HYBRID BROADBAND NETWORK – Data

TETRA-digital radio for Critical Communications - Voice

Additional services via Roaming by commercial providers

Dedicated basic network with 450-MHz-spectrum

Usage of existing commercial providers` infrastructure with 700-MHz-spectrum

BDBOS – ‘Broadband Test’

The two-stage test aims to gain practical knowledge on the usability and conceptualisation of hybrid broadband infrastructure for German PPDR

Stage 1 (I+II quarter 2019): Development of detailed concept / Drafting and planning of test scenarios / Call for tender

Stage 2 (III+IV quarter 2019 & I+II quarter 2020): Implementation of test scenarios / analysis and reports on test as well as on legal, organisational und commercial aspects.

Requirements on Hybrid Networks

Public Safety first responders

• must have dedicated frequencies

• must be prioritised in a hybrid network

• must have own network slices

12.03.2019 | Slide 10A Broadband Strategy for German Critical Communications |

Public Safety Broadband Requirements

The Public Safety organizations will need enhanced and

secure broadband communications

• Real-time video and high quality pictures

• Ultra reliable communication

− Land, sea, air, in-building

− Priority over other traffic (in networks shared with other users)

• Ability for direct communication

• High security

12.03.2019 | Slide 11A Broadband Strategy for German Critical Communications |

Radio Terminal Equipment – Current Status

All Public Safety radio terminals registered in national

Public Safety network

• Certification process in accordance with national IOP policies

• Procurement for terminal equipment on a regional level

• Heterogeneous Public Safety organisations

• High effort to achieve interoperability

• Few vendors offer only limited selection of radio terminal

equipment

• Strong dependency for special equipment due to proprietary

interfaces

12.03.2019 | Slide 12A Broadband Strategy for German Critical Communications |

Radio Terminal Equipment – Future Challenges

• No standardized services in Broadband (foreign networks)

• Two different networks for Speech and Data

− Foreign use (or third party use) creates high security risk

− Foreign networks cannot be controlled or managed

− Foreign networks are not reliable

• Two different radio terminals for Speech and Data

− TETRA radio terminal

− Smartphone for Broadband (not certified, security risks)

Challenges for German Public Safety Radio

• Securing dedicated spectrum

2 x 10 MHz in 450 MHz-range in addition to

2 x 8 MHz in 700 MHz-range

• Securing overall availability

• Keeping the current security level

• Provision of sustainable network

technology

• Provision of sustainable radio terminals

BDBOS International Activities

• TCCA and ETSI member

• Active participation in LTE/5G-standardisation at 3GPP

• Exchange with PPDR network operators worldwide− TETRA experiences, e.g. handling of large scale

events− Steps towards broadband services for PPDR

• Co-Signer of the transatlantic declaration* for the international Public Safety Community
