[0019] CPE (Customer Premise Equipment) is a new type of wireless terminal access device that can receive wireless signals such as wireless routers / wireless APs / wireless base stations. CPE can act as a wired network interface or convert it into Wi-Fi signals to provide device connections in scenarios such as home or office. 5G industrial CPE uses the public 5G network to provide users with wireless long-distance large data transmission capabilities. The 5G CPE host is a 5G terminal device that can receive 5G signals from operator base stations and convert them into Wi-Fi signals or wired signals, allowing more local devices (such as mobile phones, tablets, computers, etc.) to access the Internet. The advantage of the 5G CPE host lies in its mobility and flexibility. Unlike the "optical modem" that is fixed in one place, the 5G CPE can be used anywhere there is a 5G signal. In addition, the 5G CPE host also has powerful 5G access capabilities, supports SA / NSA networking, and is compatible with 4G / 5G signals.
