Wireless mesh networks (WMNs) are wireless communication networks organized in a mesh topology with radio capabilities. These networks can self-form and self-heal and are not restricted to a specific technology or communication protocol. They provide flexible yet reliable connectivity that cellular networks cannot deliver. Thanks to technological advances in machine learning, software defined radio, UAV/UGV, big data, IoT and smart cities, wireless mesh networks have found much renewed interest for communication network applications.

The latest advances in several emerging technologies such as AI, blockchain, privacy-preserving algorithms used in localization and positioning systems, cloud computing and computer vision all have great potential in facilitating social distancing. Benefits range from supporting people to work from home to monitoring micro- and macro- movements such as contact tracing apps using Bluetooth, tracking the movement and transportation level of a city and wireless positioning systems to help people keep a safe distance by alerting them when they are too close to each other or to avoid...

Recent technological advances have made possible the creation of a chain of non-geostationary satellite orbit (NGSO) communications systems. Such systems offer the advantages of ubiquity, relatively low costs, and upgradable infrastructure that enables the use of innovative on-board technologies. This evolution opens up a plethora of opportunities for massive self-organized, reconfigurable and resilient NGSO constellations, which can operate as a global network.

Ambitious low-orbit constellation types are currently being developed, motivated by advanced communication technologies and...

In the race against climate change, the focus has turned towards achieving the 2050 net-zero carbon target. Achieving net-zero means balancing between the amount of greenhouse gas removed from the atmosphere and those produced and released. Efforts are needed on both sides to find suitable solutions to reduce released emissions and to remove current emissions from the atmosphere. A collective effort revolving around the utilisation of new technologies, particularly in wireless and mobile communications, is needed to achieve the net-zero carbon target.

The previous generations of...

6G networks are expected to provide one-microsecond latency communication with a billion devices competing for resources 1000 times faster than current standards. Increases in network speed, heterogeneity, virtualization, better radio requirements and adaptive communications will place new demands on physical layer security. Moreover, IoT, blockchain, and artificial intelligence are enabling technologies that require rapid data rates, raising a significant burden on the network's physical layer, requiring that security must be attained at a fast pace, and that the network must be resilient...

Being surface-mounted and chip-like in nature, the antenna booster fits seamlessly in an electronic printed circuit board the same way as any other electronic component such as an amplifier, filter or switch. It can be assembled with a conventional pick-and-place machine, making the manufacture and design of the new generation of IoT and mobile or wireless devices much simpler, faster and more effective.

Starting with the theory and fundamentals behind the design of antenna boosters and matching networks, the authors present several architectures and show the readers how to put the...

Digital twin (DT) technology is a real-time evolving digital duplicate of a physical object or process that contains all its history. It is enabled by massive real-time multi-source data collection and analysis. While 6G is considered as an enabler of digital twins, DT can also be a facilitator for integrating AI and 6G towards reliable, pervasive and efficient intelligent technologies.

While the DT concept is familiar among aerospace and industrial engineers, it is a relatively new topic among electronic, electrical, computer, communications and networking engineers. For future...

There are numerous potential paths toward achieving the 6G network and various factors that could define it. Written by three telecom industry experts, this book explores the opportunities and challenges surrounding the next generation of wireless communication technology. Will 6G build solely on the future evolution success of the 5G network, or will the delivery of 6G facilitate a revolution in technology and infrastructure with the convergence of fixed/mobile networks and collaboration with hyperscalers to help fund it?

The book presents a compelling vision of how 6G addresses the...

Reconfigurable intelligent surface (RIS) has emerged as a cutting-edge technology for beyond 5G and 6G networks due to its low-cost hardware production, nearly passive nature, easy deployment, communication without new waves, and energy-saving benefits. Unmanned aerial vehicle (UAV)-assisted wireless networks significantly enhance network coverage.

Resource allocation and real-time decision-making optimisation play a pivotal role in approaching the optimal performance in UAV- and RIS-aided wireless communications. But the existing contributions typically assume having a static...

Billions of wireless applications are proliferating in the global space. The novel wireless systems to support these applications need to satisfy several user-defined metrics to ensure quality of physical experience, quality of service, low latency and ultra-high reliability. Enabling technologies are being developed in order to meet these rate-hungry requirements.

Managing these complex wireless and computing resources requires a proactive analysis of the core wireless systems, especially in the metaverse, which is a virtual model of the physical world systems. The metaverse concept...
