Recently, many of the mobile network operators or telcos are introducing the LTE service in order to effectively cope with an explosive increasing mobile traffics due to an expansion of the use of smart phones. The 1.8㎓, 2.6㎓, and 800㎒ band classes are most widely used for LTE. In particular, the 1.8㎓ band class is the most useful one in terms of the re-usability of the existing (2G) network, global harmonization, bandwidth, eco-system of equipments and devices, and so on. In recent years,

... countries in the world have allocated the 1.8㎓ band spectrum in a wide bandwidth unit suitable for the upcoming LTE-Advanced service. This paper surveyed the 1.8㎓ band spectrum allocation policies of the 12 OECD countries, including Republic of Korea. From the survey, we have found that they rebuilt or refarmed the existing holders' bands, recovered the public (i.e., military)-use bands, and allocated the bands in a wide bandwidth and in an equal or similar size.
