18
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 Band IV and V – Your results
19
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 Analysis – Impact of OS and BC Case 1 – OS and BC – 104569 available channels identified Case 4 – No OS and No BC – 407602 available channels identified OS and BC consume nearly ¾ spectrum available 2 coverage is expected if taking OS and BC into account
20
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 Band III - Case1 (OS and BC) 9582 requirements for synthesis 4474 (~47%) without available channels => not assigned with a channel. –Some of these may be submitted with one or few acceptable channel. 2.7 available channel for each requirement 25 incompatibilities for each requirement
21
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 Band III - Case1 (OS and BC) 9582 requirements for synthesis 330 (3%) have no incompatibility 4067 (~42%) with 1 available channel and between 1 to 214 incompatibilities –If many incompatibilities => unlikely assigned with a channel As many as 227 IC for a requirement
22
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 Band III – Case 4 (No OS/BC) 9582 requirements for synthesis 991 T-DAB with 32 available channels 6 available channels for each requirement 75 ncompatibilities for each requirement As many as 607 ICs for a requirement
23
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 Band III – Case 4 (No OS/BC) 9582 requirements for synthesis All requirements have at least 1 AC 1678 – No IC => get a channel 1665 – only 1 AC => get a channel => coordinated well 5962 (~63%) with 1 available channel and between 1 to 379 incompatibilities –If many incompatibilities => unlikely assigned with a channel
24
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 Band IV/V - Case1 (OS and BC) 38602 requirements for synthesis 13534 (~35%) without available channels => not assigned with a channel. –Some of these may be submitted with one or few acceptable channel. 1081 with 49 available channels
25
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 Band IV/V - Case1 (OS and BC) 38602 requirements for synthesis 3274 (<10%) have no incompatibility 18881 (~49%) with 1 available channel and between 1 to 300 incompatibilities –If many incompatibilities => unlikely assigned with a channel
26
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 Band IV/V – Case 4 (No OS/BC) 38602 requirements for synthesis 7207 with 49 available channels Each AC requested by 7800-8400 requirements – evenly requetsed
27
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 Band IV/V – Case 4 (No OS/BC) 38602 requirements for synthesis All requirements have at least 1 AC 11948 – No IC => get a channel 11866 – only 1 AC => get a channel => coordinated well 28521 (~74%) with 1 available channel and between 1 to 1170 incompatibilities –If many incompatibilities => unlikely assigned with a channel
28
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 Results in RRC countries High percentage of requirements assigned with channels –coordination activities –Administrative declarations Areas where channels not assigned <= protection of analogue services (unintended) Some border areas – low success rate need more studies
29
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 Elements impact on the results Excessive input requirements for the available spectrum and errors in the preparation and submission of input requirements by administrations Internal incompatibilities between requirements and existing assignments/requirements (from the same countries)
30
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 More important element.. Modification to planning software to enable some intervention in the random approach in the synthesis process => equitable access Very high transmitter power assignments (sometimes linked with allotments)
31
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 More important elements… Submissions of administrative declarations, both internal and with neighbouring countries which can, for example, take account of realistic terrain features.
32
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 Less important elements Test points/reference networks in the sea Assignments and/or allotments for very large service areas
33
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 How many coverage? in Band III, sharing between T-DAB and DVB-T services, a possible target could be one (1) DVB-T and three (3) T-DAB in Bands IV and V, a nominal target of 6-7 layers may be possible; in areas of extreme propagation conditions, the number of layers is expected to be less;
34
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 One recommendation First - identify areas where there are a large number of incompatibilities Consider how to resolve these incompatibilities. This was found to an effective planning approach by some administrations.
35
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 Plan for very large service area assignments/allotments? consider the potential of self interference and interference to the neighbouring areas; combination of small and large allotments in the same geographical area is likely to result in unbalanced distribution of channels; the size of an allotment area should generally be slightly greater than the co- channel reuse distances
36
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 Three sure ways to achieve better results 1.Coordination 2.Negotiation 3.Coordination and Negotiation
37
RRC information meeting and workshop - Damascus, Syria 16-18 August 2005 Thanks for your attention
