E-SIC is an algorithm designed to synchronize the clocks of embedded controllers through a Local Area Network (LAN) using 802.11 (WI-FI) technology. It’s based on the SIC algorithm that synchronizes frequency between the clocks by taking advantage of the symmetry of the networks round trip time. By considering an historic window of measurements and the usage of the mode as an estimation tool, the E-SIC algorithm has achieved absolute clock sync between two devices with a higher accuracy than two milliseconds without the requirement of extra hardware.
