Which technology allows higher frequencies to be used in wireless communication?

Millimeter wave technology is specifically designed to operate at frequency ranges between 30 GHz to 300 GHz, which places it above microwave frequencies. This capability to utilize such high frequencies allows for a significant increase in the data transmission rates and bandwidth, enabling faster communication and more capacity for wireless systems. Millimeter waves also have short wavelengths, which can lead to smaller antennas and more compact devices, facilitating advanced applications in telecom, such as 5G networks.

While infrared systems and microwave systems do interact with higher frequency signals, they do not reach the extreme upper frequencies that millimeter wave technology can utilize. Satellite systems, although they serve long-range communication needs, generally use frequencies lower than those offered by millimeter wave technology for various practical streaming and transmission needs. Hence, millimeter wave technology stands out as the most effective in harnessing higher frequencies for wireless communication.
