Millimeter wave communication is a research area that focuses on the use of high-frequency electromagnetic waves in the millimeter wave spectrum (30 GHz to 300 GHz) for wireless communication. These frequencies offer high data rates and low latency, making them ideal for high-speed communication applications such as 5G networks, mmWave radar systems, and point-to-point communication links. Researchers in this field are working to develop advanced antenna technologies, signal processing techniques, and communication protocols to overcome the challenges associated with millimeter wave transmission, such as signal attenuation due to atmospheric absorption and foliage, and limited range and penetration through obstacles. Additionally, efforts are being made to standardize millimeter wave communication technologies to enable interoperability and widespread adoption across different devices and networks.
