Additionally, MIC informs that UWB devices should have the following:

  • Average antenna power of -41.3 dBm/MHz or less

  • Peak antenna power of 0 dBm/50 MHz or less

  • Tolerance of occupied frequency bandwidth should be 1.75 GHz

  • Frequency bandwidth for radiant power 10 dB lower than maximum radiant power: 450 MHz or higher

  • The design of housing should prevent easy opening

The document revised technical conditions requirements to the mmWave radars operating on 60 GHz band.

  • Frequency allocation 57 GHz ~ 64 GHz

  • Antenna power should be 12 dBm or less

  • Equivalent isotropic radiated power should be 17 dBm or less

  • Pulse amplitude modulation type
