Symmetricom - As mobile operators need to transport more data for less money, TDM transport becomes less viable.  IP/Carrier Ethernet overcomes the economic and capacity limitations of TDM.  However, IP requires QoS and synchronization to be consciously engineered into the solution.  This paper addresses the business challenges of moving to IP/Carrier Ethernet and explores the alternatives for deploying sync delivery mechanisms such as SyncE, IEEE 1588 (PTP) and GPS.  This practical guide to selecting a synchronization strategy for Long Term Evolution (LTE) systems provides a clear, in-depth look at defining IP related sync objectives, assessing multiple sync technologies and understanding topics such as on-path support.
