摘要： Systems, apparatus, methods and computer program products are provided for causing a dataframe to be emitted at an air interface of an antenna. A memory stores a transmission to antenna delay value (TAD). An offset calculator calculates an offset value based on an epoch of a global timebase generator and the transmission to antenna delay value (TAD). An interface controller in communication with the offset calculator communicates a segment synchronization signal and a field synchronization signal based on the offset value.
