If there's a must-have mobile technology this year, that's Bluetooth over Wi-Fi. Easy-to-establish, peer-to-peer Bluetooth connectivity seamlessly coupled with Wi-Fi speeds. As the video shows, the experience is perfect. I want this in my iPhone.
The new Bluetooth specification—technically denominated alternate MAC/PHY—will be official this April. And unlike other technologies, it won't be in limbo for a while before reaching consumers. In fact, your phone may support it right now, according to Broadcom's Mukul Suth: Some of their current production chips already have this ability and they will only require a software upgrade to implement it.
The alternate MAC/PHY method is quite clever: The two devices discover each other and shake hands using Bluetooth (being mobile phones, computers, or any other shiny thing supporting the standard). When you start any file transfer, the communication gets passed to the Wi-Fi hardware layer, which will transfer your data at 54mbps. Once the transfer is over, Wi-Fi is disconnected and the control passes again to Bluetooth.
It just works. According to the Bluetooth Special Interest Group, the standard will allow you to easily:
• Wirelessly bulk synchronise music libraries between PC and MP3 player
• Bulk download photos to a printer or PC
• Send video files from camera or phone to computer or television.
Sounds good to me. Having this easy-to-use, straightforward ability to just connect to any device and transfer information in a fast way, without needing any wireless network or access points, will be great.
