Ultra-wideband technologies for seamless access control

A system, comprising:

• an access control device configured to control access to a passageway;
• a first computing device associated with the access control device, the first computing device comprising a first Bluetooth Low Energy (BLE) communication circuitry and a first ultra-wideband (UWB) communication circuitry;
• and
• a second computing device comprising a second BLE communication circuitry and a second UWB circuitry;
• wherein the first computing device is configured to communicate with the second computing device over a BLE communication connection established between the first computing device and the second computing device to determine that the second computing device is capable of UWB-based communication;
• wherein the second computing device is configured to wake the second UWB communication circuitry from a low power state in response to the BLE communication;
• wherein the first computing device is further configured to determine a location of the second computing device relative to the first computing device based on at least one UWB communication signal received from the second computing device;
• wherein the first computing device is further configured to determine 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
• wherein the first computing device is further configured to direct a user of the second computing device, via an interface of the second computing device, to an exit of the building based on the location of the second computing device within the building.

A first computing device, comprising:

• a Bluetooth Low Energy (BLE) communication circuitry;
• an ultra-wideband (UWB) communication circuitry;
• a processor;
• and
• a memory comprising a plurality of instructions stored thereon that, in response to execution by the processor, causes the first computing device to:
• communicate with a second computing device over a BLE communication connection established between the first computing device and the second computing device to determine that the second computing device is capable of UWB-based communication;
• determine a location of the second computing device relative to the first computing device based on at least one UWB communication signal received from the second computing device in response to UWB communication circuitry of the second computing device being awaken based on the BLE communication with the first computing device;
• determine 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
• direct a user of the second computing device, via an interface of the second computing device, to an exit of the building based on the location of the second computing device within the building.
