Indoor/Outdoor PTP Grandmaster & GNSS Receiver to Enable the Small Cells Era

Oscilloquartz, an ADVA Optical Networking company has launched an integrated PTP (Precision Time Protocol) grandmaster and GNSS receiver with a patent-pending dual antenna and receiver to enable the small cells era. The new OSA 5405 SyncReach technology has been specifically engineered to provide accurate and affordable phase synchronization for the rapidly growing small cell market and meet the stringent timing requirements of 4.5G and 5G connectivity.

Oscilloquartz is a pioneer in time and frequency synchronization. They have been designing, manufacturing and deploying end-to- end synchronization systems that ensure the delivery and assurance of highly precise timing information over next-generation packet and legacy networks.

With the OSA 5405, operators can now migrate from legacy GNSS RF antennas and cables to standard, cost-effective copper and fiber Ethernet cabling, reducing capital expenditure and operating expenses. Available in both indoor and outdoor variants, they can be deployed in the most challenging environments, including urban canyons where GPS signals fail. Its miniscule form factor also enables it to be positioned on indoor windows to avoid multipath signal interference from objects within the building.

The OSA 5405 has been created to effectively deliver small cell synchronization in any environment and eliminate all restrictions by radically simplifying GNSS antenna installation. The use of PTP removes the need to compensate for cable delay and extends the reach of GNSS. It enables operators to forget about archaic and expensive RF cables and use simple copper cabling or optical fiber for longer distances. And with variants that can be positioned in almost any location, it provides strictly accurate timing precisely where it's needed.

The compact design and power-over-Ethernet capabilities of the indoor- or outdoor-mounted OSA 5405, enable synchronization right at the edge of the mobile network. This creates dramatic reductions in complexity and power requirements as well as lower costs for installation and operation. Another key feature of the new technology is IP connectivity. This means that synchronization becomes another element of the internet of things.

The OSA 5405's highly precise GNSS-sourced synchronization is supported by network-based Sync-E and PTP backups. In high-rise buildings it can also deliver synchronization recovered from the GNSS smart receiver over optical fiber. The ADVA FSP Network Manager with comprehensive Syncjack assurance guarantees efficient operation. It also uses a unique dual GNSS antenna and receiver algorithm to mitigate interference from multipath signals that can affect accuracy, particularly in urban canyons.
