Abstract
A system includes a host device having a hardware processor and a host wireless transceiver, and client devices having client wireless transceivers for wireless communications with the host device. The hardware processor receives wireless signals transmitted by the client wireless transceivers using the host wireless transceiver, and determines locations of the client devices relative to the host device based on angles of arrival of the of the wireless signals. The hardware processor further determines an activation sequence for activating the client devices based on the locations relative to the host device, and transmits control signals using the host wireless transceiver, according to the activation sequence, to activate the client devices.
