ultra wide band - srihari - 08-16-2017 UWB is a wireless technology that transmits binary data the 0s and 1s that are the digital building blocks of modern information systems. It uses low-energy and extremely short duration (in the order of pico seconds) impulses or bursts of RF (radio frequency) energy over a wide spectrum of frequencies, to transmit data over short to medium distances, say about 15 100 m. It doesn t use carrier wave to transmit data. Current radio technology - picture a guy watering his lawn with a garden hose and moving the hose up and down in a smooth vertical motion.You can see a continuous stream of water. Nearly all radios, cell phones, wireless LANs and so on are like that: a continuous signal that s overlaid with information by using one of several modulation techniques. UWB technology - picture the same guy watering his lawn with a swiveling sprinkler that shoots many, fast, short pulses of water. That s typically what UWB is like: millions of very short, very fast, precisely timed bursts or pulses of energy, measured in nanoseconds and covering a very wide area. By varying the pulse timing according to a complex code, a pulse can represent either a zero or a one: the basis of digital communications. Advantages Current UWB devices can transmit data up to 100 Mbps, compared to the 1 Mbps of Bluetooth and the 11 Mbps of 802.11b. It s expected to reach around 500 Mbps by 2004. Also, this low power pulse can penetrate obstacles like doors, walls, metal etc. It doesn t require allocation of precious or paid for narrow-band spectrum, in use now. Best of all, it costs a fraction of current technologies like Blue-tooth, WLANs and Wi-Fi. UWB doesn t suffer from multi-path interference (where signals reach the receiver after traveling through two or more paths). Hence, it can be used in densely built-up places, or where number of users are more than what is supported by Wi-Fi, Blue-tooth etc.A UWB phone uses so little power that it can remain on for weeks without recharging. ultra wide band - sadik - 08-16-2017 to get information about the topic ultra wide band full report ppt and related topic refer the page link bellow http://seminarsprojects.net/Thread-ultra-wide-band-download-full-report-and-abstract http://seminarsprojects.net/Thread-ultra-wide-band-technology-full-report http://seminarsprojects.net/Thread-ultra-wide-band-technology-full-report?pid=42777 http://seminarsprojects.net/Thread-ultra-wide-band-small-details http://seminarsprojects.net/Thread-ultra-wide-band-full-report http://seminarsprojects.net/Thread-ultra-wide-band http://seminarsprojects.net/Thread-ultra-wide-band-download-full-report-and-abstract?pid=28793#pid28793 http://seminarsprojects.net/Thread-ultra-wideband ultra wide band - tyagi_57 - 08-16-2017 sir i need detail documentation about "ultra wide band" its very important and urgent as i have to submit in my college with in 2 days.please post the document to my email id: [email protected] ultra wide band - azar - 08-16-2017 please read http://seminarsprojects.net/Thread-ultra-wide-band-technology-full-report for getting more information about Ultra Wide Band |
