Performance of the system is analyzed for different mobile holding positions viz. horizontal to floor and casual mobile holding angle. Using 12-bit unique ID transmission, the proposed system can address 4096 lights. A total of 163 unique IDs from ID number 25 to ID number 4096 (in steps of 25) has been taken for analysis. For each ID, 3 to 4 attempts have been experimented. Out of 1138 test cases, 913 cases are positive and 225 are negative. Accuracy obtained for horizontal to floor position and casual mobile holding angle positions are 79.5% and 80.95% respectively. Results show that NLOS approach is user friendly and can achieve up to 80% accuracy. |
