New Wi-Fi Direct Gets peer-to-peer connections

Spec supports device-to-device connections over same range and as same speed as Wi-Fi, but without a hotspot or access point

A new specification, called Wi-Fi Direct, provides peer-to-peer connections between Wi-Fi devices, no hotspot required. That could be bad news for Bluetooth, but good news for customers.

Developed by the Wi-Fi Alliance, the new specification is expected to begin appearing in products as soon as next year. It will allow device-to-device connections over the same range and as the same speed as Wi-Fi, but without the need for a hotspot or access point, the alliance said.

This would allow Wi-Fi to be used for applications that previously have been best served by a Bluetooth connection. Indeed, the days of Bluetooth being considered a wireless replacement for a USB cable may be numbered.

By the end of next year, we may be using Wi-Fi Direct for the same purpose.

The Bluetooth Special Interest Group has not been sitting still, however, announcing a 3.0 specification back in April.

Wi-Fi Direct will also connect to traditional Wi-Fi networks as well as to groups of Wi-Fi Direct devices, the Wi-Fi Alliance said.

Security features have been built into the Wi-Fi Direct specification to prevent peer-to-peer devices from compromising corporate networks.

My take: This is great news. Wi-Fi has been hugely successful in helping build home and business networks, but peer-to-peer connectivity has been lacking. Either Bluetooth 3.0 or Wi-Fi Direct should be able to help. It will be interesting to see how the market shakes out. I am betting on Wi-Fi Direct.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
