Wi-Fi Direct to Threaten Bluetooth


You may soon be able to transfer content between Wi-Fi-enabled devices in your home or office without having to set up a Wi-Fi router. On Oct. 25, industry association Wi-Fi Alliance began certifying consumer electronic gadgets that can connect directly to other Wi-Fi devices (http://www.businessweek.com/technology/content/oct2009/tc20091013_683659.htm). The technology is, in effect, an alternative to Bluetooth wireless connectivity.
Devices marked with the new Wi-Fi Direct label can connect to older Wi-Fi devices. Mobile phones, cameras, printers, PCs and gaming devices can now connect to each other directly to transfer content and share applications. Devices can make a one-to-one connection, or a group of several devices can connect simultaneously. How this might work: Your Wi-Fi Direct device will signal to other devices in the area that it can make a connection. You can view available devices and ask them to connect, or you might receive an invitation to connect to another Wi-Fi Direct device.
Chipmakers including Intel, Broadcom and Atheros have already announced Wi-Fi Direct products. If Wi-Fi Direct takes off, Bluetooth’s future may be murky.
