Sept. 2004 doc. : IEEE 15 -04 -0482 -02 -004 b Analysis of Available Frequency Band Ø Possible analysis scenarios § Scenario 1 : Reallocation of unused CT-2 frequency band - Total band : 908. 5~914 MHz • CT-21) band : 910~914 MHz • Use adjacent guard band : 908. 5~910 MHz § Scenario 2 : Frequency sharing of Low Power Device - Sharing with Wireless Microphone band : • 928~930 MHz and 950~952 MHz Ø 908. 5~914 MHz band assignment of Korea § Plan to assign 908. 5~914 MHz to RFID in order 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.
