![]() This protocol focuses on indoor and outdoor operations with stationary and mobile speeds in the 2.4, 5 and 6 GHz frequency bands, and a goal of supporting a maximum throughput of at least 30 Gbps (with the potential of reaching 46 Gbps), while ensuring backwards compatibility. This version is still in the draft stages with final approval expected in 2024 (although products will likely be out sooner once the draft protocols are approved). The successor to Wi-Fi 6 and 6E is the 802.11be standard, labeled by the Wi-Fi Alliance as Wi-Fi 7. Wi-Fi 7 (802.11be): Extremely High Throughput Additional use cases include unified communications, cloud computing and telepresence, as well as accelerate next-generation connectivity with 5G networks. Devices that use 6E can deliver greater network performance and support more Wi-Fi users at once, even in dense and congested environments, the Wi-Fi Alliance says. ![]() Wi-Fi 6E extends the protocol into the 6 GHz frequency band and can utilize up to 14 additional 80 MHz channels, or seven additional 160 MHz channels, for applications such as high-definition video and virtual reality. Wi-Fi 6 promises at least a 4X improvement in throughput compared to 802.11n and 802.11ac., through more efficient spectrum utilization. Known as High Efficiency WLAN, 802.11ax aims to improve performance in dense scenarios, such as sports stadiums and airports, while still operating in the 2.4GHz and 5GHz spectrum. Wi-Fi 6 and 6E (802.11ax): High Efficiency WLAN Newer home routers and new devices now feature Wi-Fi 6 and/or 6E support. Some router vendors include technologies that support the 2.4GHz frequency via 802.11n or Wi-Fi 4, providing support for older client devices that may have 802.11b/g/n radios, but also providing additional bandwidth for improved data rates. ![]() With Multiple Input, Multiple Output (MIMO) technology – multiple antennas operating on both sending and receiving devices to reduce errors and boost speed – this standard supports data rates up to 3.46Gbps. Older home wireless routers are likely 802.1ac compliant and operate in the 5 GHz frequency band. You can also view a timeline of these standards at the IEEE website. The following is an explanation of Wi-Fi standards broken into four sections: popular core standards, future standards that are still under development, standards that are designed for niche applications and historical standards that might not be in use anymore.
