an indication of a coupling strength between the first micro-PTU-coil and the object; determining that the object is an electronic device; and determining to apply a current to the first micro-PTU-coil using the location of the electronic device and the coupling strength data.
