4. Meet ST61COORD software RRC Workshop for CEE, CIS and Baltic States, Moscow 21-24 Sept 04 Modification - Exclusive bands Consult affected administrations Distances from the stations to the nearest points of the boundaries Provide proposed technical characteristics so that affected administration can assess the probability of harmful interference Affected administrations to reply within ten weeks If not, notifying administration will send a reminder

5. Meet ST61COORD software RRC Workshop for CEE, CIS and Baltic States, Moscow 21-24 Sept 04 Modification - Exclusive bands (2) Affected administrations to reply within two (2) weeks If not, considered to have agreed to the proposed change No agreement is reached, BR may be requested to make technical examination and inform administrations of the results

6. Meet ST61COORD software RRC Workshop for CEE, CIS and Baltic States, Moscow 21-24 Sept 04 Modification - Exclusive bands (3) Modifications without consulting if Reduction in power or changes that would reduce the probability of harmful interference OR Distances to nearest points of the boundaries are equal or greater than the coordination distance limits

7. Meet ST61COORD software RRC Workshop for CEE, CIS and Baltic States, Moscow 21-24 Sept 04 Modification - Exclusive bands (4) Notify administration inform BR Proposed modifications Names of administrations consulted, where appropriate. BR publish in Part B of a Special Section

8. Meet ST61COORD software RRC Workshop for CEE, CIS and Baltic States, Moscow 21-24 Sept 04 Modification - Shared bands Notify administration informs BR of technical information BR publishes in Part A of a Special Section Comment period = 12 weeks Comment should be sent DIRECTLY to notify administration No comment shall be considered to have agreed to the proposed changes

9.

10. Meet ST61COORD software RRC Workshop for CEE, CIS and Baltic States, Moscow 21-24 Sept 04 Coordination distances Coordination distances are determined base upon Operating frequency bands, I to V Effective radiated power Effective transmitting antenna height Nature of the path

11. Meet ST61COORD software RRC Workshop for CEE, CIS and Baltic States, Moscow 21-24 Sept 04 Coordination distances (2) Power <> values given linear interpolation shall be used Heights <> values given next higher height shall be used Percentage of sea path <> values given Next higher percentage shall be used Effective height > 1200 m or no limiting distances given Procedure of shared bands applies.
