Datang says WiMAX fails to meet 3G standards

WiMax, which was approved as a third generation (3G) standard by the International Telecommunication Union (ITU), fails to meet third generation standards actually, the Beijing Morning Post today cited a supporter of China's homegrown 3G wireless standard TD-SCDMA as saying.

"WiMax, based on the IEEE 802.16 standard, is unable to support seamless handover, and can't meet mainstream 3G standards," said Chen Shanzhi, vice chief engineer of Datang Telecom Group, one of China's leading TD-SCDMA vendors.

"In addition, the industrialization of WiMax is immature and many key technologies still need further testing," Chen added.

He also said that WiMax is a solution for wireless broadband access, but the Chinese government has organized experts to discuss the technology, finding it is not a good solution for mobile communication.

On October 19, WiMAX was approved as a 3G standard by the ITU, a United Nations agency that allocates radio frequencies for commercial use among its member countries, after the WCDMA, CDMA2000, and TD-SCDMA.

Chen also stressed that TD-SCDMA is indubitably an independently-developed technology and Datang holds key intellectual property right to TD-SCDMA.
