Wi-Fi 7 Introduction

Use this topic to get a quick, high-level introduction to the key features in Wi-Fi 7.

The IEEE 802.11be Extremely High Throughput (EHT) standard, more commonly known as Wi-Fi 7, introduces new features and delivers several major improvements over Wi-Fi 6 and Wi-Fi 6E.

Wireless (Wi-Fi) networking has undergone several updates since its original introduction. Each update has included some combination of improved speed, increased throughput, increased range, increased security, and other improvements.

The following lists the most significant features that changed or were introduced with the Wi-Fi 7 update.

Wi-Fi 7 (802.11be)

  • Extremely High Throughput (EHT)—potentially offers speeds up to 46 Gbps on the 6 GHz frequency band.

  • 320 MHz Channels—double the maximum channel width compared to Wi-Fi 6, providing increased bandwidth.

  • Multi-Link Operation (MLO)—allows devices to connect across multiple frequency bands simultaneously, improving reliability and speed.

  • Improved MU-MIMO—supports more simultaneous data streams for enhanced multi-device performance.

  • Improved OFDMA—further optimizes network capacity and efficiency.

  • Multi-Resource Unit (Multi-RU)—allows transmission on more than one RU

  • Preamble Puncturing—allows partial channel use when interference is present.

  • Reduced Latency—enhanced features for gaming and real-time applications.

  • Target Wake Time (TWT) Enhancements—further improvements in power efficiency for IoT and battery-powered devices.

  • Support for New Modulation Schemes—incorporates advanced modulation techniques for higher data rates.

  • Integrated Wireless Security—this security posture is a shift from previous Wi-Fi standard upgrades that focused on physical layer and MAC features only. Wi-Fi 7 Security enhancements include:

    • Mandatory WPA3 adoption

    • Updated requirements for 6 GHz operation

    • Stricter compliance for device interoperability around authentication and encryption

  • Backward Compatibility—Backward compatibility enables a Wi-Fi 7 network to support legacy client devices. Enabling legacy clients to connect to your Wi-Fi 7-capable network has implications for the network and newer client devices.

These features represent the progression in Wi-Fi technology, focusing on faster speeds, increased capacity, improved efficiency, improved security, and better support for multiple devices and applications.
