doc.: IEEE /186r0 Submission March 2003 Bruce Kraemer, IntersilSlide 2 Executive summary Korea is considering allowing WLANs to use spectrum in the 2.3 GHz band in addition to 2.4 GHz. Need to discuss if is this relevant to IEEE or ? –Channel assignment? (802.11) –Radio etiquette? (802.11) –Wave form specific – single use or shared? (802.18) –Licensed or unlicensed? (802.18)

doc.: IEEE /186r0 Submission March 2003 Bruce Kraemer, IntersilSlide 3 Basis of Discussion – Report in Korea Herald Oct 30,’02 Korea to Reallocate 2.3 GHz Spectrum for Wireless Internet By Kim Deok-hyun Staff Reporter The Ministry of Information and Communication (MIC) yesterday it will reallocate part of the spectrum currently used by wireless local loop (WLL) for high-speed mobile Internet users. In a statement, the MIC said it decided to reallocate part of the spectrum, which was used by fixed-line broadband Internet companies such as KT and Hanaro Telecom, in preparation for the coming wireless Internet era. Under the decision, the MIC is to ask major carriers to gradually give up their spectrum rights, said Oh Seung-kon, the ministry official said. With the extra bandwidth, wireless Internet service providers will be better able to allow the transmission of video and other new wireless content, it said. The MIC said there would be no preferential treatment given to KT and Hanaro in the reallocation of the spectrum in KT and Hanaro have used the 2.3 giga-hertz spectrum to develop their wireless and broadband Internet services. 입력시간 2002/10/31 17:51

The Korean government is supporting the 5 GHz allocation of agenda item 1.5 of WRC 03. Korea is considering re-allocating spectrum in the 2.3 GHz band from fixed outdoor to mobile outdoor applications by the end of 2003 –Spectrum considered: ? To ? –WLL (fixed) currently is the assigned application –WLAN (mobile) being considered as a new application –Power level likely 200 mW (23dBm) –Allocation may be based on competitive runoff, winner take all E.g. MBWA, WLAN, other Base stations will be licensed to a single business unit to be formed by the 3 large telecom providers in Korea, including additional providers. Mobiles will be License-exempt.
