WiMAX (Worldwide Interoperability for Microwave Access)

As WIMAX projects develop it becomes clear that licensed spectrum implementations are calling for Time Division Duplexing WIMAX (TDD WIMAX) to optimize their efficiency and usage of a limited spectrum. TDD WIMAX, WIBRO and the soon available 802.16e (mobile WIMAX) put stringent phase timing constraints to the synchronization of base stations.

The solution is to phase synchronize all base stations with highly accurate and perfectly phase aligned GPS receivers clocks. Oscilloquartz has developed several specific WiMAX GPS receivers, based on a highly stable Double Oven Crystal Oscillator (DOCXO). The product line represented under OSA WIMAX series exceeds TDD WIMAX requirements especially in the domain of phase alignment. Beyond the several limited field trials, the OSA WIMAX series was chosen for the synchronization of the largest WIMAX Metropolitan Area Network in TOKYO where more than 1200 base stations are being deployed.

Higher grade Base Station synchronization is required where operators do not compromise between Quality of Service, Speed of transmission and optimal usage of the limited bandwidth. OSA WIMAX series is a versatile solution that can be integrated in different available form factors to accommodate the different types of Base Stations.


OSA 5420 Series

Our OSA 5420 series is a family of cost-effective, mid-scale synchronization distribution and assurance devices that bring the power of Syncjack™ to any network. Following a toolbox approach, the family members of the OSA 5420 series can be utilized in a variety of network synchronization applications, including IEEE 1588v2 Grandmaster, Boundary Clock, Slave Clock and Assisted Partial Timing Support (APTS).
