Back in June, I promised to spend some time this summer (and maybe even into the fall) talking about LTE TDD. That started with a discussion of how massive deployments in The People's Republic could lead one to think of LTE TDD as a Chinese technology, a notion that runs counter to any interests in seeing the LTE's TDD variant benefit from global manufacturing and R&D scale. A look back at the development of LTE standards, then, backed up the notion that, from its inception, TDD was envisioned as an integral part of LTE, not a narrow, regional use case.
We all knew the 5G pendulum was going to swing back pretty hard post-Mobile World Congress this year. Sure enough, come mid-year 2014, it's suddenly fashionable for people in the telecom industry (media, analysts, etc.) to push back on the 5G hype. You probably know the messages I'm thinking of: "There are still plenty of 2G networks supporting M2M and voice in operation." "3G will be with us for years, so keep investing in those networks." "LTE and LTE-A are more than capable enough to support millions upon millions of people watching million upon millions of streaming video sessions."
We've talked about Software Defined Networking (SDN) and Network Functions Virtualization (NFV) multiple times this year. While still relatively new concepts, there's general consensus that both have the potential to revolutionize the way in which we think about mobile networks and services: SDN thanks to driving service velocity and manageability, and NFV thanks to rethinking the platforms on which networks are built and how network capacity is (cost-effectively) turned up or torn down. To be sure, there are still plenty of questions around them.
We're all friends here, so we can be honest--right? Okay. In the broader tech world, telecom isn't always seen as the sexiest or coolest segment of the market.
