Ultra-high bandwidth, negligible latency and seamless communication for devices and applications are envisioned as major milestones that will revolutionize the way by which societies create, distribute and consume information. The remarkable expansion of wireless data traffic that we are witnessing recently has advocated the investigation of suitable regimes in the radio spectrum to satisfy users' escalating requirements and allow the development and exploitation of both massive capacity and massive connectivity of heterogeneous infrastructures. To this end, the Terahertz (THz) frequency band (0.1-10 THz) has received noticeable attention in the research community as an ideal choice for scenarios involving high-speed transmission. Particularly, with the evolution of technologies and devices, advancements in THz communication is bridging the gap between the millimeter wave (mmW) and optical frequency ranges. Moreover, the IEEE 802.15 suite of standards has been issued to shape regulatory frameworks that will enable innovation and provide a complete solution that crosses between wired and wireless boundaries at 100 Gbps. Nonetheless, despite the expediting progress witnessed in THz wireless research, the THz band is still considered one of the least probed frequency bands. As such, in this work, we present an up-to-date review paper to analyze the fundamental elements and mechanisms associated with the THz system architecture. THz generation methods are first addressed by highlighting the recent progress in the electronics, photonics as well as plasmonics technology. To complement the devices, we introduce the recent channel models available for indoor, outdoor as well as nanoscale propagation at THz band frequencies. A comprehensive comparison is then presented between the THz wireless communication and its other contenders by treating in depth the limitations associated with each communication technology. In addition, several applications of THz wireless communication are discussed taking into account the various length scales at which such applications occur. Further, as standardization is a fundamental aspect in regulating wireless communication systems, we highlight the milestones achieved regarding THz standardization activities. Finally, a future outlook is provided by presenting and envisaging several potential use cases and attempts to guide the deployment of the THz frequency band and mitigate the challenges related to high frequency transmission. ).

“…The current literature on channel modeling in the THz band has been limited and restricted to indoor environments as we Photonics-based (Multi-band Channel) 300-500 GHz > 160 Gbit/s [19] still lack models that emulate outdoor environments. Basically, most models available in the literature can be categorized into either path loss or ray-tracing models.…”

Abstract-Over the past years, carrier frequencies used for wireless communications have been increasing to meet bandwidth requirements. The engineering community witnessed the development of wide radio bands such as the millimeter-wave (mmW) frequencies to fulfill the explosive growth of mobile data demand and pave the way towards 5G networks. Other research interests have been steered towards optical wireless communication to allow higher data rates, improve physical security and avoid electromagnetic interference. Nevertheless, a paradigm change in the electromagnetic wireless world has been witnessed with the exploitation of the Terahertz (THz) frequency band (0.1-10 THz). With the dawn of THz technology, which fills the gap between radio and optical frequency ranges, ultimate promise is expected for the next generation of wireless networks. In this paper, the light is shed on a number of opportunities associated with the deployment of the THz wireless links. These opportunities offer a plethora of applications to meet the future communication requirements and satisfy the ever increasing user demand of higher data rates.

“…To move beyond this, the THz band (300 GHz-10 THz) featuring an extremely large bandwidth available between the millimeter-wave and infrared radiation is considered as the "Next Frontier" to meet the data rate target of future UWNs. In the THz band, we have recently contributed to the development of THz wireless communication by demonstrating a series of high-speed photonic wireless transmission systems in the 0.3-0.5 THz regime with multi-channel Nyquist-quadrature phase shift keying (QPSK)/16 quadrature amplitude modulation (QAM) signals, [22]- [31]. These work is enabled by ultrafast THz transceivers, particularly the availability of ultra-broadband uni-travelling photodiodes (UTC-PDs) as efficient photo-mixing emitters and Schottky diodes as broadband electronic receivers, and the highest net data rate has reached up to 260 Gbit/s [31].…”

However, most of the demonstrations aforementioned are in view of the optical PDM, and/or the spatial MIMO and/or the frequency multiplexing techniques, all of which will in turn increase the system's size, energy consumption and the complexity in terms of both the hardware and the digital signal processing (DSP) module, resulting in increased overall cost.…”

Abstract-To accommodate the demand of exponentially increased global wireless data traffic, the prospective data rates for wireless communication in the market place will soon reach 100 Gbit/s and beyond. In the lab environment, wireless transmission throughput has been elevated to the level of over 100 Gbit/s attributed to the development of photonic-assisted millimeter wave (MMW) and THz technologies. However, most of recent demonstrations with over 100 Gbit/s data rates are based on spatial or frequency division multiplexing techniques, resulting in increased system's complexity and energy consumption. Here, we experimentally demonstrate a single channel 0.4 THz photonic-wireless link achieving a net data rate of beyond 100 Gbit/s by using a single pair of THz emitter and receiver, without employing any spatial/frequency division multiplexing techniques. The high throughput up to 106 Gbit/s within a single THz channel is enabled by combining spectrally efficient modulation format, ultra-broadband THz transceiver and advanced digital signal processing (DSP) routine. Besides that, our demonstration from system-wide implementation viewpoint also features high transmission stability, and hence shows its great potential to not only decrease the system's complexity, but also meet the requirements of prospective data rates for bandwidth-hungry short-range wireless applications.
