SoC unlocks 20-MHz Wi-Fi 7 for smart IoT

According to Infineon, the AIROC ACW741x family of tri-radio SoCs features the first 20-MHz Wi-Fi 7 device designed for IoT applications. The device also integrates Bluetooth LE 6.0 with channel sounding, IEEE 802.15.4 Thread connectivity, and support for the Matter ecosystem—all in a compact QFN package.

Wi-Fi 7’s support for 20-MHz channel widths represents a meaningful expansion beyond conventional high-speed applications, especially for IoT devices. This enables lower power consumption, smaller form factors, and more reliable connectivity across a wider range of devices.

“With the recent extension of Wi-Fi Certified 7 capabilities to 20 MHz-only devices, Wi-Fi Alliance will deliver the benefits of Wi-Fi 7 for new device categories, enabling the next wave of IoT innovation across smart home, industrial, and healthcare settings,” said Kevin Robinson, CEO, Wi-Fi Alliance. The introduction of 20-MHz Wi-Fi 7 IoT solutions, such as those being introduced by Infineon, will unlock widespread Wi-Fi 7 adoption across the IoT market.”

The ACW741x supports Wi-Fi 7 multi-link operation (MLO), which enhances link reliability through adaptive band switching to reduce congestion and interference. By maintaining concurrent connections across 2.4-GHz, 5-GHz, and 6-GHz bands, Wi-Fi 7 multi-link for IoT provides a more consistent, always-connected experience for devices such as security cameras, video doorbells, alarm systems, medical equipment, and HVAC systems.

Integrated wireless sensing capabilities give smart IoT devices greater contextual awareness and allow them to share intelligence with other devices on the same network. Compared with other IoT Wi-Fi products, the ACW741x delivers up to 15× lower standby power consumption, extending battery life.

The ACW741x family is sampling now, along with hardware and software development kits.
