Nokia and ADVA demo end-to-end 5G synchronization

ADVA and Nokia jointly demonstrated end-to-end network timing with the accuracy and resilience needed for 5G services.

The demonstration, which was presented at Orange Poland’s Innovation Garden Summit, highlighted how precise phase and frequency synchronization can be delivered and assured from the core to the cell site without risk from GNSS vulnerabilities.

The live showcase in Warsaw featured ADVA’s diverse range of Oscilloquartz products. This includes ultra-compact small-form-factor solutions designed to be utilized in large numbers even in the most challenging and space-restrictive conditions.

ADVA said its solutions meet the urgent demand for precise timing at the network edge. At the other end of the scale are Oscilloquartz modular, high-performance IEEE 1588v2 PTP core grandmasters that provide ultimate scale with a carrier-class design and in-built hardware redundancy. As part of the OSA ePRTC system, these provide an ultra-precise source of time with guaranteed holdover performance, removing the risk of reliance on GNSS alone.

“Our joint demo with Nokia answers the most urgent timing challenges facing today’s network operators. It highlights how our solutions can accelerate the deployment of 5G, IoT and mobile edge computing by delivering new levels of accuracy and stability for phase and frequency synchronization,” said Jörg Urban, senior director, business development, Oscilloquartz, ADVA. “We’re showing Tier 1 CSPs how easy it is to distribute, monitor and assure end-to-end timing that is fully resistant to GNSS outages. The precision and reliability that our technology offers will empower operators to support emerging applications in fields such as highly interactive augmented reality and self-driving vehicles.”

BT employs ADVA's precision synchronization for 5G


BT is deploying ADVA's Oscilloquartz synchronization technology to bring 4G coverage to previously underserved areas and begin the rollout of 5G services across the UK. The new synchronization solution is deployed nationwide in 10 core time base sites, 106 metro time sites and close to 1,000 Tier 1 sites at the network edge. Prior to this deployment, BT’s timing network was based purely on frequency synchronization. ADVA said its Oscilloquartz...

NTT improves GPS Time Synchronization

NTT and FURUNO ELECTRIC CO. have developed a receiver for GPS and other global navigation satellite systems (GNSS) that significantly improves time-synchronization accuracy in areas with severe reception conditions such as among buildings and in mountainous areas.

NTT said its new satellite signal selection algorithm and a time synchronization GNSS receiver from FURUNO makes it possible to use multi-path satellite signals (reflected or diffracted from buildings and other structures), which previously inhibited accuracy of time synchronization. In a real multi-path reception test environment, time error was reduced to approximately 1/5 of earlier values. This is a remarkable result in that it promises to enable time synchronization accuracy close to that obtained in open-sky reception environments with no obstructions, even in environments previously considered poor and unsuitable for accurate time synchronization, such as among buildings or in mountainous areas.

FURUNO plans to begin sales of their new GF-88 series time synchronization GNSS receivers incorporating this new technology in April of 2019. Potential applications include  4G/5G mobile base stations, financial trading, power grids, and data centers.

ADVA's Oscilloquartz intros modular sync solution with 10G interfaces

ADVA Optical Networking's Oscilloquartz division introduced the first IEEE 1588 grandmaster clock device on the market to support PTP, NTP and SyncE over multiple 10Gbit/s Ethernet interfaces.

The new OSA 5430, which is designed to help network operators achieve the stringent phase and time synchronization requirements needed for LTE-TDD, LTE-A and 5G RAN networks, can be deployed in the core and at centralized aggregation locations.

It features fully redundant hardware -- in case one critical module fails, another instantly takes over. Built-in Syncjack assurance functionality ensures that operations teams are alerted to any issues before services are affected.

"Our OSA 5430 is a major milestone for network timing. With today's launch, we're answering the key challenges facing today's operators as they roll out next-generation technologies such as LTE-A, and addressing the urgent synchronization needs of finance and cable companies. This device provides a smooth transition from legacy sync and supports levels of integration never before seen in the industry. Interest in our OSA 5430 is extremely strong with major Tier 1 customers already secured," said Gil Biran, general manager, Oscilloquartz. "

Microsemi upgrades TimeProvider 5000 PTP grandmaster clock

Microsemi, a major provider of high performance, low power semiconductor solutions, has updated the hardware on its TimeProvider 5000 IEEE 1588 Precision Time Protocol (PTP) grandmaster clock to provide support for IPv6 and multi-Global Navigation Satellite System (GNSS) constellation, offering improved reception and higher security for a range of telecom network applications.

The company noted that global operators are increasingly seeking solutions such as its enhanced TimeProvider 5000 product to meet the requirement of directives in certain countries to support multiple constellations to remove the dependency on GPS. In addition, via support for both GLONASS and Galileo constellations systems can be made more robust and secure against certain GNSS vulnerabilities.

Microsemi stated that the TimeProvider product family has been installed in over 350 networks globally to support high performance, reliable network infrastructures. Combined with newly added support for IPv6 and multi-GNSS constellations, the TimeProvider 5000 also provides redundant hardware, user configurable PTP profiles and Synchronous Ethernet (SyncE) support with optical small form-factor pluggable (SFP) modules.

Orange Egypt selects Oscilloquartz Synchronisation for LTE Roll-out

Oscilloquartz, a supplier of timing solutions and an ADVA Optical Networking company, announced that Orange Egypt, a company of France-based global telco Orange, has deployed its OSA 5421 technology as part of a complete synchronisation solution.

The advanced precision time protocol (PTP) grandmaster clocks from Oscilloquartz are designed to distribute and assure accurate timing throughout the national network in Egypt. The end-to-end synchronisation solution will also support the phase and frequency requirements required for Orange Egypt's large-scale deployment of LTE and LTE-Advanced (LTE-A) capabilities.

It was noted that in October 2016, Orange Egypt became the first mobile operator in Egypt to be awarded a license to operate 4G services, which the company is now rolling out supported by an investment of around $484 million. The new network and services are supported by the synchronisation network based on the Oscilloquartz OSA 5421 solution.

Oscilloquartz's advanced PTP grandmaster clock is a compact synchronisation distribution and assurance device that incorporates the vendor's Syncjack technology that enables continual monitoring. The solution is designed to deliver both the accurate phase and frequency information required for Orange Egypt's 4G services and provide assisted partial timing support via a quartz oscillator that allows extended holdover in the case of GNSS outages. In addition, the solution is optimised for deployment at the network edge.

In November 2016, Oscilloquartz announced it had been selected to synchronise a national core transport network being deployed for India's armed forces. The 60,000 km infrastructure, being built by a consortium led by Himachal Futuristic Communications (HFCL), featured Oscilloquartz technology to provide precise frequency and phase delivery leveraging its caesium beam clock and synchronisation supply unit, plus its synchronisation management system, SyncView Plus.
