More on Bluetooth: (Courtesy of mmbull at RB) M2 PRESSWIRE-24 September 1999-NEC: NEC develops W-CDMA mobile videophone (C)1994-99 M2 COMMUNICATIONS LTD NEC Corporation (NASDAQ: NIPNY, FTSE: 6701q.l) announces that it has developed a prototype of a W-CDMA (Wideband-Code Division Multiple Access) mobile videophone based on the next-generation mobile communications system "IMT-2000". The videophone is a combination of a mobile phone handset with a viewer, comprising screen, video camera and microphone (1). The third-generation mobile phone system, which is now in the process of standardisation, aims to achieve data transmission speeds from 30 to 100 times higher than current rates (384Kbps for mobile, 2Mbps for static). Ultra-high voice clarity and mobile multimedia applications including video, large-capacity data and Internet access can all be possible through this system. The W-CDMA system also utilises frequencies efficiently, allowing more subscribers to share the system. NEC's prototype W-CDMA based mobile phone handset is a compact and lightweight (120cc, 130g) foldable design. The viewer (240g, 260cc) comprises a small CCD (Charged Couple Device) camera, microphone and 2-inch color TFT-LCD screen. It employs the latest video and audio compression technology (MPEG-4 Visual (2), H.263 Ver.2 (3), MPEG-4 Audio/CELP (8kHz/16kHz Sampling) and G723.1 (4)) to enable the phone to realize high quality audio and video, Internet access capabilities and large capacity video streaming. In addition, the hands-free function enables users to converse whilst watching the screen. To enable wireless connection between the phone handset and the viewer screen, NEC is using Bluetooth technology, the latest standard for short-distance radio communications (*5). Bluetooth technology works by connecting information terminals using omni-directional radio signals The ability to separate the viewer from the mobile phone makes the phone highly portable and therefore convenient for use on the move without connection cables or directional infrared connection. Thus, the phone can remain in your pocket whilst the screen and camera are in operation. NEC will develop its commercial product based upon the prototype and will be demonstrating this prototype, along with W-CDMA network systems at the TELECOM99 and INTERACTIVE99 exhibitions, to be held in Geneva, Switzerland from 10th October 1999. NEC is involved in the development of W-CDMA for NTT DoCoMo in Japan and was chosen to supply the W-CDMA network system and handsets for NTT DoCoMo's commercial mobile network. NEC is also actively involved in the field of W-CDMA, through the pursuit of technical verification for radio interface and is participating in global standardisation activities. Last year, NEC established two development companies outside Japan to assist in the research of third-generation mobile communications: Telecom MODUS Limited in the UK and NEC Mobile Communications Development Singapore Pte. Ltd. In March 1999, NEC also formed a strategic alliance with Siemens AG for the Third Generation Mobile Telecommunications System to combine the two companies' technological strengths and know-how in this field. NEC has already been conducting W-CDMA technical trials system with Telephone Organization of Thailand (TOT) and British Telecom. NEC's development division in Japan, NEC Technologies (UK) Ltd. and NEC Australia Pty Ltd. are all actively involved in the development of the handsets. NEC expects its global development bases, vast experience, and expertise in the field of mobile communications to facilitate the timely introduction of W-CDMA systems and handsets offering sophisticated multimedia features delivering performance and reliability in a cost-effective manner, and allow NEC to become a major world supplier of next-generation mobile communications systems. 1) The mobile phone handset is developed jointly with NTT DoCoMo. 2) MPEG-4: ISO/IEC international standards for video and audio compression in multimedia communications. 3) H263 Ver.2: ITU-T international standards for video compression 4) G723.1: ITU-T international standards for voice compression. The prototype is application of MPEG-4 technology developed in NEC Central Laboratory and NEC Semiconductor Group 5) Bluetooth: Low power radio communication system meeting the IEEE802 standard. Common specification is in progress by semiconductor suppliers and equipment suppliers to enable connection of personal computers, portable telephones and other OA equipment without cables.

TOKYO, Sept 28 (Reuters) - Japanese electronics group NEC Corp said on Tuesday it would embark on 100 billion yen ($939 million) restructuring programme this year to transform itself into a lean, Internet-based firm. ''We will put every resource into our Internet operations, using our Internet service provider BiGlobe as its driving force,'' president Koji Nishigaki told a news conference. ''With strength in parts, telecommunications equipment and computers, NEC is best positioned to benefit from the Internet revolution.'' Reflecting this approach, NEC said it would announce a business alliance with U.S.-based Intel Corp (NasdaqNM:INTC - news) in the Internet area on Wednesday morning. It declined to give further details. Might not affect us, but could be interesting, TR
