Abstract
As a radically distinct wireless communication approach compared to traditional narrow band systems, ULTRA-WIDE BAND (UWB) technology has been applied in various sectors and is gaining in popularity, but there appears to be a lack of systematic summary of the potential of this technology. To provide insights into UWB technology for the uninitiated reader, this paper explores the state-of-the-art research and development of UWB applications in many sectors including the construction industry without concerning the technological details. First this paper presents the key concepts related to UWB technology and a brief history of UWB. Then it summarizes the UWB's technical features which enable its popularity in industry. Finally, application examples of UWB technology in many sectors, including construction, are presented to analyze and highlight the impact on the industry performance. In the near future UWB technology is expected to become a very important component and have far-reaching impact in ubiquitous computing. Santrauka Bevielio ryšio ultraplačios juostos bangų (UWB) technologija, radikaliai besiskirianti nuo tradicinės siauros juostos sistemų, buvo plačiai taikoma įvairiuose sektoriuose ir tampa vis populiaresnė, tačiau akivaizdu, kad vis dar trūksta susistemintos šios technologijos galimybių apžvalgos. Siekiant pateikti įžvalgas apie UWB technologiją, šiame straipsnyje analizuojami dabartiniai UWB technologijos tyrimai ir UWB taikymas įvairiuose sektoriuose, įskaitant statybą, nenagrinėjant technologinių detalių. Pirmiausia šiame straipsnyje pristatomos pagrindinės sąvokos, susijusios su UWB technologija ir UWB technologijos istorine raida. Tada susisteminamos techninės UWB technologijos charakteristikos, kurios lemia jos populiarumą pramonėje. Galiausiai analizuojami UWB technologijos taikymo pavyzdžiai įvairiuose sektoriuose, įskaitant statybą, atkreipiant dėmesį į jų poveikį pramonės veiklai. Netolimoje ateityje UWB technologija turėtų tapti labai svarbi ir turėti ilgalaikį poveikį visuotinei kompiuterizacijai.
Highlights
In recent years, the increasing need to know the location of resources, such as people, equipment and materials, in real-time has been rapidly expanding in a variety of industries
Some emerging radio frequency (RF)-based technologies have been proposed to facilitate resource tracking, for example, pipe spools and structural steel members tracking by Radio-frequency identification (RFID) (Domdouzis et al 2007), vehicle tracking and collision detection using global positioning system (GPS) (Oloufa et al 2003), automated material tracking based on ZigBee localization technology (Jang and Skibniewski 2007)
As for construction industry, ULTRA-WIDE BAND (UWB) is used for automated real-time three-dimensional location sensing for construction resource, on-site real-time safety management, robot positioning system, emergency application, localization in mining environments, nondestructive evaluation of pavements and railroad track substructure
Summary
The increasing need to know the location of resources, such as people, equipment and materials, in real-time has been rapidly expanding in a variety of industries. Due to its short pulse radio frequency (RF) waveforms and large bandwidth, UWB provides fine time resolution and provides good potential for application in ranging and positioning and well immunity to multipath effects.
