Sept. 2004 doc. : IEEE 802. 15 -04 -0458 -00 -004 b Usable or Sharable Frequency Band Analysis • Case 1 : Reallocation of unused CT-2 frequency band – Total sharable band : 908. 5~914 MHz • CT-21) band : 910~914 MHz • Use Guard band : 908. 5~910 MHz • Case 2 : Frequency sharing of Low Power Device – Sharing with Wireless Microphone band : • 928~930 MHz and 950~952 MHz • Korean Government will assign 908. 5~914 MHz 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.
