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 802.15.4 because it is ISM band

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

908.5~914MHz band assignment of Korea Plan to assign 908.5~914MHz 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.

Utilization Methods of 908.5~914MHz

Proposal of adapting North America specifications to IEEE 802.15.4 in Korea Assignment of two channels

Another solution Proposal of Europe specifications

which enable to increase channels- Case 1 : 0.6MHz band/channel- Case 2 : 1MHz band/channel- Assignment of Maximum 8 channels

Summary

Possibility to share frequency : Two scenarios Sharing with RFID band Sharing with Wireless Microphone band

Review of applying appropriate specifications to IEEE 802.15.4 With North America specifications With Europe specifications

Research for interference analysis of sharing frequency band by Korean Home Network Study Group started from May 2004

Note : ETRI would like to acquire the document related with reviewing interference and sharing frequency in other countries
