Today’s Eio post is on Bluetooth® technology.
What is Bluetooth®?
Bluetooth®, a name for the wireless technology standard, exchanges data over short distances in order to eliminate the need for cables. Bluetooth® devices work by connecting two or more pieces of electronic equipment to exchange information via short wavelength radio signals. The distance is usually around 33 feet (or 10 meters).
Bluetooth exists in numerous electronic devices, from the iPod touch, to the Playstation 3, to headsets, to cell phones, even to watches. Most modern day laptops have integrated Bluetooth technology so that keyboards and mice can be hooked up without any plugs or cables.
Its technology is ideal when transfering information between devices in low-bandwidth situations, for example, the sound from a cell phone to a Bluetooth headset.
Wisegeek.com states that there are three classes of Bluetooth strength. “The maximum bandwidth for any single channel or frequency is 1 megabyte per second (1Mbps), while individual packets range up to 2,745 bits. There are currently three flavors or classifications of Bluetooth® devices, relative to transmitting range. As the range is increased the signal used in the respective classification is also stronger. Note that Class 3 devices are comparatively rare.”
|Class 1||1 milliwatt||Up to 33 feet (10 meters)|
|Class 2||10 milliwatts||Up to 33 feet (10 meters)|
|Class 3||100 milliwatts||Up to 328 feet (100 meters)|
