20 Claims

1. A method, comprising:

communicating, via a Bluetooth communication circuitry of a first computing device associated with an access control device that controls access to a passageway, with a second computing device over a Bluetooth communication connection established between the first computing device and the second computing device to determine that the second computing device includes ultra-wideband (UWB) communication circuitry for UWB-based communication;

waking the UWB communication circuitry of the second computing device from a low power state in response to the Bluetooth communication;

determining, by the first computing device based on at least one UWB communication signal received from the second computing device, a location of the second computing device relative to the first computing device;

determining a location of the second computing device within a building based on the location of the second computing device relative to the first computing device; and

directing, via an interface of the second computing device, a user of the second computing device to an exit of the building based on the location of the second computing device within the building.
