Eta Devices Introduces ETAdvanced for 802.11ac WiFi

 

ETAdvanced slashes power consumption by 80%, extends battery life and enables gigabit communication for smartphones and wearable devices at up to 160 MHz signal bandwidth

 

 
EUROPEAN MICROWAVE WEEK, ROME, October 6, 2014 -- Eta Devices, Inc. today announced that ETAdvanced is now available for 802.11ac bringing the benefits of the world’s most efficient power amplifier technology to WiFi networks.

 

The announcement follows Eta Devices’ introduction of ETAdvanced for LTE in February at the Mobile World Congress. The WiFi solution announced today includes the Eta6 power management chip together with reference designs for smartphones.

 

“Eta6 is truly a game-changing innovation for the mobile industry,” said Gene Tkachenko, executive vice president at Eta Devices. “A state-of-the-art 802.11ac power amplifier (PA) controlled by ETAdvanced consumes 80% less power than a typically deployed 802.11ac PA; this is no small feat. ETAdvanced also supports channel bandwidth up to 160 MHz, by far exceeding the capabilities of existing technologies. ETAdvanced is the first time that an advanced supply modulation technology has been demonstrated for ultra high bandwidth applications.”

 

802.11ac is the next-generation WiFi standard that operates on the less crowded 5GHz band, so it provides a more robust wireless signal and makes throughput faster because it can support speeds over 1Gbps. For phone users, 802.11ac means improved performance with tasks such as streaming and sharing data between devices in a home network, and better coverage receiving Wi-Fi in places that may have been dead zones with legacy phones.

 

ETAdvanced significantly reduces power consumption, resulting in less need for heat dissipation which can help wearable designers optimize for customer experience rather than engineering considerations. In addition to providing significant power savings, the Eta6 power management chip is also a fraction of the size of previous power management technologies including envelope tracking. This is important for both smartphones and the emerging field of wearable electronics where the small form factor of the devices puts space at a premium.

“ETAdvanced solves the power challenges for smartphones and wearables running 802.11ac and/or LTE,” said Mattias Åström, CEO and co-founder of Eta Devices. “ETAdvanced solves all of these issues in one go, extending battery life while reducing heat dissipation which vastly improves the customer experience. And we do this while saving footprint in the device at the same time as we support MIMO and ultrawideband channels of up to 160 MHz. No other efficiency enhancing technology comes even close to delivering these benefits.”

World Economic Forum Names Eta Devices 2015 Technology Pioneer

Selected for technology advances developed at MIT that dramatically reduce
energy consumption of mobile base stations and smartphones


Cambridge, MA, August 26, 2014 -- Eta Devices, Inc. today announced that it has been named a 2015 Technology Pioneer by The World Economic Forum (WEF) for its groundbreaking technology that dramatically reduces the energy consumption of mobile base stations and smartphones. The company joins a thriving community of previous WEF Technology Pioneers including AirBnB, Nest Labs, Dropbox, Kickstarter, Spotify and Twitter to name just a few recent recipients.

 

Mobile communications is experiencing explosive growth with nearly 7 billion mobile subscribers around the globe. However, the energy efficiency of mobile networks is extremely low.

 

“Mobile networks regularly waste 70% of the energy used as heat. That’s nearly as bad as incandescent light bulbs,” said Joel Dawson, CTO and co-founder of Eta Devices. “This is because the power architecture of mobile communications still essentially relies on technology from the 1930s. It is time for a 21st century solution to a 21st century problem.”

 

Based on 10 years of research at MIT, Eta Devices has solved the fundamental challenge in mobile communications of simultaneously achieving low energy consumption and utilizing the radio spectrum in a highly efficient manner. Previously, there has been a tradeoff that has resulted in lower and lower energy efficiency as more and more mobile subscribers compete for a limited amount of radio spectrum and use high bandwidth communications protocols like LTE. ETAdvanced, Eta Devices’ new power architecture, solves this classic dilemma by working like a car’s automatic transmission, constantly providing exactly the right amount of power needed for the radio signal at any given time. The result is an 80% reduction in the amount of heat waste over conventional mobile power amplifiers deployed in today’s base stations.

