This Recommendation gives guidelines for spectrum redeployment issues. The ITU Radiocommunication Assembly considering a) that all administrations need to make spectrum available for new radio applications and for increased use of existing applications; b) that as the use of the spectrum increases it may become progressively more difficult for administrations to find suitable spectrum for radio applications; c) that making spectrum available for some new applications may require redeployment to other frequency bands or redeployment to new technologies (i.e. to decreased bandwidth or analogue to digital); d) that redeploying licence-exempt bands will be complicated by lack of records of users; e) the experiences of administrations in spectrum redeployment techniques would provide information on the practice; f) that frequency management and thus redeployment of spectrum is a national responsibility and there is a need for guidelines by collating the experiences of administrations in spectrum redeployment techniques.
