Here’s something new for us to know. Perhaps this might also kill off Bluetooth. This was talked about quite some time ago by the Wi-Fi Alliance, but there’s no news until recently. They’re ready to push this new technology called ‘Wi-Fi Direct’.Here’s how it works.
In order to make a direct device-to-device connection over WiFi, just one of the two needs to be Wi-Fi Direct certified. In other words, a Wi-Fi Direct printer can recognize and interface with your Latitude D410 laptop from 1999, as all Wi-Fi Direct certified devices have to be able to control the one-to-one relationship. The goal here is pretty simple — it’s to create a protected connection between two devices over WiFi with as little hassle as possible. Think Bluetooth, but using WiFi. Yes, the range’s gone so big, you can still transfer your MP3 while you go to poo.
Another thing, “most” products certified will also support “one-to-many” connections, enabling a Wi-Fi Direct laptop to be in contact with a printer, connected HDTV and a tablet simultaneously, with no router in-between at any point. Something important to note here, is that while 802.11a/g/n is supported over 2.4GHz and 5GHz bands, there’s no requirement for Wi-Fi Direct products to support 802.11b. Odd right?
Hardware wise, there’s no minimum requirement. That means any existing WiFi chipset could be upgraded via firmware to handle Wi-Fi Direct. Finally, they noted that the app ecosystem is likely to make this whole rollout a lot more interesting, particularly considering that Direct is simply a pipe that software can dictate as it sees fit. Don’t have to stick to your mate anymore when transferring that MP3.
