Mission-critical services
Explore how personnel in public safety, utilities, rail, ports and other industries benefit from 3GPP-based push-to-x and mobile data services when migrating from legacy Land Mobile Radio (LMR) networks. Learn about future mission-critical applications, technologies and the organizational and operational aspects involved.
Explore new mission-critical services for users
Learn how public safety organizations can benefit from 3GPP-based push-to-x and mobile data services, improving everyday work operations for first responders in the field and their colleagues in the command centers. The same types of services can also be used by utilities, rail, ports, harbors, and other industries in their daily operations. Explore the value these new 3GPP-based services offer to all professionals and learn about the new services and innovations 5G can unlock.
Experience the voice quality of 3GPP-based mission-critical push-to-talk
Current LMR networks use narrowband voice, usually at 4-7kbps, providing lower voice quality than 3GPP-based narrowband 2G and 3G networks. However, voice codecs (the audio technology used for mobile voice calls) have evolved significantly since commercial 2G networks were first introduced. With 4G and 5G networks, we now have wideband HD voice and even up to HD voice+ quality. The same technology is also available in 3GPP-based mission-critical applications such as push-to-talk – ideal for use in public safety, utilities, transport and other industries.
Listen to the audio clips below to experience the quality difference between these voice codecs. Music is one of the most technically challenging examples of audio to transfer in real-time, so this is used as an example of audio shared within a voice call. It could, for example, be background music in a call queue, pre-recorded voice announcements or ambient listening during a mission-critical rescue operation.
Listen and compare mobile voice audio quality
Voice - Narrowband
Listen to narrowband (NB, 13kbps) voice for 2G and 3G mobile phones. Current LMR networks have lower audio quality than this, as the bitrate is 4-7kbps.
Voice - HD Voice
Listen to wideband voice (AMR-WB, 13kbps) for 2G and 3G mobile phones, and this is also default on all 4G smartphones and for 3GPP-based mission-critical push-to-talk.
Voice - HD Voice+
Listen to higher quality wideband voice (EVS, Enhanced Voice Services, 24kbps) for 5G (and optional for 4G) smartphones. Similar audio quality could also be enabled for mission-critical push-to-talk services in the future.
Listen and compare audio quality within calls
Audio within calls - Narrowband
Listen to narrowband (NB, 13kbps) audio within calls for 2G and 3G mobile phones. Current LMR networks have lower audio quality than this, as the bitrate is 4-7kbps.
Audio within calls - HD Voice
Listen to wideband (AMR-WB, 13kbps) audio within calls for 2G and 3G mobile phones. This is also default on all 4G smartphones and for 3GPP-based mission-critical push-to-talk.
Audio within calls - HD Voice+
Listen to higher quality wideband (EVS, Enhanced Voice Services, 24kbps) audio within calls for 5G (and optional for 4G) smartphones. Similar audio quality could also be enabled for mission-critical push-to-talk services in the future.
Migration from LMR services towards 3GPP-based mission-critical applications
What aspects should you consider when migrating your operations from Land Mobile Radio towards 3GPP-based push-to-x and enriched mobile broadband data services? What measures do you need to take to ensure service quality? Have you prepared your organization and the users?
