[0054] figure 2 The first embodiment provided by the present invention is a method for processing electromagnetic wave energy absorption ratio, including:

[0055] S1, detecting the distance between the mobile terminal and the user.

[0056] In this step, the mobile terminal needs to detect the communication signal strength of the base station before detecting the distance from the user, and then determine the optimal transmit power value of the mobile terminal in response to the communication signal strength of the base station, and use the optimal The transmit power value is the maximum power value. Pre-detecting the communication signal strength of the base station, according to the communication signal strength of the base station, is to determine the optimal transmission power value for communication between the mobile terminal and the base station, and use the optimal transmission power value to the maximum transmission power value for signal transmission. The optimal...

Abstract

The invention belongs to the technical field of communication and electronics, and discloses a method and device for processing an electromagnetic wave energy absorption ratio. The processing method comprises the following steps of: detecting the distance between a mobile terminal and a user, alternatively adjusting the transmitting power value of the mobile terminal into a first target power value or a second target power value by taking pre-set duration as an adjustment period when the distance between the user and the mobile terminal is less than or equal to a pre-set distance value, and adjusting the transmitting power value of the mobile terminal to a third target power value when the distance between the user and the mobile terminal is greater than the pre-set distance value. According to the method and the device disclosed by the invention, when the condition that the distance between the user and the mobile terminal is less than the pre-set distance value is detected, the signal transmitting power value of the mobile terminal is returned to the pre-set transmitting power value; then, the signal transmitting power of the mobile terminal is returned or recovered in a pre-set time division manner; and the electromagnetic wave energy absorption ratio is reduced while the mobile communication quality is ensured.

Description

technical field [0001] The invention belongs to the technical fields of communication and electronics, and in particular relates to a processing method and a processing device for electromagnetic wave energy absorption ratio. Background technique [0002] Mobile terminals (such as mobile phones and tablet computers) have become indispensable communication tools. At the same time, the radiation of the mobile terminal's transmission power to the human body has also been valued by various countries and organizations. SAR (Specific Absorption Rate, electromagnetic wave absorption ratio) refers to the electromagnetic wave energy absorption ratio of the mobile terminal, which is the electromagnetic power absorbed or consumed by a unit mass of human tissue, and the unit is W / kg, or mW / mg. The SAR requirements under FCC certification are extremely high. For example, when the diagonal size of the tablet computer is greater than 8 inches, the SAR value of the other 5 surfaces except t...
