ITU-R REPORT SM.2154

Abstract

<strong>Introduction</strong> <br>Industry request more licence exempt frequency space under the argument that the available frequency bands are not sufficient and sometimes even congested. A balanced opinion from a frequency management point of view can only be obtained when this is based on objective information, including spectrum monitoring information. Also many non ISM bands used by different services are nowadays occupied by short-range radiocommunication devices (SRDs) sharing these frequencies under no interference no protected basis. This Report does not describe UWB or UWB related measurements. <br>Typical values given in the Report are based on the example of a 863-870 MHz monitoring campaign. For other frequency bands and SRDs in those bands, other values may be more appropriate without changing the basic measurement methodology.
