Airport Comm. Cordless Phone (CT-1) Wireless Microphone Cordless Phone 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 Hyungsoo Lee, Cheolhyo Lee, Jaeyoung Kim, ETRI

  4. 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.

  6. Korea 915MHz PHY 908.5~914MHz 2MHz 1.2MHz 906 908 910 912 914 916 918 920 922 924 902MHz CH1 CH10 928MHz Comparison between Frequency Utilization of United States and RFID Frequency of Korea • RFID band in Korea allocate two channels in frequency band of United States Hyungsoo Lee, Cheolhyo Lee, Jaeyoung Kim, ETRI

  7. 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) Hyungsoo Lee, Cheolhyo Lee, Jaeyoung Kim, ETRI
