The comparable technology in the context of GSM is [[GSM-1800]], also known as "[[Digital Cellular System]]" (DCS).<ref>{{cite conference |last1=Ramsdale |first1=P.A. |last2=Hadden |first2=A.D. |last3=Gaskell |first3=P.S. |title=DCS1800-the standard for PCN | conference=1991 Sixth International Conference on Mobile Radio and Personal Communications |date=December 1991 |pages=175–181 |url=https://ieeexplore.ieee.org/document/140234}}</ref> GSM-1800 launched in Hong Kong in 1997. It can form [[dual band]] service with GSM at 900MHz. This frequency was [[UMTS frequency bands|inherited into UMTS]], [[LTE frequency bands|LTE]], and [[5G NR frequency bands|5G NR]].

Korea, which has never used GSM, runs CDMA on 1800 MHz. See [[CDMA frequency bands]].
