Method for WiFi module and system of the same

A method for a WiFi module, comprising:

• determining whether a specific process is a high-power consumption event;
• when the specific process is determined as the high-power consumption event, estimating a first power consumption request information for performing the specific process and transmitting the first power consumption request information to a control module;
• receiving a first response from the control module, wherein the first response corresponds to the first power consumption request information;
• dividing, by the WiFi module, the specific process into a first sub-process and a second sub-process according to the first response;
• and
• performing a time-divisional operation upon the specific process, comprising:
• performing the first sub-process of the specific process;
• and
• after completion of the first sub-process, waiting for a predetermined interval period and then performing the second sub-process of the specific process, wherein a duration of the predetermined interval period is adjusted depending on an upper limit of a power consumption allocated to the WiFi module.
