Terahertz (THz) Communication
Context:
A team of scientists has made a breakthrough in 6G communications by developing a new polarisation multiplexer, unlocking the potential of terahertz communications—the next frontier in wireless technology.
Terahertz (THz) Communication
It represents a promising frontier in wireless technology, operating within the frequency range of 0.1 to 10 terahertz.
This range offers significant advantages for high-speed data transmission, particularly as the demand for bandwidth continues to grow with the evolution of wireless networks towards 6G.
Key Features and Advantages
- High Bandwidth: The THz band offers vast, unallocated bandwidth—10 times that of the millimetre wave band and 100 times that of the SHF microwave band—enabling ultra-high data rates, potentially reaching terabits per second.
- Short-Range Communication: THz waves support extremely high-speed data transmission over short distances, making them ideal for localised applications like indoor environments.
- 6G Applications: THz communication will be crucial in 6G, supporting advanced applications such as high-definition holography, ultra-high-capacity wireless backhaul, and wireless networks on chips.
- Technology Integration: THz communications can integrate with sensing technologies, combining radar and communication functionalities to reduce latency and improve system efficiency.
Challenges
- Technical Limitations: High-frequency signals suffer from significant atmospheric losses, requiring advanced antennas and signal processing techniques.
- Component Availability: A lack of commercial components for THz frequencies hinders widespread adoption.
- System Design Complexity: Developing THz communication systems involves overcoming challenges like high-speed analog-to-digital conversion and managing ultra-wide bandwidth.
