– Researchers have developed a new silicon chip that can steer terahertz waves using a topological beamforming technique. Terahertz frequencies show promise for ultra-fast 6G wireless networks.
– The chip takes a single terahertz input signal and splits it into 54 smaller beams that are guided through tiny channels and turns. Each beam can transmit data at speeds of 40-72 gigabits per second, far surpassing current 5G speeds.
– By using an artificial intelligence designed honeycomb pattern, the chip forms lanes that send powerful, focused beams in all directions around it (360 degrees). This allows any nearby device to receive the high-speed signal.
– Terahertz frequencies have shorter range but beamforming helps direct the signals precisely to maintain quality over long distances. This improves network efficiency, reliability, and capacity as more devices connect.
– Potential applications include 4K movie downloads in seconds over WiFi, high-quality virtual/augmented reality, real-time holograms, and smart city/health services like remote surgery. The chip is an important step towards ultra-fast, reliable 6G wireless networks.
