The fifth Generation mobile communication technology (5th-Generation, 5G) can provide higher communication speed, lower latency, and a larger number of simultaneous connections than the previous Generation technologies. Millimeter wave communication technology with frequency band above 20GHz is one of the key technologies in 5G technology because of its very wide communication bandwidth. In general, the millimeter wave band is divided into 5G bands, and therefore, in the future, various electronic products, particularly mobile communication terminals such as mobile phones, equipped with a millimeter wave antenna module will be increasing.
The user terminal Equipment (CPE) may convert the mobile network signal into a wireless network signal and then connect the wireless network signal to a mobile terminal such as a mobile phone of a user. The space link loss of 5G millimeter wave communication is large, and the power consumption and the heat generation of the mobile terminal are high, so that the 5G millimeter wave network signal can be converted into a wireless network signal and provided for CPE used by a plurality of users, and the practicability is very high.
However, the millimeter wave communication technology and 5G millimeter wave CPE of the current mobile terminal have the following defects:
in order to ensure certain millimeter wave communication quality, more than 2 millimeter wave communication modules are required to be installed at different positions on the mobile terminal. However, due to the limitations of the internal space of mobile terminals such as mobile phones and the like and the influence of the shell material of the mobile terminal on the millimeter wave antenna, the space and the position for installing the millimeter wave communication module in the mobile terminal are very limited, which has a great influence on the communication quality;
the power consumption and the heat productivity of the millimeter wave communication system are very high, so that the battery power consumption of mobile terminals such as mobile phones is high, and the heat dissipation effect inside the terminals is poor;
the mobility of the mobile terminal and the influence of surrounding human bodies and objects can cause the communication quality of millimeter wave communication to be low, and meanwhile, because the mobile terminal needs to continuously scan beams again to search the direction of the base station, the power consumption and the heat productivity of the system are increased;
the current 5G millimeter wave CPE is large in size and needs to be fixedly placed for use. Because the communication range of the wireless network is relatively small, after a user leaves the wireless network communication range of the CPE, the user cannot be connected to the CPE to carry out 5G millimeter wave high-speed communication, and the communication experience of the user is influenced to a great extent.
