5G Network Architectures: From X-haul Transport to Multi-Layer Service Slicing

5G introduces new network architectures and service requirements that will have major implications for how operators design transport networks. As communication service providers (CSPs) are in the early stages of rolling out 5G, Mobile World Live conducted an online survey of mobile and fixed-line network operators and mobile virtual network operators (MVNOs) to understand current strategies for 5G transport networks. The survey revealed that resolving 5G transport issues is a high priority for CSPs and showed that while CSPs are initially concerned with meeting capacity and low latency requirements in the near term, they are also preparing to support advanced 5G features such as X-haul, network slicing and Multi-access Edge Computing (MEC).
