The primary culprit in smartphone battery drain is an inefficient power amplifier a component that is designed to push the radio signal out through the phones antennas.
Prepared to send sizeable chunks of data at any given time the amplifiers stay at maximum voltage eating away power more than any other smartphone component and about 75 percent of electricity consumption in base stations#and wasting
and a shoebox-size module (for base stations) based on nearly a decade of MIT research to essentially switch gears to adjust voltage supply to power amplifiers as needed cutting the waste.
You can look at our technology as a high-speed gearbox that every few nanoseconds modulates the amount of power that the power amplifier draws from the battery explains Joel Dawson Eta Devices chief technology officer
If all midsized carrier networks were to replace current radio amplifiers with Eta Devices technology he says the reduction in greenhouse gases would be equivalent to taking about 5 million cars off the road.
The AMO technology was a new transmitter architecture where algorithms could choose from different voltages needed to transmit data in each power amplifier
which adjusts voltage to power amplifiers on the fly. But by adjusting that voltage continuously ET efficiency falls apart for 4G LTE
