Abstract
Wi-Fi fingerprinting is a promising technique for indoor localization. The use of both 2.4 GHz and 5 GHz for Wi-Fi fingerprinting has been preliminarily studied by some research groups. However, most of the previous studies only consider the reflection and multi-paths caused by walls around but do not consider the damping and scattering through walls between them. In this paper, we particularly consider the situation that the radio propagation covers several rooms divided by walls, and compare the localization performance of using 2.4 GHz and 5 GHz networks. Moreover, we also compare the power consumption of scanning the surrounding wireless channels used for 2.4 GHz and 5 GHz networks. The results show that the performance of accuracy of Wi-Fi fingerprinting is similar when using 2.4 GHz and 5 GHz respectively. However, the use of 5 GHz results in higher response rate, while the use of 2.4 GHz consumes less power.
