Abstract
An IoT device having a low power consumption mode and an operating method thereof are disclosed. An objective in accordance with an aspect of an embodiment is to provide an IoT device wirelessly communicating, without a gateway, with a terminal by only a repeater and an operating method thereof.
Claims12
An IoT device having low power consumption which is directly connected to a repeater without using a gateway and wirelessly communicates with a terminal, the IoT device having low power consumption comprising:
- a control part configured to operate in a repeater mode in a situation that a preset condition is satisfied, configured to operate in a terminal mode and try to access to the repeater corresponding to repeater information in a situation that a mode change signal and the repeater information are received in a preset time, and configured to operate in a sleep mode in a situation that the mode change signal and the repeater information are not received in the preset time, wherein beacons are transmitted in the repeater mode, and at least a part of the IoT device is not provided with power in the sleep mode;
- a wireless communication part configured to transmit, according to control of the control part, the beacons or a signal for accessing to the repeater corresponding to the repeater information, or configured to receive the mode change signal or the repeater information from the terminal;
- and
- a power supply part configured to provide the power using a battery.
An operating method of an IoT device having low power consumption which is directly connected to a repeater without a gateway and wirelessly communicates with the terminal, the operating method of the IoT device having low power consumption comprising:
- in a transmitting process, operating in a repeater mode in a situation that a preset condition is satisfied, wherein beacons are transmitted in the repeater mode;
- in a determining process, determining whether a mode change signal and a repeater information are received in a preset time;
- in an accessing process, operating in a terminal mode to try to access to the repeater corresponding to repeater information in a situation that the mode change signal and the repeater information are received in the preset time;
- and
- in a turning-off process, operating in a sleep mode to in a situation that the mode change signal and the repeater information are not received in the preset time, wherein in the sleep mode, at least a part of the IoT device is not provided with power.
