HOME > RF-ID & Extremely weak power equipment

Radio Frequency Semi-anechoic Chamber	Open Test Site	Exp.:Radiation Pattern Measurement	Test Room

For installation of equipment using high frequencies (RF-ID: Radio Frequency Identification System of 13.56 MHz, as a typical example) prescribed in Article 100 of the Radio Law, the application for construction permit should be submitted to the Minister of Internal Affairs and Communications to receive government permission.
If you have received a type approval from the Minister of MIC in advance, the installation can be carried out without receiving a construction permit. To the application for receiving type approval, test data for the predetermined test items should be attached. We are engaged in representative service for performance evaluation measurement of RF-ID and for application of type approval of RF-ID to the Minister of MIC.

Extremely weak power equipment
One of services is to certify that radio stations whose transmission power are extremely weak are not required licenses by measuring the field intensities and confirming that the measured results satisfy the standard stipulated in the Radio Law. The condition of radio stations which are not required radio licenses is shown in the attached table. Various types of equipment such as low output cordless telephones, wireless microphones and emergency alarm transmitters on the market today are subject to this service. In addition to performance certification of such extremely weak power equipment, RFT certifies the low power radio equipment whose power is greater than that of extremely weak power equipment.
