Support for China-Developed WLAN Standard
China has made progress towards the implementation of a domestically developed wireless local area network (WLAN) standard with the release of the first batch of products compatible with the Chinese standard. The Broadband Wireless IP Standard working group (BWIPS), a major player pushing for the Chinese WLAN authentication and privacy infrastructure (WAPI) standard who developed the WAPI protocol, has released the first wireless network card in compliance with Chinese standards. The release of the first WAPI-compatible network card means that Chinese companies have succeeded in developing home made WLAN hardware, a critical step for promoting the Chinese standard.

China Develops High Power LED Chip For Illumination
A powerful LED (light-emitting diodes) chip used for illumination has been developed by a Chinese high-tech company, China Fangda Group in Shenzhen. Two to three semiconductor chips of this kind are able to form a high-powered illumination. Usually, over 100 semiconductor chips are needed to make a reading lamp. The Chinese government has listed high-powered LED semiconductors as one of the major scientific and technological research projects during the period of the tenth Five-Year Plan (2001-2005).
