Abstract
Apparatuses, methods, and systems for a network-based clock for time distribution across a wireless network, are disclosed. One system includes a network that includes a time distributor, a time receiver, and a plurality of network elements providing one or more network connections between the time distributor and the time receiver. The plurality of network elements includes an ingress network element and an egress network element. The time distributor receives and synchronizes to a first clock. Two or more of the plurality of network elements receives and synchronize to a second clock. A forward network transit delay is determined between the ingress network element and the egress network element and a backward network transit delay is determined between the egress network element and the ingress network element. The time receiver time synchronizes to the time distributor using the forward network transit delay and the backward network transit delay.
