点击翻译按钮获取中文摘要

Wireless communications is a multibillion dollar international business and there are now a number of matureand emerging radio standards with readily available chipsets on the market such as WiFi, Ultra-Wide Band(UWB) and RFID. With these technologies new applications are starting to emerge. It is now possible to makeuse of wireless transceivers for localization and high precision position finding of objects in indoorenvironments. Intense research is beginning to make mapping of rooms with high precision using only a coupleof very low cost transceivers a reality. This could have many potential applications, including assisted livingfor people with vision impairments or elderly persons. It could also be used in warehouses to remotelydetermine the location of inventory in real time.
