Analysis of Intel WiMax roadmap plan At a time when global 3G has not been finalized, wireless communication technology WiMax has quietly debuted. Some industry insiders pointed out that with the strong support of semiconductor Intel, WiMax may rewrite the future wireless communication pattern. WiMax: the world's third largest broadband line WiMax (World Interoperability for Microwave Access) is also known as IEEE802.16a standard, or Broadband Wireless Access (BWA standard). WiMax is used to connect 802.11a wireless access hotspots to the Internet, and can also connect companies and homes to wired backbone lines, so it can be used as a wireless extension technology for cables and DSL to achieve wireless broadband access "Last Mile" question. WiMax and Wi-Fi belong to the same type of technology. Wi-Fi is a short-distance wireless access technology for homes and enterprises. When the Wi-Fi wireless access range is 150 feet, WiMax allows users to wirelessly access the Internet within 30 miles, transmitting data, voice and image data, but using WiMax wireless within 3 to 5 miles The effect of Internet access is more ideal. The advantages of WiMax over Wi-Fi are mainly reflected in that Wi-Fi solves the wireless LAN access, and WiMax solves the access problem of the wireless metropolitan area network. Wi-Fi can only transmit the signal of the Internet connection to 300 feet away, and WiMax can transmit the signal at least 31 miles. Wi-Fi network connection speed is 54 trillion per second, while WiMax is 70 trillion per second. The few technical comparisons between 3G and WiMax also disturbed the 3G camp. The former's network speed is 30 times slower than the latter, and in the network coverage area, the coverage of a 3G base station is only one-tenth of WiMax. In the past few years, wireless operators have invested hundreds of billions of dollars in order to obtain 3G operation licenses, and they are currently spending tens of billions of dollars to operate 3G networks. The WiMax radio frequency does not need to spend money to purchase, and based on this technology, the number of base stations required will be greatly reduced than 3G. In April this year, the WiMax Forum, a group aimed at promoting wireless broadband access, was formally established, and more than 25 communication equipment companies have joined. This forum is equivalent to the Wi-Fi Alliance of wireless LAN IEEE802.11, and its goal is to promote the application of WiMax. The chairman of the forum declared WiMax "the third largest broadband line after CATV and DSL lines". Intel promotes communication convergence At the 2004 Intel Information Technology Summit IDF, authoritative sources said that WiMax will enter the popularization period in 2005-by the first half of 2005, it will first be used outdoors, and in the second half of 2005, after the production of small base stations Indoor use. By 2006, its miniaturization will reach the level available for portable terminals. On April 21, 2004, telecommunications consulting firm BWCS and Senza Fili ConsulTIng jointly published a research report that predicted that WiMax will be a very popular wireless broadband technology. Semiconductor giant Intel is particularly hard working to support WiMax. IT observers say that thanks to the chip giant's strong support, the Wi-Fi market is growing rapidly, and WiMax is likely to become the "second Wi-Fi." No industry giant is as sensitive to disruptive innovation as Intel. In fact, the history of Intel's rise is to rely on constantly destroying itself, competitors and even subvert the pattern of the entire industry to achieve breakthrough progress. At the Intel Information Technology Summit in the spring of 2004 in San Francisco, the United States CEO Craig Barrett declared that the convergence of computing and communications has further increased the demand for technology from business users, and digital technology has become a new round of technological innovation. Core strength. Large-scale use of digital technology and continuous technological evolution will bring about a complete transformation in the global business, entertainment and communications fields. Intel has clearly made communication one of its main directions for the next phase. Sean Maloney, executive vice president and general manager of the communications business unit, said: "At present, the integration of communications and IT technology has become the company's main business." Hans Geyer, vice president and general manager of the network and storage business unit at Intel, hopes that Can occupy 64% of the world's remote or newly developed areas. In view of cost pressures, these areas have not been covered by broadband, and the development of wireless broadband access in these areas is particularly beneficial to WiMax. The Mobile Internet PC that Intel has shown in the past is the future concept of a laptop. Mobile Internet PC will have a variety of different wireless transmission technologies, such as Bluetooth, WLAN, etc., so that notebook computers can roam and switch various wireless networks anytime, anywhere. The biggest change is that the notebook will have wireless WAN networking technology. In this context, Intel spares no effort to promote WiMax. WiMax roadmap plan WiMax is a very hot topic within Intel, and management discusses its development up to three times a week. Intel introduced the WiMax technology at the IDF conference in 2003, and then gave a more specific product timetable in early July this year, which is called Intel's "WiMax roadmap plan." In 2004, WiMax technology will appear in the Internet for corporate hotspots and leased home networks; in 2005, WiMax technology will be extended to broadband networks for small businesses, home businesses, and consumer markets WiMax technology will be used in mobile phones in 2006 and began to be used in notebook computers; WiMax technology will develop rapidly in the field of notebook computers in 2007; in 2008, half of the world's notebook computers will use WiMax technology. Intel predicts that the cost and power consumption of wireless networking notebooks will fall further. The Chinese market will occupy an important position in the Intel WiMax roadmap-in terms of technical characteristics, WiMax is very suitable for China. In June of this year, Intel signed agreements with China's Dalian and Chengdu to deploy WiMax technology. According to the memorandum of understanding signed by Intel and the two cities, Chengdu and Dalian will set up the latest WiMAX broadband wireless technology, and enterprises and families will be able to use wireless methods for broadband connection. "Wi-Fi is that we are holding a laptop to find access points everywhere, and WiMax is that it is looking for us with a searchlight on it, and as soon as we turn it on, it will actively serve." Network technology will further change the business operation model and the way of communication and management of information on a global scale. In the context of global economic integration, the creative use of wireless broadband technology will increase the competitiveness of cities. " Intel also announced that it will establish an antenna laboratory in Taipei to support product testing and accelerate the time to launch new products in the Asia-Pacific region. Intel established its first application and design center in Taiwan, China in 1995, and established an innovation center in 2003. This is the second time Intel has succeeded in Centrino's success in putting technology into its chip products. "Business Week" compares WiMax technology to "Intel's powerful weapon for enterprises to quickly enhance its strength." If this move succeeds, the huge rewards of this approach will be sitting on $ 77 billion worth of home appliances, wireless Equipment and communications equipment market, and Intel currently accounts for less than 6% of the market. Industry insiders pointed out that in the current situation where the semiconductor industry is beginning to recover, Intel is trying to use its leadership in the chip market to use these new ideas to further ensure the profit prospects for the next few years. Although some areas seem to be far away from its core business, Intel has never skimped on "teaching" in the field of new technologies and sponsored other manufacturers to jointly build a value chain. Intel has a huge business prospect in the field of communication convergence. "There are one billion PCs and one billion mobile phones in the world.
