"ITU": A specialized agency of the United Nations that is responsible for issues that concern information and communication technologies.

Some countries drive on the right and some countries drive on the left. However there is no country that allows drivers to drive on both right and left at will. It is necessary to predetermine either right-hand or left-hand traffic. Otherwise, driving on the roads would be synonymous with having traffic accidents.

For a similar reasons strict rules are set for the use of radio waves with regards to frequencies used, output and so forth, and it's the ITU - International Telecommunication Union - who establishes these standards with which each country must comply.

The ITU is a UN organization headquartered in Geneva, Switzerland. Issues related to wireless communications are discussed at the ITU-R which is comprised of several study groups, and its decisions are notified to member countries as the "ITU Recommendations".


Participate in the UN conference as a member of the Japanese delegation and "ad hoc government official"

KKE's Yukiko Kishiki (Social Infrastructure Systems Department) visits Geneva almost every year as a member of the Japanese delegation which participate in the ITU-R.

"I'm an ad hoc government official. So far I participated three times, so I have three letters of appointment from the Minister for Internal Affairs and Communications. "

Kishiki explains her work as a delegate as follows:

"The study group I work with establishes the standards about the basic data and calculation formula for radio wave propagation. The "Recommendation" issued by this study group is the standard on radio wave use. It is considered as a bench mark of the radio wave use by the policy makers and radio engineers of each country.

The atmosphere of the meeting is academic and amicable. It is not a place where countries fight for their national interests. I once served as a chairperson at the meeting on "the standard calculation formula that describes the radio wave leakage". Although it was a niche subject, we were making decisions on a world standard, so I felt a heavy burden of responsibility. However, I think I could control the discussion without any problems. "


Environmental improvements for a better future

In addition to the government officials, the Japanese delegation includes researchers from independent administration corporations, university professors and representatives from private telecommunication companies. KKE doesn't fall into any of those types. We became a team member because the Japanese Ministry of Internal Affairs and Communication asked us to participate in the delegation because of our expert knowledge and know-how in this field.

"Since I don't belong to any particular telecommunication company, I have a merit of being able to present opinions from a neutral standpoint. At the same time, my opinion has to be based on a high level of scholarship worthy of the name of Japanese delegate, so my feeling of tension continues from the time I prepare for the conference through my stay in Geneva. "

Kishiki works on the extremely high frequency band such as the millimeter wave (30GHz~) and submillimeter wave(300GHz~). Also referred to as the terahertz wave and sharing boundary with the infrared ray, they belong to the "last radio wave resource" territory.

"Currently, the application of this technology is expanding to the areas other than communications, like the car-collision preventing vehicle proximity radar and concealed weapon/explosives detection system. However, as we observe the network congestion caused by the increasing use of cell phones and Wi-Fi, it is inevitable that this extremely high frequency band would be used for communication. In order to avoid interference and make it available for more people, we have to start working for solutions now."
