What Is Wi-Fi 7 (IEEE 802.11be)?

Wi-Fi 7 is officially standardized as IEEE 802.11be, also referred to as Extremely High Throughput (EHT) Wi-Fi.
Its primary objectives are:

• Significantly higher wireless throughput

• Ultra-low latency for real-time applications

• Improved reliability in congested environments

• Better scalability for high-density device deployments

Unlike previous Wi-Fi generations, Wi-Fi 7 focuses not only on raw speed but also on link efficiency and intelligent traffic management.

Key Wi-Fi 7 Technologies and Features

1. 320MHz Ultra-Wide Channel Bandwidth

Wi-Fi 7 doubles the maximum channel width from 160MHz (Wi-Fi 6E) to 320MHz, primarily in the 6GHz band.

Benefits of 320MHz channels:

• Massive throughput increase

• Higher sustained speeds for data-intensive applications

• Reduced interference in high-traffic environments

This feature is a major contributor to the dramatic improvement in Wi-Fi 7 speed.

2. 4096-QAM (4K QAM) Modulation

Wi-Fi 7 introduces 4096-QAM, enabling each symbol to carry 12 bits of data.

Performance impact:

• Approximately 20% higher data efficiency compared to 1024-QAM

• Improved peak throughput in optimal signal conditions

To support 4K QAM, Wi-Fi 7 routers and access points require advanced RF and chipset designs.

3. Multi-Link Operation (MLO)

Multi-Link Operation (MLO) is the most transformative innovation in Wi-Fi 7.

With MLO, devices can simultaneously transmit and receive data across multiple bands, such as:

• 5GHz + 6GHz

• 2.4GHz + 5GHz

• Multi-band parallel connections

Advantages of MLO:

• Ultra-low latency

• Reduced packet loss and jitter

• Higher connection reliability through link redundancy

MLO makes Wi-Fi 7 particularly suitable for cloud gaming, real-time video conferencing, XR, and industrial networking.

4. Enhanced MU-MIMO and OFDMA

Wi-Fi 7 builds upon Wi-Fi 6 by further optimizing multi-user technologies:

• MU-MIMO: Supports up to 16×16 streams

• OFDMA: More flexible resource unit (RU) allocation

Resulting improvements:

• Better performance in high-density environments

• More consistent throughput for multiple devices

• Efficient coexistence of IoT and high-bandwidth applications
