Abstract
The goal of this research is to evaluate the location accuracy of User Equipment (UE) in Long Term Evolution (LTE) networks which depends on the timing advance parameters. The ability to locate the subscribers through the network is considered as a significant factor in wireless communication systems. The main method to geolocation based on specified distances from many base stations is stated. The possibility of geolocating a Long Term Evolution (LTE) subscriber station based on the timing advance ranging parameter within the network signal internals is investigated in the paper. Also, simulation is used to describe performance in multiple base station networks that evaluating locations of subscriber stations on a two-dimensional system coordinated. Performance estimation of UE location in LTE networks was analyzed using simulations. Simulations were performed by using MATLAB. The main method for determining the subscriber station location depends on radial distances from multiple base stations. We observe from the results that the calculation error for the network is frivolous and by using four eNodeBs we obtain the most accurate estimation. Our simulation analysis shows that increasing the eNodeBs that used in the network leads to increasing the error to 29 centimeters.

Since previous few years, the growing demands for accessing the Internet through the mobile devices were noticed
Modeling geolocation techniques used in the two-dimensional aspect, we focus on simulating a multiple base post meshwork with varying scenario of base station placements and Timing Advance (TA)-based radii fluctuations and approximate a subscriber station’s location
Summary
The growing demands for accessing the Internet through the mobile devices were noticed. As a result of this effort, the Long Term Evolution (LTE) technology has been introduced. LTE system provides comprehensive support for Frequency Division Duplexing (FDD), Time Division Duplexing (TDD) and spectrum flexibility. It targets a soft evolution from previously Third Generation Partnership Project (3GPP) technologies such as Time Division Synchronous Code Division Multiple Access (TDSCDMA). LTE is incessantly evolving to meet current and future requirements as well.
