Abstract

An apparatus and method of scheduling timing packets to enhance time distribution includes an improved apparatus in a system in which at least one of time and frequency information is derived based on information distributed in timing packets, at least some of the timing packets being transmitted by or received by the apparatus. The improvement includes a scheduling module that determines a first packet transmission time offset of a first timing packet based on a first predetermined identifier associated with the apparatus, and a second packet transmission time offset of a second timing packet based on the first packet transmission time offset and a timing packet spacing that is independent of the first predetermined identifier. The improvement further includes a transmission module that transmits the first timing packet based on the first packet transmission time offset, and the second timing packet based on the second packet transmission time offset.
