description Beberapa teknologi lokasi telah dibangunkan dan secara komersialnya telah digunakan secara berkesan termasuklah Sistem Kedudukan Sejagat (Global Positioning System, GPS) dan sistem khidmat 911 tertingkat wayarles (E-911). Namun demikian, teknologi ini digunakan khusus untuk aplikasi luar dan tidak begitu berkesan jika digunakan di dalam bangunan atau di kawasan Bandar yang padat. Kebanyakan sistem lokasi dalaman komersial yang ada agak lemah prestasinya kerana wujudnya hinggar, gangguan, hilang laluan, pengutuban yang tidak sepadan, pantulan pengutuban dan kesan fenomena pelbagai laluan dalam saluran wayarles. Oleh itu, suatu sistem lokasi yang mempunyai prestasi yang baik untuk persekitaran yang tertutup amat diperlukan. Several locating technologies have been developed and commercially deployed including the Global Positioning System (GPS) and the wireless enhanced 911 service system (E-911), but these locating technologies are used mainly for outdoor locationbased applications and can not be used effectively inside buildings and in dense urban areas. Most of the commercial indoor localization systems provide a poor performance due to the presence of noise, interference, path loss, polarization mismatch, polarization reflection and the effect of the multi-path phenomenon in the wireless channel. Therefore, there is a need for a locating system which has a good performance in indoor environments .
