The unit is an integrated PTP (precision time protocol) grandmaster and GNSS receiver with a dual antenna and receiver to enable the mass roll out of small cells. The technology has been 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. With the OSA 5405 operators can migrate from legacy GNSS RF antennas and cables to standard, cost-effective copper and fibre Ethernet cabling. Available in both indoor and outdoor variants, the OSA 5405 can be deployed in the most challenging environments, including urban canyons where GPS signals fail. The OSA 5405’s small form factor also enables it to be positioned on indoor windows to avoid multipath signal interference from objects within the building.
“We’re at the start of a new era. With the internet of things (IoT) connecting more wireless devices and 5G just around the corner, small cells will have a big role to play. This market is set to grow exponentially in the next few years. Small cells will soon be everywhere and that makes precise synchronization essential. Operators urgently need a way to reliably and affordably deliver new levels of phase accuracy,” said Gil Biran, general manager, Oscilloquartz. “We’ve created our OSA 5405 to effectively deliver small cell synchronization in any environment and eliminate all restrictions. Our new technology radically simplifies 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 fibre 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 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 fibre. The ADVA FSP Network Manager with comprehensive Syncjack assurance guarantees efficient operation. The OSA 5405 uses a unique dual GNSS antenna and receiver algorithm to mitigate interference from multipath signals that can affect accuracy, particularly in urban canyons.
