Indoor positioning using RF signals is usually a difficult task, due to multipath phenomena, that, especially for narrowband transmissions, can deeply affect signal propagation. In this paper, a simple technique for improving the accuracy of a received signal strength based ranging system is proposed. It is shown that, using narrowband low power transmissions in the 2.4 GHz channel and a multiple...
Wireless positioning systems are interesting for a variety of indoor applications such as security, home automation and ambient assisted living (AAL) services. Unfortunately, the accuracy of distance measurement techniques based on short-range wireless communication transceivers is generally quite poor, mainly because of multipath propagation phenomena. In this paper an analytical model describing...
