The Application Of McWiLL In Video Monitoring On The Sea In The Olympics Sailing Events

McWiLL technology is a broadband wireless access technology self-developed by Beijing Xinwei Telecom Technology Corp., which masters the whole intellectual property. The Beijing 2008 Olympic Games provides new stage for domestic McWill technology application. The application of McWill in Qingdao Olympic Sailing Events will better reflect the tenet of "Hi-tech Olympics" , which will make 2008 Olympic Games better reflect Chinese characteristics, will improve the international influence of our country in the field of broadband wireless communication, and promote the widely application and promotion of domestic self-developed communication technology.This article makes deep discussions on the McWill technology' s function of video monitoring on the sea in the Olympics Sailing Events on the basis of making introduction to the physical basis of McWill test network.This article first generally introduces the synchronous CDMA,CS-OFDMA,intelligent antenna,Software Defined Radio,self-adaptive debugging method,air SWAP + wireless interface signaling,multi-carrier transmission technology etc. of McWill technology, then introduces Qingdao McWill network built by Qingdao Netcom and Beijing Xinwei Corp., the physical basis of McWill technology applied in Olympics Sailing Events. The McWill network built and completed by Qingdao Netcom covering the land area of Qingdao Olympics Sailing Center and Game sea area is the object of the first phase of McWill technology application. Meanwhile, the test on the performance index of McWill network is the second phase of McWill application in the Olympics sailing Events. At last, on the basis of test, Qingdao Netcom and Olympics Sailing Events Committee choose the video monitoring on the sea based on McWill technology as the demonstrative application in the Olympics Sailing Events. Utilize the broadband wireless access system function of McWill to proceed video monitoring on the sea, and install cameras on the starting boat in each game area to send the game picture to the screen of technology operation center and media center hall so as to be convenient for the game organizers to know the status of the game area, and be convenient for the media journalists to master the game information in the first time; the video recording function can be realized through the video relay server, which is convenient for the arbitration committee to arbitrate the disputes. This will be the first time to apply McWill technology in the Olympics Sailing Event in the history, the demonstration effect will promote the development of McWill industry in the whole country.
