1. A method of transferring wireless energy via near-field magnetic coupling from a transmitting base to one or more electronic devices configured to receive the wireless energy, wherein the wireless energy comprises one of wireless electrical energy, data, or combinations thereof, and wherein the transmitting base includes, a housing comprising a first sidewall positioned at a base proximal end, a second sidewall positioned at a base distal end, and a third sidewall that intersects with each of the first and second sidewalls, the method comprising:
transmitting the wireless energy via at least one transmitting coil, wherein the at least one transmitting coil is positioned above and substantially parallel to an interior of the first sidewall of the housing such that a gap extends between the at least one transmitting coil and the interior of the first sidewall and the at least one transmitting coil is in physical contact with at least an interior of the third sidewall, and wherein the at least one transmitting coil is configured to resonate at a transmitting coil resonant frequency or a transmitting coil resonant frequency band;
re-transmitting the wireless energy via at least one repeater coil, wherein the at least one repeater coil is positioned along the interior of the third sidewall of the housing and spaced apart from the at least one transmitting coil, the at least one repeater coil configured to receive the wireless energy from the at least one transmitting coil and re-transmit the received wireless energy, and wherein each of the one or more electronic devices comprises at least a receiving coil configured to receive at least the re-transmitted wireless energy; and
receiving the re-transmitted wireless energy by the receiving coil of each of the one or more electronic devices from the at least one repeater coil.
