In his keynote at this year’s GSMA Mobile World Congress, ARM CEO Warren East outlined the need to make mobile networks smarter by incorporating technology developed for mobile devices. “The ARM view is that these smarter networks can be enabled through smarter system design. It’s about bringing the rich ecosystem of software, applications and tools that has grown up around the mobile handset space and deploying that, re-using it effectively, in the network infrastructure,” he said. East said operators can’t just keep installing capacity to keep up with demand as they need to control both costs and energy use: “Energy is a really big component of the cost and a really big limiting factor for the greater expansion of these networks.”
