Wi-Fi 7 explained WiFi 7 is the upcoming WiFi standard, also known as IEEE 802.11be Extremely High Throughput (EHT). It works across all three bands (2.4 GHz, 5 GHz, and 6 GHz) to fully utilize spectrum resources. While WiFi 6 was built in response to the growing number of devices in the world, WiFi 7's goal is to deliver astounding speeds for every device with greater efficiency. If you're struggling with constant buffering, lag, or congestion, a WiFi 7 router may be your best solution.

WiFi 7 introduces 320 MHz ultra-wide bandwidth, 4096-QAM, Multi-RU, and Multi-Link Operation to provide speeds 4.8× faster than WiFi 6 and 13× faster than WiFi 5. Unlock more scenarios than ever before. Wi-Fi 7 delivers features based on the new 802.11be standard and extends the capabilities of Wi-Fi 6E. Although Wi-Fi 7 is not yet finalized, capabilities include: l 320 MHz bandwidth channels l Multi-link operation (MLO) for channel aggregation across different bands and failover l 4096 QAM (4k QAM) for higher peak data rates l Spectrum puncturing to better accommodate inteRFerence in wide channelsAs part of the certification process, the Wi-Fi Alliance will determine which features are required and which are optional. Benefits of Wi-Fi 7 Whether at home on a Wi-Fi 7 router or in the enterprise wireless network setting, Wi-Fi 7 should shine in the areas of higher speeds, reduced latencies and the ability to handle higher client densities with each individual user having better connections. Wi-Fi technology is at a point where it may finally compete with Ethernet for speed and reliability. Everything from cloud applications to virtual reality and the highest-resolution video will all benefit when run on Wi-Fi 7 clients connected to a properly designed Wi-Fi 7 network. When will Wi-Fi 7 be available? Wi-Fi 7 is expected to be ratified in early 2023. Wi-Fi fans can follow IEEE's progress on the standard here. Ratification, though, does not mean wide availability of products. The bigger players in the wireless local area network (WLAN) industry probably won't give Wi-Fi 7 legitimate attention until well into 2024. As with all 802.11 standards, the market should see consumer-grade offerings well ahead of enterprise gear. What does the future look like for Wi-Fi? It's hard to say what Wi-Fi 8 might look like, but count on new or improved features and better QAM, leading to new maximum theoretical data rates. Also, expect Wi-Fi products to trend evermore expensive on both the consumer and enterprise side. For business WLAN systems, Silicon Valley will continue the trend of licensing Wi-Fi products in creative ways to keep shareholders happy. Other safe bets are the push for cloud management strategies and elaborate performance monitoring dashboards -- all also heavily licensed in exchange for the new performance capabilities.
) M+ c: K6 T2 [What is the regulatory status of Wi-Fi 7? Wi-Fi 7 is tied to the IEEE standard 802.11be, which is still under review. Wi-Fi Alliance is in the process of defining the criteria for Wi-Fi 7 certification, which is anticipated late 2023 or early 2024. 3 A. r+ M! {* ^ b& a5 ], a
