Keynote
Abstract
5G mobile data communications deliver future information services spanning across enhanced mobile broadband services with massive connections, supporting ultra-reliable and low latency human and machine-type communications. 5G goes far beyond the definition of new radio access network with flexible function interfaces and expanded aggregation of multiple high- and low-frequency bands. 5G is about a new end-to-end network vision where integrated microwave photonics network elements and agile system function-slit usher in an integrated fiber-wireless access network infrastructure This flexible network support very diverse applications including broadband media distribution, Smart Cities, Internet of Things, and virtual and augmented reality. I will present an overview of the emerging standards and the ecosystems that are urgently driving the development of 5G wireless technologies and research topics that create opportunities for integrated microwave photonics devices and fiber-wireless optical access networks. I will discuss on the key roles that optics can play in the 5G vision, covering topics such as mobile X-backhaul, radio-over-fiber, advanced waveforms, and distributed cloud connect with smart edge nodes which are essential to deliver ultra-reliable low-latency services.
An all spectrum wireless communication network will be presented through seamless communications across all radio access technologies. All spectrum optical wireless module must be able to make massive network connections, by allocating channel frequency, switching MIMO to phased array antennas, and incorporate visible, infrared light and mm-wave communication channels. This all-inclusive network will have to meet technology challenges in three specific sectors: 1) spectral efficiency, 2) smooth migration path from low RF to millimeter wave and lightwave communications in heterogeneous network infrastructure. 3) Energy and form factor efficient modules that perform optical-millimeter wave generation, detection, coding and data recovery with hundreds gigabit/s transmission capability. It will pave the way for future network infrastructure to evolve to a semi-autonomous, adaptive, secure cyber physical communication platform.Short biography
