Infineon Technologies is accelerating its push into the next-generation IoT market with the launch of the AIROC™ ACW741x family of Wi-Fi 7 IoT tri-radio devices, the industry's first to support the 20 MHz band.

Infineon today announced the launch of its new AIROC™ ACW741x family to support the continued growth of connected devices in the home, industrial and commercial markets.

This new product, which integrates Wi-Fi 7, Bluetooth® LE 6.0, and IEEE 802.15.4 Thread on a single chip, is designed to implement high-reliability, low-power wireless connectivity required in smart home, industrial automation, and commercial IoT environments.

With the number of IoT connected devices worldwide projected to reach 30 billion by 2030, manufacturers need next-generation wireless solutions that deliver energy efficiency, cost effectiveness, and reliability.

The Wi-Fi Alliance's newly defined 20 MHz Wi-Fi 7 category for the IoT ecosystem reflects these needs, and Infineon's ACW741x is the first product to implement this specification.

ACW741x is a Wi-Fi 7 multi-band router for IoT.-By applying link technology, it utilizes 2.4 GHz, 5 GHz, and 6 GHz bands simultaneously, maintaining a stable connection even in congested wireless environments.

This provides latency-free communication quality in applications where constant connectivity is essential, such as security cameras, video doorbells, alarm systems, medical devices, and HVAC systems.

In particular, the Adaptive Band Switching feature significantly improves link reliability by minimizing interference.

Power efficiency is also a key competitive advantage for this product line. Infineon achieved the industry's lowest Wi-Fi standby power through an optimized 20 MHz design, achieving up to 15 times lower power consumption than existing IoT Wi-Fi products.

This can dramatically extend the lifespan of battery-based IoT devices, making them suitable for ultra-low-power applications such as door locks, thermostats, and smart sensors.

“As smart homes and commercial environments become increasingly complex, Infineon is enhancing the connectivity of IoT devices with high-performance, low-power, and integrated wireless solutions,” said Sivaram Trikutam, Senior Vice President and General Manager of Infineon’s Wireless Products Division. “The ACW741x is the industry’s lowest standby power tri-band single-chip, which will provide reliable performance in diverse IoT environments.”

The ACW741x also supports wireless sensing capabilities. Wi-Fi Channel State Information (CSI)-based 802.11bf technology enhances environmental awareness by enabling intelligent sharing between devices within a network, while channel sounding technology enables centimeter-precise distance measurements. This enables the development of differentiated services such as home automation, security, and personalized user experiences.

Additionally, the chip integrates a transmit/receive switch, a power amplifier, a low-noise amplifier, and power management circuitry, and uses a QFN package that supports low-cost 2-layer PCB design, enabling manufacturers to easily transition to Wi-Fi 7-based products.

“Wi-Fi 7 significantly improves the predictability and reliability of IoT devices in dense environments,” said Kevin Robinson, CEO of the Wi-Fi Alliance. “The expansion of 20 MHz-only device certification will spur new innovation across smart home, industrial, and healthcare.”

The Infineon ACW741x family is currently sampling and product development is possible via hardware and software development kits.
