Infineon introduces the industry’s first Wi-Fi 7 IoT 20 MHz tri-radio device optimised for IoT
To support continued growth of connected devices in home, industrial and commercial markets, Infineon has introduced the AIROC ACW741x, a new product family that integrates a tri-radio with Wi-Fi 7, Bluetooth LE 6.0 with Channel Sounding, and IEEE 802.15.4 Thread, with Matter ecosystem support in a single device. This product family introduces the industry’s first 20 MHz Wi-Fi 7 device for IoT, provides Wi-Fi 7 Multi-Link for IoT for enhanced robustness in congested environments and has the industry’s lowest Wi-Fi connected standby power.
With the IoT connectivity market projected to reach 30 billion devices by 2030 [1], IoT device manufacturers continue to demand reliable, energy-efficient and cost-effective solutions. The Wi-Fi Alliance is introducing the 20 MHz device category for Wi-Fi 7 aimed at addressing the needs of the broader IoT ecosystem, and the AIROC ACW741x is the industry’s first product to support 20 MHz-only channels, with optimised radio performance and ultra-low power consumption.
As Wi‑Fi–connected IoT devices proliferate across homes and commercial environments, spectrum congestion and interference increasingly undermine wireless connectivity and performance. With Wi‑Fi 7 Multi‑Link for IoT, the ACW741x boosts link reliability with Adaptive Band Switching to mitigate congestion and interference. By maintaining concurrent links across 2.4, 5, and 6 GHz, Wi‑Fi 7 Multi‑Link for IoT delivers a more consistent, always‑connected experience for applications such as security cameras, video doorbells, alarm systems, medical devices, and HVAC systems.
The Infineon ACW741x product family has an optimised 20 MHz design to achieve the industry’s lowest power consumption, and is ideal for battery-operated applications such as security cameras, door locks, and thermostats that require ultra-low Wi-Fi connected standby power. Compared to other IoT Wi-Fi products on the market, the ACW741x offers up to 15x lower standby power consumption, which delivers significantly longer battery life.
The ACW741x also integrates wireless sensing capabilities, which adds contextual awareness to smart IoT devices to create differentiated offerings such as home automation and personalisation. Wi-Fi Channel State Information (CSI) 802.11bf enables enhanced Wi-Fi sensing with intelligence sharing between same-network devices, whereas Channel Sounding delivers accurate, secure, low-power ranging with centimeter-level accuracy.
Combining extensive on-chip integration—including transmit/receive switches, power amplifiers, low-noise amplifiers, power management, and a low-power oscillator—with a QFN package that enables low-cost two-layer PCB designs, the ACW741x provides a cost-efficient migration path to Wi‑Fi 7.
