New applications – new requirements:
(Mission) Critical Communications
for PPDR/Public Safety
TETRA + Critical Communications Association
How PPDR work
PPDR …
 work in „emergency“ situations
+ accidents and incendies
+ large scale events (concerts, football games etc.)
+ natural catastrophies
+ terror attacks
 are organised in groups
 are organised in hierarchical structures (command + control)
 act under time pressure
 with potentially life-threatening consequences
 in areas without network coverage
 sometimes need absolute confidentiality
TETRA + Critical Communications Association
What PPDR need to communicate I
PPDR need (among other features) …
 voice communication is paramount, but increasingly also data
 immediate access to their communication partners under any
circumstances
 Push-to-Talk (MCPTT) instead of dialing-in
 group talks
 (one talking to many / between group members)





pre-emption – access and capacity if needed
alarm – absolute priority in emergencies
DMO – using terminals without network connection
end-to-end encryption
control over their „fleets“ (rights and roles)
TETRA + Critical Communications Association
What PPDR need to communicate II
Networks used by PPDR need …
 to provide high availability under all circumstances
 to be very resilient to function during catastrophies
when other networks fail
 to provide full coverage in all areas where PPDR
might have to become active (presently the coverage
has to be permanent; deployable networks might be
helpful in the future)
 provide high degrees of security and data protection
 ideally also a low latency

What PPDR are using today
Narrowband Tetra Standard et al. that provide


Emergency button ‐ pre‐emption and priority
Group voice calls ‐ all informed talkgroups
very rapid call set‐up
good voice quality even in high noise environment
Voice plus data
Short data service / status messaging
Packet data can be concatenated
Direct Mode
gateways and repeaters
Multi‐level security
Air interface encryption
mutual authentication
remote terminal disabling
end to end encryption

PPDR Requirements discussed + processed
in ETSI + 3GPP
Functional requirements described are:
 everything that TETRA provides plus other services only
possible over a broadband bearer
 Streaming video
 Video conferencing
 Passport and biometric checks
 Ability to move the back office to the field
 Transfer of medical information
 Fire service access to hazardous materials gazetteer
 Improved automatic vehicle/person location
 Email
 Intranet browsing
TETRA + Critical Communications Association
What PPDR expect from 5G
 All functionalities they are used to in Tetra/Tetropol
environments
 Availability, coverage and reliability as in dedicated PPDR
networks
 Plus all functionalities that have been or are being
standardized in 3GPP releases.
 And on top further advantages promised by the new radio
technology, f.e.:
 high performance and resilience by default
 extremely low latency
TETRA + Critical Communications Association
Towards the Future
Mission Critical Communication is
a fast moving target:
 PPDR want to take advantage of the functionalities of the
broadband world. The more they integrate these functionalities
in their daily work the more „mission critical“ they become.
 The increasing digitalisation of sectors with high relevance to
society (transport, utilities etc., also defense) leads to an
increasing number of IT-based critical infrastructures. Their
owners have an rising interest in highly secure, efficient and
resilient infrastructures.
 In several European countries this convergence of interest has
led PPDR organisation and critical infrastructure owners to
invest in common infrastructures.
