GatesAir, a provider of wireless, over-the-air content delivery solutions for radio and TV broadcasters, has delivered turnkey China Digital Radio (CDR) systems to the Guangdong Broadcast Bureau technical centre in Guangzhou city.

 The initial deployments include four GatesAir Flexiva™ high-efficiency transmitters to support the national roll-out of digital radio in China.

The GatesAir solution will support both IP and ASI transport to move audio and data to transmitter sites across the Internet and satellite networks, leveraging CDR versions of its Flexiva software-defined exciter and exclusive RTAC™ real-time adaptive correction system to optimize digital signal performance. 

The system additionally integrates GatesAir’s innovative hybrid crest factor reduction technology to increase power output, optimizing signal coverage in the Guangdong province.

China Digital Radio is an FM in-band, on-channel (IBOC) digital radio system capable of delivering a large multiplex of audio (analog FM and digital) and rich data services, including news, traffic and other local and national information.

GatesAir is working with The State Administration of Radio, Film and Television (SARFT)’s Academy of Broadcasting Science as well as regional broadcasters across China during the early planning and design phases.

It is the only supplier outside of China to support China Digital Radio.

“The sophistication and quality of our China Digital Radio solution directly correlates with our extensive experience across all digital radio standards worldwide—a key factor in SARFT’s selection of GatesAir as a trusted China Digital Radio supplier nationally,” said Rich Redmond, Chief Product Officer, GatesAir. “The flexibility of the China Digital Radio standard—which includes hybrid FM/digital delivery, multicasting and wide-area IP networking—means that the future is wide open when it comes to the possibilities of digital radio in China. We are excited to be an integral part of this digital transition.”
