  1. Discussion of Pending WLAN Spectrumin Korea Bruce Kraemer, Intersil Bruce Kraemer, Intersil

  2. Executive summary • Korea is considering allowing WLANs to use spectrum in the 2.3 GHz band in addition to 2.4 GHz. • Is this relevant to IEEE 802.11 or 802.18? • Need more factual information • Spectrum/Channel assignment? • Radio etiquette? • Single use or shared? • Licensed or unlicensed? Bruce Kraemer, Intersil

  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 2004. KT and Hanaro have used the 2.3 giga-hertz spectrum to develop their wireless and broadband Internet services. kdh@koreatimes.co.kr 입력시간 2002/10/31 17:51 Bruce Kraemer, Intersil

  4. Situation (as currently understood) • The 2.4 GHz is assigned in the following way: • Base stations are Licensed, mobiles are License-Exempt. • 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. • Mobiles will be License-exempt. Bruce Kraemer, Intersil

  6. Korean regulators on telecommunications • Ministry of Information and Communications (MIC) • www.mic.go.kr • Korean Communications Commission (KCC) • Under auspices of MI • www.kcc.go.kr • Telecommunications Technology Association • The scope of TTA's activities include the fields of telecommunications, information technology, Radio Communication & broadcasting, establishing approximately 2,000 TTA Standards until now. • Which are relevant to the 2.3 GHz allocation issue?

  8. Call for contributions • This version of the presentation is based upon pieces of information collected from news articles & websites • We need a more thorough understanding of MIC plans and options • Need to determine IEEE 802.11/802.18 activities based on above Bruce Kraemer, Intersil

  9. Sample of Korean Members • Dae Sung New Tech - Yong Man Jang • ETRI – You Sung Kang • Samsung Advanced Inst of Tech • Young Guen Hyun, Dongjun Lee, Kisoo Chang • Samsung • Jong Ae Park, Oh Sang Kwon Bruce Kraemer, Intersil

  10. Questions • Should consider 802.11 in the band? • Is there enough usable spectrum? • Which waveforms, data rates to consider • 802.11b, 802.11g • What are the roles of 802.11, 802.18, 802.16, 802.20 (others?), ? • Who within 802.11 can help? • Which ministry group(s) in Korea could be approached for information or to express opinions? Bruce Kraemer, Intersil

  11. Proposed Next steps • Use WNG session time in Dallas to collect further insights • Present situation to 802.18 for review • Between meetings, use technical reflector for comments • If appropriate, invite Representative of MIC to May meeting in Singapore • In May WNG meeting: revise status, discuss and set plans Bruce Kraemer, Intersil
