     This book discusses the smooth integration of optical and RF networks in 5G and beyond 5G heterogeneous networks HetNets covering both planning and operational aspects The integration of high frequency air interfaces into 5G wireless networks can relieve the congested radio frequency RF bands Visible light communication VLC is w emerging as a promising candidate for future generations of HetNets Heterogeneous RF optical networks combine the high throughput of visible light and the high reliability of RF However when implementing these HetNets in mobile scenarios several challenges arise from both planning and operational perspectives Since the mmWave terahertz and visible light bands share similar wave propagation characteristics the concepts presented here can be broadly applied in all such bands To facilitate the planning of RF optical HetNets the authors present an algorithm that specifies the joint optimal densities of the base stations by drawing on stochastic geometry in order to satisfy the users quality of service QoS demands with minimum network power consumption From an operational perspective the book explores vertical handovers and multi homing using a cooperative framework For vertical handovers it employs a data driven approach based on deep neural networks to predict abrupt optical outages and on the basis of this prediction proposes a reinforcement learning strategy that ensures minimal network latency during handovers In terms of multi homing support the authors examine the aggregation of the resources from both optical and RF networks adopting a two timescale multi agent reinforcement learning strategy for optimal power allocation Presenting comprehensive planning and operational strategies the book allows readers togain an in depth grasp of how to integrate future coexisting networks at high frequency bands in a cooperative manner yielding reliable and high speed 5G HetNets
