The demand for wireless wideband communications is rising as a result of the need to accommodate more users and deliver more data at faster data rates. Ultra-wideband (UWB) technology, which uses very brief pulses on the order of nanoseconds to cover a very large frequency spectrum, may be able to tackle this problem. UWB is a wireless technology with several potential applications that was created to transmit data at extremely high speeds over very short distances at very low power densities. This paper presents the UWB technology as it currently exists and its potential uses. The question of how to employ this technology without interfering with the current means of communication is also investigated. Comparisons with other wireless technologies highlight UWB's superiority in terms of accuracy, power consumption, and cost-effectiveness. The paper also explores modulation techniques and deployment scenarios, showcasing UWB's capability to revolutionize short-range communication networks and seamlessly integrate with existing wireless infrastructures.
