UWB-based modes of entry

An access control device, comprising:

• a lock mechanism configured to secure access to a passageway;
• an ultra-wideband (UWB) subsystem;
• a processor;
• and
• a memory comprising a plurality of instructions stored thereon that, in response to execution by the processor, causes the access control device to:
• authenticate a first credential of a first mobile device over a first Bluetooth communication connection established between the first mobile device and the access control device;
• authenticate a second credential of a second mobile device over a second Bluetooth communication connection established between the second mobile device and the access control device;
• receive, with the UWB subsystem during a UWB ranging session between the first mobile device and the access control device, first UWB data indicative of a location of the first mobile device relative to the access control device;
• receive, with the UWB subsystem during a UWB ranging session between the second mobile device and the access control device, second UWB data indicative of a location of the second mobile device relative to the access control device;
• determine whether a user of the first mobile device intends to access the passageway secured by the lock mechanism based on the first UWB data and satisfaction of a first set of one or more intent criteria associated with a first mode of entry;
• determine whether a user of the second mobile device intends to access the passageway based on the second UWB data and satisfaction of a second set of one or more intent criteria associated with a second mode of entry, wherein the second set is different from the first set;
• and
• unlock the lock mechanism in response to a determination that the user of the first mobile device or the user of the second mobile device intends to access the passageway.
