RADIO DEVICES AND COMMUNICATIONS

摘要

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.
