Convergence of Wireless and

The requirement of data increases many-fold in recent years to support the newest technologies in B5G and 6G. Wireless is the last mile solution as access with an optical network as the backbone in future communication systems. Over the years in every new generation, the distance between the base station and the user is decreasing and the optical node is coming closer to the user. There are several technologies like AR/VR, AI, holographic communication, holographic telepresence, etc. are the main candidates in B5G and 6G, which are required high-speed connection with low latency. To support these services, it is almost mandatory that transmit data across the network should be smooth and seamless to provide successful communication. Providing a successful and appropriate wireless link among the users simultaneously to achieve the requirements is becoming more complex, hence challenging. The optical backbone of all wireless access networks requires supporting these user's requirements, needs to evolve continuously with wireless network evolution. This chapter will study the evolution of both networks to understand

Over the year, the number of connected devices (wirelessly and wired) is everincreasing, will reach 13 billion by 2023 [1]. To support these always-connected devices, the demand for high speed, high reliability, low-latency, low-cost, dense connectivity, different types of mobility needs, and heterogeneous connectivity is escalating, which forced the telecommunications industry to enter into a new era of the future communication network (FCN) [2]. Furthermore, to unleash the full potential of Industry 4.0, guaranteed real-time communication between humans, robots, factory logistics, and products is a fundamental requirement [3]. The FCN incorporates 5G and beyond 5G network, whose main objectives will be application/service-oriented, which are on-demand and highly heterogeneous in nature [4]. To support ever-increasing devices for application-specific on-demand services, there is a strong requirement to view, design, and optimize the network
