Wireless Technology for High-Accuracy Localization

无线通信是一项价值数十亿美元的国际业务，现在市场上有许多成熟和新兴的无线电标准，如WiFi、超宽带（UWB）和RFID。随着这些技术的发展，新的应用开始出现。现在可以利用无线收发器对室内环境中的物体进行定位和高精度定位。密集的研究开始使测绘房间的高精度只使用一对夫妇的非常低成本的收发器成为现实。这可能有许多潜在的应用，包括视力障碍者或老年人的辅助生活。它也可以用在仓库中，以远程确定库存的位置在真实的时间。

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.
