ETSI Gets Edgy About Mobile

Iain Morris

Lucky enough to be at Wimbledon's world-famous tennis venue in July, you are left slack-jawed in disbelief after Britain's Andy Murray, playing Canadian marksman Milos Raonic in the men's singles final, successfully returns a 147mph serve -- the second fastest in the tournament's history -- and then wins the point. Whipping out your smartphone, you watch an instant replay that confirms the athletic feat, in high-definition glory, before the next rally has even begun.

Such zippy localized service offerings have long been a talking point in telecom. Thanks to emerging technologies, they might soon become a lot easier to provide. By taking the compute-and-storage capabilities at the core of a mobile network and deploying them much closer to the end user, at the network's "edge," operators could boost performance to a new level. Instead of bouncing traffic on a costly, time-consuming journey to the core and back again, they could do all their processing in a flash at the venue itself. It would be like turning a looping tennis serve into a Raonic rocket.

It's a Cloudy Vision at the Edge
Service providers are pondering how mobile edge computing fits into a  distributed cloud strategy.

Since March last year, the European Telecommunications Standards Institute (ETSI) has been working on the technical specifications for mobile edge computing (MEC), as it has become known. The stakes are getting higher. In the fast-growing market for cloud services, operators with edge infrastructure could boast a decisive performance-related advantage over cloud providers that rely on centralized resources, according to Gabriel Brown, a senior analyst at the Heavy Reading market research unit. "Theoretically, they could start hosting other people's services and content," he says. "It will be hard for providers without edge infrastructure to compete."

False dawns
Yet despite all the promise, mobile edge computing has had a number of false dawns. As a concept, it has been around since the heyday of 3G, when the idea of using edge infrastructure to support mobile video traffic first took hold. Since then, it has been pummeled by a series of challenges, obstinately refusing to be knocked down. "The principle is sound and solid," says Brown. "The practical application has been a bit elusive."

Economics may have wrong-footed the technology in the early days. The original view was that compute-and-storage resources would be deployed only at the mobile basestation. That would have meant installing servers at many different sites, driving up costs substantially. Usage patterns also meant the benefits of this approach may have been hard to realize. "How many people have wanted to watch the same YouTube video at the same time in the same cell?" says Brown. "That 'cache ratio' has been too low."

Security could be a further headache were servers to be rolled out this way and user information stored at some distance from a safe zone. "A basestation might be in a farmer's field, where there is a possibility it gets physically intercepted," says Adrian Neal, the vice chair of ETSI's industry specification group (ISG) for mobile edge computing and a standards team leader at Vodafone Group plc (NYSE: VOD), one of the world's biggest mobile operators. "The way around that is to increase the physical security of basestations, but that comes with cost."

Lots of questions for this week's MEC conference in Munich
Scope for lots of interesting discussion at this week's Mobile Edge Computing congress in Munich. The obvious questions for Deutsche Telekom and Ericsson are where they see most of the standardization efforts coming from, in the edge computing area, if not ETSI.

Light Reading will be covering this event so if there are any burning issues you think we should raise please shout in the message boards.

Understanding the full experience of women in technology requires starting at the collegiate level (or sooner) and studying the technologies women are involved with, company cultures they're part of and personal experiences of individuals.

During this WiC radio show, we will talk with Nicole Engelbert, the director of Research & Analysis for Ovum Technology and a 23-year telecom industry veteran, about her experiences and perspectives on women in tech. Engelbert covers infrastructure, applications and industries for Ovum, but she is also involved in the research firm's higher education team and has helped colleges and universities globally leverage technology as a strategy for improving recruitment, retention and graduation performance.

She will share her unique insight into the collegiate level, where women pursuing engineering and STEM-related degrees is dwindling. Engelbert will also reveal new, original Ovum research on the topics of artificial intelligence, the Internet of Things, security and augmented reality, as well as discuss what each of those technologies might mean for women in our field. As always, we'll also leave plenty of time to answer all your questions live on the air and chat board.
