When I was a kid, spying was something countries did to maintain the upper hand in war, trade negotiations, bragging rights and financial gain. The tools of the spy trade included listening/recording devices, super telephoto lenses, a submarine, a stylish and aloof international man or woman and, most importantly, a very fast car, plane or speed boat. At least, that’s what the James Bond movies led us all to believe ...

At the recent Mobile World Congress, I heard many operators express an interest in analytics. They could see its potential to enrich customers’ user experience and offer new services. Many seemed to grasp how the basis for innovative services customized to user interest and user preferences can be built by correlating data from service connectivity, application types, service context, and performance metrics among others. Such data can also be used to identify malicious attacks on a network or on individual users, giving operators the chance to initiate counter action, preventing damage and mitigating the impact ...

Well, with the disclaimer that one predicts the future at his own peril, there are 5 major trends that I think show signs of being huge for DCI in 2016: 1. Power Efficiency Will Continue to Dominate - Power efficiency has always been important to DCI and it will stay on the agenda in 2016.

They are literally building underfilled warehouses in the hopes that future power efficiency gains will allow them to fill them to capacity ...
