mmWave (millimeter wave) offers better transmission efficiency than traditional radio waves, providing higher resolution and lower latency. However, because mmWave signals have a shorter propagation distance in the air, more base stations are required to cover the same area. Below is a detailed introduction to the pros and cons of mmWave technology.

​

Advantages of mmWave

​

• Reduced Antenna Size:  mmWave features high frequencies and short wavelengths. This significantly reduces the size of the antennas, making devices more compact and lightweight.

• Minimized Signal Interference:  While mmWave signals weaken easily in the air and travel shorter distances, this characteristic reduces interference with other signals. It helps maintain stable communication quality, providing a cleaner, interference-free environment.

• High Speed and Low Latency:  As a key technology for 5G networks, mmWave delivers higher download and upload rates than 4G, alongside lower communication latency. This is crucial for real-time data transmission and rapid responses, such as in autonomous vehicles that require real-time data processing for environmental awareness and decision-making.

• High Connection Density and Large Capacity:  The short wavelengths of mmWave require a denser deployment of base stations. Consequently, 5G networks achieve higher connection density, supporting more devices connected to a single base station simultaneously for high-speed data transmission. This is essential for large-scale IoT devices, sensor networks, and VR/AR applications that handle massive amounts of graphics and video data.
