This ARIB Standard ARIB STD-T97 specifies on "radio equipment for a radio station in which a transmitting burst length is a multiple of the natural number for 911.46 microseconds, or a multiple of the natural number for 911.46 microseconds added with 1,070 microseconds" which was formerly specified as "radio equipment for a radio station of Orthogonal Frequency Division Multiple Access broadband mobile radio access system" which was defined in the Article 49-28 of the Ordinance Regulating Radio Equipment(ORE), and also on "radio equipment for a radio station of Time Division, Frequency Division Multi Access broadband mobile radio access system" which was formerly defined in the Article 49-30 of ORE.

These articles of ORE were however deleted by the subsequent amendment of MIC Ordinance, and this ARIB Standard ARIB STD-T97 is suppressed.

This system is one of the broadband mobile radio access systems using 2.5GHz band and is a wireless broadband system that can respond to the mobility from standstill to 250km per an hour. It has higher transmission rate, improved technology in efficient use of frequency and a QoS technology that surpass those of the current third-generation mobile phone system and is a wireless system for broadband data communication services for public use on the premise that it is connected to all IP-based network.

This ARIB Standards is intended to achieve a system called IEEE 802.20 in Japan.

Note that this standard is prepared only in English.
