Abstract: While mobile traffic is growing, the need for more sophisticated broadband services will push the limit on current standardization process. The main goal is to provide integration between wireless technologies and higher speeds, requiring a new generation of mobile communications-the fifth generation (5G). In contrast to the fourth generation (4G), 5G network should achieve 1000 times the system capacity, 10 times the spectral efficiency,higher data rates (for example, 10Gb/s for cell center users and 5Gb/s for cell edge users), 25 times the average cell throughput, 5 times reduction in end-to-end latency, and support 100 times more connected devices with 10 times longer battery life for low-power devices. The 5G infrastructure when defined as the ultra-broadband network enabling the future Internet, will be associated with the true revolution in the communication technology field.The network will take forward new services to everyone and everything, such as cognitive objects and cyber physical systems.New traffic types as well as data services are emerging, especially machine-to-machine communications to support some concepts such as the smart grid, smart homes and cities, e-health. These applications have very diverse communication requirements. The race to search for innovative solutions to enable 5G era has began worldwide. In early 2013, the European Commission announced that it would invest 50 million euros in 2013 for 5G research in multiple projects such as METIS, quickly followed by the formation of the Chinese Government-led IMT-2020 Promotion Group, in February 2013 and the initiation of the Korean Government-led 5G Forum, in May 2013. In Japan,the 2020 and Beyond Ad Hoc Group is under the Association of Radio Industries and Business (ARIB) advanced wireless communications study committee.In the United States, the three main activities on 5G era in Intel Strategic Research Alliance (ISRA), 4G Americas and NYU Wireless Research Center. At the moment, the standard bodies and idustry are dealing with a time frame to organize 5G technology, which is expected to be between 2016 and 2018, followed by initial deployment around 2020. This Plenary Lecture contains three parts. Starting with the description of the road to 5G , HetNet architecture evolution is pointed out. Macro and small cells may be connected to each other via backhaul resulting in different levels of coordination across the network for mobility and interference management. The second part deals with mobility for 5G network. The emphasis is on IP mobility management which is based on centralized data path. Next, the third part provides main drivers in the research for 5G application requirements including Internet of Things, Gigabit wireless connectivity and Tacktile Internet. Finally, standard activities conclude the presentation.
