accessSync™ miniature PTP grandmasters

Precision synchronization in the smallest form factor

As networks grow more complex, synchronization demands greater agility, efficiency, and compact design. Whether facilitating seamless 5G and 6G deployments or supporting critical applications in utilities, finance, and broadcasting, operators need precision timing solutions that perform deep within the network. Our accessSync™ miniature PTP grandmasters meet these needs with innovative, space-saving designs that deliver unrivaled accuracy and reliability at the network edge.


Compact synchronization solutions for resilient networks

Our accessSync™ portfolio brings precision timing where it’s needed most, combining compact form factors with advanced features like GNSS receivers, PTP grandmaster capabilities and robust Syncjack™ monitoring. Designed for challenging environments, these devices offer resilient synchronization even in areas with GNSS vulnerabilities like jamming or poor signal reception. Their low-power, plug-and-play design simplifies deployment, making them ideal for dense urban areas, power utilities and remote locations.



Reliable timing for GNSS-challenged environments

Our accessSync™ miniature PTP grandmaster portfolio delivers high-performance synchronization in ultra-compact packages. These solutions integrate seamlessly with existing systems and offer advanced GNSS receivers, smart antenna technology and support for alternative time sources like Satellite Time and Location (STL). Designed for both indoor and outdoor deployments, power utilities and GNSS-challenged environments, the portfolio sets new benchmarks for cost-efficient, precise synchronization in mission-critical applications.
