Press Release

April 27, 2012

Appeal for Opinions on Draft Ministerial Ordinances and Notices pertaining to Technical Requirements for Specified Radio Microphones, etc.

Institutional improvement for specified radio microphones aiming to a frequency change
  The Ministry of Internal Affairs and Communications (MIC) compiled a draft revision, etc. on Ministerial Ordinances related to the Radio Act for the switching over of frequencies of specified radio microphones, etc. From April 28 (Sat) to May 28 (Mon), 2012, the MIC will hold an appeal for opinions on said draft revision.

1.Background

  Specified radio microphones were institutionalized in 1989 as radio stations of analogue radio microphones of high-quality sound used in production of broadcasting programs, concerts, stages of theaters, event sites, etc. and have broadly been used in accordance with various needs.
  On the other hand, the Action Plan for Spectrum Reallocation formulated in September 2011 states that deliberations and works toward the switching over of frequencies shall be made by pushing forward technical deliberations on the switching over of frequencies considering an option over which the frequency will be switched as white space of a frequency range for terrestrial television broadcasting or the 1.2GHz band based on the basic guidelines for allocation of 700/900MHz-band frequencies in order to ensure frequencies for mobile radiocommunication in the 700HMz band.
  In view of these circumstances, the Mobile Communications System Subcommittee, Department on Information and Communications Technology, Information and Communications Council has deliberated on technical requirements for switching over, etc. of frequencies of specified radio microphones from January 2012 and a partial report was received from this Council on April 25, 2012 as a result of its deliberations.
  Related provisions necessary for the switching over, etc. of frequencies of specified radio microphones will be consolidated based on said partial report.
 

2.Outline of revision of each system

  (1) Land mobile stations of specified radio microphones
  Related Ministerial Ordinances, etc. will be revised to review frequencies used, modulated frequencies, acceptable value of intensity of spurious emission or unnecessary emission, available antenna power, etc., as there are needs for high-quality sound and it is necessary to strive to switch over frequencies based on the Action Plan for Spectrum Allocation.

(2) Land mobile stations of specified digital radio microphones
  Related Ministerial Ordinances, etc. will be revised to review frequencies used, acceptable value of intensity of spurious emission or unnecessary emission, etc., as it is necessary to strive to switch over frequencies based on the Action Plan for Spectrum Allocation.
 

3.Guidelines for appeal for opinions

  (1) Subjects of appeal for opinions
  - Draft Ministerial Ordinance for Partial Revision of the Ordinance Regulating Radio Equipment
  - Draft Ministerial Ordinance for Partial Revision of the Ordinance Concerning Technical Regulations Conformity Certification of Specified Radio Equipment
  - Draft Notice for Partial Revision of the Subject Stipulating Characteristics of Receiving Equipment Applied to Examinations of Applications for Radio Stations of Land Mobile Services, Radio Stations of Portable Mobile Services, Convenience Radio Stations and Premises Radio Stations (Notice of MPT No.395 of 1986)
  - Draft Notice for Partial Revision of the Subject Stipulating Equipment not Required to be Accommodated in One Case of Radio Equipment of Land Mobile Stations of Specified Radio Microphones (Notice of MPT No.315 of 2000)
  - Draft Notice for Partial Revision of the Subject Stipulating Equipment not Required to be Accommodated in One Case of Radio Equipment of Land Mobile Stations of Specified Digital Radio Microphones (Notice of MPT No.129 of 2009)
  - Draft Notice Stipulating Technical Requirements for Radio Equipment and its Transmitting Antennas to which the Provision of the Main Text of Item 8 based on the Provision of the Proviso of Article 49-16, Item 8 of the Ordinance Regulating Radio Equipment is not Applied
  - Draft Notice Stipulating Separately-stipulated Acceptable Value of Intensity of Spurious Emission or Unnecessary Emission of Transmitting Equipment of Land Mobile Stations of Specified Radio Microphones and Specified Digital Radio Microphones based on the Provision No.22 in Appended Table 3 of the Ordinance Regulating Radio Equipment

(2) Deadline for appeal for opinions
  At noon on May 28 (Mon), 2012 (submissions by mail must arrive by this date)
  The draft revision will be posted in the column of “public comments” on the e-government portal (e-Gov) (http://www.e-gov.go.jp) and also distributed at counters of contact.
 

4.Future plans

  The MIC will revise related Ministerial Ordinances, etc. based on the opinions submitted and the report from the Radio Regulatory Council in response to the inquiry to this Council.
