The Wi-Fi Alliance announced Monday that it has begun certifying products for compliance with the Wi-Fi Direct standard, aimed at enabling router-free instant networking among Wi-Fi enabled devices (a la Bluetooth).
Technically, Wi-Fi Direct does not dispense with access points, but merely relies on a software-based alternative, called Soft AP, allowing any Direct-enabled device to act as an access point. A Wi-Fi Direct connection is not only way more uncomplicated than traditional peer-to-peer Wi-Fi connections (ad hoc), but it is also much more secure. It is being tipped by many to be Bluetooth's replacement -- and not without good reason. Bluetooth simply can't match Wi-Fi Direct in terms of range and speed.
