Abstract
Systems, apparatuses, and methods are described for presence detection of a wireless device in a sensing region. Communication parameters determined by a computing device over one or more periods may be used to generate criteria for determining the occurrence of enter events or leave events. The criteria may comprise, for values of one or more communication parameters, rates of change associated with movement into or out of the sensing region. The criteria may be compared against subsequent data associated with the communication parameters to determine if an enter event or a leave event has occurred.
Claims48
A method comprising:
- determining, by a computing device, one or more rates of change of values of a parameter for wireless communications associated with a wireless device;
- determining, based on receiving an indication that the wireless device has disconnected from the computing device and based on the one or more rates of change, whether the wireless device left a premises associated with the computing device;
- and
- causing, based on whether the wireless device left the premises, sending of a message indicating whether the wireless device left the premises.
A computing device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the computing device to:
- determine one or more rates of change of values of a parameter for wireless communications associated with a wireless device;
- determine, based on receipt of an indication that the wireless device has disconnected from the computing device and based on the one or more rates of change, whether the wireless device left a premises associated with the computing device;
- and
- cause, based on whether the wireless device left the premises, sending of a message indicating whether the wireless device left the premises.
A non-transitory, computer-readable medium storing instructions that, when executed by a computing device, cause:
- determining one or more rates of change of values of a parameter for wireless communications associated with a wireless device;
- determining, based on receiving an indication that the wireless device has disconnected from the computing device and based on the one or more rates of change, whether the wireless device left a premises associated with the computing device;
- and
- causing, based on whether the wireless device left the premises, sending of a message indicating whether the wireless device left the premises.
