This Annex gives information about the ground conductivities in various areas of the world, in theform of a World Atlas of Ground Conductivities. This information is intended to be used for fieldstrength predictions in connection with the ground-wave propagation curves contained inRecommendation ITU-R P.368.

In transmission engineering, most often it would be rather impractical to characterize the magnitude of signals directly by a numerical value in volts or watts. Instead, a logarithmic measure is used, expressed in "dB", to characterize the signal magnitude in relation to some chosen reference value.

Current technology allows most spectrum monitoring functions, and indeed entire monitoring stations, to be highly automated, and allows spectrum monitoring systems to be highly integrated with automated spectrum management. Many activities of an automated national spectrum management system will benefit from integration with automated spectrum monitoring stations. This Recommendation describes recommended functionality of these systems.

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.
