An independent study confirms that Bluetooth awareness are rising across the globe. I have always been a proponent to Bluetooth technology ever since I got one of Ericsson's last mobile phones the T39m which was one of the first product to have the technology built-in.
Bluetooth, which was originally developed by Ericsson, is very easy to use and maintain reliable connection if used within its range. Some have pronounced Bluetooth dead in the wake of WiFi's booming industry but in my view both are very different technologies. While WiFi is just a wireless extension of ethernet connection, Bluetooth with its low battery usage is more practical.
The imminent arrival of Bluetooth 2.0 with faster speed will only help spread the technology.
