Abstract
This paper studies ultra wideband (UWB) and narrow band (NB) propagation in the frequency range of 3 GHz to 11 GHz. The UWB signal was used to follow the standard of IEEE802.15.4a in order to find the position in line of sight (LOS) and non-line of sight (NLOS) environment. Then, the sinusoidal frequency was tested in the frequency range of 3 GHz to 11 GHz, changing 1 GHz per step in order to analyze and compare with the UWB standard. The experiments were done by using vector network analyzer (VNA). Four conditions were studied in LOS and NLOS environment for indoor positioning. The four condition are the parameters; UWB standard; polarizations; and the frequencies. For the positioning determination, a location pattern technique was used with a minimum root mean square (RMS) error matching algorithm to find the position. Finally, a suitable condition is shown, and it has an accuracy of 91.11% at 1 meter.
