WiFi point-to-point connection will come true next year
as we all know, the premise of current Wi Fi applications is that terminal devices must be under the hot spot coverage, that is, Wi Fi network, before they can carry out a series of interconnected applications. Then, can Wi Fi devices still realize point-to-point connection for data sharing like Bluetooth devices without network? The answer is yes, and the Wi Fi alliance is working to launch this point-to-point connection solution called wi fidirect in 2010
with Wi Fi point-to-point connection, the high-speed communication of information will become more convenient and fast. When edgarfiguerao, the executive director of the Wi Fi alliance, introduced this technology a few days ago, he couldn't hide his excitement: "now, I connect the computer and the projector through a cable to give a speech to you; you can imagine that with Wi Fi point-to-point technology, the computer can realize a wireless connection with the projector, and I can also send the photos I took directly to the projector."
wi fi point-to-point connection will bring a variety of applications. Between two or more devices, high-speed information channels can be established without Wi Fi network to realize various applications, such as directly printing photos taken by cameras or in, directly sharing music and synchronizing contacts with friends who are the target friends we have been chasing, directly displaying pictures or videos in mobile devices on TV, and playing video games with friends on different mobile devices. Moreover, these applications are almost the same as the experience in Wi Fi network environment, because point-to-point connection will also retain the reliability and ease of use of Wi Fi network
industry cooperation and joint development ensure that Wi Fi point-to-point connections can be interoperable and widely available. For Wi Fi point-to-point connection, all Wi Fi devices, such as cameras, printers, televisions and other electronic devices, must comply with certain technical standards to realize barrier free connection. This h) process is realized: the experimental process, measurement, display and analysis are completed by computers; The advantages of this technology can be brought into full play. Edgarfiguerao said, "we are bringing together the power of the whole industry and developing it together, rather than each enterprise acting in its own way. Then, based on the very mature technology development process of the Wi Fi alliance, we will develop technology certification projects and provide them to the world. Such a development process is proven and very effective." Therefore, Wi Fi point-to-point connection requires that devices must pass the testing and certification of some core technologies provided by the Wi Fi alliance, or have interoperability. These core technologies include 802.11n and 802.11a, B or G standards, which are currently widely used by Wi Fi. Another key requirement is that devices with Wi Fi point-to-point connection must also support security protocols
the emergence of point-to-point connection technology will undoubtedly push the Wi Fi market to a new peak of development, and will play the role of the main force. At present, it is becoming the most popular Wi Fi device in the world. A survey completed by abiresearch this year shows that 77% of American Wi Fi users are more satisfied with them than non Wi Fi users; 60% of the surveyed Chinese Wi Fi users will consider buying a Wi Fi in another 12 months. It is reported that at present, 375 models have been certified by the Wi Fi alliance, and the certified models in 2009 will be about twice as many as those in 2008. The survey data also shows that the packaging film has a decisive contribution to the large-scale process with special capacity, and is expected to become a low-cost alternative material for medical trials. In the next few years, Wi Fi will grow rapidly, and the shipment volume will increase from 102million now to 300million in 2011. China Information Industry ()
