Embodiment Construction

[0026] figure 1 It is a block diagram showing a hardware architecture of a method for controlling transmission signal power of a mobile device according to an embodiment of the present invention. Such as figure 1 As shown in , the electronic system 100 includes a wireless module 102 , a control unit 104 and a storage unit 106 . For example, the electronic system 100 can be a mobile phone, a smart phone, a PDA mobile phone, and / or other devices capable of transmitting signals via an antenna. In one embodiment, the electronic system 100 may be a device for controlling transmission signal power of a mobile device. In some embodiments, the control unit 104 may be internal to the wireless module 102 ; while in other embodiments, the control unit 104 may be external to the wireless module 102 . When the electronic system 100 turns on the wireless module 102 during the boot process, the wireless module 102 first sets the transmission signal power of the wireless module 102 accordi...

Abstract

The invention provides a method and a device of controlling transmission signal power of a mobile device. The method includes the following steps of reading a specific transmission signal power set value from a storage cell outside a wireless module, wherein the specific transmission signal power set value differs from a preset transmission signal power set value stored in a storage inside the wireless module, and setting a transmission signal power of the mobile device according to the specific transmission signal power set value. The method of controlling the transmission signal power of the mobile device enables a designer to store the specific transmission signal power set value in the storage outside the wireless module. Through the above various used embodiments, the transmission signal power of the mobile device can be changed, and so that electromagnetic wave energy absorbed by a user can be reduced and transmission efficiency of signals cannot be influenced.

Description

technical field [0001] The present invention relates to controlling the transmission signal power of a mobile device. Background technique [0002] In the mobile device, the antenna is arranged on the edge of the mobile device to improve the efficiency of signal transmission. When the distance between the antenna and the user decreases, the energy of the electromagnetic wave received by the user will increase. Excessive electromagnetic wave energy will cause harm to the user, so it is necessary to control the amount of electromagnetic wave energy received by the user to avoid harm to the user. [0003] The method of reducing the amount of electromagnetic wave energy received by the user can be by increasing the distance between the user and the antenna, but there is not enough space in a mobile device with a limited size to increase the distance between the user and the antenna. Another method is to use a distance sensor to control the transmission signal power of the wirel...
