If the device is authenticated, the wireless signal may be adjusted to provide power to the device. If the device is not authenticated, the wireless signal may be adjusted to avoid providing power to the device. ## Claims ### Claim 1 A method comprising: transmitting, by a computing device, a plurality of wireless signals, wherein each wireless signal is configured to supply power to one or more devices to enable the one or more devices to perform authentication, and wherein each wireless signal is transmitted with a signal identifier associated with the wireless signal; receiving, by the computing device and from at least one of the one or more devices, an indication of the signal identifier associated with one of the plurality of wireless signals; and adjusting, by the computing device and based on the received indication, the wireless signal associated with the indicated signal identifier to provide the at least one of the one or more devices with power for normal operation. ### Claim 2 (depends on 1) The method of claim 1, wherein the wireless signal associated with the indicated signal identifier is spatially adjusted or temporally adjusted. ### Claim 3 (depends on 1) The method of claim 1, wherein the at least one of the one or more devices does not have a dedicated power supply. ### Claim 4 (depends on 1) The method of claim 1, wherein each of the plurality of wireless signals is transmitted into a different region. ### Claim 5 (depends on 1) The method of claim 1, wherein in addition to the indication of the signal identifier of the one of the plurality of wireless signals, the computing device receives a signal strength indicator associated with the one of the plurality of wireless signals. ### Claim 6 (depends on 1) The method of claim 1, wherein the computing device comprises a wireless access point. ### Claim 7 (depends on 6) The method of claim 6, wherein the at least one of the one or more devices is configured to communicate with the wireless access point. ### Claim 8 A non-transitory computer-readable medium storing instructions that, when executed, cause: transmitting a plurality of wireless signals, wherein each wireless signal is configured to supply power to one or more devices to enable the one or more devices to perform authentication, and wherein each wireless signal is transmitted with a signal identifier associated with the wireless signal; receiving, from at least one of the one or more devices, an indication of the signal identifier associated with one of the plurality of wireless signals; and adjusting, based on the received indication, the wireless signal associated with the indicated signal identifier to provide the one of the one or more devices with power for normal operation. ### Claim 9 (depends on 8) The non-transitory computer-readable medium of claim 8, wherein the wireless signal associated with the indicated signal identifier is spatially adjusted or temporally adjusted. ### Claim 10 (depends on 8) The non-transitory computer-readable medium of claim 8, wherein the at least one of the one or more devices does not have a dedicated power supply. ### Claim 11 (depends on 8) The non-transitory computer-readable medium of claim 8, wherein the instructions that, when executed, cause the transmitting the plurality of wireless signals, cause each of the plurality of wireless signals to be transmitted into a different region. ### Claim 12 (depends on 8) The non-transitory computer-readable medium of claim 8, wherein the instructions, when executed, further cause, in addition to the receiving the indication of the signal identifier associated with the one of the plurality of wireless signals, receiving a signal strength indicator associated with the one of the plurality of wireless signals. ### Claim 13 A system comprising: at least one device configured to determine a signal strength associated with wireless signals received by the at least one device; and a computing device configured to: transmit a plurality of wireless signals, wherein each wireless signal is configured to supply power to the at least one device to enable the at least one device to perform authentication, and wherein each wireless signal is transmitted with a signal identifier associated with the wireless signal; receive, from the at least one device, an indication of the signal identifier associated with one of the plurality of wireless signals determined by the at least one device to have a strongest signal strength; and adjust supply, based on the received indication, the wireless signal associated with the indicated signal identifier to provide the at least one device with power for normal operation. ### Claim 14 (depends on 13) The system of claim 13, wherein the wireless signal associated with the indicated signal identifier is spatially adjusted or temporally adjusted. ### Claim 15 (depends on 13) The system of claim 13, wherein the at least one device does not have a dedicated power supply. ### Claim 16 (depends on 13) The system of claim 13, wherein the computing device is further configured to transmit each of the plurality of wireless signals into a different region. ### Claim 17 (depends on 13) The system of claim 13, wherein in addition to the indication of the signal identifier associated with the one of the plurality of wireless signals, the computing device receives a signal strength indicator, determined by the at least one device, associated with the one of the plurality of wireless signals. ### Claim 18 (depends on 13) The system of claim 13, wherein the computing device comprises a wireless access point. ### Claim 19 (depends on 18) The system of claim 18, wherein the at least one device is configured to communicate with the wireless access point.
