Abstract
An ultra-wide band (UWB) device including a memory configured to store one or more instructions, a communications part configured to perform UWB communications with a mobile device, one or more processors configured to execute the one or more instructions to perform a ranging together with the mobile device on basis of a reception window, counts a standby counter wherein when the ranging fails, and enter a sleep mode when the standby counter is equal to or greater than a maximum standby count.
Claims9
An ultra-wide band (UWB) device, comprising:
- a memory configured to store one or more instructions;
- a communications part configured to perform UWB communications with a mobile device;
- one or more processors configured to execute the one or more instructions stored in the memory, thereby configuring the one or more processors to:
- perform a ranging together with the mobile device based on a reception window,
- count a standby counter when the ranging fails;
- clear the standby counter when the ranging succeeds;
- and
- enter a sleep mode when the standby counter is equal to or greater than a maximum standby count.
A control method for controlling an ultra-wide band (UWB) device, the control method comprising:
- performing, by a processor, a ranging together with a mobile device based on a reception window;
- counting, by the processor, a standby counter when the ranging performed by the processor fails;
- clearing, by the processor, the standby counter when the ranging performed by the processor succeeds;
- and
- comparing, by the processor, the standby counter with a maximum standby count, and repeating the ranging or entering a sleep mode.
