On October 12, 2011, the Ministry of Internal Affairs and Communications (MIC) submitted an inquiry to the Radio Regulatory Council (Chairman: Hiroshi Harashima, emeritus professor at The University of Tokyo) concerning a ministerial ordinance plan for partial revision of Radio Law Enforcement Regulations (1950 Radio Regulatory Council Regulation No. 18) and regulations relating to the technical standards compliance verification, etc. in special wireless equipment (1981 Ministry of Posts and Telecommunications Order No. 37) in order to introduce an 80Ghz-band high speed wireless communication system, and on the same date a reply was received from the Council stating its approval of the original plan.
Opinions on the ministerial ordinance plan subject to this reply were sought from August 10 to September 8, 2011, but no opinions were submitted.
Please note that results from the appeal for opinions on expanded use of 5GHz-band wireless access systems will be announced separately.
1. Background to revisions
At present, wireless communication systems using microwaves/milli-waves are implementing and applying transmission speeds of above 100Mbps, although there has been almost no spread of systems that exceed these speeds. Accordingly, there is now demand for the implementation of high-capacity milli-wave communication enabling consecutive frequency allocation that is suitable for high capacity communication.
In contrast, optical cables are utilized at speeds of from several-hundred Mbps to 10Gbps, and there are expectations for the implementation of a wireless communication system for the transmission of high-definition images at speeds of 1Gbps or faster in non-compressed formats and with minimum latency, as well as hopes for the implementation of a system that will enable line construction with relative flexibility and ease in areas where it is difficult to lay optical cables, etc.
In light of these circumstances, in October 2010 the Information and Communications Council commenced deliberation on “technical standards for an 80Ghz-band high speed wireless communication system” and compiled a partial report in May 2011 towards a decision on the technical standards for this system, which it is assumed will use the 80Ghz frequency band that has yet to be fully utilized in Japan.
The Radio Equipment Regulations and technical standards compliance verification, etc. in special wireless equipment will be revised, and the “80GHz-band high speed wireless communication system” will be introduced, with the establishment of technical standards relating to the 80GHz-band high speed wireless communication system based on this partial report.
2. Outline of revisions
The following ministerial ordinances are revised due to the introduction of the 80GHz-band high speed wireless communication system.
・Ministerial ordinance plan for partial revision of Radio Equipment Regulations
・Ministerial ordinance plan for partial revision of technical standards compliance verification, etc. in special wireless equipment
3. Result of appeal for opinions
No opinions were submitted.
System maintenance will promptly be carried out based on the report from the Radio Regulatory Council, etc.
5. Related reports and announcements
・Appeal for Opinions on Revised Ministerial Ordinances, etc. concerning Introduction of 80GHz-Band High Speed Wireless Communication System and Expanded Use of 5GHz-Band Wireless Access System
