Current PPDR Spectrum Usage

• Most relevant to TETRA PMR/PAMR

– ERC/DEC (96)01 – Emergency Services– ERC/DEC (96)04 – civil TETRA – ECC/DEC (02)03 – narrowband digital PMR/PAMR– ECC/DEC (04)06 – generic wideband PMR/PAMR decision; includes TETRA

TAPS

• Please note

– ETSI delivered ETSI TR 102 491 (06/2005) to ECC (Approved & Published) on TETRA TEDS

– ERC/DEC (96)04 includes the frequency range from 385-390/395-399.9 MHz– The NJFA 2002 (NATO Joint military/civil Frequency agreement recognizes the

possibility of having a future ECC DEC for emergency services extensions,– ETSI delivered ETSI TR 102 485 (03/2006) to ECC (Approved & Published) on

Future Wideband & Broadband Spectrum Usage

for PPDR in Europe• Wideband PPDR

– The preliminary CEPT/ECC proposal under consideration is to identify the band 380 MHz to 430 MHz as the tuning range for Wideband PPDR

• Broadband PPDR– The preliminary CEPT/ECC proposal under consideration is to identify the band

4940 MHz to 5925 MHz as the tuning range for Broadband PPDR

• Standardization– ETSI Work Items for the creation of Harmonized European Standards for WB &

BB PPDR are in progress

• User Requirements, Terms & Definitions– Report ITU-R M.2033– ETSI TS 170 001 (JPP MESA)– ETSI TS 102 181(ETSI EMTEL)

GSC: Standardization Advancing Global Communications

Terms & Definitions

• Public Protection (PP)– radiocommunications used by responsible agencies and organizations dealing

with maintenance of law and order, protection of life and property, and emergency situations.

• Disaster Relief (DR)– radiocommunications used by agencies and organizations dealing with a serious

disruption of the functioning of society, posing a significant, widespread threat to human life, health, property or the environment, whether caused by accident, nature or human activity, and whether developing suddenly or as a result of complex, long-term processes.

Note: The same Broadband DR equipment may also be used during extraordinary infrequent local incidents (PP(2) applications as described in ITU-R M.2033).

Consideration of incorporating SDR/ cognitive Functions in PPDR radio equipment (1)

• Observations made by experts in relevant ETSI technical committees

– May not improve interoperability

– PPDR communications most effective if there are minimum number of standards

– Spectrum usually congested in PPDR scenarios

– flexibility of SDR implementations generally comes at the cost of bigger, more expensive terminals which require very significantly increased power consumption

– Large and expensive terminals could restrict (economics and practicality) the deployment of such devices to personnel in the DR area that need interoperable communications.

Consideration of incorporating SDR/ cognitive Functions in PPDR radio equipment (2)

– PPDR radio equipment often provides customized features and facilities. All radios these days are defined by significant specific software - but different types of terminal don’t use the same software structure.

– The only such standard known is the Software Communications Architecture (SCA) - as supported by the SDR Forum - and that is unsuitable for the vast majority of PPDR activities.

– SDR will undoubtedly have applications for specialist groups (such as the Military) but not for general DR applications with many potential users.

• Consequences on SDR for PPDR equipment– We need to clarify that by "SDR" we mean "Standardized SDR,

with stringent standards for radio hardware, software and architecture".
