“…GaN HEMT technology is promising for broadband wireless communication systems because of its high breakdown electric field and high saturation carrier velocity compared to other competing technologies such as GaAs and InP devices [60]. In fact, by utilizing a MMIC GaAs HEMT front-end, data rates up to 64 Gbps over 850 m [61] and 96 Gbps over 6 m [62] have been attained using a 240 GHz carrier frequency. In terms of InP-HEMT, improvement in electron-beam lithography is witnessing the increase in the speed of such devices as gate length decreases.…”

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. ).

“…120 GHz and 300 GHz and even the entire THz band [1]. With extreme antenna gains, a number of testbeds operating in the lower THz band have already demonstrated data rates on the order of tens of Gbit/s over hundreds of meters as in [2]. In indoor environments with mobility of users, realistically, the THz band is the most suitable for short link distances such as few meters.…”

The terahertz (THz) band, 0.1-10 THz, has sufficient resources not only to satisfy the 5G requirements of 10 Gbit/s peak data rate but to enable a number of tempting rate-greedy applications. However, the THz band brings novel challenges, never addressed at lower frequencies. Among others, the scattering of THz waves from any object, including walls and furniture, and ultra-wideband highly-directional links lead to fundamentally new propagation and interference structures. In this article, we review the recent progress in THz propagation modeling, antenna and testbed designs, and propose a step-bystep roadmap for wireless THz Ethernet extension for indoor environments. As a side effect, the described concept provides a second life to the currently underutilized Ethernet infrastructure by using it as a universally available backbone. By applying real THz band propagation, reflection, and scattering measurements as well as ray-tracing simulations of a typical office, we analyze two representative scenarios at 300 GHz and 1.25 THz frequencies illustrating that extremely high rates can be achieved with realistic system parameters at room scales.Index Terms-Terahertz band communications, beyond-5G networks, massive data offloading, last-meter connectivity, raybased modeling, THz band propagation measurements.

“…In [8], an InP DHBT fully integrated 300 GHz transceiver MMIC is presented. In previous work our group has demonstrated the transmission of 64 Gbit/s over 850 m [9] and 96 Gbit/s over 6 m [10] using a 240 GHz carrier frequency and an MMIC frontend based on GaAs metamorphic high electron mobility transistor (mHEMT) technology. Figure 1 illustrates the state of the art in submillimeter-wave wireless links, operating at or above a carrier frequency of 300 GHz, and employing both optoelectrical and pure electrical signal generation.…”

SUMMARYThis contribution presents a full MMIC chip set, transmit and receive RF frontend and data transmission experiments at a carrier frequency of 300 GHz and with data rates of up to 64 Gbit/s. The radio is dedicated to future high data rate indoor wireless communication, serving application scenarios such as smart offices, data centers and home theaters. The paper reviews the underlying high speed transistor and MMIC process, the performance of the quadrature transmitter and receiver, as well as the local oscillator generation by means of frequency multiplication. Initial transmission experiments in a single-input single-output setup and zero-IF transmit and receive scheme achieve up to 64 Gbit/s data rates with QPSK modulation. The paper discusses the current performance limitations of the RF frontend and will outline paths for improvements in view of achieving 100 Gbit/s capability.
