Number of family disputes resurgence?? WirelessHD group to promote the 60GHz wireless technologyToday, was acclaimed as the most promising wireless technology of the 60GHz “millimeter wave” technology, has been out of the laboratory into the real electronics world one of the most competitive areas?? Digital home. Recently, six major supplier of consumer electronics giant WirelessHD group set up to regulate on 60GHz technology, this technology can 5Gbps in the living room up to speed transmission of uncompressed high definition video data. This from the LG, Panasonic, NEC, Samsung Electronics, Sony and Toshiba team, will be released in the spring of 2007 to connect a standard range of 10 meters. In the foreseeable future, with the emerging technology will have the 1394FireWire, HDMI, 802.11n and UWB technologies to compete. “Absolutely can not predict now whether a technical success, but I think this is difficult to predict future occurrence.” Farpoint Group analyst CraigMathias said, “From the beginning of this year, the Consumer Electronics Show (CES), we you can see some clues. ” Business and academic researchers have long been promised to achieve the characteristics of 60GHz. This band can be used without permission of the bandwidth of up to 7GHz, but really want to achieve together, but difficult. Fortunately, WirelessHD group has been supported by start-up company SiBeam, the company from the University of California, Berkeley researcher BobBrodersen created, he is a pioneer in the field of RF CMOS. In the future development, WirelessHD will require the talents in various fields, as 60GHz technology challenges facing the design, simulation and testing ultra-high-speed circuit, to establish a highly accurate and adaptable antennas everywhere. From a commercial point of view, transmit uncompressed digital HD video program from the United States Security Agency faces scrutiny in Hollywood. Moreover, WirelessHD has not yet finalized the form of business model or royalties. 60GHz wireless technology advantages While home networking is not considered the smallest, cheapest and lowest-power technology, but the bandwidth of 60GHz technology is a trump card. Transmission resolutions up to 1,920 x1, 080p uncompressed high-definition video, and the delay in milliseconds between 5 and 15?? This is the WirelessHD group to seize the value of points. WirelessHD chairman JohnMarshall said that if the use of 60GHz radio technology instead of UWB, TV, DVD players and other HD transmission equipment can actually provide higher resolution and smaller delay and lower cost. Because the typical 480Mbps UWB bandwidth needs of data packets or broadcast video signals and then compressed, forcing the OEM system vendors placed in their expensive decoder, and more RAM, but there is in the process increase the video content loss and delay phenomenon. “Although I am not the eyes that, but I was able to identify after the lossy compression through 2 HDMI uncompressed image and the difference between images.” Marshall wryly. Although the Working Group Marshall declined to be specific progress, but we know that, WirelessHD 60GHz product development group is a cover for the physical layer to application layer from the various parts of the complete specification. The specification for the “mainstream of point to point” connections, but it does include a reverse rate of less than 100Mbps channel, he said. Since the maximum transmission range only 10 meters and can not penetrate walls, so 60MHz wireless technology is not eager to become a coveted post-election throughout the home networking technology. But the technology can be bridged to any existing home network, even though the specification did not bridge special provisions. SiBeam forecast the company’s Brodersen, 60GHz wireless technology may be required to achieve the commercial of the year or so. In order to meet the directional antenna array, the end-to-market product may be packaged in one square inch of the module, the power consumption of 5W or less, by cable network will link a small amount of additional loss, he said.