The impact of ETAdvanced is significant and includes the following:

 

  • Saving at least USD 18 billion in utility costs for mobile operators.
  • Reducing annual greenhouse gas emissions from mobile communications corresponding to the emissions from nearly 5 million American homes.
  • Extending the battery life in smartphones by at least 50%.
  • Enabling base stations powered exclusively by renewable energy to bridge the digital divide and bring the benefits of communications to the 1.7 billion people currently living off electricity grids.

 

“ETAdvanced is a technology without drawbacks.  We work hard to reduce costs for mobile operators, extend the battery life of smartphones, and bring mobile communications to underserved parts of the world which contributes to a greener and cleaner planet,” said Mattias Astrom, CEO, Eta Devices. “We believe that technology can make a real difference towards creating a better world for us all and we are extremely proud to be honored for our efforts by the World Economic Forum, one of the world’s most respected organizations.”

 

Eta Devices will receive the award from the World Economic Forum at the eighth Annual Meeting of the New Champions 2014, in Tianjin, People’s Republic of China, from September 10-12.  http://wef.ch/tp

Eta Devices Launches ETAdvanced
Feb 24, 2014

Eta Devices Launches ETAdvancedNext Generation Envelope Tracking for Smartphones

 

ETAdvanced brings game-changing battery-life improvements to smartphones including support for LTE Advanced and CMOS PAs


BARCELONA, February 24, 2014 -- Eta Devices, Inc. is launching Eta5, the world’s first smartphone power management chip for ETAdvanced at the 2014 Mobile World Congress in Barcelona, Spain from February 24-27.

 

“ETAdvanced is the future of envelope tracking and we’re proud to be the first company to bring this next generation technology to the market,” said Mattias Astrom, CEO and founder of Eta Devices. “Everyone is increasingly frustrated by the short battery lives of their smartphones. ETAdvanced extends the battery life by up to 50% by significantly increasing the efficiency of the power amplifier which consumes as much as 70% of the power in a smartphone.”

 

Mobile communications is experiencing explosive data growth and LTE is rapidly becoming the leading technology. At the end of 2013, the global telecom industry trade association, GSMA, recorded 230 LTE network deployments and projected over 1 billion customers on LTE networks by 2017. To meet the demands of increasingly data hungry customers, future LTE deployments will focus on LTE Advanced, the latest version of the LTE standard.

 

“A challenge with LTE Advanced is that the technology is using ultra wideband channels of up to 100 MHz,” said MIT Professor Joel Dawson, CTO and founder of Eta Devices. “No existing efficiency enhancing technology, including envelope tracking, is capable of supporting channels wider than 20-40 MHz. Once LTE Advanced is launched by mobile operators, smartphones without ETAdvanced will suffer from significantly shorter battery life compared to today, and many users may find themselves out of battery by lunchtime. This means users will only really get to enjoy the benefits of LTE Advanced if the technology is coupled with ETAdvanced in smartphones. Otherwise, LTE Advanced will remain a showcase technology at Mobile World Congress but without practical use to consumers.”

 

Beyond increasing the efficiency of conventional GaAs PAs, the additional improvements of ETAdvanced make it possible for CMOS PAs to operate more efficiently than the best GaAs PAs deployed today. Previously the efficiency of CMOS PAs has been too low for inclusion in smartphones.

 

“Increasing the efficiency of CMOS PAs has been the Holy Grail in the semiconductor industry for a long time. Before ETAdvanced, no technology has been able to deliver the required efficiency levels. This is a truly disruptive innovation that will reshape the industry,” said Astrom.

 

“With its many advantages available already today, ETAdvanced is the only future-proof efficiency enhancing technology on the market,” said Astrom. “Envelope tracking was a good first step forward for the industry, but the technology needed to mature into ETAdvanced before real world performance benefits could be delivered.”

