Real-time location systems (RTLS) for persons and objects are gaining high interest for consumer and industrial applications. Information about position allows the creation of intelligent context, which enables a great variety of value-added or even new services. There is no one localization technology that fits all application scenarios. But the unique aspects of ultra-wide band (UWB) make it a very promising technology to realize diverse kinds of ranging and positioning systems, especially in the very harsh industrial environments. In this paper, a research project on 3D positioning using UWB technology is presented along with the project objectives and expected outcomes. The project is funded by the National Science, Technology and Innovation Plan (NSTIP) in Saudi Arabia, and is being performed at Umm Al-Qura University. The research work contributes to the field of wireless communications and wireless sensor networks (WCWSN), which is an initiative of the narrowed focus of the Electronics, Communications and Photonics (ECP) program that was selected based on the specific needs and objectives of Saudi Arabia and was also included in the research priorities of the NPSTI. The major aspects of the ECP program in addition to description of achieved project work are provided.
