SNOB-5G : Scalable Network Backhauling for 5G
Upcoming 5G networks demand massive and dense rollout of Small Cells in urban environments to meet the challenging bandwidth, capacity and latency requirements of new and innovative services in order to do so efficiently, and in a cost-effective manner, Operators and Tower Companies must take advantage of new technology, to assure fronthaul and backhaul requirements. The latter, specifically, impose new challenges in network planning as optical fiber, the preferred medium, may not always be available and its deployment costs may deem such installations unfeasible.
Given the importance of 5G networks, it is clear that its implantation and expansion, should not be held hostage by the availability of wired connections to support backhaul communication Wireless links are commonly used in fixed network topologies; however, its throughput may not always be enough for envisioned 5G networks and services.
To overcome these bottlenecks, and build a high-bandwidth wireless backhaul between 5G radio units, work has to be carried at different software levels by introducing AI into such systems, they can be fully autonomous and work in a mesh topology, connecting to others in the vicinity, if a specific wireless link does not provide the required QoS, or has even been shut down for unknown reasons. This would allow for the design of a truly highly resilient and fault-tolerance network with no single point of failure.
Given the volatility of such links, the backhaul network should be autonomous, self-organized and resilient enough to support critical features of 5G such as edge-based and SDN with excellent levels of security and privacy.
