1. The concept of 5G
5G, in the field of wireless networks, actually has two meanings, one refers to the 5GHZ (5 billion times per second vibration rate) frequency wifi in the wifi signal, and the other refers to the 5th generation communication signal in the mobile network, so Before you buy it, novices should figure out when 5G is 5G. Is this 5G 5G as you understand it?
2. The universality of 5GHZ wifi
5Ghz wifi is now standard. Two chips can be put in a router to correspond to different wifi signals (2.4G+5G). This 5Ghz signal has fast frequency and large capacity, and is generally better than 2.4G signals. use;
Mobile 5G router
If you see a 5G router, it is a real 5th generation mobile network signal router, then your thoughts are as follows:
Insert the card: The sim card is definitely needed now;
Mobile: If you want to carry it with you, whether the power supply can be equipped as standard (voltage level, current level);
5G signal mode: is it dual-mode or single-mode? Dual-mode has great advantages. Single-mode can only increase the download speed in the 5G signal coverage area. For game enthusiasts, the low latency is still similar to 4G;
Signal coverage: Although 5G commercial use has long been out, but the national market has led to a certain period of time for national coverage, and 4G is the priority;
