The MIC working group for 6/7 GHz microwave equipment concluded that the regulation for antennas would be relaxed and fulfil the ETSI standard EN 302 217-4 for Class 3 and 4 antennas in Japan. This is very important for the users of microwave in 6/7 GHz bands. However, the regulation for interference is very complexed and the requirement for IRF (Interference Reduction Factor) will not be relaxed and a consequence of this there are no microwave short haul products based on ETSI standard available for Japan.EBC notes that MIC is revising EMF evaluation methodologies of mobile radio base stations according to the international standards.

Recommendations

  • Japan should also make a study to investigate the relaxation of the requirement to accept Class 3 and 4 antennas defined in ETSI EN 302 217-4 for all licensed bands, such as 11/15/18 GHz.
  • MIC should start a new study as soon as possible to update IRF for the other systems (broadcasting systems) so to enable the introduction of global standard equipment that complies with ETSI/ANSI specifications.
  • MIC should introduce BS EMF evaluation methodologies according to EN IEC 62232.
