The router is now an indispensable product in modern life. More antennas does not mean better signal. It mainly depends on the performance of the product, that is, how well the wall is penetrated. The better.

The number of antennas is related to MIMO technology. Multiple antennas and wireless terminals transmit data at the same time, and the corresponding transmission rate is multiplied by the wireless rate of a single channel; taking MIMO 2 * 2 technology as an example, just like two people working at the same time, the original work efficiency Increased by two times, increased the wireless rate and improved the communication quality. Before choosing a router with a few antennas, we must first understand the difference between the first, second, and third antennas of the wireless router? For 2.4G frequency band, 40MHz channel bandwidth, one antenna 150Mbps, two antennas 300Mbps, three antennas 450Mbps, and so on; for 5G frequency band, 160MHz channel bandwidth, one antenna 433Mbps, two antennas 867Mbps, three antennas 1.2Gbps , And so on; there are also 2.4G and 5G multiplexed antennas, that is, two antennas support both 2.4G and 5G bands, and the dual-band concurrent rate is 300Mbps + 867Mbps = 1167Mbps

If it is not the rule, it can only mean that the router uses the "built-in antenna" or "fake antenna". If you want to overturn the number of antennas, the better the router, the better. The first thing we need to make clear is that the coverage of the wireless router is determined by the 802.11 protocol, and the signal strength and wall penetration ability we usually say are received WiFi signal transmission power. When we evaluate the quality of a router, we are judging from the coverage, signal strength, and wall-penetrating ability, but obviously these three points are not related to the number of router antennas.

The quality of So, 4g router with external antenna is not determined by the number of antennas, mainly depends on the stability of the router itself.
