The radio frequency spectrum is a vital and limited national resources. In today's era of modern broadcasting and communications, Spectrum contributes to medical service, public welfare, transportation infrastructure, public safety, job creation, and economic growth, and it enables us to promote ubiquitous information society. Moreover, radio spectrum is a 'key resource' for a number of essential service, e.g. mobile, wireless and satellite communications, TV and radio broadcasting, transport, radio location (GPS: Global Positioning System), scientific applications (meteorology and weather satellites, earth observation, telemetry, radio astronomy and space research), and various other applications, such as alarms, remote controls, medical equipment, e.g. implants and hearing aids. Radio technologies also support and sustain 'public services' of prime importance defence, security, (road, air and maritime) safety, emergency, law enforcement, and scientific-oriented activities. As a result, an efficient and coherent use of spectrum in all these sectors can, by stimulating growth and competitiveness, contribute towards realizing priorities and establishing commonly acceptable policies, that lead to the development of wireless communications technologies has enabled new and effective forms of voice and data communication building a 'fully inclusive' information society, based on the extensive use of ICT (Information and Communication Technology). In view of the requirement of the information society for instantaneous access to, and dissemination of, information, irrespective of time and/or location, radio spectrum is a factor of unlimited importance for the further advance of the Korea( Rep. of) economy. However, access to this spectrum resources can be artificially restrained when spectrum management policies fail to keep pace with advances in spectrum technologies. Therefore, this paper research a comparative law study on the spectrum management system of the radio spectrum policy's advanced countries in the legal viewpoint.
In this paper, the issues of the spectrum management system can be mentioned as below :
At first, spectrum refarming (i.e. spectrum redeployment) is a spectrum management tool, which can be used to satisfy new market demands, increase spectrum efficiency or to respond to changes in international frequency allocations. This work investigates differences, especially about the refarming plan of the low frequency bands, between some overseas policies and Korea(Rep. of). Studying on the refarming plan of the low frequency bands, we lay out the policy improvement program of spectrum refarming for raising efficience of the radio wave resources. The U.S. have secured 108MHz bandwidth in the 700MHz band by a firm digital TV transition date (June 12, 2009). According to digital TV transition schedule of the 60MHz available in the upper band (746-806MHz), FCC allocated 24MHz for public safety and ordered the aution of 32MHz for commercial use to begin in January 2008, so the remaining 4MHz are guard bands. On 2007, Ofcom of the U.K. published its 'Digital Dividend Review', which sets out proposals for consultation for the most effective use of the spectrum that will be released by digital switchover is in the UHF band in the frequencies 470-862MHz. 112MHz of spectrum that will become available as a result of digital switchover. These channels are numbered 31-35, 37, 39-40 and 63-68. Channel 36 is currently used for airport radar and Channel 69 for wireless microphones. Both channels have the potential to be cleared, and together make up 16MHz of spectrum.
Secondly, An aspect of spectrum reform receiving increasing attention is the introduction of secondary markets for spectrum in order to enable more flexibility to reassign unused and underused spectrum to users that will use it more efficiently. This paper proposes to focus on the policy issues relating to the development of well-functioning secondary markets for spectrum. Despite the compelling potential benefits, the secondary market for spectrum remains underdeveloped in countries that have introduced it. This section draws on various government documents and government commissioned reports and experience in countries that have introduced spectrum trading to identify a range of regulatory policy issues relating to spectrum trading. Despite the persuasive rationale for spectrum trading, countries have been slow to introduce it. This is in part because a number of significant concerns remain in regard to spectrum trading and liberalization. The presence of such concerns makes it understandable if countries decide to introduce spectrum trading through a phased stage-by-stage approach (as the U.K. has done). And it underlines the continuing need for a wide range of regulatory tasks to establish and sustain well functioning secondary markets for spectrum.
Thirdly, the rapid growth in demand for radio frequency spectrum causes increase radio spectrum management costs, and funds for considerable and ceaseless R&D investment are needed to promote innovation wireless communications and broadcasting areas. In accordance with the 1st clause, the 67th article, Radio Waves Act, the Korea Communications Commission (hereinafter referred to as “KCC”) can impose and collect spectrum fee on using radio stations for appropriating the spectrum management costs and for promoting the fields of involving in radio spectrum. Spectrum fee must impose and collect under user pays principle. I ultimately expect the scope of using spectrum fee to be enacted more clearly and precisely.
