ABSTRACT
Imagine a world where homes, cars, offices, and many other environments will be intelligent. These environments will be able to sense objects and the presence of people in order to perform many different functions, including adjusting the environment to suit the individual based on the time of day or day of the week, monitoring the elderly or children for health and safety purposes, or performing security functions, just to name a few. There stood a revolutionary wireless technology that has the potential to address each of above technical challenges and its none other than “Ultra Wide Band.”Ultra-Wideband (UWB) can be best defined as any short-range radio technology having bandwidth exceeding the lesser of 500 MHz or 20% of the arithmetic center frequency, according to Federal Communications Commission (FCC). UWB is a new radio technology that promises to revolutionize high-speed data transfers and enable the personal area networking (PAN) industry leading to new innovations and greater quality of services to the end user.
UWB allows high data throughput with low power consumption for distances of less than 10 meters at an impressive rate of 480 Mbps is expected to be shown in the not-too-distant future. To satisfy the demand for high data wireless communication along with good Quality of Service, one of the promising technologies is Multiple Input Multiple Output wireless technology. This paper describes the time and frequency domain description that demonstrates the basic principle of the UWB. The UWB spectrum shows the frequency and emitted signal power variation for Ultra Wideband along with the other wireless technologies. The comparison chart reveals the high data rate of UWB compared with the existing technologies like that of Bluetooth. UWB capabilities like its ranging, advancement over the Wi-Fi and the reduction of Power Drain with the help of Bluetooth has been discussed. With its unlimited and unmatched capabilities there are many UWB applications that are being investigated or implemented. Some of the many promising technologies discussed in this paper are Super caddie, military, healthcare, ultra-vision security, low power sensors, process energy, supply chain, high speed Bluetooth etc are discussed in this paper.
Ultra Wideband radio or UWB was an obscure concept in the last century, but will become part of everyday life in the current century. Just as the automobile and electricity were important innovative forces in the early part of the 20th century, wireless digital communications is the next big thing. The recent spurt of investigations, investments, and regulatory rulings indicate an exploding interest in Ultra Wideband technology. The technology must overcome concerns about interference with safety-of-life signals before achieving complete acceptance. Successful operation without interference will certainly lead to numerous anticipated applications and an entirely new face of Wireless communication.
