The use of the optical spectrum for wireless communications has gained significant interest in recent years. Applications range from low-rate simplex transmission links using existing embedded CMOS cameras in smartphones, referred to as optical camera communications (OCC), mobile light fidelity (LiFi) networking in homes, offices, urban and sub-sea environments to free-space gigabit interconnects in data centers and point-to-point long-range wireless backhaul links outdoors and in space. This exciting book focuses on the use of optical wireless communications (OWC) for mobile use cases. The book discusses existing conventional radio frequency (RF)-based wireless access technology and presents the challenges that can impact the requirements of the future wave of new wireless services in the context of artificial intelligence (AI) driven autonomous systems and machine-type communications. The relationship between visible light communications (VLC) and light fidelity (LiFi), is explored, and the major advantages of VLC and LiFi such as security and data density, and discuss existing research challenges are also introduced. Channel modeling techniques are provided for mobile multiuser scenarios, and will introduce key building blocks to achieve LiFi cellular networks achieving orders of magnitude improvements of area spectral efficiency compared to state-of-the-art. Challenges that arise from moving from a static point-to-point visible light link to a LiFi network that is capable of serving hundreds of mobile and fixed nodes are discussed. An overview of recent standardization activities and the commercialization challenges of this disruptive technology is also provided.

This book explores Radio Access Networks (RANs) within LMR systems, comprising base stations, mobile radios, and hand portable radios. These components facilitate communication among end users via a network of fixed base stations, antennas, and combining systems strategically placed across radio repeater sites throughout the coverage area. This resource also delves into the consequences of interference, highlighting the painstaking efforts required to diagnose and rectify interference issues through field testing and redesign. The central focus being on the design intricacies of base station antennas and combining systems at densely populated shared radio repeater sites. The book underscores how to identify potential sources of interference from co-located transmitters and receivers, effectively surveying sites to anticipate high-level interfering signals. This critical information forms the foundation for crafting base station antenna and combining systems that curtail interference, subsequently optimizing coverage and minimizing costs. Throughout its pages, the book lays out a detailed roadmap for designing LMR systems resilient to interference. By outlining essential principles and methodologies, the book guides practitioners in creating LMR networks that flawlessly align with end users' communication requirements. The resulting systems not only meet expectations but surpass them, offering the coverage area and communication quality demanded by public safety and utility organizations during critical operations. Ultimately, the book serves as an indispensable resource for engineers, designers, and professionals engaged in crafting LMR systems capable of delivering impeccable performance and reliability.

This exciting new book examines the feasibility of using a method of doubling the capacity of cellular networks by simultaneously transmitting and receiving signals at the same frequency, a process known as full duplexing (FD). To realize full duplexing, changes in the hardware of the cell- base stations, relaying equipment, “hot spot” access points and mobile phones are necessary to prevent the hardware’s transmitters from interfering with their own receivers. This requires looking at how to separate the strong transmitted signal from the very weak received signal, a process requiring both hardware (analog) changes and more complex digital signal processing. Different ways of achieving that goal are examined. The books reviews the merits of hardware changes involving new duplexing components that may be different depending on the frequency band and cell hardware being used. Developing full duplex (FD) systems in 5G LTE cellular communications and what can be achieved with ferrite-based circulators in terms of size reduction and performance enhancement, especially at millimetric frequencies, is considered. The relative merits of ferrite and non-ferrite circulators are compared in terms of their fundamental materials and device technologies, such as isolation, insertion loss, bandwidth and non-linearity. FD in the entire 5G cell is also examined and its resulting range of equipment and device communication. This includes front-hauling, more sophisticated back and front-hauling, backhaul beam switching, and cell extenders and relays, all of which could involve FD.

This practical book is an accessible introduction to Orthogonal frequency-division multiplexing (OFDM) receiver design, a technology that allows digitized data to be carried by multiple carriers. It offers a detailed simulation study of an OFDM algorithm for Wi-Fi and 4G cellular that can be used to understand other OFDM waveforms. Extensive simulation studies are included using the transmissionwaveform given by the IEEE 802.11 standard. Scrambler, error-correcting codes, interleaver and radio-wave propagation model are included. OFDM waveform characteristics, signal acquisition, synchronization issues, channel estimation and tracking, hard and soft decision decoding are all covered. Detailed derivations leading to the final formula for any algorithm are given, which allows the reader to clearly understand the approximations and conditions behind the formulas and apply them appropriately. The algorithms are selected not just for the best performance from simulation study but also for easy implementation. An example is a unique algorithm for signal acquisition using the principle of maximum likelihood detection.
