9、Question ITU-R 48-6/5) (2005-2012) Scope This Recommendation documents the technical and operational characteristics of systems used in the amateur service and amateur-satellite services for the purposes of carrying out sharing studies. The systems and their characteristics described in this Recomm
10、endation are considered representative of those operating in the frequency bands available to these services ranging from 135.7 kHz through 81.5 GHz. The ITU Radiocommunication Assembly, considering a) that the Radio Regulations (RR) defines an amateur service and an amateur-satellite service and al
11、locates frequencies to them on an exclusive or shared basis; b) that systems in the amateur and amateur-satellite services operate over a wide range of frequencies; c) that the technical characteristics of systems operating in the amateur and amateur-satellite services may vary within a band; d) tha
12、t some ITU-R technical groups are considering the potential for the introduction of new types of systems or services in bands used by systems operating in the amateur and amateur-satellite services; e) that representative technical and operational characteristics of systems operating in the amateur
13、and amateur-satellite services are required to determine the feasibility of introducing new types of systems into frequency bands in which the amateur and amateur-satellite services operate, recommends 1 that the technical and operational characteristics of systems operating in the amateur and amate
14、ur-satellite services described in Annex 1 should be considered representative of those operating in the frequency bands allocated to the amateur and amateur-satellite services; 2 that Recommendation ITU-R M.1044 should be used as a guide in studies of the compatibility between systems operating in
15、the amateur and amateur-satellite services and systems operating in other services. * This Recommendation should be brought to the attention of Radiocommunication Study Group 1. 2 Rec. ITU-R M.1732-1 Annex 1 Characteristics of systems operating in the amateur and amateur-satellite services for use i
16、n sharing studies 1 Introduction A number of frequency bands are allocated to the amateur and amateur-satellite services throughout the spectrum. These bands have been selected to provide different propagation conditions. Amateur and amateur-satellite stations perform a variety of functions, such as
17、 training, intercommunication between amateur stations and technical investigations by duly authorized persons interested in radio technique solely with a personal aim and without pecuniary interest (RR Nos. 1.56 and 1.57); disaster relief communications as elaborated in Recommendation ITU-R M.1042
18、 2 Operational characteristics Amateur stations and amateur-satellite earth stations generally do not have assigned frequencies but dynamically select frequencies within an allocated band using listen-before-talk techniques. Terrestrial repeaters, digital relay stations and amateur satellites use f
19、requencies selected on the basis of voluntary coordination within the amateur services. Some amateur frequency allocations are exclusive to the amateur and amateur-satellite services. Many of the allocations are shared with other radio services and amateur operators are aware of the sharing limitati
20、ons. Communications may be initiated on prearranged schedule or by one station initiating a general or specific call. One or more stations may respond. Formal and informal nets may be initiated as needed. Contacts may last from about 1 min to about 1 h, depending on traffic to be transmitted. Operat
21、ing protocols vary according to communication requirements and propagation. MF and HF bands are used for near-vertical-incidence-sky wave to global paths. VHF, UHF and SHF bands are used for short-range communications. Amateur satellites afford an opportunity to use frequencies above HF for long-dis
22、tance communications. 3 Technical characteristics Tables 1 to 6 contain technical characteristics of representative systems operating in the amateur and amateur-satellite services. This information is sufficient for general calculation to assess the compatibility between these systems and systems op
23、erating in other services. The upper frequency boundaries shown in Tables 1 to 6 represent the current state of deployment of most amateur radio systems. The characteristics are expected to be extended to higher frequencies (up to 250 GHz) over time. Rec. ITU-R M.1732-1 3 TABLE 1 Characteristics of
