Wireless synchronization based on beacons

A system comprising:

• a link layer to receive a beacon timestamp from a wireless network;
• a processor to receive the beacon timestamp from the link layer;
• an output port controlled by the processor to cause an interrupt at the link layer to initiate a capture of a link layer timestamp at the link layer relative to the beacon timestamp;
• an input port on the processor to receive the link layer time stamp from the link layer in response to the interrupt at the link layer;
• and
• a synchronizer to capture a processor timestamp relative to the beacon timestamp and determine a time offset value relative to the received link layer time stamp from the link layer by computing a difference between the processor timestamp and the link layer timestamp, wherein the time offset value is combined with the processor timestamp to synchronize the processor with respect to the beacon timestamp received at the link layer.

A method comprising:

• receive a beacon timestamp from a wireless network;
• generating an interrupt to initiate a capture of a link layer timestamp relative to the beacon timestamp;
• capturing a processor timestamp relative to the beacon timestamp;
• and
• determining a time offset value relative to the link layer time stamp by computing a difference between the processor timestamp and the link layer timestamp, wherein the time offset value is combined with the processor timestamp to synchronize at least two wireless devices operating on the wireless network.