 

Eta Devices is a spin-off from the electrical engineering department at the Massachusetts Institute of Technology (MIT). The company’s new patented ETAdvanced technology is building on Asymmetric Multilevel Outphasing (AMO) developed at MIT. ETAdvanced is a platform technology with applications for mobile stations, smartphones, tablets and laptop computers.

 

During the Mobile World Congress in Barcelona, Eta Devices will demonstrate the full power of ETAdvanced for LTE Advanced with transmission over 80MHz channels. If you are a member of the press or the CTO of a major mobile operator, please contact Greg Spector press@etadevices.com to book a personal meeting or demonstration during the Mobile World Congress.

Eta Devices Launches World’s Most Efficient Power Amplifier for Mobile Base Stations
Nov 12, 2013

Doubles Efficiency: Slashes Operators’ Greenhouse Gas Emissions & Utility Bills

 

TELCO ENERGY & INFRASTRUCTURE CONFERENCE, LONDON – November 12, 2013 – Eta Devices, Inc. today announced availability of the world’s most efficient power amplifier for mobile base stations, using new patented technology that exploits the extreme performance capabilities of GaN switching power amplifiers, advanced supply modulation and digital predistortion algorithms.

 

“Our power amplifier architecture brings real sustainability to the world’s mobile operators,” said Mattias Åström, Eta Devices’ co-founder and CEO. “We deliver 70% drain efficiency for 4G LTE – an industry first. By deploying our solution, base station efficiency is doubled compared to current state-of-the-art technology, which saves a tremendous amount of power.”

 

Eta Devices, a spin-off from the electrical engineering department at the Massachusetts Institute of Technology (MIT), first demonstrated its new power amplifier technology at the 2013 Mobile World Congress in Barcelona in February.

 

“Until today, mobile operators have not been able to build genuinely sustainable mobile networks,” said Joel Dawson, MIT professor and Eta Devices co-founder and Chief Technology Officer. “They have had no choice other than to focus on relatively minor sustainability initiatives such as changing the vehicle fleet to improve fuel economy, office recycling and substituting some flights with video conferences. While commendable, these initiatives have not touched on the operators’ core business of running mobile networks and as a result the impact has been relatively minor. But, there’s a new game in town. Operators can now double the efficiency of their mobile networks and realize substantial reductions in power usage, resulting in a major reduction in greenhouse gas emissions, and at the same time huge cost savings from using less power.”

 

On a global level, mobile networks consume approximately 120TWh of electricity per year.

 

“If Eta Devices’ solution is deployed on a worldwide basis by mobile operators, it would result in a reduction of greenhouse gas emissions equivalent to taking more than 7 million cars off the road” said Åström. “It would also save mobile operators $18 billion per year in utility costs thereby paying for the replacement many times over.”

 

Prof. Dawson’s presentation at the Telco Energy & Infrastructure Conference, titled “Beyond Token Gestures - Delivering Sustainable Mobile Networks”, will take place at 16:30 today, withan additional panel discussion at 10:00 on November 13. Both sessions are being held at the 15 Hatfields Conference Center. For more information, or to schedule an interview, please e-mail greg@etadevices.com.

Cree and Eta Devices to Demonstrate the World’s Most Efficient Power Amplifier (70%+) for Mobile Base Stations at the 2013 Mobile World Congress in Barcelona
Feb 20, 2013

Collaboration Establishes New Industry Standard with Significant Energy and Carbon Footprint Reductions 

 

DURHAM, NC and CAMBRIDGE, MA – February 20, 2013 – Cree, Inc. (Nasdaq: CREE) and Eta Devices, Inc. will demonstrate the world’s most efficient reported power amplifier for mobile base stations at the 2013 Mobile World Congress, February 24-28 in Barcelona, Spain. 


Current generation mobile base station amplifiers employing silicon LDMOS transistors can provide amplifier efficiencies up to 45 percent. By contrast, Eta Devices’ next-generation power amplifiers are able to deliver efficiencies higher than 70 percent under a 4G LTE modulation format, and are thus poised to revolutionize current industry efficiency standards.
 

