Upper layer device architecture for ultra-wide band enabled device

A smart ultra-wide band (UWB) enabled device, the device including:

• a UWB communication port;
• an out-of-band (OOB) communication port;
• memory to store multiple UWB enabled applications and service profile information for the multiple UWB enabled applications;
• and
• an application processor configured to:
• establish a secure OOB communication channel with a separate device and register the service profile information with the separate device using the secure OOB communication channel;
• establish a secure UWB communication channel with the separate device and transfer ranging information to the separate device using the secure UWB communication channel when a first UWB enabled application communicates with the separate device and the service profile information of the first UWB enabled application indicates the first UWB enabled application uses secure ranging;
• and
• establish an unsecured communication channel with the separate device and transfer ranging information to the separate device using the unsecured communication channel when a second UWB enabled application communicates with the separate device and the service profile information of the second UWB enabled application indicates the first UWB enabled application uses unsecured ranging.

A non-transitory machine-readable storage medium including instructions that, when performed using an application processor of a smart ultra-wide band (UWB) enabled device, cause the smart UWB enabled device to perform acts comprising:

• establishing a secure out-of-band (OOB) communication channel with a reader device;
• registering service profile information of multiple UWB enabled applications of the smart UWB capable device with the reader device using the secure OOB communication channel;
• establishing a secure UWB communication channel between the smart UWB capable device and the reader device;
• transferring ranging information to the reader device using the secure UWB communication channel for a first UWB enabled application when the registered service-profile information indicates the first UWB enabled application uses secure ranging;
• and
• transferring ranging information from a second UWB enabled application to the reader device using an unsecured communication channel when the registered service-profile information indicates the second UWB enabled application uses unsecured ranging.
