Many people go back to their hometown or rent a house temporarily. When it is inconvenient to use broadband, they choose to open a hotspot or use portable WiFi, and 4G routers are ignored by everyone.

To put it simply, a 4G router is actually a mobile phone card + wireless router. An ordinary wireless router is connected to a broadband network, and a 4G router is connected to a 4G network like a mobile phone.

From the perspective of network experience, the relationship between these is: 4G router > portable WiFi > mobile phone hotspot. Mobile hotspots can be accessed in a small number and have a small coverage area, and it is easy to damage the battery; in order to consider the portability of portable WiFi , the transmit power of portable WiFi is generally limited.

4G routers generally use an external power supply, and there are no restrictions on battery life and transmission power. In addition, 4G routers are generally equipped with high-gain external antennas to obtain better and more stable 4G signals. Therefore, its The effect of Internet access is definitely the best, close to the effect of ordinary household fiber optic broadband. Now there are many 4G routers that support power bank power supply, which is a good helper for picnics and camping!

So how to choose a 4G router? The editor lists 5 issues that users are more concerned about below for your reference:

If the use environment is relatively simple and there is no need to penetrate the wall, it is enough to choose a style without an external antenna, and the current built-in antenna signal is also very good.

4. Whether it supports one machine for dual use
