Indoor localization has turned into a field of research densely populated with studies covering a large range of technologies, system designs and localization algorithms. Simply adopting outdoor solutions is not feasible but it is possible to adapt existing algorithms for outdoor positioning to cope with the specifics of indoor environments. The authors' work aims to adapt the Time Difference Of Arrival (TDOA) technique to work with GSM signals and, subsequently, to improve its performance indoors. In a nutshell, the final localisation system should deliver high accuracy, e.g., down to a meter, not need participation of the user and be easily portable.
