In addition, it also shows that if the wideband system were to be CEPT aligned there would be an improvement. abc
Appendix G: Spectrum Trading and Liberalisation Modelling G.1 Method All co-channel users within grid referenced 50km squares were removed. No users outside the 50km squares exceeded -116dBm (This is equivalent to 12dBuV/m assuming a 0dBd antenna) in a 12.5 KHz band at 1.5m agl for 50% time at the 50km square border. 240689 - 450-470 Study Final Print Version (Dec08).doc Area of interest with 50 x 50km square trading areas The picture above shows the Thames Gateway modelling area with its associated 50km trading squares. The broadband system was modelled to cover only the selected Thames Gateway area (pink area). In addition the wide band systems were modelled to be within the 50km trading zone and meet the criteria at the trading zone border. As shown below.
