As early as the 3G era, a peripheral called mobile Wi-Fi appeared around us. Inserting a SIM card can share the 3G network with other nearby mobile phones or laptops. With the popularization of 5G networks, a 5G CPE that sounds taller is coming to the fore.

In fact, the mobile 5G Wi-Fi and 5G mobile routers that we often talk about are essentially 5G CPE (Customer Premise Equipment), which belong to a kind of mobile network that can receive mobile network signals and transmit them to Wi-Fi. -Fi signal forwarding for shared devices.

Among various network devices, CPE is actually very similar to an optical modem with its own router function. The difference between them is that the optical cat is connected to the home optical fiber from the operator, and then converted into a Wi-Fi signal or a wired signal (need to connect to the LAN port), allowing more local devices (such as mobile phones, tablets, computers, smart phones, etc.) home) Internet access. However, most optical modems have weak routing functions, so many families will purchase additional Wi-Fi 6 routers to connect to optical modems to further improve network speed, signal strength (wall penetration capability) and coverage.

5G CPE receives 5G wireless signals from nearby operator base station towers (4G CPE if only 4G networks are supported, 5G is backward compatible with 4G and 3G) and converts them into Wi-Fi signals for more local The device is connected to the Internet. Of course, if the 5G CPE router itself is equipped with a LAN port, it can also be used to connect to other routers or provide wired Internet access for computers.
