    Abstract: A communication system and an IoT system are provided. The IoT system is applicable to a wireless network system including an access point. The IoT system includes a WiFi module and a GPIO device. The WiFi module is configured to connect to the access point. The GPIO device is configured to provide a plurality of wake-up signals to the WiFi module through a GPIO pin. A predetermined time period between any two of wake-up signals is greater than an interval between two delivery traffic indication messages from the access point. The WiFi module includes a timer and a power management unit, the power management unit drains power to transfer the WiFi module from a sleep mode to a normal mode after the timer receives the wake-up signal.

    Abstract: A method of saving power of a station in wireless network is provided. The station comprises a connectivity module, a central processing unit, and peripheral devices. The method includes: upon receiving a wake-up signal, powering on the connectivity module, the central processing unit, and the peripheral devices; performing the central processing unit and the peripheral devices in a connection state; performing the connectivity module in an authenticated state; and upon a condition that there is no data to be transferred to the station or after the station transmits and receives all needed data, performing a sleep mode to power off the connectivity module, the central processing unit, and the peripheral devices.

    Abstract: A method of changing from a Sleep mode to an Awake mode in a WIFI system includes (a) performing a TIM or DTIM inspection by using an auxiliary application, (b) performing Power-Down when no data to receive exists as a result of the inspection in the operation (a), and (c) changing to the Awake mode by using a main application when data to receive exists as a result of the inspection in the operation (a). According to the method of changing from a Sleep mode to an Awake mode in a WIFI system, power consumption may be minimized by dualizing an application and using an auxiliary application including only essential functions for TIM/DTIM inspection, separately from a main application.
