Book Description
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.

Book Description
5G and Satellite RF and Optical Integration, the latest ‘hot off the shelf’ groundbreaking book from Artech House authored by subject specialist Geoff Varrall is packed with essential time critical information. This updated edition has everything needed to know in order to understand the new world of terrestrial and non-terrestrial telecom technology. It analyzes the radio spectrum/band and technical specifications under consideration for 5G, along with the related performance, cost, and vertical market expectations. In addition, the book studies the cost of coexistence between 5G operators and other user communities' co-sharing spectrum, including GNSS; radio astronomers; radar; GSO, MEO, and LEO satellites in the Ku, K, and Ka bands and above; and satellite TV. Also covered is the role of free-space optical technology in 5G and satellite networks and what interference issues will arise from new band allocations. This includes co-shared allocations and how interference will be mitigated in and between next generation terrestrial and satellite 5G networks. The publication coincides with an inflection point where terrestrial, nonterrestrial, and RF and optical networks could be integrated in a financially useful way.

Book Description
With more than 15 billion Wi-Fi enabled devices, Wi-Fi has proven itself as a technology that has successfully evolved over the past 25 years. The need for high-speed connectivity is growing, as Wi-Fi has evolved into a fundamental utility that is expected to be available everywhere. This comprehensive resource covers six generations of Wi-Fi standards including protocol, implementation, and network deployment for both residential and enterprise environments. It will provide readers with a new understanding of how to approach and debug basic Wi-Fi problems, and will grant those wondering whether to pick 5G or Wi-Fi 6 for their product the clarity needed to make an informed decision. Readers will find in-depth coverage of Wi-Fi encryption and authentication methods, including explorations of recently uncovered security vulnerabilities and how to fix them. This book also provides detailed information on the implementation of Wi-Fi, including common regulatory and certification requirements, as well its associated challenges. This book also provides direction on the placement of Wi-Fi access points in indoor locations. It introduces the most recent Wi-Fi 6E certification, which defines requirements for devices operating on the newly opened 6 GHz band. Wi-Fi 6 is then compared with 5G technology, and this resource provides insight into the benefits of each as well as how these two technologies can be used to complement each other.

Book Description
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.

It provides an overview of all the positioning technologies used in cellular networks, from GSM to 5G, from RAT independent technologies, such as A-GNSS (including GNSS evolution, RTK and PPP), WiFi, Bluetooth and sensor fusion, to cellular network native technologies, such as OTDOA / DL-TDOA, ECID, multi-cell RTT and the Angle Of Arrival (AOA) based techniques that take advantage of 5G mmWave beamforming features. Different positioning protocols, especially the LTE Positioning Protocol (LPP), which is used for LTE and 5G NR and defines the communication between the user device (mobile phone, connected vehicle, etc.) and the base station are explained extensively, and compares it with other competing protocols such as OMA LPPE. Furthermore, it also explains the core network positioning protocols (LPPa, NRPPa), that describe the communication between the location server and the core network. Explanation of different signaling parameters will enable the reader to understand better how positioning works in a cellular network.
