IrSimple, a High-Speed Infrared Communications Protocol Adopted as a Global Stan

ITX E-Globaledge Corporation, NTT DoCoMo, Sharp Corporation and Waseda University have jointly developed IrSimple*1, a high-speed wireless communications protocol using infrared. IrDA*2 (Infrared Data Association), an industry organization that develops and standardizes specifications for infrared communications, has decided to formally adopt the protocol as its standard. IrSimple achieves faster data transmission speeds (at least 4 to 10 times faster than at present) by improving the efficiency of the current infrared IrDA protocol embedded in many mobile devices such as mobile phones. In addition, the IrSimple protocol also maintains backward compatibility with the existing IrDA protocols.

Renesas Starts Sample Shipments of Dual-Mode Chips Developed With NTT DoCoMo

Renesas Technology Corp. today announced it has started shipping evaluation samples of a single-chip LSI, jointly developed with NTT DoCoMo, Inc. for dual-mode mobile handsets supporting W-CDMA (3G) and GSM/GPRS (2G) systems. Evaluation samples have been available for customers since the end of July 2005. With technological development investment from NTT DoCoMo since July 2004, the jointly developed LSI is expected to promote the global use of FOMA(R) and similar 3G mobile handsets. It also reduces costs by incorporating a dual baseband processor handling W-CDMA and GSM/GPRS systems together with a Renesas Technology SH-Mobile application processor.

With three new carriers set to enter the domestic market in 2006, the dominant telco is said to be considering how to defend its market share by offering new services and incentives. Opinions suggest the company will respond to the popular, though as yet still not widely used, flat-rate voice services launched by Willcom in May this year and the family free-call trial running on Vodafone from July through the end of October.

Japan Allocates 2-GHz Spectrum for TD-CDMA

Last week, the Japanese Ministry of Internal Affairs and Communications announced that Japan’s 2010 – 2025 MHz spectrum would be allocated solely to IMT-2000 TDD technologies. This paves the way for broadband wireless networks using UMTS TDD, also known as TD-CDMA in Japan; the first commercially deployed IMT-2000 technology for unpaired spectrum. Optimized for high-speed data, UMTS TDD is already used by operators and manufacturers worldwide and has emerged as a leading standard for Broadband Wireless Access.
