Oscilloquartz unveils dual-antenna GNSS SyncReach for small cells

May 25, 2017  - By

Oscilloquartz has launched the OSA 5405 SyncReach, an integrated PTP grandmaster and GNSS receiver with a patent-pending dual antenna and receiver to enable the mass roll out of small cells.

The new 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.

With the OSA 5405, operators can migrate from legacy GNSS RF antennas and cables to standard, cost-effective copper and fiber Ethernet cabling, reducing capital expenditure and operating expenses, Oscilloquartz said.

Available in both indoor and outdoor variants, the OSA 5405 can be deployed in challenging environments, including urban canyons where GPS signals fail. The OSA 5405’s 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 uses a unique dual GNSS antenna and receiver algorithm to mitigate interference from multipath signals that can affect accuracy, particularly in urban canyons, according to the company.

“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,” said Gil Biran, general manager at Oscilloquartz. “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.

“We’ve created our OSA 5405 to effectively deliver small cell synchronization in any environment and eliminate all restrictions,” Biran said. “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 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 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 feature of the new technology is IP connectivity, so 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.

“Make no mistake; the launch of our OSA 5405 is a major milestone in the progress towards mass-scale small cell deployment,” said Nir Laufer, product line director at Oscilloquartz. “With its plug-and-play simplicity, miniscule form factor and multiple timing functions in a single device, this is a key technology for 5G networks and the IoT.

“Currently deployed in trials with major carriers, it will shortly be available to all operators looking to harness next-generation synchronization precisely where it’s needed,” Laufer said.
