What is Digital Radio?

Digital radio is a modern broadcasting format designed to deliver high-quality and stable audio content. Unlike analog radio (FM/AM), digital radio provides clear, noise-free sound while offering advanced technological capabilities.

One of the most widely used and effective standards for digital radio broadcasting is DAB+ (Digital Audio Broadcasting Plus), which offers several advantages:

• Wider coverage and continuous signal – DAB+ networks can be designed to provide consistent and wide geographic coverage without the need to switch frequencies. This is particularly important for uninterrupted listening while driving, as users can continue listening to the same station across long distances without needing to retune.
• High-quality and stable audio – Listeners within the coverage area receive a consistently high-quality sound, unaffected by noise or signal degradation.
• Transmission of additional data (metadata) – DAB+ broadcasts include a data stream that allows the transmission of supplementary information such as the program name, song title, artist, album cover artwork, and other metadata alongside the audio.
• Emergency Alert System – The DAB+ digital radio system incorporates emergency alert capabilities, allowing public authorities and relevant services to reliably and efficiently notify the population about imminent or ongoing emergencies.
• More programs on a single frequency – With DAB+, a single transmitter can serve multiple radio stations on the same frequency, without mutual interference.
• Efficient broadcasting infrastructure – DAB+ networks are more flexible and easier to manage and maintain, as they broadcast multiple channels simultaneously through a multiplex (ensemble).
• Energy efficiency – Digital radio broadcasting networks are more energy-efficient. Experience from many countries shows that DAB+ transmitters consume significantly less electricity than an equivalent FM network for the same coverage area.
• Development and availability of receivers – In recent years, the market has seen an increase in the availability of various DAB+ receivers, from small tabletop radios for home and office use to integrated multifunctional media systems in cars.

On May 6–7, 2025, the “Digital Radio Perspective in Armenia” workshop was held in Yerevan with the aim of clearly defining the strategy for implementing the DAB+ digital radio program. The workshop was organized by the Ministry of High-Tech Industry of the Republic of Armenia, the Television and Radio Broadcasting Network of Armenia CJSC, and the international organization WorldDAB.

The workshop brought together both local and international experts in the field of radio broadcasting. Among the invited speakers were Lindsay Cornell, Chair of the WorldDAB Technical Committee and Principal Systems Architect at BBC Digital, and William Jackson, Communications Manager at WorldDAB.

Throughout the workshop, participants discussed the current state and future vision of radio broadcasting in Armenia, the technical capabilities and benefits of DAB+ technology, and the main stages of its implementation.

Attention was also given to spectrum planning, the application of international best practices, and the development of an appropriate legal and regulatory framework.

The advantages of implementing the Automatic Safety Alert (ASA) system were also discussed, as well as strategies for ensuring the accessibility and distribution of DAB+ receiver devices.

The workshop was highlighted as a key platform for identifying current challenges in the sector, exchanging international expertise, and strengthening cooperation.

As a result of the workshop, it is expected that the invited international speakers will submit their written recommendations and expert conclusions regarding the sequencing, phased implementation, and upcoming steps for the introduction of digital radio broadcasting in Armenia. These recommendations will serve as an important guide for organizing the digital radio transition process in a structured and goal-oriented manner.
