Symmetricom introduced a set of Edge Master Clocks for delivering precise time at the network edge, especially in 3G and 4G/LTE small cell deployments.
The TimeProvider 2700 and 2300 Edge Master Clocks are IEEE 1588 (PTP) synchronization solutions.
In addition to locating a grandmaster clock at or near the edge, the platforms can be used to overlay the network with advanced boundary clocks at specific locations. Support covers both LTE-TDD and LTE-A, which have stringent requirements for frequency and phase synchronization.
In frequency synchronized networks (LTE-FDD, as well as 2G/3G), Edge Master Clocks can be deployed to eliminate timing issues caused by the backhaul network and high packet delay (PDV) environments inherent in Carrier Ethernet networks.
Multi-sync capability ensures service continuity in the event of loss of one or more of the primary sync signals or the GNSS signal is compromised.
The solution is also optimized for deployment in small to large networks with license options supporting between 8 and 64 base stations and/or small cells, allowing for network scalability.
“Small cells synchronization is a multi-faceted challenge and requires an innovative approach,” said Manish Gupta, vice president of marketing and business development for Symmetricom. The TimeProvider 2700 and 2300 Edge Master Clocks are specifically designed to meet the
scalability, performance, reliability and cost requirements for synchronizing small cells at the
edge of the mobile network.”
“Small cells are necessary to increase capacity and coverage required by data hungry customers who continue to consume data as a part of their mobile lifestyles,” said Dror Nemirovsky, Head of Packet Networks, Nokia Siemens Networks. “The Symmetricom Edge Master Clocks complement the investment our customers have made in the TimeProvider 5000 and enable Nokia Siemens Networks to serve operator requirements for increased network performance as they deploy LTE.”
