Fujitsu explores a "revolutionary" radio architecture for wireless IoT applications

Fujitsu Electronics Europe (FEEU) is working with the US-based company InnoPhase in exploring its extreme low-power PolaRFusion radio architecture for battery-based wireless IoT applications.

The revolutionary radio architecture moves RF processing functionality from power-hungry and large analog circuits into efficient, low-power digital logic. This opens new possibilities in the utilization of today’s WiFi, Bluetooth, Zigbee, and other popular protocol radios. The lower power consumption will enable a whole new class of battery-based IoT devices.

Immediately after the market launch of InnoPhase's first product at the beginning of 2018, the Talaria ONE ULP WiFi Radio, FEEU has been evaluating the potential of WiFi being available in battery-based applications. Based on customer feedback and ideas, InnoPhase is now planning to expand the device’s feature set in a new product coming soon in 2019.

“Within our focus on Ultra-Low Power and IoT applications, the FEEU Engineering is currently testing InnoPhase’s WiFi-based technologies in combination with the products of our other Ultra-Low Power vendors. We are working directly with InnoPhase to create a foundation to fully support this new technology in future FEEU projects in Europe.” said Dr. Klaus-Peter Dyck, FEEU’s Manager Marketing and Application.

With the commitment to bring feasible PolaRFusion solutions to customers, FEEU follows its claim as a Value Added Distribution Partner. “As a global technology gateway, we not only offer our customers a wide range of products and services for IoT and related application, but also employ experts to help customers to find the solutions that best meet their individual needs. This accelerates the search for new products and services and ultimately leads to a shorter time to market.” explained Axel Tripkewitz, FEEU’s President.

By combining Energy Harvesting from E-Peas with the Ultra-Low Power MCUs from Ambiq Micro and Fujitsu FRAM (Ultra-Low Power Non-Volatile Memory), InnoPhase’s PolaRFusion adds a new level of freedom in the selection of the used RF protocol while applications remain battery-based and energy-efficient. Selected application examples featuring the upcoming devices from InnoPhase will be made available by FEEU on the ClickBeetle reference platform
