ITU-R SM.1896 1 RECOMMENDATION ITU-R SM.1896 Frequency ranges for global or regional harmonization of short-range devices (2011) Scope This Recommendation contains frequency ranges to be used as recommended ranges for short-range devic
9、es (SRDs) applications requiring operation on a global or regional harmonized basis. The ITU Radiocommunication Assembly, considering a) that the 2007 Radiocommunication Assembly approved Resolution ITU-R 54 Studies to achieve harmonization for short-range radiocommunication devices (SRDs); b) that
10、there is an increasing demand for and use of SRDs for a wide variety of applications throughout the world; c) that SRD applications are deployed in both bands designated for ISM (industrial, scientific and medical) applications and bands not designated for ISM applications; d) that SRDs are not ISM
11、applications as defined in No. 1.15 of the Radio Regulations (RR); e) that, by their nature, SRDs are being used on a worldwide basis, either as an independent device or as an integral part of other systems, and are often carried and used across national borders; f) that, in some frequency bands, sp
12、ecific interference mitigation techniques may facilitate the operation of SRDs; g) that some SRDs may employ advanced spectrum access techniques; h) that using SRDs with similar technical characteristics, such as interference potential and mitigation techniques, in suitable spectrum with appropriate
13、 emission limits could enhance the coexistence of SRDs; j) that SRD applications are increasing, which may result in increasing spectrum demands (some examples are UWB, RFID, etc.); k) that it may be necessary to use the existing spectrum more efficiently and economically, further considering a) tha
14、t SRDs may create the potential for harmful interference to radiocommunication services, and some of them can be carried by individuals across national boundaries and, noting a) that Resolution ITU-R 54 states that the ITU-R should continue its studies to enable implementation of advanced technologi
15、es for SRDs, thereby in particular focusing on a strategy for the future; b) that frequency ranges, power levels and other technical and operating parameters commonly used by SRDs are listed in Report ITU-R SM.2153 Technical and operating parameters and spectrum use for short-range radiocommunicatio
16、n devices, 2 Rec. ITU-R SM.1896 recognizing a) that the regulatory framework for SRDs, such as the decision on frequency bands for use by SRDs, is a national matter; b) that there are a number of benefits of global or regional harmonization of frequency ranges for SRD usage for end users, manufactur
17、ers and regulators, such as: a broader manufacturing base and increased volume of devices, resulting in economies of scale and equipment availability; improved spectrum utilization; c) that, in principle, SRDs have no requirement for an individual licence as they generally use the radio spectrum on
18、a non-interference and non-protected basis. However, in specific cases licensing or registration may be required, recommends 1 that for SRDs requiring operation on a global or regional harmonized basis, the frequency ranges as specified in Annex 1 and Annex 2 may be considered, if appropriate. Intro
19、duction to Annexes 1 and 2 Many SRD applications and the frequency bands in which they are deployed are described in Report ITU-R SM.2153 Technical and operating parameters and spectrum use for short-range radiocommunication devices. Table 1 of this Recommendation lists common frequency bands that a
20、re used for the deployment of SRDs in all regions of the world. However, not all of these bands listed as common bands are harmonized for SRD use either globally or regionally. Annex 1 of this Recommendation indicates frequency ranges that may be globally harmonized under certain technical condition
21、s and Annex 2 of this Recommendation indicates frequency ranges that may be regionally harmonized under certain technical conditions. Further studies may need to be undertaken in ITU-R to determine whether global or regional harmonization of these ranges, or portions thereof, is feasible, given that
22、 there are many SRD applications, such as those operating across national borders, that would benefit from worldwide harmonization. Example applications of such SRDs are the following: medical applications; SRD applications used inside and outside aircraft; SRDs for supporting ID cards; some Intelli
23、gent Transport System (ITS) applications; RFID applications for luggage handling systems in airports, item management, logistics, livestock, electronic article surveillance (EAS) and near field communication (NFC). ISO and other international standardization bodies have developed standards for many
24、of these applications. Where SRDs operate in bands that are not harmonized either on a global or a regional basis, risks to radiocommunication services increase. Moreover, differences in spectrum access conditions and technical rules increase the costs to consumers of SRDs. Common frequency bands an
25、d technical rules, such as recommended power levels and mitigation techniques, should be developed in ITU-R Recommendations and Reports as guidance for national administrations. Advanced spectrum access and mitigation techniques are being developed and these techniques may allow SRDs to operate auto
26、matically within the tuning ranges that encompass frequency bands that cannot be fully harmonized throughout the Regions. For low-cost SRDs, such as RFID tags, these techniques may impose significant cost constraints and/or power limitations such as battery lifetime. Therefore, these techniques may
27、not be applicable to every SRD application. Rec.
