Wi-Fi Alliance Certifies 6 GHz Wi-Fi 6E, Boosting Streaming Throughput and Latency
The Wi-Fi Alliance certified 6 GHz Wi-Fi 6E devices for operation in the 6 GHz band, opening new spectrum that is crucial for streaming. This development will lead to improved throughput and reduced latency for bandwidth-intensive applications. It signifies an important step in the evolution of Wi-Fi technology, including future Wi-Fi 7.
Key Takeaways
- Wi-Fi Alliance certified 6 GHz Wi-Fi 6E devices for operation.
- New 6 GHz spectrum is crucial for streaming applications.
- Expect improved throughput and reduced latency for bandwidth-intensive tasks.
- This certification is a step towards future Wi-Fi 7 development.
Why It Matters
The immediate availability of 6 GHz Wi-Fi 6E devices will alleviate network congestion and enhance performance for streaming services, particularly in dense environments. This expansion into new spectrum provides a dedicated 'fast lane' for compatible devices, crucial for applications like 4K video, VR, and cloud gaming. The ecosystem will likely see increased adoption of Wi-Fi 6E-enabled devices and infrastructure upgrades as consumers and enterprises seek to capitalize on these performance gains. What to watch next is the broader market adoption rates and real-world performance benchmarks of Wi-Fi 6E in diverse streaming use cases.
Additional Context
The activation of the 6 GHz band for Wi-Fi 6E has been a multi-year effort, stemming from the FCC's April 2020 decision to open 1200 MHz of spectrum for unlicensed use in the US (Cisco, undated). Other regions, including the European Union and parts of Asia, have also enabled some or all of the 6 GHz band for Wi-Fi, with over 30% of global GDP covered by these regulations, leading to a robust Wi-Fi 6E device ecosystem (Wi-Fi Alliance, November 2023). Industry analysts note that 2023 saw a significant ramp-up in Wi-Fi 6E shipments, particularly in the enterprise sector, with IDC forecasting 473 million Wi-Fi 6E devices to ship in 2023 alone (RCR Wireless News, November 2023). Major tech players are integrating 6 GHz capabilities, with Apple's 2023 lineup, including the iPhone 15, now supporting Wi-Fi 6E (RCR Wireless News, November 2023). However, for basic single-device 4K streaming, a 2019-2021 Wi-Fi 6 router often provides sufficient bandwidth, and upgrades to Wi-Fi 6E may only show significant benefits with multiple simultaneous 4K streams, latency-sensitive applications like VR, or severe existing network congestion (AliBaba LifeTips, undated). The progression towards Wi-Fi 7 (802.11be), with features like increased speeds up to 46 Gbps, lower latency through enhanced multi-link operation, and higher capacity, is already underway, with initial devices appearing in 2024 (Cisco, undated). Regulatory discussions are ongoing, particularly regarding the allocation of the upper 6 GHz band with cellular services, which could impact Wi-Fi's long-term access to this critical spectrum (Wi-Fi Alliance, November 2023).
