It will also become the backbone of the Internet of Things (IoT), linking up fixed and mobile devices—vending machines and cars alike—becoming part of a new industrial and economic revolution, some say. A new architecture, new communication technologies, and new hardware will make this transformation possible. A research team comprising Zhiguo Ding at Lancaster University and researchers at China’s Southwest Jiaotong University have took stock of the recent research and future needs of 5G in a review last month in Science China [pdf]. In a Skype interview Ding spoke to Spectrum about his views on how 5G will take shape in the near future.
Spectrum: 4G is now being deployed in many countries, but is it already out of date? …[Read more]
