Aim of NEDDIF creation
The main aim of the NEDDIF is to consider a common approach to the band 790 – 862 MHz usage and frequency coordination and to exchange views and experiences.
ITU Regional Development Forum and Seminar, Warsaw,

4. NEDDIF - Terms of reference
The NEDDIF group was created to facilitate the frequency coordination for digital dividend implementation in 800 MHz band, with a view to:
achieving mutual compatibility of the spectrum resources to be used in the implementation of the digital dividend in each country,
finding solutions for more effective cross-border coordination including specific cross-border coordination with non-EU countries with different use of spectrum,
ITU Regional Development Forum and Seminar, Warsaw,

5. NEDDIF - Terms of reference
... and
facilitating any consequential modifications to the GE-06 Plan, taking into account relevant future developments and respect principle of equitable access to spectrum resources.
The NEDDIF Group works on the consensus basis
ITU Regional Development Forum and Seminar, Warsaw,

6. Considered problems (main)
Frequency usage by ARNS systems in North-Eastern Europe ( MHz frequency range),
Compatibility criteria between ARNS and mobile ECS in the Digital Dividend band (theoretical and experimental),
Propagation models (theoretical and experimental),
ITU Regional Development Forum and Seminar, Warsaw,

7. Considered problems (main) - cont.
Possibility of rearrangement of channels used by ARNS systems (re-channelling in MHz band),
Impact of geographical distribution of ARNS systems on Digital Dividend implementation,
Cumulated impact of mobile ECS networks for ARNS systems (theoretical and experimental),
ITU Regional Development Forum and Seminar, Warsaw,

8. Considered problems (main) - cont.
Date of switching off ARNS systems in some NEDDIF members,
Incentives to give up frequencies by ARNS users (refunding models).
ITU Regional Development Forum and Seminar, Warsaw,

9. Considered problems (main) - cont.
Frequency usage by ARNS systems
RLS 2 (ground radar transmitter – aircraft responder) MHz,
RSBN (aircraft transmitter – ground radar receiver) MHz,
RLS1 (ground radar transmitter – ground radar receiver) MHz
ITU Regional Development Forum and Seminar, Warsaw,

10. Considered problems (other)
Related to potential re-channelling of frequency positions with channels above 60,
Related to the roll-out of ECS in 790 – 862 MHz (e.g. compatibility at the band edge, protection of digital broadcasting, rechanneling of PMSE use),
New approach to frequency coordination for broadcasting (e.g. potential areas per channel, preferential channels).

11. ITU Regional Development Forum and Seminar, Warsaw, 7-9.05.2012
Results
Modification of propagation model (Latvian proposal to the ITU Study Group 3),
Empirical Assessment of protection criteria between ARNS and LTE (Polish measurements concerning compatibility between LTE system and RSP-10 MN-1 radar system),

Assessment of aggregated level of harmful interference (Latvian measurements and Polish simulations concerning cumulative field strength generated by mobile network),
Meeting between NEDDIF members and BLR, RUS and UKR,
Agreement of Belorussia, Russia and Ukraine to become members of the NEDDIF Forum,
ITU Regional Development Forum and Seminar, Warsaw,

13. ITU Regional Development Forum and Seminar, Warsaw, 7-9.05.2012
Results (cont.)
... and
Signing bilateral agreements on the use of 800 MHz band for terrestrial systems between some NEDDIF members and BLR, RUS and UKR,
Good cooperation during WRC-12 on Agenda item 1.17 and other issues concerning with the Digital Dividend band.
ITU Regional Development Forum and Seminar, Warsaw,

14. ITU Regional Development Forum and Seminar, Warsaw, 7-9.05.2012
Future plans
Continuation of works concerning with the Digital Dividend implementation,
Start of activities concerning with the second digital dividend (700 MHz band).
