Called Airoc ACW741x, the family 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.
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.
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 claims to be the industry’s first product to support 20 MHz-only channels, with optimised radio performance and ultra-low power consumption.
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 connected experience for always-on applications.
The ACW741x also integrates wireless sensing capabilities, which adds contextual awareness to smart IoT devices to create differentiated offerings such as home automation and personalization. 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.
It combines transmit/receive switches, power amplifiers, low-noise amplifiers, power management, and a low-power oscillator in a a QFN package that enables low-cost two-layer PCB designs, the ACW741x provides a cost-efficient migration path to Wi‑Fi 7.
