Abstract
In recent years, the demand for wireless services and the number of mobile subscribers have seen tremendous growth. This growth motivated mobile operators and researchers to develop new transmission technologies, protocols and network infrastructure solutions to enhance the achievable throughput and the overall spectral efficiency. Future technologies include, (i) disruptive network designs including sensor networks, delay tolerant networks (DTN), vehicular networks, and cognitive networks, (ii) innovative signal processing algorithms at the physical layer as well as novel environment-aware applications, (iii) implementation of information theory aspects together with system design as, wireless network coding, physical-layer security, and interference alignment. Besides, the energy consumption of future wireless radio systems should be reduced, which creates inter-disciplinary research challenges including semiconductor technology, hardware, networks, services, and radio transmission. So far, wireless bandwidth has always lacked behind wired bandwidth. But the future is likely to make wireless the dominant medium for connectivity; not only will it be used for Internet access but also it will replace the piles of wires at home and in the office. The scarcity of the wireless spectrum is the main factor that limits the vision for wireless access everywhere anytime, and perhaps the toughest challenge that wireless research has to undertake. Overcoming this challenge requires innovations in various areas including novel ways for spectrum sensing and reuse, mechanisms for using higher frequencies such as 60 GHz and the visible light, novel ideas for dealing with interference, high-density MIMO, and generally more efficient protocols and systems. The talk will cover these technologies and will discuss their implementations in future 5G wireless systems. As well, existing technologies and their limitations in current standards will be discussed. Finally, future directions and research problems will be highlighted.
