Overview
ABSTRACT
This article presents the main elements of the wireless transmission systems in the (sub)terahertz (THz ) range. The main blocks of the physical layer of a transmission system are described and in particular specificities related to the THz range. Current results relating to technologies, transmission and reception are presented.
An overview of the actual transmission systems of prototypes and their system performance is presented, with current trends for future demonstrators.

Connecting mobile users ultra-fast is one of the great challenges of the 21st century. Wireless data networks are under enormous pressure to deliver the right amount of data to citizens, and conventional approaches are no longer sufficient. In today's hyper-connected world, digital information has to travel at ever-increasing speeds, from social networks to ultra-fast downloads.
The pressure of demand from nomadic users implies considerable growth in connectivity, density and volume of data traffic. Traffic densities of several Terabits per second/km 2 are predicted. These new uses, such as high-definition video streaming (4K), online gaming, augmented reality, soon to be autonomous vehicles, and real-time remote surgery, require the routing of masses of data, and entail ever-increasing data rates due to the immediacy of these uses.
Faced with this need for wireless connectivity, new approaches are urgently required. Technologies based on "Terahertz" waves, or "T" waves, can provide solutions. Since the early days of radio communications, the capacity of transmission links has constantly increased, and with the advent of packet mode transmissions of all types of data,...
