Mobile device, method and machine-readable storage medium for adjusting radio power

By integrating detectors and processors in mobile devices, and adjusting the output power of the radio frequency module and antenna according to the distance between the user and the device, the impact of electromagnetic waves from mobile devices on the user's health is solved, and the miniaturization and cost of the device are achieved without affecting the equipment. The specific absorption ratio is reduced to ensure the quality of signal transmission.

Problems solved by technology

However, increasing the size of circuit boards contradicts the trend of miniaturization of mobile devices
In addition, reducing the output power will cause the signal transmitted by the antenna to attenuate
Similarly, using microwave absorbing material to change the electric field intensity distribution of the mobile device will also attenuate the signal transmission of the antenna of the mobile device
In addition, the use of high-cost microwave absorbing materials will also increase the cost of mobile devices

Abstract

A mobile device camping on a radio access network is provided. The mobile device includes an antenna, a radio frequency module, a detector and a processor. The RF module transmits a data packet to the radio access network via the antenna according to a radio power. The detector detects a distance between the mobile device and a user, and generates a detection signal according to the distance between the mobile device and the user. The processor controls the antenna and the RF module to transmit a first power level of the radio power to the radio access network according to the detection signal, so as to obtain a second power level from the radio access network, wherein the processor adjusts the radio power according to the second power level. In the invention, the power can be adjusted to reduce the special adsorption ratio of the mobile device.

Description

technical field [0001] The present invention relates to a mobile device, a method for adjusting radio transmission power and a computer program product, and in particular to a mobile device that can detect the distance between a user and the mobile device to adjust the output power to reduce the Specific Absorption Rate (SAR) . Background technique [0002] With the development of wireless communication technology, mobile devices are becoming more and more popular. In the third-generation mobile communication technology, the Wideband Code Division Multiple Access (WCDMA) system can provide circuit-switched (CS) services and packet-switched (PS) services to deal with The transmission and reception of voice and data make the applications of mobile devices more diverse. However, in recent years, studies have found that the electromagnetic waves emitted by mobile devices (such as mobile phones) during use will cause invisible harm to users themselves. Generally speaking, mobi...
