Perfect Timing!

May 21, 2014 by Ixia Blog Team

The Ixia theater opened today with Seibastien Jabert, Iometrix director of Engineering, describing how poor mobile backhaul synchronization for 4G/LTE and 5G/LTE-A base stations results in interference, unsuccessful handovers, inefficient radio spectrum use, and ultimately, poor user experience.

Service providers using packet-based mobile backhaul networks and the vendors that supply them with gear have adopted the IEEE 1588 Precision Timing Protocol (PTP) to ensure a sharp focus on accuracy of Packet Master Clocks and Packet Slave Clocks. This is where Iometrix comes in. The company provides the industry’s first IEEE 1588 certification program in telecom environments (IEEE Std1588-2008 and ITU-T G.8265.1 standards), completing the standardization process with a single and universally-recognized conformity assessment testing process based on an industry-approved test plan.

Iometrix uses Ixia’s IxNetwork for network emulation and analysis, as well as master and slave clock functions in the company’s IEEE 1588 test bed for Packet Master Clock and for Packet Slave Clock. Currently there are well over 300 test cases defined for each clock function in the test plan.
