Abstract:
A high definition timing synchronization function is described. In an embodiment, a wireless station generates a time stamp at a higher resolution than can be broadcast within a standard time stamp field in a frame. The generated time stamp is divided into two parts: the first part being included within the time stamp field and the second part being included within a vendor specific field in the same frame. The frame is transmitted by the wireless station and received by other wireless stations in the wireless network. If the receiving wireless station has the capability, it decodes both the time stamp field and the vendor specific field and recreates the higher resolution time stamp. This higher resolution time stamp is then used to synchronize the receiving wireless station and the transmitting wireless station by resetting a clock or by storing time stamps and corresponding clock values.
