Managing 5G Networks - A Review of FSO Challenges and Solutions

摘要

The next generation of mobile network _ also known as 5G network, is targeted towards machine to machine connectivity and Internet of Things. In order to support IoT, 5G networks have to not only provide a higher bandwidth at access points but also support low latency. As the number of devices to be connected is very large, 5G is expected to be a an ultra dense network with a huge number of small cells facilitating connectivity to homes and vehicles as well as humans. This requires robust fronthaul and backhaul connectivity. This review paper explores the architecture evolving for 5G networks with a special focus on Free Space Optical links «FSO). It looks at the challenges in the FSO communications with a focus on weather and alignment parameters for 5G networks. The paper also explores solutions for overcoming these challenges and supporting IoT and machine to machine applications over 5G Networks.