“Eta Devices’ next-generation power amplifiers leverage the performance and reliability advantages of Cree’s GaN HEMT RF transistors to realize game-changing efficiency benefits for the mobile base station industry,” said Jim Milligan, business director, Cree RF. “Our transistors have been instrumental in demonstrating Eta Devices’ amplifiers, which perform 50 percent more efficiently than the best incumbent silicon power amplifiers currently available in the 4G LTE market.”
 

The world’s mobile networks consume approximately 120TWh of electricity per year, and 50-80 percent of these networks’ power is consumed by their power amplifiers and associated components. Implementing Eta Devices’ new power amplifier solution on a global level could save mobile operators 60TWh of energy per year, which is equivalent to the amount of power produced by more than seven average-sized American nuclear power plants. It could also save up to 50 percent of the $36.5 billion spent to power mobile base stations each year.

 

“Mobile operators gain dramatic advantages by adopting our new technology,” said Mattias Astrom, CEO of Eta Devices. “In addition to cost savings, our power amplifiers provide operators with a significantly reduced carbon footprint, which contributes to a more sustainable planet. In fact, if implemented on a global basis, our solution would reduce carbon emissions by approximately 36 million tons per year, which is equivalent to eliminating the annual greenhouse gas emissions produced by 7 million cars.”
 

Cree and Eta Devices’ demonstration of the new power amplifier will take place at the Barcelona Mandarin Oriental on February 26 from 1:00 p.m. to 5:00 p.m. For an invitation to attend the demonstration or to receive additional technical performance information, please e-mail greg@etadevices.com.

Feb 20, 2013

The New Industry Standard Brings Game-Changing Cost, Performance and Sustainability Advantages to Mobile Operators 

CAMBRIDGE, Mass, February 20, 2013 -- Eta Devices, Inc. is launching the world’s most efficient power amplifier for mobile base stations at the 2013 Mobile World Congress in Barcelona, Spain from February 24-28. 

“We are very pleased to introduce the world’s first power amplifier for mobile base stations achieving 70%+ efficiency for 4G LTE,” said Mattias Åström, CEO of Eta Devices. “In comparison, the best available competing solution, based on Doherty PAs, can only deliver up to 45% efficiency. This means that we bring a 50% increase in efficiency to the market and this is truly game-changing for the mobile industry.”
 

Eta Devices is a spin-off from the electrical engineering department at the Massachusetts Institute of Technology (MIT) and the new patented technology is known as Asymmetric Multilevel Outphasing (AMO). The 50% increase in efficiency by the firm’s AMO power amplifiers is made possible by a solution to the classic trade-off in mobile communications between efficiency and linearity.
 

“Eta Devices solution is a completely new architecture exploiting the extreme performance capabilities of GaN switching PAs” said MIT Prof. Joel Dawson, CTO of Eta Devices. “Implementing our technology in mobile base stations is analogous to replacing incandescent light bulbs with much more efficient LED lights. Most of the energy is now put to productive work instead of wasted as heat.”
 

On a global level, mobile networks consume approximately 120TWh of electricity per year – equal to two days of worldwide power consumption.-- with 50-80% of the power consumed by the base stations’ power amplifiers and associated components. Eta Devices’ solution has the potential to reduce power consumption by 50% which could save mobile operators around $18 billion per year in utility costs.
 

“Beyond generating cost savings and performance benefits for mobile operators, our technology makes a significant contribution to a more sustainable planet” said Åström, CEO of Eta Devices. “If Eta Devices’ solution is implemented by mobile operators around the world, we would see a reduction in greenhouse gas emissions of around 36 million tons carbon dioxide equivalents per year. This is as much CO2 as generated by 4.5 million American homes per year.”
 

The solution launched at the 2013 Mobile World Congress in Barcelona is focused on bringing disruptive benefits to the mobile base station market. Eta Devices is also in the process of developing a suite of low-power solutions for smartphones and tablet computers.
