Abstract: A system that performs self-calibration for tracking packages includes a frame providing storage locations for storing items, radio frequency identification (RFID) tags disposed in the storage locations, and an RFID antenna(s). The system determines a distance between each RFID tag and the RFID antenna(s) and monitors signal characteristics from each RFID tag. For each RFID tag, the system generates (i) at least one first parameter indicative of an environmental condition(s) at a location of the RFID tag and (ii) at least one second parameter indicative of a response rate behavior of the RFID tag, based on the signal characteristics and the distance between the RFID tag and the RFID antenna(s). The system tracks an RFID tagged item located in one of the storage locations based at least in part on the first and second parameter(s) for each of the RFID tags.

Abstract: Disclosed are various embodiments for managing which location-based service zones to monitor when the number location-based service zones within a geographic region exceed the amount the device can support. An active zone defining a geographic region and location-based service zones within the geographic region is provided by another computing device. When the number of location-based service zones meets or exceeds a predefined threshold, a subset of the location-based service zones is selected for monitoring according to a current device location and/or other parameters.

Abstract: Disclosed are various embodiments for managing location-based service zones. Specifically, a dynamically sized geographic region surrounding a client device location can be created. Location-based service zones within the geographic region can be selected. If the amount of location-based service zones identified within the geographic region exceed a client-supported limit, a subset of location-based service zones are selected and sent to the client device for monitoring.
