Abstract

The advent of future 5th Generation (5G) use cases, such as ultra-dense networking and ultra-low latency propelled by Smart Cities and IoT projects will demand revolution- ary network infrastructures. The need for low latency, high bandwidth, scalability, ubiquitous access and support for IoT resource-constrained devices are some of the prominent issues that networks have to face to support future 5G use cases, which arise since current wireless and mobile infrastructures are not able to fulfill. In particular, the pervasiveness and high-density of Wireless Local Area Networks (WLAN) at urban centers, together with their growing capacity and evolving standards, can be leveraged to support such demand. We argue that the integration of key 5G cornerstone technologies, such as Network Function Virtualization (NFV) and softwarization, fill some of the abovementioned gaps in regards to proper WLAN management and service orchestration. In this paper, we present a solution for slicing WLAN infrastructures, aiming to provide differentiated services on top of the same substrate through customized, isolated and independent digital building blocks. Through this proposal, we aim at efficiently handling ultra-dense networking 5G use cases to achieve benefits at unprecedented levels. Towards this goal, we present proof of concept realised over a real testbed and assess its feasibility.
