Mobile based localisation for assisting disabled people.

M. Tech.: Electrical Engineering. / The purpose of this research was to design a low cost mobile positioning system based on Global System for Mobile communication network. The positioning system utilises Timing Advance, Signal Strength, a calibrated propagation system based on per -cell modelling and field measurements data to calculate the mobile position. Clutter and terrain features such as trees and buildings were modelled to closely represent the real environment to enhance the accuracy of the Signal Strength prediction. The key pillar of this approach is its ability to establish the contribution of each of the localised features to the propagation model. Based on the magnitude of the contribution of each feature, a conclusive correction factor for each feature was obtained. The proposed system is evaluated using field measurements collected from a Global System for Mobile communication network in diverse geographic locations in the outskirts of Pretoria. A fair correlation was established between field measurements and propagation model predictions.
