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

� LDACS

� PMSE?� Support spectrum access for GNSS

Can we get more spectrum?.... NO!Hence we shall increase spectrum efficiency (Cf. ITU rules)

� Frequencies for voice and data communications between pilots and controllers.

RFF objectives:

1.Minimise impact of congestion

2. Ensure 8.33 benefit lasts

First Solution: What does the RFF do?

� The RFF supports States in� satisfying frequency requests

� keeping frequencies working safely

� ensuring we all work to high standards

� preparing for aviation evolution

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.
