IEEE/ICACT20210244 Slide.06        [Big Slide]       Oral Presentation
At first, we conducted an experiment of timestamp measurement using IEEE 802.11g frame transmitter in an anechoic chamber. We measured two kinds of timestamp. One is epoch time. This is OS-level timestamp. The other is TSF timestamp. This is device-level timestamp in IEEE 802.11 wireless LAN. We use four measurement laptop PCs as shown in here. MAC and Linux PCs can obtain TSF timestamp, but Windows PCs cannot obtain TSF timestamp.
