Description

Customer premises equipment

Technical Field

The application relates to the technical field of electronics, in particular to customer premises equipment.

Background

A CPE (Customer Premise Equipment) is a mobile signal access device that receives a mobile signal and forwards the mobile signal as a wireless Wi-Fi signal, and is also a device that converts a high-speed 4G or 5G signal into a Wi-Fi signal, and the number of mobile terminals capable of accessing the internet at the same time is also large. The CPE can be widely applied to wireless network access in rural areas, towns, hospitals, units, factories, cells and the like, and the cost for laying a wire network can be saved.

When the distance is relatively long or there are many obstacles, signal blind spots are likely to occur in the coverage of the base station signal. In these blind spot corners, the terminal device, such as a smartphone, cannot receive the base station signal. The CPE can relay the base station signals for the second time, and the base station signals are changed into Wi-Fi signals to be provided for the equipment nearby. Compared with terminal equipment such as a smart phone and a notebook computer, the CPE antenna has the advantages of stronger gain, higher power and stronger signal transceiving capacity. So, there are places where the smartphone has no signal and the CPE may have a signal. The CPE can change network signals of an operator into Wi-Fi signals, and more devices such as a smart phone, an ipad and a notebook computer can surf the internet by means of the CPE.

The CPE has a limited internal space and there is often a certain requirement on the volume of the CPE in order to improve its portability. However, the volume of the CPE is limited, which affects the space inside the CPE where the antenna is installed, and thus the performance of the CPE.
