ABSTRACT
Wireless data rates, which were around megabits per second or gigabits per second, are approaching terabits per second currently. Since THz technology has been achieving data speeds n times faster than expected, and as speeds are possible in terabits per second employing a single simple communication digital channel, applications including ultra-fast wireless connections are becoming possible. In the modern era of telecommunications, for wireless installations, it is fundamental to consider obstacles such as ceilings, walls, and even furniture that will affect the line of sight (LOS) and hence the reception of signals. In this context, the concept of LOS means there are no obstacles between the two antennas. In a “partial line of sight” (nLOS), there are partial obstacles such as a tree canopy between the two antennas. In addition, “non-line of sight” (NLOS) is characterized by a total obstruction between the two antennas. In this scenario, this chapter provides a discussion and overview of terahertz communication networks and propagation properties such as LOS, nLOS, and LOS, addressing their key points and their importance, with a related bibliographic information synthesizing the potential of technologies.
