CHAPTER 1 Long-term planning process 1 Introduction Recommendation IT-R SM. 1047 “National Spectrum Management” adopted in 1994 recommends “that the Handbook on National Spectrum Management be used as a guide for developing national spectrum management pr

15、ogrammes.”. Chapter 3 “Spectrum Planning” of the Handbook defines long-term planning” and describes “forecasts”, inter alia, but does not propose specific procedures for Administrations to follow. This Chapter is intended to fill this gap. At present, much spectrum planning is relatively short-term.

16、 However, if spectrum resources are to adequately support national goals and objectives, long-term planning is essential. It can provide a basis for effective spectrum management to ensure that spectrum is efficiently allocated and assigned to accommodate constantly evolving spectrum requirements by

17、 new systems and their applications. It also facilitates decision-making by providing a basis for the practical consideration and evaluation of alternative courses of action. Long-term planning should endeavour to: - make todays decisions on spectrum planning strategies in view of their consequences

18、 for the future, - identi the impact of past decisions on the future, - periodically adjust decisions to changing circumstances. It should be sufficiently comprehensive to accommodate the national spectrum requirements of both known and anticipated radiocommunication systems. It also leads to: - rev

19、ision of the national table of frequency allocations, - the development of national positions on international radio conference agendas, and - revisions to spectrum regulations, policies and standards.

20、planning process The development of long-term strategies for national spectrum use will require the implementation of a national long-term spectrum planning process. This process should include the following phases: 2.1 Spectrum requirements definition Spectrum requirements definition determines fut

21、ure broad-based national spectrum requirements for ail radio services and technological, political and economic factors (see Annex 1 to this Chapter) which may influence spectrum use. Spectrum requirements can be defined on the basis of the evaluation of potential scenarios (see Chapter 2). Traditio

22、nally, spectrum use scenarios have been evaluated on the basis of consultative inputs from concerned parties including national spectrum planning organisations within governmental departments or agencies, individual user requests, and the public. Recently steps have been taken to perform scenario ev

23、aluation based on analytical modelling techniques (see Chapter 2, also applicable to the spectrum availability and spectrum option phases). 2.2 Spectrum availability The objective of this phase is to assess the availability of spectrum across all national radio services and to accommodate the spectr

24、um requirements identified in the requirements definition phase. Inputs are primarily derived from within the administration itself but also can come from the ITU International Frequency List, ITU allotment Plans and any existing regional spectrum planning studies. 2.3 Spectrum planning options The

25、aim of this phase is to develop suitable spectrum planning options to satis spectrum requirements on the basis of the data from the two preceding phases. Any analysis for the development of spectrum options would need to take account of technical, political and economic factors. The analysis would a

26、lso assess the various opportunities for services given existing and projected radiocommunication environments and/or allocations. Recommendations regarding those service requirements unable to be accommodated within current national allocations will be based on these analyses and any available spec

27、trum monitoring results. Allocation options are developed and the relative costs of any reallocation to and/or movement of existing spectrum users assessed. 2.4 Spectrum planning implementation This phase would provide for the implementation of various spectrum planning strategies (see Chapter 3) an

28、d could be expected to be an on-going process. The introduction of new services may require changes to national spectrum allocation tables and revisions to IT regulations. Revisions to international regulations would be undertaken at the various ITU World Radiocommunication Conferences (WRCs). 2.5 T

29、he iterative process Previous decisions can be re-evaluated periodically or triggere, “y specific events and, if necessary, modified on the basis of the updated information. The planning process is therefore a continuous process of exploration and data processing rather than a linear process. A reco

30、rd of all changes can be maintained to provide a history of developments in the long-term plan. STD-ITU-R RECflN SM.2OLS-ENGL 3998 W 4855232 0535470 44b m 4 Rep. ITU-R SM.2015 3 The establishment of a management or administrative body providing leadership and supervision for the implementation of th

31、e spectrum planning programme is necessary to ensure that issues relating to long-term spectrum utilisation strategies can be addressed. This will include the introduction of an early recognition system within the framework of its planning procedures. However, the body may be supported by special pl

32、anning bodies such as project groups and task forces. The management or administrative body Long-term planning is almost always a primary task at management level and one which cannot be delegated, due to the consequences and significance of the decisions to be taken. Such planning bodies are respon

33、sible for: - developing detailed strategic policies and solving problems concerning the conversion of strategic policies into operational plans; allocating financial and human resources; strategic review of procedures, results and requirements in conjunction with the implementation of strategies; an

34、y necessary recommendations concerning adjustments to organisation and management systems, and updating the planning data used as a basis for frequency management. - - - - ANNEX 1 TO CHAPTER 1 Influencing factors The following is the list of influencing factors to be considered in the long-term plan

42、pectrum manager may select from a number of methods to evaluate scenarios with respect to their potential impact on spectrum use. The evaluation of the scenarios that impact spectrum use can rely on consultative or analytical approaches or a combination of approaches. It can be very detailed, consid

43、ering all potential factors, or more cursory in its overview. STD-ITU-R RECMN SM-2015-ENGL 1998 M 4855232 0535472 219 m 6 Rep. ITU-R SM.2015 Furthermore, the responsibility for consideration of factors can be primarily that of the national spectrum manager (see also Chapter 1) or be distributed to t

44、he interested constituents. This evaluation of scenarios ultimately helps to form the basis for national spectrum manager decisions regarding spectrum allocation or regulations. A scenario is a hypothetical sequence of events, based on event and developments related to a specific field (e.g. a count

45、rys population trends), or to a specific period of time that in some manner relate to each other. A scenario is not itself a forecast but complements traditional forecasting by providing a record of a possible sequence of individual events related to one particularly interesting system aspect. Withi

46、n the framework of long-term planning scenarios are used to predict possible developments. They serve to: - increase the reliability of forecasts and interpret risks (reliability), and - identie potential strategic options. The scenarios are based on the main factors of influence, i.e. the political

47、, economic, social and technical factors. They can be developed systematically with different configurations of factors and their estimated degrees of probability. 2 The consultative approach The consultative approach is based on the premise that spectrum planners can, through collaborative proceedi

48、ngs involving spectrum users, service providers, and equipment manufacturers, arrive at a reasonably accurate and cost-effective determination of long-term spectrum requirements and use. Thus, it takes into consideration analytical and intuitive inputs from the spectrum community, placing the weight

49、 of responsibility for much of the analysis and forecasting on those who have the most at stake. The detail given to the analysis of factors is up to the user community. Given the rapid change of the radiocommunications industry and the limited resources available to national spectrum managers, such an approach often represents the best, cost-effective option for spectrum planners. 2.1 Inquiry into future spectrum/service requirements The consultative approach starts with an initial public notice or announcement, informing all interested parties that a long-term spectrum pla
