ITU-R conducted sharing studies related to the candidate bands to determine the suitability of the candidate bands for IMT identification. This Report assesses the feasibility of sharing between IMT systems operating in the 450-470 MHz band and the radiocommunication services having a primary allocation in Section IV of Article 5 of the Radio Regulations – Table ofFrequency Allocations (henceforth referred to simply as the Table) in the 450-470 MHz band and in the adjacent 420-450 MHz and 470-480 MHz bands. This study addresses onemember of the IMT family, i.e. IMT-2000 CDMA Multi-Carrier (CDMA-MC).For ease of reference, CDMA-MC operating in the 450-470 MHz range is referred to as CDMA450 throughout the document. Further revisions of this Report may include other technologies in the IMT family.
