This issue needs to be discussed on a case-by-case basis. First of all, the network is a comprehensive project, and the router is only one of the links. To enjoy the data transmission rate of WIFI 6, first of all, your terminal (network card, mobile phone, tablet, etc.) must also support WIFI 6. If you don’t have such a device, don’t rush to upgrade. Of course, it is a trend for new devices to support WiFi6. Even if there is no WiFi6 terminal, you can prepare in advance. Anyway, WiFi6 routing can be backward compatible with WiFi5 and WiFi4.
Secondly, it is difficult for the existing WiFi 6 routing to fully realize the theoretical indicators. What the most fatal point is that the speed of WiFi 6 can reach up to 9.6Gbps under the 8*8 antenna and 160MHz bandwidth, even if it is a shrinking WiFi 6 device theoretically can run to 1.2Gbps, but many WiFi 6 routers are still gigabit ethernet routers. No matter what kind of devices you have or what the network environment your home is, these routers’ highest rate is only 1Gbps, unless it is a real 10Gb router (such as ASUS RT-AX89X). If you only want to buy for the theoretical rate of WIFI 6, you will be disappointed.
Of course, if you only come for the OFDMA function, there is a rigid need to reduce the connection delay of multiple devices, which can be the first choice for upgrading, and now there are many wifi 6 routers in the market, and the upgrade cost is not high.

Is the mu-mimo function necessary?
If you buy a router specifically for the mu-mimo function, it is not necessary for you to do that. Although mu-mimo has been around for a long time, it is still far from mature. It is still a bit harsh to meet the conditions of mu-mimo, and it is still far from being truly practical.
First of all, in order to meet the conditions of mu-mimo, in addition to the router, your receiving device must also support mu-mimo. Secondly, even if your router and mobile device support mu-mimo, mu-mimo also has a limit on the number of channels , if this limit is exceeded or the supported specifications are different, you still cannot enjoy this function. 2*2 mu-mimo cannot meet the actual needs to a large extent. It can be said that as long as the router does not develop to 8*8 mu-mimo , the mu-mimo technology has not yet reached the real practical stage.
Is the radiation of the router harmful to the human body?
Many people’s fear of radiation comes from radioactive substances, but it needs to be clear that the radiation of radioactive substances is ionizing radiation, such as gamma rays, X-rays, ultraviolet rays, etc. Only this type of radiation is what everyone thinks will harm the human body. The radiation of routers belongs to electromagnetic radiation. According to relevant standards, the maximum transmission power of routers will not exceed 100mW, which is lower than the radiation of mobile phones. As long as you buy regular brand routers, you don’t have to worry about radiation problems.
Are more router antennas better?
The answer is no. Many people have such a perception: the more antennas on the router, the better the signal coverage. If you regularly browse some tech review sites, you will knowthat in fact the most direct factor affecting the signal is the transmit power, not the number of antennas. Under the premise of a certain power, increasing the number of antennas can indeed increase the transmission distance of wireless signals to a certain extent, but this improvement is very insignificant. It is impossible for the number of antennas to double and the signal strength to double. Therefore, you do not need to pay too much attention to the number of router antennas when purchasing router.
