    In this paper, the accuracy analysis of indoor positioning using min-max method is proposed. The distance error model is applied to estimate the distance between the transmitter and user's position with different path loss exponent and fading amount of indoor channel. The total $\mathbf{1 0 0}$ coordinates of user's positions are estimated using min-max method. The distance error at each position, probability density function (PDF) and cumulative distribution function (CDF) of distance errors are illustrated. The mean of analysis distance error corresponds with the mean of measurement distance error with same path loss exponent and fading amount of indoor channel. The results show that it is possible to use this accuracy analysis to estimate the distance error in an indoor environment.

    Impulse radio is another wireless communication technology developed for short-range communications, with low transmission power and wideband frequency. Which compliance with communication systems that require the speed of transmitting large amounts of data. Therefore, this project has designed and fabrication a biconical antenna. Furthermore, perform the antenna's performance test for an indoor impulse radio localization in the frequency range of 3.1 GHz to 10.6 GHz with a vector network analyzer. The results of the measurements were analyzed and evaluated in comparison with the distance error with matched filter and time-gating techniques. The results obtained from the study of this project are based on theory and very useful for basic information in the research and development of short-range wireless communication systems and positioning by impulse radio transmission.
