What does the number 6 on wifi mean?

The 6 above wifi refers to wifi6, which means the sixth generation wireless network technology. It is a wireless LAN technology created by the Wi-Fi Alliance based on the IEEE 802.11 standard. WiFi6 is a wireless network protocol that mainly uses OFDMA, MU-MIMO and other technologies; Wi-Fi6 will allow communication with up to 8 devices, with a maximum rate of 9.6Gbps.

The 6 above wifi refers to wifi6, which means the sixth generation wireless network technology.

Wi-Fi 6 (original name: IEEE 802.11.ax) is the sixth generation wireless network technology and is the name of the Wi-Fi standard. It is a wireless LAN technology created by the Wi-Fi Alliance based on the IEEE 802.11 standard. Wi-Fi 6 will allow communication with up to 8 devices at a maximum rate of 9.6Gbps.

WiFi6 is a wireless network protocol. Compared with WiFi5 and WiFi4, it has completely crushed the data. The maximum rate of WiFi6 can reach 9.6Gbps. It was born for the 5G era and optimizes the signal uplink coverage, which perfectly matches the NB-IoT Internet of Things.

Wi-Fi 6 mainly uses OFDMA, MU-MIMO and other technologies. MU-MIMO (Multi-User Multiple Input Multiple Output) technology allows the router to communicate with multiple devices at the same time. , rather than communicating sequentially. MU-MIMO allows the router to communicate with four devices at once, and Wi-Fi 6 will allow communication with up to eight devices. Wi-Fi 6 also utilizes other technologies such as OFDMA (Orthogonal Frequency Division Multiple Access) and transmit beamforming, both of which improve efficiency and network capacity respectively. Wi-Fi 6 has a maximum speed of 9.6Gbps.

A new technology in Wi-Fi 6 allows devices to plan communications with routers, reducing the time required to keep antennas powered up to transmit and search for signals, which means less battery drain and improved battery life Performance.

Wi-Fi 6 devices must use WPA3 in order to be certified by the Wi-Fi Alliance, so most Wi-Fi 6 devices will have stronger security once the certification program is launched.

What is the difference between WiFi6 and WiFi5

The difference is huge, whether it is protocol, working frequency band, maximum bandwidth, MCS Range, maximum modulation, single stream bandwidth, maximum spatial stream, etc. are all very different. With the WiFi5 protocol, wireless Internet speed rarely exceeds 500Mbps. Upgrading to a WiFi6 whole-house router allows wireless Internet speeds to reach up to 900Mbps.

This is actually determined by the threshold of the hardware itself. No matter how high the broadband rate is at home, the peak value of WiFi5 is only 867Mbps at most, while the WiFi6 protocol can reach a maximum of 1200Mbps. In addition to the improvement in Internet speed, the maximum number of devices that a WiFi6 router can theoretically connect to the Internet at the same time can reach 512, without even thinking about the WiFi5 protocol.
