Wi-fidirect: Bluetooth terminator?

Our correspondent Huttrie/Wen has no network can also realize equipment Internet Wi-Fi Alliance recently revealed that a new standard Wi-Fi Direct will be completed, so that Wi-Fi equipment without access to traditional home, office or hotspot network, you can achieve mutual connection. In a live demo by the senior marketing manager of Wi-Fi Alliance, Sarah Morris, I also realized the significance of this new application. Sarah Morris used a regular camera with Wi-Fi to take a picture of the scene and immediately uploaded it to the media server. And the on-site Wi-Fi function of the mobile phone can be entered a set of password landing Media server to obtain photos.　　It is worth mentioning that the cameras and mobile phones used in the field only have the old Wi-Fi features. "Wi-Fi Direct has no additional requirements for hardware," Edgar Figueroa, executive director of Wi-Fi Alliance, told reporters. For some products, vendors can support Wi-Fi Direct with existing products by providing upgrades to the software. He added, "If the participating devices have Wi-Fi direct functionality, the experience will be much richer." "And, more importantly, the first benefit that Wi-Fi direct can bring is to extend the traditional personal LAN range from covering one room to covering the entire family."　　"It is reported that the Wi-Fi Alliance is scheduled to start in the middle of 2010 to the new standard certification, certified products will obtain Wi-Fi certified Wi-Fi Direct logo." Myron Hattig, WLAN standard director from Intel Mobile Wireless, said: "Hopefully this summer, we will be the first company to get the certification when Wi-Fi Direct certification is officially launched"; Stephen R.palm, technical director from the Communications division, said , "for Wi-Fi Direct has a new function is very much to look forward to, very agree with, hope that the relevant certification project this year when the launch, will soon have our (Bo Tong) through the certification of the product launch."　　"Bluetooth crisis?" The Wi-Fi Direct technology was released in 2009, and the public was quick to show a strong interest in it, and there were many views that it might mean the end of Bluetooth.　　To this, the Bluetooth alliance immediately reacted, and said Bluetooth 3.0 technology more advantages, more convenient to use. So what are the advantages of Wi-Fi direct technology compared to Bluetooth technology? The executive director of the Wi-Fi Alliance said in an interview with the world of communications that Wi-fidirect is better than Bluetooth in the following 5 points: "1th, it has WPA2 security performance; 2nd, it is ip-based and can be naturally implemented and all other ip-basedThe 3rd, the service scope is bigger (can reach two football field size), 4th, the transmission rate is higher, reaches 250Mbps; 5th, supports all existing Wi-Fi-enabled equipment. "It is worth mentioning that Wi-Fi Direct is not only available in the home, but also its security can fully meet the needs of enterprise users."　　It is reported that this standard can provide the management function for the enterprise environment, and has the WPA2 security performance. According to the report released by Abi Research2009 at the end of 2014, the number of Bluetooth chipset shipments is expected to be close to 2 billion, more than half of which will be used in wireless handsets; the same year, Wi-Fi chipset shipments are nearly 1.5 billion and more than 1/3 will be used on mobile phones. The report also noted that "Wi-Fi Direct can achieve point-to-point (peer-to-peer) communication between devices within a short distance, which will facilitate the development of Wi-Fi." "The competition between Bluetooth and Wi-Fi is going to be inevitable, and whoever wins will have to be judged by the consumer."
