3. Date | Title of presentation | 3 Driving factor is fear and uncertainty of people. Measurements can create a basis for discussion, which people can understand and trust. Key issue are credible, comprehensive results. Different results and criteria apply for different groups. Otherwise the risk is growing concerns and influence of others. Example for an Successful Risk Communication community of highly concerned undefined concerns indifferent ambiguous Segmentation of EMF awareness Influence

6. Date | Title of presentation | 6 Community of highly concerned l Results must be traceable l Detailed information on measurement conditions l Results must endure comparison with third party measurements l Results for different frequencies and services with evidence of also smaller emissions must be available Proof of correct and traceable measurements Ability to show results for specific investigations Measurement Criterias

7. Date | Title of presentation | 7 l Installation conditions l Ruggedized design and easy installation l No experts needed for putting into service l Easy to cover large areas l Conditions for the results l Surpassing repeatability and traceability of the results. l Possibility of central database with directly comparable data. l Measurement of the actual immission, no extrapolation New technologies (e.g. MIMO) make extrapolation difficult anyway. l Longterm evaluation allows correlation with public discomforts. l Longterm evaluation can prove any transmitter changes. l Realtime results prove authenticity. l The trustworthiness has to be proven only once. Measurement failures can be minimized. Benefits of Automated Longterm Measurements
