Abstract
The UWB is one wireless technology for indoor localization has been extensively researched in short range system because of its various applications. It can be used in firefighters tracking, logistics and military service. This system requires high accuracy in an indoor environment. In this paper evaluate and comparison between Trilateration and Min-Max localization techniques using received signal strength (RSS) and time of arrival (TOA) parameters. This study based on the ultra-wideband (UWB) transmission model for an indoor localization. The vector network analyzer (VNA) was used to measurement and recorders at FCC frequency band from 3.1 GHz to 10.6 GHz. Using the biconical antennas were used as both transmitter (Tx) and receiver (Rx) antennas. The accuracy and precision are also studies in the term of distance error. The cumulative distribution function (CDF) of distance error of each case is shown. From the results, the trilateration technique using TOA parameters very good accuracy.
