• We offer the DRM digital radio broadcasting standard for Band III and for the FM Band.

• Based on several crucial implementation aspects such as spectrum usage, Capex, Opex, implementation flexibility, growth, power resources and ‘use as you grow’ features, you will find DRM system much more beneficial.

Alexander Zink Vice-Chair DRM Consortium; Senior Business Development Manager, Fraunhofer IIS FM Radio: Malaysian Situation

Challenges to analogue FM broadcasting: • Major competition from digital media for user attention • Perceived old-style media, audio-only services • Declining revenue from classic ads • Often a public mandate to maintain broadcast networks (emergencies)

But still: • Leading media for in-car consumption • Trusted information source • Very limited competition in every location (comp. to millions of web streams) Which Digital Radio Standard?

Digital Radio Standard must allow for easy migration: • Use existing frequency spectrum • Utilise existing technical infrastructure – transmitters, feeder lines, towers, etc. • Capable of simulcast operation (analogue + digital) during transition period • To be non-proprietary • Work in all broadcast bands – SW, MW and FM Why DRM for Digital FM Radio

• Most recent global digital radio standard in all the VHF bands: Band I, Band II (FM-Band), Band III

• Endorsed by the ITU in 2011 ITU-R Rec. BS.1114 (system), ITU-R Rec. BS.1660 (planning parameters) • ETSI standard ratified in 2011 • Worldwide spectrum compatibility: 96 kHz bandwidth (half of FM) • Useful content bit rate: 37—186 kbps • Flexible configuration: capacity  coverage  transmission power • Significant Cost Savings: Green and energy efficient • Transition path for established FM networks The Solution: Digitising FM Radio!

How effective is it?

And how can Digital Radio support this task in future? Source: http://sdg.iisd.org/news/international-disaster-database-61-7-million-impacted-by-disasters-in-2018/

Extreme weather conditions often come with a pre-warning phase.  Are we already getting the most out of this time window to warn the public and save lives? • Ubiquitous: Oldest and largest available media platform worldwide (everywhere there are radios in their millions that can be easily used, even independent of energy sources e.g battery…) • Quick Access: Guarranteed to reach everyone, even sparse populations in the furthest corners of territories/countries. Able to offer through the power of terrestrial broadcasting (“one to many”) full country coverage • Resilient: when disaster strikes, the one platform guaranteed to function. Radio - the last line of resistance in front of disaster • Easy to Integrate: Proven paths of access from disaster agency/government triggering the alarm to studio-transmitter- listener/affected population • Part of integrated system: can be part of integrated national system (TV. Mobiles etc.) and support all Emergency Warnings Issues with Analogue Radio Transmissions?

• Emergency program replaces the normal program • Radio listeners in the entire coverage area of the transmitter get only emergency program even if disaster in a limited area • No alert signaling • No auto tuning of receivers to emergency programs • No text information in local language Detection of pending Disaster disaster hits
