Understanding the network energy efficiency challenge

At the end of last week, the GreenTouch telco energy-efficiency consortium told a presumably-glittering event in New York that its five-year project to design more energy-efficient telecommunications has been a success. In fact, the group said, it reckons that if adopted, its approaches could improve mobile network efficiency …

Google crafts neural network to watch over its data centers

Google has put its neural network technology to work on the dull but worthy problem of minimizing the power consumption of its gargantuan data centers. By doing this, the company says it has created a bit of software that lets it predict with 99.6 per cent accuracy how efficiently its data centers consume electricity, allowing …
