Development of Millimeter-Wave Intra-connection Wireless Technology by SONY
Millimeter waves are electromagnetic waves with a frequency range of between 30GHz to 300GHz, and wavelength between 1mm to 10mm. With their inherent high frequency, millimeter waves are best suited for ultra high speed data transfer. Their advantage goes further through their ability of transferring data in such high speed with use of very small antennas. With today’s multi-functional electronic equipments there is an increasing amount of internal data transfer which wired connected approach will soon its limit in data capacity, requiring an additional circuitry to accommodate a larger data transfers, however this approach will result in increasingly complex IC packages, intricately printed circuit boards not to mention a larger IC sizes. Millimeter wireless technology offers a promising choice in fulfilling this need. Base on this technology and in the face of coming shortage in data capacity, Sony made an announcement on development of millimeter wave wireless intra-connection technology capable of high speed wireless data transfer inside electronic products such as television sets.

Development of World’s First Gallium-Nitrate Transceiver Amplifier Chip set by Fujitsu
High-bandwidth wireless technology has been considered for sometimes to be the most viable alternative to fiber-optic cabling in a heavily build-up as well as surface areas with difficult topography throughout Japan. The technology on par with fiber optic cabling is capable of data transmission of 10 Gbps. An effective band to be used for such wireless communication managing faster than 10Gbps would be the millimeter-wave band ranging from 70 to 100 GHz. But in order for this technology to be practical and successful the transmission distances would need to go beyond several kilometers and to several tens of kilometers. Read more
Development of Spatial Audio Transmission Technology for Mobile Phones
NTT DoCoMo has unveiled a newly developed spatial audio transmission technology for mobile phones capable of assigning a spatial position to each sound source when a user is listening to multiple sound sources for example during a game or a conference call. Through this technology the user is able via the headphone to hear each speaker’s voice as if they were coming from a unique direction creating a virtual face-to-face communication environment. DoCoMo’s planned target for this newly developed technology is for use in mobile conference calls, tele-education and online games according to DoCoMo. Read more
