IPhone X does not support wifi6.
The so-called WiFi 6 is actually the sixth generation standard announced by the Wi-Fi Alliance. The signal of WiFi 6 is mainly transmitted by indoor routers and AP, and the highest rate of WiFi 6 can reach 9.6Gbps, that is to say, the theoretical transmission speed reached 1.2GB\/s, which is several times the previous transmission protocol.
At the same time, WiFi 6 mainly uses OFDMA, MU-MIMO and other technologies, MU-MIMO(multi-user multi-input multi-output) technology allows the router to communicate with multiple devices at the same time, rather than in turn. MU-MIMO allows routers to communicate with four devices at a time, and WiFi 6 will allow communication with up to eight devices. WiFi 6 also makes use of other technologies such as OFDMA(orthogonal frequency division multiple Access) and transmit beamforming, which work to increase efficiency and network capacity, respectively.
The iphone xr supports wifi6. WiFi6 is a wireless network protocol that has been completely overwhelmed by data compared to WiFi5 and WiFi4. With a maximum speed of 9.6Gbps, WiFi6 is designed for the 5G era and optimizes signal uplink coverage, which is perfectly compatible with the NB-IoT Internet of Things.
IPhone EXR does not support wifi6, only Snapdragon 865 processor models plus the use of supporting WiFi6 router, that is, from the iphone11 mobile phone to support wifi6.
