The next generation wireless networks (NGWNs) are envisioned to adopt a wide variety of novel concepts and paradigm shifts that will play a major role in the deployment “5G and Beyond” and “Wireless 2.0” technologies. Massive Internet protocol (IP)–based connectivity including all of the cyber–physical systems equipped with wireless transmission and reception (a.k.a. Internet of everything (IoE)), ubiquitous and superior quality of experience (QoE), improved security, extremely–low latency, environment–friendly operation, extended coverage, capacity, and data rate with enhanced eﬃciency are only a few of the prominent characteristics of the NGWNs among many others. In parallel with these characteristics, the services to be provided widen in such a way that augmented reality, online gaming with extended dimensions, improved manufacturing processes, precision farming, fully autonomous transportation systems and many other applications are expected to be developed based on the envisioned capabilities of the NGWNs. It is obvious that such ambitious anticipations come at the expense of strict and very demanding technical requirements such as a high–degree of softwarization, extremely–ﬂexible architectures, seamless operations across ultra–dense heterogeneous networks with backward compatibility, optimized network access with sub–millisecond latencies, cross–layer adaptation and harmonization, high–degree of sustainability and reliability, increased security and extended privacy.
Even though each and every requirement item listed above constitutes a standalone and challenging research problem, ultra–dense heterogeneous networks with backward compatibility deserve a special attention since NGWNs must coexist with old as well as recently emerging technologies. Considering the cost of operation including deployment, maintenance, and optimization, an eﬃcient provisioning of fronthaul/backhaul communication systems and modules is required.
In this special issue, researchers from academia and engineers from industry are invited to contribute with their solutions to challenging problems raised by backhaul/fronthaul networking and communications for NGWNs. It is believed that technical contributions in this ﬁeld of research pave the way for “5G and Beyond” and “Wireless 2.0” by expediting the convergence of already existing networks and emerging ones. The scope of the special issue includes and is not limited to the following topics:
- Analysis of coexistence of multiple heterogeneous networks (cellular, WiFi, WiGig, etc.), associated problems and solutions;
- Investigation of the concurrence of diﬀerent cell sizes (macro, micro, pico, and femto) present in the same physical region;
- Exploration of multiple competitive high–data rate physical layer technologies such as free–space optics, visible light, terahertz, hybrid radio frequency (RF) communications;
- Incorporation of networked ﬂying platforms such as drones, balloons, unmanned air vehicles, and other high–altitude platforms into already existing infrastructures;
- Best practices from the industrial perspective and relevant challenges for fronthaul/backhaul communications in heterogeneous networks;
- Evaluation of security and privacy issues pertaining to fronthaul/backhaul communications links under constraints such as ultra–low latency and energy eﬃciency.
