ADVA deploys Timing Synchronization to Its FSP 150 Family

To support the large-scale rollout of small cells for LTE-Advanced and radio access networks  operating in unpaired spectrum, ADVA Optical Networking has announced that it has included an IEEE 1588v2 mini-Grandmaster (miniGM) clock and Boundary Clock functionality to its FSP 150 family of mobile backhaul products. This addition will ensure precise frequency and time synchronization at the network edge. The miniGM is designed to simplify the migration to LTE and LTE-Advanced radio access networks.

Christoph Glingener, CTO, ADVA Optical Networking, said, As mobile operators gradually introduce LTE-Advanced, they are finding network synchronization increasingly complex. This is all due to the necessary rollout of interference coordination and radio spectrum control techniques. Base station clocks now need to operate in phase within tolerances of less than a micro-second. This is a considerable challenge. But by deploying the miniGM functionality at the edge of the backhaul network and introducing our Syncjack timing assurance technology, mobile operators and their mobile backhaul service providers can meet these synchronization demands while improving their customer's quality of experience.
 
Deploying the miniGM enables the utilization of existing networks for backhaul services connecting LTE-Advanced radio access networks.
