10、ices 8 8 Role of the ITU-R . 9 1 Introduction Resolution 953 (WRC-07) describes short-range devices (SRDs) as radio transmitters or receivers or both that generate and use radio frequencies locally. The Resolution describes ultra-wideband technologies (UWB), radio frequency identification devices (R
11、FID) and similar devices as short-range devices. The Resolution also recognizes that SRDs, in particular RFID, hold promise for an array of new applications that may provide benefits for users. The Resolution requests the ITU-R to study emissions from SRDs, in particular RFIDs, inside and outside th
12、e frequency bands designated in the Radio Regulations for ISM applications to ensure adequate protection of radiocommunication services. 2 Rep.

In the case of studies on UWB technology, the relevant ITU-R Recommendations and Reports are listed in Attachment A8 of Report ITU-R SM.2057 (Studies related to the impact of devices using ultra-wideband technol
16、ogy on radiocommunication services). This attachment also contains technical characteristics and protection criteria of potential victim systems. The characteristics and criteria are intended to aid interference calculations of devices using ultra wide band technology; however, they are also applica
17、ble in the study of emissions of short-range devices.

30、regulatory regimes as guidance to administrations.

Resolution 953 (WRC-07) notes all of these Recommendations in recognizing a). 5 Compatibility studies Short-range devices employ various interference mitigation techniques to achieve their performance while ensuring the protection of existing services that share the frequency band.
33、 The in-band compatibility study may be necessary only when specific frequency bands and services that require further protection, are clearly identified. This would be case-by-case study and cannot be carried out considering whole frequency bands. The following is a list of Reports that contain the
34、 results of studies done by the Electronic Communications Committee (ECC) and the European Radiocommunication Committee (ERC)1 on compatibility between existing radiocommunication services and short-range devices in specific frequency bands.
