What is Bluetooth Mobile Wireless Technology
With every passing month, it seems that more electronic devices are touted as being Bluetooth enabled. And,
while many people are excited about the advent of new Bluetooth products, others are left scratching their heads
wondering, what is Bluetooth? Bluetooth mobile wireless technology has become one of the leading technologies for
wireless communication world wide.
The reason it has become so popular around the globe, in just a few short years since its introduction, is
because Bluetooth technology allows phones, computers, PDAs and other electronic devices to easily communicate with
the other Bluetooth enabled devices nearby. The range of Bluetooth wireless technology networking is limited to a
short range of about 30 feet.
Bluetooth utilizes radio waves, in the non-licensed range of 2.4 Gigahertz. The Bluetooth wireless system has
been designed with the intention of providing a secure and an inexpensive way to connect with and exchange
information between other Bluetooth devices, all without the need of wires.
What is Bluetooth used for? The Bluetooth technology is now found in most of the newest models of cellular
phones, virtually all handheld computers and PDAs, many models of laptop computers, some models of printers and
virtually all types of wireless cell phone headsets. These are just a few of the current electronic devices that
incorporate the technology and more products are being introduced all the time.
In addition to the Bluetooth wireless phone models, which are probably the most prevalent type of Bluetooth
devices on the market, you can now also find Bluetooth wireless headphones and Bluetooth wireless speakers. It is
expected that other Bluetooth wireless audio and video products will continue to be brought to the marketplace.
With this type of advancement, it is conceivable that some day the only wires you will need to tame, will be the
power cords that some of these devices will need for their power supply. That would be a welcomed change from the
tangles of cords and wires that are common in home offices and entertainment areas.
One of the best features, is that all Bluetooth enabled devices function on a standard protocol. This means that
all transmission of data and voice signals between two Bluetooth devices, even if they are produced by different
manufacturers, is straightforward and simple to implement.
It was the need for a standardized communication convention that prompted the development of Bluetooth
technology. Rather than the need for each manufacturer to establish their own standards, and thereby limit the
connectivity to other devices made by the same company, they can simply implement the Bluetooth wireless technology
networking standard. This simple approach has made Bluetooth a global solution used by all manufacturers and
benefiting the end-user significantly.
Some of the other advantages of Bluetooth are: data transfers that are fast; communication with other Bluetooth
devices that are not in a direct line of sight (as required by the infra-red protocol); inexpensive circuitry and
components; the ability to transmit both data and voice concurrently.
This technology has been on the market for almost a decade. One of the reasons it is relatively inexpensive and
widely used is because the original developer, Ericsson, has made the specifications royalty-free so manufacturers
do not have to pay to implement the technology in their devices. Because of this, the use of Bluetooth technology
is expected to expand and soon no one will be left asking the question, "What is Bluetooth?"
