ARIB

Association of Radio Industries and Businesses. An incorporated body designated by the Ministry of Posts and Communication of the Japanese government to pursue effective radio utilisation in the radio communication and broadcast sector. With regard to standardisation, ARIB is currently primarily engaged in standardising procedures for IMT-2000 (next generation mobile communication system) and digital TV broadcasting.

ATM

Asynchronous Transfer Mode. Technology for high-speed transport (up to 6.22 megabytes per second) and switching of various types of data, voice and signals. In contrast to Synchronous Transfer Mode (STM) which always transfers a frame whether or not data for transmission is present, ATM transfers a cell to the network only when data to be transmitted actually exists. Hence the dubbing “asynchronous”.

BEARER

The name of the ‘virtual bit pipe’ carrying a particular end user service

BLUETOOTH

Short range radio technology expanding wireless connectivity to personal and business mobile devices enabling users to connect their mobile phones, computers, printers, digital cameras and other electronic devices to one another without cables. Bluetooth has begun to experience rapid proliferation, and is fast becoming a defacto world-wide standard. Nokia participates as a founding member in the Bluetooth Special Interest Group (SIG). Current membership inSlG comprises over 1300 firms from all over the world.

BTS

Base Transceiver Station. Although specifications differ for each system, the BTS effects radio communication with mobile stations (MS) via its respective radio access system and transmits/receives signals to/from connected radio network controllers (RNC) located along transmission routes.

CDMA

Code Division Multiple Access is one type of multiple access system used in radio communication. Other multiple access methods include TDMA, FDMA, etc.

CDMAONE/IS-95

Interim Standard-95 is one type of digital mobile phone system which applies CDMA to realise large volume traffic and enable numerous users to access a limited bandwidth. Also known as cdmaOne, this system is used in Hong Kong, North and South America, Korea and Japan.
