Abstract:
A control station for a fourth-generation (4G) automatic link establishment (ALE) network is disclosed. In embodiments, the control station is GPS-enabled or has a comparable precise timing source for generating timing information including the minute, second, and millisecond a protocol data unit (PDU) is to begin. The control station has a transceiver assembly for encoding the millisecond data and embedding the encoded millisecond data (as well as the minute and second data) within a Time-of-Day (TOD) Response or comparable time broadcast PDU. The PDU is transmitted to unsynchronized nodes of the 4G ALE network allowing for more precise time synchronization to the control station.
