Abstract
A system for adding a time stamp to transmission traffic on a wireless network comprises a front end processor that receives a packet from the network and generates a Start Of Frame pulse and a LENGTH field corresponding to a length of the packet. A time stamp generator generates a time stamp by sampling the system master time counter. A synchronizer receives the SOF pulse and the LENGTH field from the front end processor, and generates a control signal. A multiplexer inputs the packet from the front end processor, the control signal and the time stamp, and outputs a modified packet with a field in the packet replaced by the time stamp.
