Arqiva completes major upgrade of UK digital radio platform

Arqiva has migrated all 62 DAB multiplexes and more than 1,000 radio services onto its new Central Coding & Multiplexing System (CCMS).  

It marks the completion of a multi-year programme to modernise one of the world's most complex DAB radio networks.  

Arqiva said the new platform provides a more resilient and efficient foundation for digital radio, reducing operational risk, as well as supporting future service development.  

The programme has consolidated infrastructure previously distributed across 13 locations into two centralised sites. The entire CCMS estate now occupies just seven equipment racks, significantly reducing hardware, power, and cooling requirements.  

Arquiva said the transformation has also delivered substantial sustainability benefits. Annual electricity consumption has fallen from approximately 1,324 MWh to 168 MWh – an 87% reduction – while estimated carbon emissions have reduced from around 173 tonnes of CO₂e to 22 tonnes.  

In addition, more than 300 studio encoders across 75 sites, 200+ decoders across 100+ network distribution sites and over 100 racks of legacy equipment are being decommissioned and recycled through certified partners.  

Arqiva previously delivered the Digital Switchover Project, which brought digital terrestrial TV to UK homes. Alongside this, the company has a large stake in the smart utilities network sector, with around three million smart energy and water meters installed. 

Dom Wedgwood, Chief Technology Officer at Arqiva, said: "Digital radio remains a critically important platform for broadcasters and listeners across the UK, and this programme represents one of the most significant transformations of our radio infrastructure in recent years. 

"Completing the migration of all 62 multiplexes and more than 1,000 services onto our new platform strengthens the resilience and future-readiness of the UK's DAB network, while delivering substantial improvements in efficiency and sustainability. 

"For our radio customers, this means a more robust, efficient and future-ready platform for the services they rely on us to deliver every day. It demonstrates how targeted investment in our technology can modernise essential communications infrastructure, reduce environmental impact and create a strong foundation for the future of digital radio services." 

Macquarie Asset Management recently agreed to the sale of its 26.5% stake in broadcast infrastructure firm Arqiva for £16.5m. Discover more here.
