    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: Upon receiving an indication that a customer is initiating travel to a merchant location to pick up one or more items, sensor data may be obtained by, and received from, a customer device of the customer. After the customer has arrived at the merchant location, the customer may be greeted or otherwise interacted with and a corresponding interaction time may be determined. The service provider may identify one or more stop events based on the sensor data, where a stop event indicates that a customer stopped while in transit to the merchant location. A most recent stop event prior to the interaction time may constitute the customer arriving/stopping at the merchant location, and a corresponding arrival time may be estimated. A wait time of the customer may be determined based on a difference between the interaction time and the arrival time.

    Abstract: A customer offset may be determined with respect to a customer who has previously traveled to one or more merchant locations. A merchant location offset may be determined with respect to multiple customers who have each traveled to a particular merchant location. Upon determining that the customer is in transit to the merchant location, a generic ETA to the merchant location may be determined. A customer-based ETA for the customer with respect to the merchant location may be determined based on the generic ETA and the customer offset. Moreover, a merchant location-based ETA for the customer with respect to the merchant location may be determined based on the generic ETA and the merchant location offset. Based on the refined and more accurate ETAs, the merchant location may be instructed to begin assembling items for pick-up by the customer.
