Can Bluetooth do directional transmission like infrared rays? Could anyone provide me some brief knowledge for wireless directional transmission (ex: laser, bluetooth, infrareed...) . I am really interesting about how it works, how small the equipment can be, and what the price (ex: from newspaper, I remember current market price for bluetooth chip is $5 each)?
