based on Telecommunications Business Act2

Interpretation“The terminal equipment that transmits radio waves in the terminal facility” is equipment for approval in accordancewith Article 9 of the “Ordinance Concerning Terminal Facilities, etc.”
Type of radio equipment to be used with typical wireless-communications protocol are shown in the Attached Table.
The Specific scopes of the application object are shown in the Attached Tables (Case 1, 2 & 3).
The most interfaces for terminal equipment connecting to the existing approved terminal are 10/100BASE interface; therefore,
it shall be basically approved as “D approval” since the interfaces are considered as the demarcation point.
However, if the existing approved terminal is specified as “A” or “C” approval, then the terminal also shall be approved as “A” or “C”.
Case 1: The terminal equipment that transmits radio waves listed in the Attached Table in the terminal
facility, shall be treated as “Case 1” and approved as usual.
Case 2: Under typical wireless communication protocol, the terminal equipment shall be approved as themaster equipment which connects to the existing approved slave equipment.
Case 3: Under typical wireless communication protocol, the terminal equipment shall be approved as theslave equipment which connects to the existing approved master equipment.
In case of a Public Wireless LAN type of connection configuration, it could be considered as an aspect of the mobile radio terminal facility
under the Ministry of Posts and Telecommunications, Notification No. 72, Article 2 of 1994; however there is no registered
telecommunications
carrier concerned at this point.
Naturally, under this connection configuration, two beneficiaries arise (public wireless LAN operator and its user) and the terminal
equipment is considered as a part of network service business. However, under the technical aspect, it is also considered as the connection
required by Article 9 of “Ordinance Concerning Terminal Facilities, etc.”, therefore this terminal equipment shall be approved by itself.
・Others
1. Since the communication of general wireless mouse, wireless keyboard, etc., are not the telecommunications carrier's services(voice service and data communications service) based on the Telecommunications Business Act, they are not objects of approval.
2. A wireless headset (handset) is object of approval for the above-mentioned voice service.
Also, Chapter 3 (Safety, etc.) Article 7 (Occurrence prevention of an excessive acoustic shock) of “Ordinance Concerning Terminal
Facilities, etc.” will apply.

Reference : Ordinance Concerning Terminal Facilities, etc. (Article 9)
Article 9 Terminal equipment that uses radio waves between sections includedin the terminal facility must comply with the requirements indicated below.
1An Identification Code (code to identify radio facilities used as terminal facilities andreferenced during setting of the communication channel) that conforms to therequirements published separately by the Minister of MIC must be provided.

2This equipment must determine whether the frequency for utilizing electric waves isopen or not in accordance with the separately published notice from the Minister ofMIC, and must establish a communication channel only when that frequency is open.
This stipulation, does not apply to those cases specifically noted by the Minister ofMIC.

3 The radio facility must be stored in a single cabinet that can not be easily opened. This
stipulation, however, does not apply to cases specifically noted otherwise by theMinister of MIC.
*Related Notification: Identification codes and other conditions based on rules of Ordinance Concerning TerminalFacilities, etc. (Article 9 of Ordinance Concerning Terminal Facilities, etc.) :Ministry of Posts and Telecommunications,Notification No. 424 of 1994 (As amended last by Notification No. 537 of December 14, 2011)8
