Federal Communications Commissions (FCC) has adopted a new rule that can provide a 1,200 MHz unlicensed spectrum to maximize the public benefits in the 5.925 ~ 7.125 GHz(6 GHz) band by expanding unlicensed broadband into the 6 GHz band while also ensuring that licensed services that operate in the band continue to thrive. In Korea, the M/W band of 6 GHz has been reallocated to introduce unlicensed services in the 6 GHz band. Considering the national interests, the entire 1,200 MHz will be supplied for the indoor uses, but only the 500 MHz of the lower bandwidth (5925 ~ 6425 MHz) will for the outdoor uses under the limited power to protect the incumbent services. The introduction of unlicensed devices is being actively promoted through the reallocation of the 6 GHz M/W band, but since it is desperately necessary to prepare technical requirements to operate them in Korea. In this paper, the US 6 GHz unlicensed rules has been analyzed, these results will be utilized for establishing Korean technical standards with the unlicensed spectrum expansion.
