| Abstract(in English) | In environmental measurement fields such as seismic observations, measuring environmental data with high precision clock is required. In the measurement field, a communication network is often con figured by wireless connections. In order to accurately synchronize clocks of the mobile terminals on the network, the previous study has developed Precision Time Protocol (PTP) of IEEE 1588 for IEEE802.11 wireless network, which has achieved lOus as accuracy. This precise clock synchronization is, however, supported only by Wi-Fi card and the clock is not provided to its host computers. If this precise clock can be used by any application on host PC, flexibility will significantly increase. Therefore, we study how applications of host PC obtain the precise clock information stored in the Wi-Fi card. In this paper, we implemented the PTP system and report the experiment result and the evaluation. |
