What is mmWave (Millimeter Wave)?

mmWave (Millimeter Wave) refers to high-frequency radio waves in the 24 GHz to 100 GHz range, used primarily for 5G networks, high-speed wireless communication, and advanced radar systems. It enables ultra-fast data speeds (up to 10 Gbps) and extremely low latency, making it ideal for applications like smart cities, autonomous vehicles, and augmented reality (AR/VR). However, mmWave signals have a shorter range and struggle to penetrate buildings, requiring small cells and dense network deployments to ensure reliable coverage.
