Sept. 2004
Utilization of 860~960 MHz Band in Korea
No ISM band between 860~960 MHz in Korea
868~868.6MHz : Airport Communication Service
902~928MHz : CT-1, CT-2, Safety Service, Pager
CT-2 service : returned frequency license
No problem using 2.4 GHz for IEEE because it is ISM band

4. Analysis of Available Frequency Band
Sept. 2004
Analysis of Available Frequency Band
Possible analysis scenarios
Scenario 1 : Reallocation of unused CT-2 frequency band
Total band : 908.5~914MHz
CT-21) band : 910~914MHz
Use adjacent guard band : 908.5~910MHz
Scenario 2 : Frequency sharing of Low Power Device
Sharing with Wireless Microphone band :
928~930MHz and 950~952MHz
Korean Government
Plan to assign 908.5~914MHz frequency band to motivate RFID industries at the end of 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.

7. Summary Possibility to share frequency : Two scenarios
Sept. 2004
Summary
Possibility to share frequency : Two scenarios
Sharing with RFID band
Sharing with Wireless Microphone band
Review of applying appropriate specifications to IEEE
With United States specifications
With European specifications
Research for interference analysis of sharing frequency band by Korean Home Network Study Group started from May 2004
Note : ETRI need cooperation to acquire the document related with reviewing interference and sharing frequency in other countries
