6G wireless communications: Propagation channel characteristics of terahertz band
Published: July 30, 2026
Abstract
The challenge of increasing communication traffic due to the massive exchange of information require revolutionary enhancement of data transmission rates in current and future wireless communication systems. The present deployed fifth-generation (5G) wireless technology in communications will find it difficult to satisfy the data rates and ultra-low latency requirements of these applications. These challenges are considered a critical driver toward the development of communication systems to a new era of wireless network, the sixth-generation (6G) wireless technology. THz communication technology is a key technology of 6G and has broad application prospects. Since wireless channels are the foundation for designing a wireless communication system in the new spectrum and new environments, it is imperative to study the THz radio propagation channels for 6G wireless technology in communications. This article reviews and analyzes key propagation characteristics of 6G wireless communications.
