Wi-Fi Direct:and all wireless devices communicated


The Wi-Fi Alliance, which works on various flavors of Wi-Fi protocols, today announced that a newcomer would soon feel. Called Wi-Fi Direct, it allows two-point wireless to connect and communicate with each other without central access point.Formerly known as Wi-Fi peer to peer, this technology has very concrete applications. Family reunions Wi-Fi Direct is not really a standard designed for the network. As some have inferred, it is a killer Bluetooth.The purpose of technology is that all devices will have very different service discovery: they signal their presence and presents a list of their capabilities. Unfortunately for Bluetooth, Wi-Fi Direct is designed to kill literally. One can well imagine, for example:
• digital music player that synchronizes remote
• A digital camera that would communicate directly with the printer
• A camcorder capable of transferring its contents directly on a computer In fact, this new standard, already under certification from IEEE (Institute of Electricaland Electronics Engineers), could be used to interconnect telephones, keyboards, mice, webcams, printers or computers, and laptops.
Security and Performance
The Wi-Fi Direct has several interesting features clearly.First, any apparatus or device certified Wi-Fi Direct will be able to communicate with older Wi-Fi equipment, so if you have a digital camera with this certification, he can communicate directly with your printer Wi-Fi classic.There is little doubt that opportunities to exploit such a degree of wireless communications abound. The other interesting point is that this future standard (as said) is thought indeed for domestic use, but also professional.Thus, WPA2 is used as the base, while management functionality will be provided for businesses. And what about the speed for data transfers? It's simple, but there are two cases:
1.If you introduce a new Wi-Fi device in a park Direct Wi-Fi standard, he will communicate with the old equipment to the maximum speed of which they are capable
2.In the case of a set of products all certified Wi-Fi Direct, this will depend solely on their speed because the Wi-Fi Direct does not guarantee a connection speed special because it is certified "extra". A device could very well use the declination 802.11g and be Wi-Fi Direct. In the domestic world, however, it's likely that most facilities use declination N. The situation is identical to the signal range. Of course, compared to Bluetooth, Wi-Fi Direct does almost as benefits.The signal range and performance are in fact not much in common and the blue tooth was beaten soundly. But it is said "almost" because Bluetooth has the advantage of having a much lower power consumption to Wi-Fi, and version 3.0 will also change automatically login to use Wi-Fi when available. It's hard not begin to imagine a world where Light Peak and Wi-Fi Direct does not reign supreme.
