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.
