Effective support of advanced applications and services in mobile networks today requires highly accurate distribution of time reference to all base stations, using a Global Navigation Satellite System, or GNSS (e.g., GPS). This paper addresses the increasingly threatening risk of GNSS jamming and reviews best practices for anti-jam protection.

This paper reviews the various methodologies currently available for ensuring Time Of Day (TOD) synchronization in cellular networks. It also introduces RAD’s revolutionary Distributed GMTM scheme, designed to deliver superb TOD accuracy at a lower cost in LTE and small cell networks, by bringing Grandmaster functionality closer to the base station in a small form factor device.

What you will learn:

Ensure profitable Ethernet service delivery by streamlining the deployment, monitoring and maintenance of such services.

This practical guide describes the various test procedures, along with implementation considerations and recommendations for use at turn-up, ongoing monitoring and other critical points throughout the service lifecycle to ensure quality of service and maintain Ethernet COS.

A RAD-sponsored guide to Ethernet OAM standards, including IEEE 802.3-2005 (previously 802.3ah, Clause 57), IEEE 802.1ag and ITU-T Y.1731OAM is a set of functions designed to monitor network operation in order to detect network faults and measure its performance. As Ethernet evolves from enterprise-level LANs to carrier-class networks and services, it requires automated end-to-end management and monitoring by service providers.
