China wireless national standard: when going through
(2004-02-17 08:41:36)
Communication standards are a crucial area in the current information industry competition, and countries pay great attention to this. Among them, the competition between international communication standards is particularly fierce. For example, in the third generation of mobile communications, TD-SCDMA Technical Recommendations in China will eventually become one of the three mainstream standards of the international third-generation mobile communications, which has been a fierce competition for nearly three years. In recent years, Wireless LAN (WLAN) has got a long-term development, and has become a hot spot in the communications industry. The International Standards organization also developed a range of standards for WLANs. In 2003, a national standard proposed in the WLAN field suddenly caused huge vibration and attracted the global industry's gaze. WLAN development is trapped in security issues with continuous maturity of wireless communication technology and the expansion of Internet applications, and Wireless LAN (WLAN) is increasingly a hot field of communication. In recent years, WLAN has exceeded 100% in China, and it is concerned about the world. However, domestic industry persons pointed out that for my country and the world's WLAN market, due to serious safety defects in the existing international standards, the standard upgrade will be generally facing in 2003. In order to alleviate the pressure from the industrial and end users, IEEE, to ease the pressure from the industry and end users, and start certification in 2003, but still did not fundamentally solve the problem, because WPA is still very Severe defects. Even members of the Wi-Fi Alliance that push WPA also expressed the dissatisfaction with WPA, and considered WPAs were a bad choice, and it was 802.11i's extension of power. At the same time, the Certification progress of the WPA standard is not satisfactory. Since the implementation of WPA, the certified product is not 20% of the total market, it is not difficult to see that WPA is very limited. Analysis believes that 802.11i standards expectated by the industry, such as an officials of the IEEE Standards Organization, to be officially passed in the third quarter of 2004, comprehensively enforce certification to wait until 2006. According to the popularity of WPA safety standards, in 2006, it is difficult to more than 50% in accordance with the 802.11i of WLAN products. According to the high growth rate of the Chinese WLAN market, the construction stage of the operator's public WLAN infrastructure will be basically completed. WLAN products with secure defects will become "fact standards" in Chinese enterprise users, personal users, 802.11i standards will become "late standards". Considering the interests, security needs of China Wireless LAN, China proposes its own wireless local area network standard. Wireless national standard horizontal air born on May 12, 2003, the China Broadband Wireless IP Standard Working Group is responsible for drafting two national standards of Wireless LANs "Information Technology System Remote Communication and Information Exchange LAN and Metropolitan Network Specific Requirements Part 11: Wireless LAN Media Access (MAC) and Physical (PHY) Layer Specifications "," Information Technology System Remote Communication and Information Exchange LANs and Memberspace Specific Requirements Part 11] Wireless LAN Media Access (MAC) and Physical (PHY) Layers Specification: 2.4GHz frequency band is higher than the high-speed physical layer expansion specification "(hereinafter referred to as wireless national standard), which is issued by the Ministry of Information Industry to the National Standardization Management Committee formally promulgated. It is reported that the release of the wireless national standard is to fully consider the interconnection interconnection, and from China Wireless LAN users, standard security, wireless local area network market demand and norms Fully combine the relevant laws and regulations related to our information industry.
On July 9, 2003, the Ministry of Information Industry, the National Standardization Management Committee, and the National Password Management Committee office jointly held two wireless national standards in Beijing, and the deputy director of the National Development and Reform Commission High-tech Industry Development It is said that the issuance of the national standards of wireless LANs is of great significance to the development of my country's next-generation network technology, and the standard formulation has been supported by relevant departments of governments and will effectively drive the development of the industry. Deputy Director, Secretary for Science and Technology, Ministry of Information Industry, believes that the standard development must be established on the basis of full considering industrial development, strictly abide by the relevant laws and regulations of the country, and the process must standardize, and the broadband Wireless IP Standard Working Group launched these two The process of national standards is reflecting this requirement. Subsequently, the relevant state departments have issued an announcement, identify the period of the wireless national standard, which is determined: from June 1, 2004, Wireless LAN products that have not been obtained from the mandatory product certification and the uncomfortable China mandatory certification mark Not allowed to use, import, sales, or in other business activities, from January 1, 2004, the client can propose certified products to the designated agency and certification. The above series of high-profile initiatives fully demonstrate the government's support and implementation of the government for wireless national standards. Wireless national standard sets a wave of waves, although the Chinese government is only the domestic standard, does not affect the use of wireless local area network products from other countries and regions. But this will still set off an uproar. At the end of January 2004, chip vendors, including Broadcom, including the world's largest wireless network, said that these rules require foreign suppliers to share strictly protected design materials, so that their knowledgeability is threatened; Wi-Fi Alliance In charge of Etton, if these rules have not been compromised in June, Wi-Fi chip manufacturers will consider stop selling Wi-Fi chips to China. And other domestic and foreign manufacturers have also performed this, and the domestic enterprises such as Lenovo are more active. It is a great time to reverse the status quo of foreign counterparts, and most foreign companies express "China 's wireless national standard, But there are also some companies expect to exchange the results of the Chinese government, and some companies have expressed their understanding and supporting China's wireless national standard, and said that the standard products are introduced as soon as possible. International Standards Organization IEEE officials said that it is expected to avoid two standards while existence because it may lead to two wireless network equipment markets. As a result, the progress of the smooth wireless national standard is pushed into the tip of the wind. Especially for the problem of Wi-Fi chip for sale, there are many fears in China. Some people have suggested that what will I have a computer that has installed wireless local area network cards? Will China 's wireless local area network rapid development trend will be affected by "ban"? For American manufacturers, "the last pass" and the domestic doubts, Liu Chaoyang, China Broadband Wireless Standard Working Group, said Liu Chaoyang showed a very resolute attitude in the conversation. He believes that there is no Wi-Fi alliance, the sky in China WLAN market will not collapse, because my country's WLAN industry chain has been slightly prototype. Some major laptop manufacturers also said that users can get a wireless network access service that meets the new wireless national standard by upgrading. Although the situation has not further developed, foreign manufacturers will seek to reduce the impact and restriction of China's wireless national standard for them to enter the Chinese market. After all, China's market capacity is huge, and the temptation is not ignored by any company. At the same time, from this dispute we can also see that the road to China's information industry to participate in the world competition must be full of difficulties. Due to the lack of technical backwardness and self-protection awareness, we have faced the monopoly of some markets in China for foreign companies. And we will take a huge price every time you take a step forward.
Therefore, some people call for our industries that our industries need to be aware of the crisis. Chinese companies need to improve core technology competitiveness. At the same time, the leaders of the government have needed to play in developing national technology and industries. . Background Information: China Wireless LAN Technology National Standard WAPI WAPI (WLANAUTHENTICACPRIVACYINFRASTRUCTURE), that is, wireless LAN identification and confidential infrastructure, which is aimed at the IEEE802.11 WEP protocol security issues, multi-party participation, repeated argument, and fully considering various applications Mode, the WLAN security solution proposed in China Wireless LAN National Standard GB15629.11. At the same time, this program has been reviewed and approved by IEEEREGISTRATIONAUTHORITY (IEEE registration authority) authorized by IEEEREGISTRATIONAUTHORITY, which is allocated for WAPI protocols, which is the only agreement that my country is currently approved in this area.
