What is Wi-Fi 7, and will it replace wired Ethernet?

As the global technological landscape evolves at an astonishing pace, it’s crucial to stay updated on the latest advancements that shape connectivity. Amidst the already established Wi-Fi standards like Wi-Fi 5, Wi-Fi 6, and Wi-Fi 6E, the introduction of Wi-Fi 7 has stirred the tech sphere. Chinese networking-equipment vendor H3C has taken a bold step by launching a Wi-Fi 7 router, even though the standard is not expected to be finalized until 2024. This development holds significance for the technology enthusiasts and businesses in the UAE, particularly in Dubai’s thriving tech ecosystem.

Introducing Wi-Fi 7: Navigating the Speeds and Features

• Defining Wi-Fi 7: Wi-Fi 7, also known as 802.11be, is the upcoming standard under development by the Institute of Electrical and Electronics Engineers (IEEE). It promises an astounding speed of 46Gbps, nearly five times faster than Wi-Fi 6, along with reduced latency.
• Enhancements and Features: Wi-Fi 7 aims to deliver higher spectrum efficiency, improved power efficiency, enhanced interference mitigation, increased capacity density, and better cost efficiency. These attributes align with Dubai’s commitment to technological advancement.

Unveiling the Functionality of Wi-Fi 7: A Glimpse into Its Capabilities

Wi-Fi 7 is engineered to revolutionize wireless connectivity through a series of enhancements:

• Doubled Channel Size: Wi-Fi 7 doubles the maximum channel size from 160MHz to 320MHz, immediately doubling the throughput. It provides flexibility, enabling networks to run either two 160MHz channel sets or one channel at 320MHz, catering to varied application needs.
• Increased MU-MIMO Spatial Streams: With Wi-Fi 7, the number of spatial streams increases from eight to 16, effectively doubling the throughput. Multi-user, multiple-input, multiple-output (MU-MIMO) technology ensures equitable distribution of available bandwidth among streams, reducing congestion.
• Quadrupled QAM: By elevating quadratic amplitude modulation (QAM) from 1024-QAM to 4096-QAM, Wi-Fi 7 achieves an additional 20% boost in throughput, progressing from 9.6Mbps in Wi-Fi 6 to 46Mbps.
• Multi-Link Operation (MLO): MLO empowers devices to simultaneously transmit and receive across various bands and channels, enhancing performance, reducing latency, and elevating reliability. This holds significant promise for Dubai’s burgeoning IoT landscape.
• Multi-AP Operation: Wi-Fi 7 introduces multi-AP operation, a mesh-like configuration where neighboring access points collaborate, optimizing spectrum and resource utilization. Dubai’s tech-savvy environment stands to gain from such enhancements.

Wi-Fi 7’s Relevance in UAE’s Digital Evolution

Wi-Fi 7’s capabilities align with UAE’s tech ambitions and Dubai’s smart city aspirations:
