FACS (Flexible Access Common Spectrum) 57~64 GHz, Open to anyone meeting interference criteria below introduction of technology neutrality and less regulation to promote further growth in the domestic radiocommunication market

FACS (Flexible Access Common Spectrum) 57~64 GHz, Open to anyone meeting interference criteria below introduction of technology neutrality and less regulation to promote further growth in the domestic radiocommunication market

Interference criteria of a device using FACS

= Power x BWratio x (DFratio or Tratio) x BF

Power: Transmit Power

DFratio: Duty Factorstandard / Duty Factor

Tratio: Channel Occupied Timestandard /Occupied Time

BF: Balancing Factor

Exchange of information on R&D and standardization on CR technology is desirable. In particular, what kind of services are considered to use CR technology in what frequency band in your country?

Since CR is considered to be useful technology to provide flexibility

and versatility of resources and radio systems
