Terahertz Communication



                  Electronics and Communication Engineering (ECE) in Terahertz CommunicationTerahertz (THz) communication is a cutting-edge technology that operates in the terahertz frequency band (0.1–10 THz), positioned between microwave and infrared wavelengths. This frequency range offers unparalleled opportunities for ultra-high-speed wireless communication, making it a key enabler for next-generation networks like 6G and beyond.
 
 


What is Terahertz Communication


Frequency Spectrum
  • Terahertz waves are electromagnetic waves with frequencies between 100 GHz and 10 THz.
High Data Rates
  • Capable of delivering data rates in the range of Tbps (terabits per second) due to its large available bandwidth.
Applications
  • Suitable for applications requiring high-speed data transmission, such as augmented reality (AR), virtual reality (VR), high-definition video streaming, and inter-satellite communication.
Short Range
  • Due to higher frequencies, THz signals have a short propagation range and are highly susceptible to atmospheric attenuation.
