2 BR/TSD Москва 2004 Workshop for CEE, CIS and Baltic States BCD Basis of the analysis Input data ST61 plan as on December 2003; Limited to the assignments in bands IV/V; Selected assignments with ERP 10 kW; No additional transmissions were considered;

3 BR/TSD Москва 2004 Workshop for CEE, CIS and Baltic States BCD Basis of the analysis Technical considerations Analogue assignments to be converted into digital; All assignment characteristics retained, except ERP reduced by 7 dB; No change to the assigned channel; All digital transmissions were assumed to be 16QAM, code rate 2/3; No receiving antenna directivity or polarisation discrimination for mobile and portable indoor reception; For fixed reception receiving antenna directivity and polarisation were taken into account.

4 BR/TSD Москва 2004 Workshop for CEE, CIS and Baltic States BCD Basis of the analysis Approach to the analysis Analyses were performed for fixed, mobile and portable indoor reception; Each reception mode scenario was treated separately (no mixing of the reception modes); Only co-channel interference was considered; The power sum method was used for multiple interference cases.

5 BR/TSD Москва 2004 Workshop for CEE, CIS and Baltic States BCD Basis of the analysis Technical parameters used Minimum median usable field strength values used (at MHz): 47.0 dBμV/m fixed reception; 76.0 dBμV/m mobile reception; 84.0 dBμV/m portable indoor reception. Values corrected for frequency variation by: 20log(f/471.25) fixed reception; 30log(f/471.25) mobile and portable indoor reception.

6 BR/TSD Москва 2004 Workshop for CEE, CIS and Baltic States BCD Basis of the analysis Technical parameters used continued Protection ratios: 14.0 dB fixed reception; 20.0 dB mobile reception; 17.0 dB portable indoor reception. Combined location variation values: 1.645*1.414*5.5 dB fixed and mobile reception; 1.645*2.0*5.5 dB portable indoor reception.
