In addition: Multiple users of the frequency bands
� Multiple systems in the DME band (960 – 1215 MHz):
� SSR
� UAT
� GNSS
� In the future: LDACS
� Military systems: TACAN, JTIDS/MIDS
� More systems in the future

First : Manage the spectrum efficiently: DONE with the RFF.Second : Reduce Channel Spacing: The introduction of 8.33 kHz channels
- European Commission regulation : 1265/2007, 1079/2012.
� 8.33 channel spacing deployment in EUR region
� In 1999: Above FL245
� In 2007: Above FL195
� In 2014/2018: Below FL195?

Conclusion
� Current solutions can solve the problems, but implementation delays may have network
impact
� -> 8.33 implementation must be implemented as planned.
� -> Risk: Gap between planning and real implementation
� Newcomers to the aeronautical spectrum can significantly worsen the situation and fast
� Changes to aeronautical systems expensive and slow
� Very long ROI, therefore no investment.
� Spectrum is a scarce resource, aviation need to continue to invest to optimise its usage.� Airport communication (AeroMACS etc…)
� LDACS.
