In this paper an algorithm has been proposed based on Hata model that employs an improved procedure in detecting the mobile location in three dimensional environment using received signal strength (RSS). This technique considers path loss and shadowing effect for the channel to compute the distance between the mobile phone and its home base station and neighboring base stations using Hata model. Considering the distance from the mobile phone to the base station (including its home base station) as the radius of the sphere (i.e., shape produced by signal propagation from Omni directional antenna) to find out an intersection point of all these spheres that denotes the location of the mobile phone. An intersection point of all these spheres is computed that denotes the location of the mobile phone. The algorithm has been simulated and the result has been found to be accurate.

Though many location algorithms, such as least square methods, fingerprints, data fusion and proximity methods, have been suggested for positions estimation, most of their performances have been valuated based on the proposed simulations. The solution of distinguishing NLOS environments is still a Gordian knot. Our studies focus on the utilization of measurement report which is generated by the user equipment and contains the information of cell configurations and signal strengths. As the cell antenna azimuths which belong to the same base stations direct respectively, this paper suggests a notion of virtual antenna for wireless location in practical environment. The cells are categorized and a virtual antenna is defined to indicate mobile's direction more accurately. A step-by-step algorithm is also suggested for fitting the azimuths. The experiment of field measurements exhibits the high accuracies of our virtual antenna and a comparability of the fingerprints algorithm and our studies is shown.
