"The spec also includes a new feature which will prevent annoying dropped connections when a device is put into a pocket or bag."

So hang on, they've figured out a way to fix the age old problem of radiowaves transferring through the incredibly dense material known as clothing.

/sarcasm

question: So can i still use my Wifi & transfer a file via bluetooth at the same time ? Or will I now have to disconnect from wireless LAN first to do bluetooth.

Well, every transfer is done in seconds. It just depends on how many seconds... :)

So, it can transmit at speeds approaching conventional WiFi.........over Wifi. Genius!

Joking apart though, I'm all for device convergence and ease of use, and this is another step along the road.

Considering most bluetooth controllers are now integrated into the same silicon as the wifi, this makes sense, especially if the bluetooth+wifi stack automatically sets up the peer-to-peer wifi network for the file transfer without any faff (as it sounds like). How much of this is software (potentially at the hardware firmware level than the OS level) and how much is hardware?