Fourthly, what is spectrum liberalization? Most spectrum licences include restrictions on the services and technology that can be deployed over the specified band of frequencies. Liberalization reduces or removes these limitations and will allow licence holders greater flexibility in the way they use their licences. Ofcom expects that spectrum liberalization and trading will make it easier for entrepreneurs and innovators to enter the market, deploy new technologies and applications, and compete with existing players; they will make it easier for spectrum to migrate from relatively low value uses to higher value ones. Although spectrum trading and liberalisation are distinct developments, they are complementary. A recent report for the European Commission estimated the benefits of spectrum trading with liberalization to be some ??9bn per year across the EU, predominantly arising from the earlier adoption of new technologies and applications that trading and liberalization would allow. The benefits of spectrum trading alone, without liberalization, were estimated to be about one tenth of this. So this paper analyzed Korea existing spectrum policy and compared it with trends of spectrum policy of leading country like U.S.A. and U.K. etc. As a result, we proposed to introduce interference management which allow interference to be controlled by marked like marketable pollition permits. I expect that if we set interference management for liberalization, technical and service conditions related to spectrum licences will be mitigated by managing interference directly.
Fifthly, new technologies such as SDR, UWB, and CR are expected to alleviate the scarcity of radio spectrum to a large extent. For successful introduction of the new technologies, we need to design the policies which promote efficient sharing of the radio frequencies currently occupied by licensees in addition to overcoming technological hurdles. This paper draws implications from the review of the past examples of spectrum sharing. It also argues that two alternative mechanisms free contract and regulatory requirement may result in insufficient spectrum sharing unless the service provided by incumbent licensee and the new service are complementary each other. The ‘commons’ approach. By contrast, with the exclusive rights approach, a licence-exempt ‘commons’ approach allows access to spectrum by all users (open access spectrum) or to a group of users who hold the rights to that spectrum in common (spectrum commons). However, the commons regime recently proposed by many researchers to implement spectrum sharing has its own shortcomings that it does not have a proven efficient mechanism to control access and congestion. We are expecting concurrent future research on efficient mechanisms to control congestion under commons regime or to provide incentives for incumbent licensees to allow socially efficient level of spectrum sharing.
Sixthly, auctions are popular mechanism for the exchange of goods and services in the marketplace. Recently, U.S., U.K., and EU are seeking efficient use of scarce spectrum resources under marked-based spectrum management policy. Spectrum auction, trading and administrative incentive pricing (AIP) are regarded as major instruments for recent spectrum management policy. And usage liberalization and appropriate set up of spectrum usage rights (SURs) are preerquisites for the introduction of spectrum trading. Spectrum auction is needed for the efficient spectrum allocation. Since 1994, the Federal Communications Commission (FCC) has conducted auctions of licenses for electromagnetic spectrum. These auctions are open to any eligible company or individual that submits an application and upfront payment, and is found to be a qualified bidder by the Commission. FCC auctions are conducted electronically and are accessible over the Internet. Thus, qualified bidders can place bids from the comfort of their home or office. Further, anyone with access to a computer with a web browser can follow the progress of an auction and view the results of each round. From 2000-07-31 to 2000-08-18, the German government conducted an aution for 12 frequency blocks for the new UMTS mobile telephony standard. The total of the bids exceeded expectations by reaching the staggering amount of DEM 98.8 billions (EUR 50.8 billions).
Finally, the International Telecommunication Union (ITU) is a forward-looking, dynamic organization that has been in the business of helping the world communicate for over 140 years. Also, ITU is the leading United Nations agency for information and communication technologies. ITU's role in helping the world communicate spans 3 core sectors: radiocommunication, standardization and development. Especially, managing the international radio-frequency spectrum and satellite orbit resources is at the heart of the work of the ITU Radiocommunication Sector (ITU-R). The ITU-R World Radiocommunication Conference (WRC), which convenes every three to four years, is at the core of the international spectrum management process and constitutes the starting point for national practices. WRC reviews and revises the Radio Regulations, an international treaty establishing the framework for the utilization of radio frequencies and satellite orbits among ITU member countries, and considers any question of a worldwide character within its competence and related to its agenda. However, the government of the Republic of Korea has faced a lot of challenges such as the lack of experts who keep consecutive participation in the conference, insufficient study materials, limited opinion channels, loosened cooperation in regional organization and delayed implementation of WRC results. But, in this paper, it foundationally researched ITU, ITU's legislation and WRC. Especially, we must be continuously carrying out research on spectrum management of the ITU.
To ensure that spectrum management policies of KCC are capable of harnessing the promise of beneficial, new technologies, first of all, the most important strategy is that the KCC has the spectrum management policies for the spread of the Radio Waves Mind. These include spectrum usage liberalization, spectrum common model, market-based spectrum auctions, spectrum trading, and so on. The KCC is an independent regulatory agency established by the Act on the Establishment and Operation of Broadcasting and Communications Commission. Its mission includes regulating communications by radio frequency spectrum. On the other hand, Its the most important mission, for the spectrum promotion, is the spread of the Radio Waves Mind. What is the best way to do it? It is the best way that restrictions on access to spectrum resources is eased. Finally, this work might be expected to be used as critical research material to form the effective as well as efficient spectrum management and policy improvement plans.
