Beamforming
Beamforming is a technology that helps improve wireless communication by directing radio signals like a focused spotlight instead of broadcasting them in all directions like a light bulb. It's commonly used in modern wireless networks (5G, WiFi) and mobile communications. Think of it as a smart antenna system that can point the signal directly at users' devices, which helps provide better coverage, faster speeds, and more reliable connections. This technology is becoming increasingly important as companies build new cellular networks and improve wireless systems.
