In this chapter, the key features of the emerging fifth generation (5G) wireless networks are highlighted briefly together with 5G architecture and the 5G radio access network (RAN), as specified by the standardisation bodies. The flexible nature of 5G networks and the anticipated 5G RAN design are introduced to be the enabling wireless edge for the Tactile Internet by providing ultra-reliable, ultra-responsive, and intelligent network connectivity. After discussing the architectural aspects and technical requirements of the Tactile Internet, the core design challenges are identified and some directions for addressing these design challenges are also provided. Ajoint coding method to the simultaneous transmission of data over multiple independent wireless links is presented in this context. Moreover, radio resource slicing and application-specific customisation techniques are introduced to enable the co-existence of different vertical applications along with Tactile Internet applications. Finally, edge-intelligence techniques are investigated to enable the perception of real time and to overcome the physical limitation due to the finite speed of light.
