Typically, Wi-Fi works in what is known as Infrastructure mode, where each device communicates through an access point to other devices. Bluetooth technology eliminates the need for this intermediary device and allows devices to communicate directly with each other.

Bluetooth may have one advantage in that it has very low power requirements, but the speed and range of Wi-Fi Direct will make for some interesting applications. I’m looking forward to using wireless stereo headphones all the way out into the garage.

The new standard raises the theoretical transmision speed to 450 Mbps. This is a leap forward compared to the previous standards of 54 Mbps.

New devices should be available for the holiday season. Look for the Wi-Fi Alliance seal to make sure the device is certified.
