Avateq Showcasing at 2022 NAB Show

  • 20 April, 2022

 

CAN: Avateq Corp. invites you to booth #W7824 to learn about the latest enhancements of Avateq's signal analyzers and monitoring receivers with new functionality and tools:

  • A new generation of our flagship AVQ1022 - RF Signal Analyzer introduces advanced support for STLTP monitoring and analysis. Detailed reporting of STLTP data at the input of the exciter and decoded data at the transmitter output provides invaluable insight into the performance of the ATSC 3.0 delivery chain.
     
  • AVQ200 - RF Signal Inspector for ATSC 3.0 is a great tool for in-field signal analysis. With an option for GPS data recording, the unit can store a detailed view of the signal distribution in the service area for further mapping and analysis. AVQ200 features SFN monitoring tools that include proprietary frequency shift calculation for each detected SFN signal.
     
  • AVQ1020 2ndGen - RF Layer Monitoring Receiver continues to be the choice for transmitter site ATSC 3.0 signal monitoring. Avateq would like to remind that a program for hardware upgrades is available. The upgrade is a cost-effective way to support the transition for ATSC 3.0 broadcasting.
     

Innovative Spectrum Utilization
Analysis for ATSC 3.0

Avateq helps content providers and data distributors to bring ATSC 3.0 datacasting to a new level by increasing the quality of service and optimizing RF channel utilization.

The rollout of ATSC 3.0 across the Unties States highlights datacasting as the new mean for content and data delivery. Effective spectrum utilization by modern communication and broadcast technologies becomes vital as new services emerge and consume extremely limited spectral resources. To assist the industry Avateq Corp. introduces an innovative Spectrum Utilization Analysis for practical in-field estimation and adaptive controlling of the ATSC3.0 RF channel fill factor. The tool is now included in all Avateq's ATSC 3.0-enabled products.

ATSC3.0 Physical layer standard offers the most innovative techniques in signal coding schemes. The latest technology with a wide range of available operating modes allows selecting optimal modulation and coding parameters depending on the targeted and practically achievable RF channel throughput under real propagation conditions with a desired level of robustness.

The introduced innovative approach is based on dynamic estimation of the channel "link margin" as headroom for the potential limit of SNT level for the currently used modulation and coding scheme. Based on the link margin, a detailed estimation of ATSC 3.0 RF channel utilization at any point of the service area can be characterized by current and potentially achievable bitrate, spectral efficiency, and RF channel fill factor.

The developed technique suggests an alternative modulation coding scheme and configurations to maximize throughput. The suggested configurations can be used to adaptively increase the RF channel utilization by increasing the bitrate that can lead to improving QoS and more effective usage of the spectral resources, especially for stationary datacasting applications.

Experimental tests have confirmed that dynamic control based on the suggested configurations can improve channel utilization up to 30% over time by adaptively adjusting modulation and coding to dynamic changes in the signal propagation conditions. This opens new opportunities for ATSC3.0 Physical Layer to be used in novel non-broadcast applications.

By implementing link margin analytics within all its products, Avateq helps content providers and data distributors to bring ATSC3.0 datacasting to a new level by increasing the quality of service and optimizing RF channel utilization.
