New method extends practical range of high-frequency wireless beam control

Princeton University researchers have found a way to extend the near-field range for sub-terahertz wireless systems using off-the-shelf hardware. By using multiple synchronized arrays, the team achieved advanced near-field capabilities that were previously thought to require much larger and more expensive systems. Technologies using this high-frequency radio spectrum promise to unlock extraordinary data rates and entirely new sensing and security capabilities for telecommunications and defense applications.
