Wi-Fi 7: The Next Generation of Wireless Connectivity
Wi-Fi 7 is the newest standard in wireless technology, designed to deliver faster speeds, lower latency and greater reliability. This advancement promises to significantly surpass the capabilities of its predecessors, Wi-Fi 6 and Wi-Fi 6E. Although official ratification of the 802.11be standard by the IEEE (Institute of Electrical and Electronics Engineers) has already taken place, its wide-scale adoption is just beginning in 2025.
What is Wi-Fi 7?
Wi-Fi 7, technically identified as 802.11be, corresponds to a compatibility certification by the Wi-Fi Alliance. This new standard under development focuses on providing extremely high throughput EHT (Extremely High Throughput) and improving latency.
In practical terms, Wi-Fi 7 represents an evolution of the current Wi-Fi 6 and 6E technologies, refining and extending their capabilities to meet the most demanding requirements.
Evolution of recent Wi-Fi standards
- Wi-Fi 6 (802.11ax, High Efficiency - HE): Introduced improvements in operational efficiency and support for the 2.4 GHz, 5 GHz and, in some cases, 6 GHz bands.
- Wi-Fi 6E (802.11ax, Extended - E): Expansion of Wi-Fi 6 to take advantage of the new 6 GHz band, improving capacity and reducing congestion.
- Wi-Fi 7 (802.11be, Extremely High Throughput - EHT): Focuses on maximizing throughput, reducing latency and increasing redundancy through innovations such as multi-link operation (MLO).
Main new features of Wi-Fi 7
1. Multi-Link Operation (MLO): Allows devices to use multiple channels simultaneously, even in different bands (e.g., 5 GHz and 6 GHz).
Benefits: Increases speed and reliability by combining frequencies.
Reduces latency by avoiding congested frequencies. It is especially useful in dense environments or Wi-Fi mesh systems, although it could impact battery consumption in mobile devices.
2. 4096-QAM modulation:
Increases data throughput by 17% over 1024-QAM.
Requires optimal conditions, such as line-of-sight and high signal-to-noise ratio (SNR) levels.
Well-planned Wi-Fi designs can take advantage of this technology in most cases.
3. 320 MHz channels:
They offer higher transmission capacity.
However, their use in enterprise environments is limited due to interference and network density issues.
The future of 6 GHz Wi-Fi
While Wi-Fi 7 introduces significant innovations, adoption of the 6 GHz band will remain a key driver for superior performance and higher capacity in enterprise networks.
Should you wait or upgrade now?
If you need to upgrade your Wi-Fi network right now, opting for Wi-Fi 6E may be the best decision. This standard already provides advanced capabilities in the 6 GHz band and meets most business needs. With tools like Ekahau AI Pro, it is possible to design a flawless network, ready for future upgrades to Wi-Fi 7.
Wi-Fi 7 represents a significant step in the evolution of wireless networks, although mass adoption will take a few years. In the meantime, a well-designed Wi-Fi 6E network will allow you to enjoy a robust and scalable wireless experience, while paving the way for the transition to the new standard.
