Wideband refers to a communication system that uses a broad range of frequencies to transmit data. This allows for higher data rates and improved performance compared to narrowband systems, which operate over a limited frequency range. Wideband technology is commonly used in various applications, including wireless communication, satellite communication, and broadband internet. In the context of audio, wideband can describe high-fidelity sound reproduction that captures a wider frequency range, resulting in clearer and more detailed audio. This is particularly important in telecommunications and broadcasting, where high-quality sound is essential for effective communication and entertainment.
