NI, Eta Wireless Accelerate Development of Wideband Digital Envelope Tracking

International Microwave Symposium (IMS) — NI (NASDAQ: NATI) has announced its collaboration with Eta Wireless to implement and demonstrate full support of ETAdvanced, the industry´s first ever Digital Envelope Tracking (ET) technology for mmWave 5G RF front-end devices, the company said.

Developed by Cambridge-based Eta Wireless, the technology enables extended battery life in smartphones, wearables, and Internet of Things (IoT) devices, improving both data rates and connectivity range.

ETAdvanced addresses the power efficiency challenges that have historically plagued RF front-ends. Wideband power amplifiers (PAs), such as those found in 5G devices, waste a significant amount of power in the form of heat, greatly reducing battery life. ETAdvanced uses the signal´s envelope information to increase the amplifier´s efficiency by delivering only the power needed at that instant.

At NI, we bring together the people, ideas and technology so forward thinkers and creative problem solvers can take on humanity´s biggest challenges. From data and automation to research and validation, we provide the tailored, software-connected systems engineers and enterprises need to Engineer Ambitiously™ every day.

Eta Wireless is solving the fundamental power challenges in the mobile communications industry. Today´s smartphones, wearables, and Internet of Things (IoT) devices are highly energy inefficient and typically waste most of the power consumed as heat. Eta Wireless´ technology, ETAdvanced, dramatically reduces energy consumption to extend the battery life of all wireless communication devices significantly.
