Field Test Plan frequency sync using SDH PDH

Frequency synchronization is critical for all mobile technologies. SDH synchronization to NodeB or eNodeB devices must meet tight ITU-T metrics. This test plan provides field test procedures to ensure high quality synchronization for mobile backhaul networks which are synchronized by SDH/PDH.

Synchronization for Small Cells

All cellular radio base stations require synchronization, including small cells. This may be frequency synchronization, phase alignment to other base stations, or time synchronization. This paper is a small cell tutorial in conjunction with MEF.

Field Test Plan for PTP frequency sync

One in a series of three Field Test Plans using Calnex Sentinel. Frequency synchronization is critical for all mobile technologies. PTP synchronization to NodeB/eNodeB devices must meet tight ITU-T standard specifications as well as vendor specific limits.

Why Mobile Synchronization?

This critical requirement in today's networks is explored by considering six key questions. Topics covered include basestations, small cells, home cells, time and frequency synchronization, LTE and advanced LTE networks.

An overview of Time and Time Error

From the beginning, a full disussion on the concepts of time. What is Time and why is it important? The paper then focuses in on time distribution, the concept of Time Error, the sources of Time Error and Time Error Budget. Measuring Time Error.

Network Latency & TCP

The impact of latency on loss of throughput and other problems caused by latency. The challenges of migrating to today's high speed networks running at 40G and 100G are discussed along with the role of TCP as an enabling technology.
