How Bluetooth 4.0 will change your life.

Wireless technologies have been transforming domestic life since the availability of home radios in the 1920s. Since then every new kind of wireless technology and every new application has brought more transformative changes to the home. 

Television, for example, used to receive its signal wirelessly, which enabled its fast adoption in the 1950s. As the use of cable TV spread, transforming a wireless signal into a nonwireless one, wireless remote controls added another convenience. 

Cordless phones changed when and where you could make and receive calls. Wireless garage door openers and other special-purpose wireless devices subtly improved people's lives in small ways. You probably have a Wi-Fi network in your home, which you use to connect computers, laptops, phones and possibly your TV to the Internet. 

You probably also use another wireless technology called Bluetooth. If you have a wireless headset with your cell phone, or a wireless keyboard or mouse with your computer, you're using Bluetooth. 

Both Wi-Fi and Bluetooth are geeky technologies working invisibly and behind the scenes to subtly and profoundly change homes all over the world. They've eliminated cables, reducing clutter. And they've freed you to place consumer electronics devices anywhere. 

Here's how Bluetooth 4.0 is going to change your life:
