  16. Chapter 3 -Technical Requirements- Transmitting equipment - Antenna power (Bulletin, 1989, No. 42) The antenna power (the power that is supplied from the transmitting equipment to the feed wire of the antenna system) shall be 10 mW or less. - Permissible deviation in antenna power(Facilities, Article 14) The permissible antenna power deviation, which is the maximum deviation from the specified or standard antenna power that can be permitted, is 50% higher or 70% lower. - Permissible deviation in frequency(Facilities, Article 5) The permissible frequency deviation (the maximum permissible deviation from the frequency that is assigned to the center frequency of the occupied frequency band) shall be +/-50010-6. - Permitted values of the occupied frequency bandwidth (Bulletin, 1989, No. 51) The permitted value of the occupied frequency bandwidth shall be 2.5 GHz. - Permitted value of the spurious radiation strength (Facilities, Article 7) The permitted value for the strength of spurious radiation, in the case of modulation by the usual modulation schemes, shall be 100 W or more as measured by the mean power. Concerning equipment that possesses the function of transmitting unmodulated carrier waves, evaluation shall be possible by measurement of the unmodulated carrier waves. Hiroyo Ogawa, CRL

  17. Chapter 3 -Technical Requirements- Receiving equipment - Limit of secondary emissions, etc. (Facilities, Article 24) Concerning the limit at which secondarily-emitted radio waves do not interfere with the functioning of other radio equipment, when the limit is measured with a dummy antenna circuit that has electrical constants that are equal to those of the receiving antenna, the power of that circuit shall be 100 mW or less. Antennas - Antenna gain (Facilities, Article 49, item 14) The transmitting aerial antenna shall have an absolute gain of 47 dB or less. Other - Enclosure (Facilities, Article 49, item 14) The transmitter shall be accommodated within a single enclosure that cannot be opened easily. However, this restriction shall not apply to the power supply equipment, aerial antenna, power cord and accessory devices. Hiroyo Ogawa, CRL

  18. Chapter 4 -Measurement Methods- The measurement methods shall be in accordance with “Characteristics Testing Methods for Equipment Technical Standard Conformance Certification of Radio Equipment,” (established by the Telecommunications Engineering Center). However, concerning items other than those specified here, the generally-used methods shall be applied.

  21. Preface of ARIB Standard • The Association of Radio Industries and Businesses, whose participants include radio equipment manufacturers, telecommunication businesses, broadcasting companies and users, establishes as ‘standards’ the standard specifications and other such basic conditions concerning the radio equipment that are related to various types of systems that employ radio waves. • Standards include national technical standards that are established for the purposes of efficient frequency utilization and prevention of interference between users as well as private-sphere standard specifications that are established for purposes of ensuring the overall product quality, compatibility, etc. of radio equipment, and the convenience of radio equipment manufacturers and users. • The standards described here concern “millimeter wave video transmission equipment for specified low-power radio stations.” In order to ensure fairness and transparency at the stage of establishment, this standard was established through the consensus of the participants of this standards conference. Participants included radio equipment manufacturers, telecommunication businesses, broadcasting companies, testing organizations, users and other such interested parties, who were accepted without discrimination. • It is hoped that this standard will find active use among radio equipment manufacturers, testing organizations, users and other such parties.
