NICE, France December 5th, 2022 – 5G network innovators Accelleran, Cumucore, EURECOM and pro audio leader, Sennheiser are pleased to announce for the media and communications industries, demonstrating a latency optimized state-of-the-art private 5G network using Open RAN and Cloud Native technology with fully virtualized Core. Through extensive effort the project partners were able to significantly reduce the one-way audio streaming latency through the 5G testbed from hundreds of milliseconds at the beginning of the 5G RECORDS project down to about 10 milliseconds. Unfortunately, this does not yet meet the required fixed latency of about 1 millisecond for wireless microphone and in-ear monitoring systems in live music, which are among the most demanding applications imaginable for packet data networks. Still, high precision measurements and in-depths analysis of individual components and the end-to-end processing chain made it possible to identify bottlenecks and optimize implementations, deployments and interfaces for latency. Although some questions still remain to be answered, the work in 5G RECORDS does an important step on the way to potentially meet the requirements of a live music stage scenario with future evolution of 3GPP 5G technology.

Quote from Cumucore Mika Skarp

“We’re thrilled to be working with a world leader like Sennheiser to deliver this kind of immediately accessible, universally understandable application of a private 5G solution”, said Mika Skarp, Senior Product Manager at Cumucore. “Whereas many of our 5G deployments in critical communications or Industry 4.0 can feel somewhat esoteric to mainstream audiences, clear and comprehensible use cases like this go a long way toward humanizing 5G for the average consumer.”

Quote from Accelleran Stan Claes

“Accelleran is delighted to work alongside Sennheiser to deliver this real world, accessible Open RAN based Private 5G solution” said Stan Claes, CEO at Accelleran. “Intelligible use cases like this distinguish themselves in showing how 5G private networks bring value to a wide variety of industries – an intelligent and easily deployed private 5G solution based on an Open RAN paradigm.”

Quote from Sennheiser Dr. Jan Dürre

“The very close collaboration with outstanding mobile industry partners during the 5G-RECORDS project made it possible to explore what 5G can offer to the media industry today. Although the 5G ecosystem is not yet there for particularly demanding audio markets where lowest latency is key, we are looking forward to future developments within the mobile industry.” said Dr. Jan Dürre, research at Sennheiser.

Quote from EURECOM Prof. Raymond Knopp

“EURECOM is thrilled to have been able to collaborate with 5G-RECORDS partners on such a challenging and futuristic 5G use-case. It allowed us to ensure the interoperability of the OpenAirInterface gNodeB-DU with industry grade software from Acceleran and Cumucore and at the same time understand the limitations of current 5G technology for an application scenario as demanding as that of Sennheiser’s real-time audio processing system,” said Prof. Raymond KNOPP of EURECOM.
