Kyocera Testing iBurst

Kyocera has obtained a permit from the government to begin experiments of the “iBurst System,” ArrayComm’s wireless technology with maximum downstread of 1Mbps, and has begun testing the technology inside of their Yokohama office. The system is said to have a data receiving capability of a maximum of 1Mbps. Based on the TDD standard, a service using iBurst began in March of this year in Australia. The companies offer base station access via PC cards to clients on a monthly flat-rate data service package.

Fujitsu Develops Breakthrough Technology for Mobile Base Station Amplifiers

Fujitsu Laboratories Ltd. today announced the development of a technology that enables low-cost production of gallium-nitride(GaN)(*1) highelectron mobility transistors(HEMT)(*2), a key technology in mobile base station amplifiers for 3G and beyond. This breakthrough technology reduces GaN HEMT production costs to less than one-third that of conventional levels, thereby contributing to the realization of lower-cost GaN HEMT-based amplifiers. The technology is designed to enable practical use of compact, more energy-efficient mobile base stations using GaN HEMT. Details of this technology were presented at the International Electron Device Meeting (IEDM) 2004 held in San Francisco last week.

DoCoMo Tests 4G Speed

DoCoMo said today that this past summer they successfully achieved a 1-Gbps high-speed packet transmission (downlink) in a laboratory experiment using fourth-generation (4G) mobile communication radio access equipment, and are considering field experiments early in 2005. DoCoMo achieved 100- and 20-Mbps data rates in the downlink and uplink, respectively, in outdoor environments at a moving speed of about 30 km/h in July 2003.

Dilithium Networks' AnswerFast™ Plus Reduces 3G Video Call Set-up

Dilithium Networks, the leader in 3G video telephony solutions for the world’s mobile and broadband industries, announced today that it has successfully demonstrated its new AnswerFastTM Plus technology, over live 3G networks in the UK and Australia. With AnswerFastTM Plus, Dilithium Networks successfully demonstrated that video calls can be set up in less than 1 second, resulting in call setup times that are comparable to those of voice calls. Present 3G terminals typically take 6-10 seconds to completely establish the audio and video channels.

KDDI Unveils MS Wi-Fi Phone

KDDI and Fujistu have introduced a prototype smart phone, or “hybrid information terminal,” that will be available to visitors attending the Aichi World Expo 2005, which begins here in March and runs through to the end of September. The ‘Love and Mate’ [.jpg] (yes, that’s what they’re calling it) handset comes in Orange and Blue; both feature Windows Mobile 2003 Second Edition for PocketPC software for PDA and phone operation, and Windows Media Player 9. This is one of the first deployments of Windows on a phone in Japan.

NEC Sells MIR Solution to Telefonica Moviles Espana

NEC Corporation today announced that it has received an order for its Messaging Intelligent Router MMS (MIR) solution from Telefonica Moviles Espana, S.A., Spain’s largest mobile operator with 18.7 million subscribers. With a population of 41.11 million people and an 83% mobile phone penetration rate, Spain boasts one of the highest levels of mobile phone penetration in Europe. The MIR Solution is a server software system that can easily be added on to existing MMS (Multimedia Messaging Service) and mail server systems of mobile operators. The MIR solution is an advanced, new method to extract necessary data from MMSs and transfer it to a charging system enabling flexible and attractive charging menus.
