To meet exploding bandwidth demand, mobile operators are upgrading backhaul networks to packet-based technology. This transition brings a major challenge: maintaining synchronization, a mandatory requirement for mobile network stability and handset handoff. As Ethernet is an asynchronous technology, newer methods and standards have been introduced to implement synchronization over Ethernet. Namely, IEEE 1588v2 PTP is becoming the choice solution for synchronization distribution, as it uses an exchange of timestamp between master and slave devices, thus providing frequency, phase and time sync over the existing Ethernet infrastructure.
