electronica 2012 Company Profile 4G eNodeB entered the era of TIME ACCURACY with Oscilloquartz Coupled with any of the above 3, eNodeB can typically achieve: Time Synchronization: Value for Money Legacy 2G & 3G technologies are mostly based on Frequency - sub-microsecond holdover for hours, Accuracy (FA) as their radio signals are based on Frequency - less than 5 microseconds for 24 hours indoor , Duplexing (FDD). Quality of service can be delivered based on -less than 9 microseconds for24 hours outdoor with wide a 5 x E-8 FA which is typically provided by entry level OCXOs temperature daily excursions. locked on GPS receivers to avoid long term frequency drift. A transition to Time Accuracy (TA) came with the introduction of TDD (Time Division Duplexing) type of radio in Asia, namely TD- SCDMA and TD-LTE. This technology is based on Time Slots that require TA to function. The transition to TA is also driven by the deployment of Timing Critical services, namely Location Based Services (LBS) as well as Multimedia Broadcasting MBMS/MBSFN which both require TA even when deployed over FDD LTE. Their implementation will necessitate the upgrade of the majority of eNodeB with microsecond level TA in all conditions, including the possible loss of Time Reference (GPS or IEEE1588) for long hours of so called Holdover. The challenge comes with the obligation to maintain 24 hours of Holdover and especially so with a tight Time Error in outdoor base stations which are subject to wide Value for money. While OSA provides the Highest Holdover per- temperature excursions. formance to TD-LTE eNodeB with no compromise, its 3 levels Since 2004, Oscilloquartz S.A. (OSA) has been developing its products have also been designed based on ambitious cost SYNC technology to support the transition to TA.
