Abstract
Methods, systems, and devices for wireless communication are described. The reader may send a trigger message that initiates an inventory procedure for identifying wireless devices within the coverage of the reader (2005). In response to receiving the trigger message, each wireless device may transmit a waveform that includes an application layer identifier of the wireless device (2010) that may uniquely identify the wireless device. The source device may send a message responsive to the waveform indicating application of the layer identifier, and a layer-one identifier (2015), where the layer-one identifier may be used for subsequent communications between the reader and the wireless device. The checking process can be a two-step process or a four-step process.
