Outline of ARIB


Outline of ARIB

• EstablishmentEstablishment: merge of two Organisations in 1995:– Research & Development Center for Radio Systems (RCR)– Broadcasting Technology Association (BTA)

• ObjectiveObjective: promotion of pubic welfare by means of:– conducting investigation, R&D and consultation of utilisation of

radio waves– promoting realisation and dissemination of new radio systems

• Main ActivitiesMain Activities:– investigation and R&D on utilisation of radio waves– establishment of voluntary technical standards for radio systems– consultation, dissemination, collection and publication of

information on utilisation of radio waves– frequency change support for terrestrial digital TV broadcasting– frequency termination support for re-allotment of radio spectrum

Recent ARIB Activities for IMT-2000 Standards

• ARIB revises its standards on DS-CDMA and MC-CDMA, based on 3GPPs specifications, around every 3-4 months. – CDMA-DS: STD-T63, TR-T12– CDMA-MC:STD-T64, TR-T13

• Release 6 3GPP specifications (including HSDPA) and Release D Ver.1.0 of 3GPP2 specifications have already been transposed to ARIB standards.

• ARIB transposed 1xEV-DO specification in May 2002.


Activities for Future Mobile Communications Systems


Telecommunications Council Report on Future Mobile Communications Systems (1/3)

• Telecommunications Council issued a report on Future Mobile Communications Systems on 25th June 2001

• Image of Future Mobile Communications Systems– Users can access the Internet environment as they do in the office,

anywhere, anytime, without any restrictions.– Anything can be a mobile-communication terminal.– Terminals has outstanding number portability and users can

choose services and applications freely.– Highly advanced mobile EC (Electronic Commerce) will be

achieved.– There is the flexibility to introduce new technology to systems.

Ref.: http://www.arib.or.jp/IMT-2000/docs/Committee-Report.pdf



• Outline of Future Mobile Communications Systems– Capability to handle high speed multimedia– Service portability, seamlessness among networks– Ability to support highly advanced application such as mobile EC– The Systems are collective entities, consisting of Systems

beyond IMT-2000, Enhanced IMT-2000, High-speed wireless access, etc.

– The above systems interworks to provide seamless environment to user.

– Phased development (about 30 Mbps (down link) around 2005, 50-100 Mbps around 2010)

ITU-R Recommendation onSystems beyond IMT-2000

denotes interconnection between systems via networks or the like, which allows flexible use in any environments without making users aware of constituent systems.

Dark shading indicates existing capabilities, medium shading indicates enhancements to IMT-2000, and the lighter shading indicates new capabilities of Systems Beyond IMT-2000.

The degree of mobility as used in this figure is described as follows: Low mobility covers pedestrian speed, and high mobility covers high speed on highways or fast trains (60 km/h to ~250 km/h, or more).
