NI’s integrated systems approach demonstrates
the benefits of digital envelope tracking for higher 5G mmWave
front-end efficiency
International Microwave Symposium (IMS) – NI (NASDAQ:
NATI) today 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. 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.
Full support of ETAdvanced was achieved using NI
software-connected PXI systems, making possible a tightly
synchronized combination of fine digital edge placement, as well as
wideband 5G new radio (NR) generation and analysis with the mmWave
Vector Signal Transceiver (VST). These technologies helped Eta
Wireless demonstrate a data rate improvement of 3X and the doubling
of the PA’s output power, addressing core power and thermal
problems of 5G mmWave deployments. The increase in range and
throughput for a given power budget makes ETAdvanced technology a
key enabler for mmWave 5G radios.
“At NI, we equip our customers to engineer ambitiously by
providing the tools and expertise required to help them test new
ideas,” said Ritu Favre, senior vice president and general manager
of NI’s semiconductor business unit. "Connecting Eta Wireless with
technology that helps solve one of the biggest challenges facing 5G
adoption is at the heart of our vision to accelerate 5G
commercialization.”
“NI’s PXI-based solution for RF and digital signal generation
extracts peak performance of ETAdvanced technology in the lab
setting. NI’s support for Digital ET will help mobile device
companies accelerate mmWave deployments and provide end customers
with a superior user experience,” said John Hoversten, chief
technology officer and founder of Eta Wireless. “We are pleased to
see the front-end ecosystem converging to Digital ET, which helps
extend much needed battery life for the mobile user while
delivering on the 5G promises of greater connectivity and higher
bandwidth.”
About NI 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.
About Eta Wireless 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. Unlike legacy
analog envelope tracking technologies, ETAdvanced supports new
gigabit communication standards for 5G, LTE Advanced, and
Wi-Fi.
Based on breakthrough research by two MIT professors, Eta
Wireless is headquartered in Cambridge, MA. The founders of Eta
Wireless previously built Eta Devices, a company providing proven
power management solutions for mobile base stations. Nokia acquired
Eta Devices in October 2016. Eta Wireless investors include Intel
Capital and Deutsche Telekom.
