RES223 – 283 – e) that the spectrum for IMT identified by WRC-07 may not completely satisfy the expected requirements of some administrations; f) that currently operating mobile communication systems may evolve to IMT in their existing frequency bands; g) that services such as fixed, mobile (second-generation systems), space operations, space research and aeronautical mobile are in operation or planned in the frequency band 1 710-1 885 MHz, or portions thereof; h) that in the frequency band 2 300-2 400 MHz, or portions thereof, there are services such as fixed, mobile, amateur and radiolocation which are currently in operation or planned to be in operation in the future; i) that services such as broadcasting-satellite, broadcasting-satellite (sound), mobile-satellite (in Region 3) and fixed (including multipoint distribution/communication systems) are in operation or planned in the frequency band 2 500-2 690 MHz, or portions thereof; j) that the identification of several frequency bands for IMT allows administrations to choose the best frequency band or parts thereof for their circumstances; k) that ITU-R has identified additional work to address further developments in IMT; l) that the IMT terrestrial radio interfaces as defined in Recommendations ITU-R M.1457 and ITU-R M.2012 are expected to evolve within the framework of ITU-R beyond those initially specified, to provide enhanced services and services beyond those envisaged in the initial implementation; m) that the identification of a frequency band for IMT does not establish priority in the Radio Regulations and does not preclude the use of the frequency band for any application of the services to which it is allocated; n) that the provisions of Nos. 5.317A, 5.384A, 5.388, 5.429B, 5.429D and 5.429F do not prevent administrations from having the choice to implement other technologies in the frequency bands identified for IMT, based on national requirements, recognizing that for some administrations the only way of implementing IMT would be spectrum refarming, requiring significant financial investment, resolves 1 to invite administrations planning to implement IMT to make available, based on user demand and other national considerations, additional frequency bands or portions of the frequency bands above 1 GHz identified in Nos. 5.341B, 5.384A, 5.429B, 5.429D and 5.429F for the terrestrial component of IMT; due consideration should be given to the benefits of harmonized utilization of the spectrum for the terrestrial component of IMT, taking into account the services to which the frequency band is currently allocated; 2 to acknowledge that the differences in the texts of Nos. 5.341B, 5.384A and 5.388 do not confer differences in regulatory status,
