Bluetooth Wireless Networking




Bluetooth technology offers three different types



of defined ranges, based on output ranges. Class



1 devices are the most powerful, as they can have



up to 100 mW of power, with a regular antenna



giving them a range of around 130 - 330 feet.





The class 2 devices are lower power, offering up



to 2.5 mW of power. A regular antenna will give



them a range of around 50 - 100 feet. Class 3



devices use even less power, up to 1 mW of power



to be exact. With a regular antenna, they will



have a range of around 16 - 33 feet.





Even though you may not realize it, Bluetooth



wireless technology has never been intended for



anything other than short distance types of



communication. With Bluetooth wireless, the short



range is actually a benefit.





For one, the short range will reduce the change of



interference between your devices and those that



belong to others who are nearby. Overall, this



is a basic type of security, designed to protect



you and your devices.





Secondly, the lower power used for short range



means a longer battery life. Most Bluetooth



devices will get their power from a battery,



meaning that anything you can do to lengthen the



battery life is very important.





The wireless networking offered by Bluetooth is



actually among the best, even though it uses



short range communication. Bluetooth is used



with wireless controllers, the internet, and



even wireless headsets.





For the best in short range technology, Bluetooth



is extremely hard to beat. If you've never tried



Bluetooth before, now is the time. It's the best



with wireless networking, especially for those



who enjoy hands free talking on their cell phone.
