X-band communication refers to the use of radio frequencies in the X-band of the electromagnetic spectrum, which ranges from 8 to 12 gigahertz (GHz). This frequency range is commonly used for various communication and radar systems, including satellite communication, military radar systems, and weather radar systems. X-band communication offers high data transfer rates and is well-suited for applications that require high throughput and low latency. It is also less susceptible to interference and offers better signal quality compared to lower frequency bands. Overall, X-band communication is widely used in both civilian and military applications for its reliability and performance capabilities.
