Abstract

Claims (35)

1 . A method comprising:

authenticating, by an access control system, a first credential of a first mobile device over a first Bluetooth communication connection established between the first mobile device and the access control system;

authenticating, by the access control system, a second credential of a second mobile device over a second Bluetooth communication connection established between the second mobile device and the access control system;

receiving, via a reader of the access control system during an ultra-wideband (UWB) ranging session between the first mobile device and the reader, first UWB data indicative of a location of the first mobile device relative to the reader;

receiving, via the reader during a UWB ranging session between the second mobile device and the reader, second UWB data indicative of a location of the second mobile device relative to the reader;

determining, by the access control system, whether a user of the first mobile device intends to access an asset secured by the access control system based on the first UWB data and satisfying a first set of one or more intent criteria associated with a first mode of entry;

determining, by the access control system, whether a user of the second mobile device intends to access the asset based on the second UWB data and satisfying 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

performing, by the access control system, a predefined function in response to determining that at least one of the user of the first mobile device or the user of the second mobile device intends to access the asset.

2 . The method of claim 1 , wherein determining that the first set of one or more intent criteria has been satisfied comprises determining that the first mobile device is located within a predefined threshold distance relative to the reader.

3 . The method of claim 1 , wherein determining that the first set of one or more intent criteria has been satisfied comprises determining that the first mobile device is located within a predefined region.

4 . The method of claim 1 , wherein determining that the first set of one or more intent criteria has been satisfied comprises determining that the user of the first mobile device has performed a predefined interaction with the access control system.

5 . The method of claim 1 , wherein determining that the first set of one or more intent criteria has been satisfied comprises determining that the user of the first mobile device is located within a predefined threshold distance relative to the reader for a threshold period of time.

6 . The method of claim 1 , wherein determining that the first set of one or more intent criteria has been satisfied comprises determining that a trajectory and speed of the first mobile device are indicative of an intent of the user of the first mobile device to access the asset.

7 . The method of claim 1 , wherein determining whether the first set of one or more intent criteria has been satisfied comprises determining that the first mobile device is within a predefined threshold distance or region relative to the reader and determining whether the user of the first mobile device has interacted with the first mobile device.

8 . The method of claim 1 , wherein performing the predefined function comprises unlocking a lock mechanism of the access control system.

9 . The method of claim 1 , further comprising initiating the UWB ranging session between the firs mobile device and the reader in response to successful authentication of the first credential over the first Bluetooth communication connection.

10 . An access control system comprising:

a lock mechanism configured to secure access to an asset;

a reader configured for ultra-wideband (UWB) communication;

a processor; and

a memory comprising instructions stored thereon that, when executed by the processor, cause the access control system 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 system;

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 system;

receive, via the reader during a UWB ranging session between the first mobile device and the access control system, first UWB data indicative of a location of the first mobile device relative to the reader;

receive, via the reader during a UWB ranging session between the second mobile device and the access control system, second UWB data indicative of a location of the second mobile device relative to the reader;

determine whether a user of the first mobile device intends to access the asset 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 asset secured by the lock mechanism 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 at least one of the user of the first mobile device or the user of the second mobile device intends to access the asset.

11 . The access control system of claim 10 , wherein to determine that the first set of one or more intent criteria has been satisfied comprises to determine that the first mobile device is located within a predefined threshold distance relative to the reader.

12 . The access control system of claim 10 , wherein to determine that the first set of one or more intent criteria has been satisfied comprises to determine that the first mobile device is located within a predefined region.

13 . The access control system of claim 10 , wherein to determine that the first set of one or more intent criteria has been satisfied comprises to determine that the user of the first mobile device has performed a predefined interaction with the access control system.

14 . The access control system of claim 10 , wherein to determine that the first set of one or more intent criteria has been satisfied comprises to determine that the user of the first mobile device is located within a predefined threshold distance relative to the reader for a threshold period of time.

15 . The access control system of claim 10 , wherein to determine that the first set of one or more intent criteria has been satisfied comprises to determine that a trajectory and speed of the first mobile device are indicative of an intent of the user of the first mobile device to access the asset.

16 . The access control system of claim 10 , wherein to determine whether the first set of one or more intent criteria has been satisfied comprises to determine that the first mobile device is within a predefined threshold distance or region relative to the reader and to determine whether the user of the first mobile device has interacted with the first mobile device.

17 . The access control system of claim 10 , wherein the reader comprises a network interface device comprising a plurality of antennas.
