Utilization of 860~960MHz Band in Korea
• No ISM band between 860~960MHz in Korea• 868~868.6MHz : Airport Communication Service• 902~928MHz : CT-1, CT-2, Safety Service, Pager• Now CT-2 service returned frequency license

Usable or Sharable Frequency Band Analysis
• Case 1 : Reallocation of unused CT-2 frequency band – Total sharable band : 908.5~914MHz
• CT-21) band : 910~914MHz• Use Guard band : 908.5~910MHz
• Case 2 : Frequency sharing of Low Power Device– Sharing with Wireless Microphone band :
• 928~930MHz and 950~952MHz
• Korean Government will assign 908.5~914MHz frequency band to motivate RFID industries in Oct 2004
1) CT-2 : Cordless Telephone (second generation). A type of "public" cordless telephone that is connected by TDMA radio links to nearby, microcell base stations. CT-2 is most often used as a wireless payphone. Receiving calls is not possible.

Summary
• Examining two frequency sharing cases in Korea– Sharing with RFID band– Sharing with Wireless Microphone band
• Reviewing appropriate method– With United States band (902~928MHz) – With European band (868~868.6MHz)
