I wonder how it differs from the existing WiFi P2P protocols. Perhaps it won't depend on IPv4? Perhaps it will be nonroutable?
I also wonder if "they" will make a low power WiFi chipset suitable for "normal" phones?

The trade-off for this is a larger power draw.

I've never had a WiFi enabled phone, but the entire design logic behind BlueTooth was low power consumption for portable devices to communicate over short distances. WiFi is a lot more thirsty, and designed for much greater range.

I have to say, I wouldn't be particularly sad to see the death of the current BT standard. It's just so damned slow. However, I always imagined something like "wireless USB" or the UWB BT 4.0 would replace it.

I must admit, it sounds a lot like the ad-hoc which wireless has been able to do since its inception... :?

And yes, it needs to lower power consumption, not increase it, if it is going to replace ad-hoc networks or Bluetooth... :?

Suits me. I've never used Bluetooth as nothing apart from my phone supports it.

The only time I've used BT is between mobile phones. With my laptop, I used the memory card directly (much easier than faffing around with the USB cable).

I'm sure there's a way to create an ad-hoc connection using the iphone and my lappy. Anybody know a good method/app for this?

I use BT between my phone and my comp (new phone means I've lost the remote control facility of my old Sony :( ), and with my hands free in the car.
I like it.

It is good news but it won't kill bluetooth.

Bluetooth is great for things like hands free and basic home use, such as PS3 controllers and speakers. This form of wifi will be great for anything internet enabled, everything else will carry on using good ole low-powered bluetooth. There's room for both.

I'm not sure if that's what it's aimed at. As I said earlier, I'm not sure if this is even going to be a routable protocol. There simply is not enough information in the article to know what it's good for!

The release of Wi-Fi Direct is expected to pose a direct threat to Bluetooth which has long been the common standard for peer-to-peer filesharing between mobile devices.

The suggestion is that it will not be used for Internet, but instead as a substitute for Bluetooth for file transfers.
