Description

technical field [0001] The present invention relates to the communication field, in particular to a data card temperature control method and device. Background technique [0002] With the development of mobile communications and the continuous evolution of 3G technology, the transmission rate of wireless data card terminals is getting higher and higher, and the size of terminals is getting smaller and smaller. Therefore, heating of data cards has become a significant problem. Generally, after a period of use, the data card is easy to generate heat, and some wireless data cards may even be hot to the hand, which not only easily causes aging and damage of the device, but also may burn the user or cause a fire. [0003] For this problem, there are currently two main solutions: optimizing the external design of the data card and reducing the transmission power of the wireless terminal. Optimizing the external design of the data card is to select materials with good heat dissipa...

AI Technical Summary

Problems solved by technology

Optimizing the external design of the data card is to select materials with good heat dissipation and optimize the shape and structure of the data card, such as punching holes or opening slots in the metal material to increase the heat dissipation area, but this cannot fundamentally solve the problem of heat generation of the data card, and also It will increase the cost; the scheme of reducing the transmission power of the wireless terminal considers that the heating of the wireless terminal mainly comes from the power amplifier, and the heating of the power amplifier is related to the uplink transmission power, so when the temperature reaches a certain threshold value, the transmission power is reduced to control the device When the temperature still rises and reaches the emergency threshold, the transmitter will be turned off directly. When the temperature drops to a certain threshold, the transmission power will be gradually increased to the normal value. However, this solution has the disadvantage that it may appear under weak signal The network is dropped due to the reduction of transmission power, which affects the user experience

[0004] In short, none of the existing technologies can solve the problem of heat generation of data cards well.
