WebPTP is originally designed for LANs (IEEE 1588) [1] and can achieve nanosecond accuracy through timestamping the network packets. Attempts to extend PTP to wireless LAN or Wi-Fi can be traced back to the early Wi-Fi era [29]. The major difference from the wired situation is that the wire-less channel introduces uncertainties in PTP timestamps [22].
