Espressif will continue to invest in its hardware platforms, software support, and development tool ecosystem, giving developers and partners more open, complete, and easy-to-integrate solutions for the next generation of smart devices.
Espressif Systems (688018.SH) announced that the ESP32-E22 has been officially certified by the Wi-Fi Alliance as Wi-Fi CERTIFIED 6E™. At the same time, Espressif has released the open-source ESP32-E22 Linux driver on GitHub, providing complete software support for system integrators and developers.
About the ESP32-E22
The ESP32-E22 is Espressif's first tri-band Wi-Fi 6E connectivity coprocessor, designed for host-based wireless systems operating across the 2.4 GHz, 5 GHz, and 6 GHz bands. The chip uses a Radio Co-Processor (RCP) architecture, offloading Wi-Fi and Bluetooth protocol processing from the host so developers can pair it with Espressif SoCs or third-party processors for flexible system design. Built on Espressif's in-house dual-core RISC-V architecture and proprietary Wi-Fi 6E protocol stack, it delivers a stable, scalable foundation for next-generation products.
The ESP32-E22 is purpose-built for high-throughput, low-latency applications. It enables high-bandwidth streaming and wireless video links, supports next-generation smart-home hubs and connected appliances, and offers robust wireless performance for industrial automation, bridging solutions, and AR/VR accessories requiring low-latency communication. Combining 160 MHz channel bandwidth, 2×2 MU-MIMO, beamforming, and advanced link-layer scheduling, it sustains high throughput in dense, congested environments, with data rates of up to 2.4 Gbps.
Wi-Fi CERTIFIED 6E™
Wi-Fi Alliance certification verifies a product's compliance with Wi-Fi standards and its interoperability with other certified devices. For the ESP32-E22, it means reliable connectivity with the large global ecosystem of Wi-Fi CERTIFIED™ devices and confident deployment at scale.
As Wi-Fi 6E adoption continues to grow across consumer electronics, smart homes, industrial equipment, and enterprise networks, formal certification further strengthens customer confidence in product compatibility and long-term availability.
Open-Source Linux Driver
To help developers integrate and validate their products more quickly, Espressif has simultaneously open-sourced the ESP32-E22 Linux driver project. Designed for the Linux platform with support for kernel 5.4 and above, the driver enables device manufacturers and system developers to integrate the ESP32-E22 into a wide range of host systems. Developers can evaluate, customize, and extend the open-source code, lowering the barrier to development and accelerating the path from product design to mass production.
Continuing to Strengthen the Wi-Fi 6E Ecosystem
Wi-Fi CERTIFIED 6E™ certification marks an important milestone for Espressif in tri-band wireless connectivity. Looking ahead, Espressif will continue to invest in its hardware platforms, software support, and development tool ecosystem, giving developers and partners more open, complete, and easy-to-integrate solutions for the next generation of smart devices.
