What are the Differences Between WiFi 4, WiFi 5, and WiFi 6?
Definition of WiFi 4, WiFi 5, and WiFi 6 WiFi 4: Originally named 802.11n, released in 2009. It uses multiple-input multiple-output (MIMO) technology to transmit data through multiple antennas simultaneously, improving transmission speed and network capacity. In addition, WiFi 4 also introduces backward compatibility technology so that new devices can work with old devices. WiFi 5: Originally named 802.11ac, released in 2013. It further improves transmission speed and network capacity, and uses more advanced modulation technology. In addition, WiFi 5 also introduces directional antenna technology, which enables devices to transmit data more accurately and improves signal coverage. WiFi 6: The original name is 802.11ax, released in 2019. It uses more advanced signal processing technology to enable devices to better collaborate and share network resources. In addition, WiFi 6 also introduces context-aware technology, which automatically adjusts the transmission rate and signal powe...
