doc.: IEEE b Submission Sept Hyungsoo Lee, Cheolhyo Lee, Jaeyoung Kim, ETRISlide 3 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 TRS PAGERPAGER Broadcasting Relay Mobile Phone Airport Comm. Wireless Data Comm. Cordless Phone (CT-1) Cordless Phone Wireless Microphone Wireless Data Comm. 940 CT Safety Comm. 902

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.
