Key Takeaways

  • Henry Cohen, Senior RF Engineer at CP Communications, evaluated Shure Axient Digital Wireless Systems during major televised sports broadcasts in challenging, high-channel-count RF environments.
  • As available UHF spectrum continues to shrink, Axient Digital helped address key challenges around wireless reliability, spectral efficiency, and RF performance.
  • The system's Quadversity™ technology simplified coverage management across large RF zones, improving workflow efficiency during complex live productions.
  • Cohen highlighted Axient Digital's signal robustness and spectral efficiency in both standard and high-density operating modes.
  • For CP Communications, Axient Digital delivered the combination of wireless microphone performance, workflow advantages, and future-ready scalability needed to succeed in increasingly congested spectrum environments. 

CP Communications is a full service RF production provider for major sports and special events broadcasting. With the 600 MHz UHF spectrum being significantly reduced, and the 500MHz band experiencing repacking of the remaining DTV broadcasters, finding robust, reliable wireless solutions is a critical need.  

To evaluate performance in these demanding conditions, Senior RF Engineer Henry Cohen tested a four-channel Shure Axient Digital Wireless System during two major televised sporting events in large urban markets. These required high RF channel counts across a multi-zone distributed antenna system.

Cohen found the Axient Digital platform very promising for its spectral efficiency, and for its new Quadversity antenna capability, which allows four antenna inputs into its receiver.

Customer Profile

  • Better workflow efficiency for complex RF deployments 

Why Axient Digital Stood Out 

Cohen found the Axient Digital platform particularly promising for its spectral efficiency and Quadversity antenna capability, which allows four antenna inputs into a single receiver. 

“Quadversity is a powerful feature. It proved very useful in executing a large RF coverage area,” notes Cohen. 

“Often, balancing coverage areas for overlapping target zones is a real-time effort, adjusting sensitivity and turning zones on and off as needed during the event. Quadversity eliminates a lot of that activity, making for a much improved work flow, which was invaluable.”

For large-scale broadcast productions operating across multiple coverage zones, simplifying antenna management can deliver significant workflow benefits while helping maintain consistent wireless performance. 

Performance in Challenging RF Environments 

Cohen was also impressed with the Axient Digital RF performance, which benefits from a new digital radio with improved sensitivity for operation above today’s higher noise floors.  

Henry notes: “The digital RF system in this product is vastly improved, surpassing other Shure products as well as competitors in both signal robustness and spectral efficiency in both regular and ‘high density’ modes.” 

The combination of improved RF performance and spectral efficiency helped demonstrate the platform's ability to support high-channel-count wireless microphone deployments in demanding broadcast environments.

Built for the Future 

Overall, Cohen found that Axient Digital will thrive in the difficult RF scenarios that CP Communications is constantly faced with.  

He also appreciates the fact that the Axient Digital receivers he buys now will be fully compatible with the advanced ADX series transmitters that Shure will ship in early 2018.

“The system has a great design, feature set, and build quality. Its integration of improvements and new features provide a real workflow advantage.”  

“All things considered, the new Axient Digital system is the best option in wireless microphone products coming to market to cope with reduced and more congested spectrum.”
