CDMA BC4 (Korean PCS)
CDMA BC4, also known as the Korean PCS frequency band, operates within the 1.8 GHz range. Specifically, the uplink frequencies range from 1750 MHz to 1780 MHz, and the downlink frequencies range from 1840 MHz to 1870 MHz. This band is used for both CDMA2000 and LTE services in Korea. It is notable for being a de facto standard in Eurasia and Africa and is used by major Korean telecommunications companies such as SK Telecom and LG U+ for their 2G/3G CDMA and 4G LTE services.
