Definition for PMSE• Services Ancillary for Programme-Making (SAP) • Services Ancillary for Broadcasting (SAB)• Electronic News Gathering (ENG) and Outside Broadcasting (OB)• Electronic News Gathering (ENG) and Outside Broadcasting (OB)

As defined in ERC Report 38 and ERC Report 42 (see also ITU-R Report BT.2069 and ECC Report 002) including wireless production tools used for front-end solutions (audio, video, data) in the field of professional multimedia production (from

di d t l i i t t lt f t d f i t t i t li ti d ti t t d hradio and television to art, culture, conferences, trade fairs, entertainment applications, education, sport events and much more).

Examples for PMSE Components:Examples for PMSE Components:• Video cameras• Microphones • In ear monitors• In-ear monitors • Conference systems• Intercom devices

Data links (e g for remote control)

Ch llChallenges

Spectrum Scarcity (PMSE operates mainly in 470-862 MHz)p y ( p y )• Digital Dividend in Germany: PMSE lost 72 MHz of spectrum, 790-862 MHz• (Digital Dividend II: Under discussion for Public Safety Services and other)• More Digital TV (DTV) Transmission: DVB T and DVB T2 in parallel• More Digital TV (DTV) Transmission: DVB-T and DVB-T2 in parallel• PMSE: more events, more productions, higher quality in video and audio

Existing Coexistence of PMSE with• Analogue / Digital TV Transmission• Cellular Mobil ServicesCellular Mobil Services• Radio Astronomy• Other PMSE

• Potentially new challenge: New kinds of TV Band Devices (ECMA-392, IEEE 802.11af, IEEE 1900.7) with unpredictable radio transmission

Obj ti f C PMSE P j t 1/3Objectives of C-PMSE Project 1/3

R&D on the cognitive system and procedures for PMSE• Development of system components, like antennas, scan receiver, scan controller,

cognitive engine, data base and so on.• Measurement- and test procedures as well as channel-, interference- and co-existing

models as reference for the standardization and regulation activities




Field trial platform

• Setting up a field trial platform for cognitive PMSE applications at the ppfair grounds of Messe Berlin

• Technical and economical proof of concept of the cognitive methods for PMSE

• Realizing an open and modular R&D platform for future research

Frequency regulation and standardization• Setting up a forum to discuss and prioritize necessary actions concerning cognitive

PMSE on national, European and worldwide level• Active collaboration in meetings of ITU, ETSI, CEPT/ECC and Bundesnetzagentur by

using the project results and the preparatory work of the Specialist Task Force ETSI STF 386

ITU R D fi iti C iti R di S t (CRS)ITU-R Definition: Cognitive Radio System (CRS)

A radio system employing technology that • allows the system to obtain knowledge of its operational and geographical

environment, established policies and its internal state; • to dynamically and autonomously adjust its operational parameters andto dynamically and autonomously adjust its operational parameters and

protocols according to its obtained knowledge in order to achieve predefined objectives;

• and to learn from the results obtainedand to learn from the results obtained.

R i t f th C PMSE S tRequirements of the C-PMSE System

Automation of spectrum grant and spectrum access processes Adjustable system parameter for the frequency utilization, free-/occupied recognition,

adaptable transmission parameter during operation, compatible with traditional frequency access mechanisms (duty cycle, detect and avoid, listen before talk, ask before talk, …)

Securing a coordinated coexistence of different users in the same frequency range

Coexistence with a traditional PMSE systems and with other CR Systems, avoidance of interferences, continuous quality surveillance of the transmitted signals, surveillance of the frequency spectrum condition, emergency management in case of frequency interferences

Efficient frequency utilization Increase of the efficiency of frequency utilization and frequency allocation compared to

traditional PMSE-systems

Scalability to cover all use casesy Modular system concept
