Abstract
Wireless sensor networks (WSNs) have been applied in various applications. Each application is developed in order to increase security, increase convenience to life and property. In this work, we have analyzed the application of WSNs to locate with fingerprinting technique on the standard of IEEE802.15.4a (Ultra wideband (UWB)) in terms of the number of antennas required when using line of sight (LOS) environment. The experiment was done by using a vector network analyzer (VNA) with biconical antennas. The frequency transfer function of the channel was measured at various locations. As a result, the use of delay time parameter of the UWB standard gave the best result. It was able to use only one antenna pair to identify areas accurately. Moreover, it saved time for doing the database, reduced size of the database and reduced some cost because the number of antennas was decreased.
