Systems and methods for inventory round slot classification are described. The method includes transmitting, to zero or more RFID tags, a message during a slot of an inventory round and receiving a response from at least some of the zero or more RFID tags. The method also includes analyzing a received response for the presence of the pilot tone and classifying a respective slot in response to the analysis.

Each of multiple radio devices in a region (e.g., a zone) receives time reference information for synchronizing themselves amongst each other. For example, based on the timing reference information, each radio device in a region synchronizes itself with respect to a common time reference, enabling communications according to shared access schedule (e.g., a time slotted access schedule). Each of the radio devices schedules communications to one or more target devices (e.g., RFID tags) in a monitored region based at least in part according to the shared access schedule. For example, each of multiple transmitters of the tag readers are assigned one or more time slots of the shared access schedule in which they are permitted to communicate in the monitored region.

The present disclosure is directed to methods and systems for a modular, configurable radio frequency identification (RFID) system receiving RFID communications and packaged in a casing for incorporation into a host object. The RFID system may interact with other systems based on the received RFID communications, and may include an antenna. An RFID receiver may receive RFID communications from an RFID tag via the antenna. A memory element may store a configuration for the system, which may be specific to a context of the host object and specify interactions with a second system in response to the received RFID communications. A processor may retrieve from the memory element the configuration responsive to receiving the RFID communications. A transmitter may transmit, via a second communications protocol, a request to the second system based on the interactions specified by the retrieved configuration.

A multi-modal entity tracking and display system is disclosed. In one embodiment, a tracking infrastructure comprising at least one data receiver is configured to detect a tracked entity comprising a first asset class using a first sensing technology and a second sensing technology. The at least one tracking data receiver is further configured to generate a tracking data report conveying a location of the tracked entity. A multi-modal entity tracker is configured to receive and store the tracking data report. The multi-modal entity tracker is further configured to receive and store a second tracking data report of a second tracked entity comprising a second asset class which is conveyed via the tracking infrastructure.
