Publication of"Guidance for the safe and secure radio wave use in medical institutions"
Recently in medical institutions, utilization of devices using radio waves, such as wireless
LAN routers, mobile phones, and so on, is advancing. In addition, people who use hospitals,
such as patients or visitors, also have growing demand for using cellular phones and thelike in hospitals.
On the other hand, in the case of absence from proper radio wave management, there is apossibility that troubles affecting medical devices will occur.
Therefore, in September 2015, "Telecommunications Promotion Committee in medical
institutions" was set up in the Electromagnetic Compatibility Conference Japan (EMCC),
which secretariat is served by ARIB.
In the Committee, in order to promote proper use of radio waves in the medical
institutions, academic experts, related organizations, medical equipment manufacturers,2

medical equipment dealers, construction companies, telecom operators, related ministries("Ministry of Internal Affairs and communications (MIC)", "Ministry of health, Labour andwelfare") etc. had participated.
On the basis of the study results in the Committee, "Guidance for the safe and secureradio wave use in medical institutions" and "2015 annual report of Telecommunications
Promotion Committee in medical institutions" had been compiled and published on 4 April
2016.

We mainly made a correspondence to the ITU-R SG6 meeting as follows.
For sound metadata and sound file format, the new draft recommendation which
defines the channel of the label and the arrangement to be used in the ADM (Acoustic
Definition Model) was published, so we proposed to achieve the match of the contentsof the current recommendation and the content of report.
In the channel allocation to be used in the transmission system for sound program
contribution, recommendation BR.1384 was abolished, provisions of less than 8ch was
integrated in the recommendations BS.1738, provisions of more than 12ch was
proposed as a new recommendation.
In case of the broadcast station transmits a broadcast program, in the sound delivery
and playback adapted to the viewing environment, regardless of the radio wave
broadcasting or network distribution, we proposed the level of -24LKFS (Loudness
K-weighted relative to nominal Full Scale) for target loudness.
In the subjective quality assessment method of channel-based advanced sound system,
we proposed a revision of Recommendation BS.2051 in order to unify the positive
angle of the channel label to the right.
Regarding the level of conversion from the stereo program to monaural program, we28

are discussing draft revision of TR-B30 (The Technology Guideline of Production for
Surround Broadcast Program).
