> Here are some of the key features expected in WiFi 7:
* Up to 40 Gbps link
* Bandwidth up to 320 MHz and beyond
* Order of modulation up to 4K-QAM
* Up to 16x spatial streams in MU-MIMO
* Enhanced Distributed Channel Access (EDCA) with 802 TSN (Time-sensitive Networking) features for real-time applications
* Latency below 5 ms suitable for gaming
* Enhanced OFDMA for better resource allocation
* Multi-link operation favorable for both tremendous data rates and extremely low latency
* Channel sounding optimization to reduce overhead
* Introduction of HARQ (Hybrid Automatic Repeat Request) which “exploits the information from the previous tries. The receiver combines the signals from several transmission attempts, which increases SNR and, consequently, the probability that the receiver decodes the packet correctly.”
* Non-orthogonal Multiple Access (NOMA) to increase peak throughput and improve efficiency by making an access point (AP) serve multiple stations/clients (STAs) simultaneously in the same baseband by allocating portions of the total transmission power for each STA
* Multi-AP cooperation with techniques such as coordinated spatial reuse (CSR) or coordinated OFDMA (CO-OFDMA) in dense deployments
> MediaTek says products with Wi-Fi 7 are expected to hit the market starting in 2023, but the development timeline from the May 2020 document above expects the final amendment to occur in May 2024. I’ve seen companies launch products based on draft specifications before, but obviously, there’s a certain level of risk as the products may end up not being fully compatible depending on how the draft specifications are amended.
Based on this information, I imagine we should look for Wi-Fi 7 on phones and laptops sometime in 2025? Anyone reading this have a Wi-Fi 6E access point? Can you please share your story?
