Abstract
Systems and methods for low power wireless device detection are provided. In one or more implementations, a transmitting/advertising device may include a device identifier and/or one or more time-offset bits in a wireless communication frame for a scanning/receiving device. The scanning/receiving device may perform sequence-level correlation operations to detect the presence of the transmitting/advertising device. The sequence-level correlation operations may detect the transmitting/advertising device based on a detection of a correlation signal peak corresponding to the device identifier, and/or based relative timing of the correlation signal peak corresponding to the device identifier and a correlation signal peak corresponding to another item in the wireless communication frame.
