This week I hope to explain the differences between the two.
First, let us take a look at Bluetooth.
Bluetooth was designed to allow low bandwidth wireless connections to become easy to use so even those who are new to wireless can use them.�
The idea is that you can link devices together with Bluetooth rather than use cables but is not normally used for linking directly to the internet.
Practical experience tells me that maybe the stated objectives of Bluetooth don�t always match reality.
Version 1 of� Bluetooth describes a low power, short range wireless
networking technology that uses radio waves to send data at rates up to 720 kilobits a second.

The specification for Bluetooth allows for different classes of radio that allow transmission ranges of up to 100 meters by boosting the radio power. The
technology of Bluetooth isn't limited to line of sight transmission since it uses directional waves that are capable of transmitting through many
obstructions.

Bluetooth is an industry standard communication of wireless, meaning that it enables the connection of other devices as well, such as cell phones,
computers, digital cameras, & other types of electronic devices. The specification of Bluetooth defines a radio system and a "stack" of protocol
layers and profiles. The highest layer is the application layer, while the lowest layer is the radio.

The wireless technology of Bluetooth is positioned to revolutionize the personal connectivity market by providing freedom from inconvenient fixed type lines.

The specification for Bluetooth eliminates the need for cables by providing a small form factor, low cost wireless solution that will link computers,
cell phones, and other electronics. Bluetooth also allows users to connect many ranges of devices fast and easily and expands communications
capabilities as well.

The size of the Bluetooth radio is remarkable, as a Bluetooth radio can be built into one or two very small microchips then integrated into any electronic
device where wireless operations would be an advantage.

Bluetooth also offers a robust link, which ensures that normal operating circumstances are not interrupted by interference from other signals
that are operating in the same frequency band.

Also known for its worldwide operation, Bluetooth radio operates in the 2.four GHz frequency band, which is license free and reachable to any type of
radio system in the world. No matter where you are in the world, you count on Bluetooth to work.

Security is also important. Offering advanced security mechanisms, Bluetooth ensures a high level of security. Therefore, authentication will prevent unauthorized access to important data and make it very difficult to listen in.

Bluetooth also boasts power optimization. The radio is power friendly and the software for Bluetooth is very configurable, limiting the power consumption
of equipment. The radio itself only consumes a small amount of power from a cellular phone.

In reality, Bluetooth can be problematical to get working. If you install it and configure it and manage to get it working with various default settings great. For example, I have a Bluetooth headset for my mobile phone that I use when driving. This installs fine and works really well. However we have found that configuring something like say a Nokia phone to act as a GPRS modem linking to a PC using Bluetooth is almost a black art and I would be surprised if the majority of ordinary end users could achieve this.
SO, it may be a bit fiddly, but it is a useful technology. Even if your existing laptop or desktop PC does not have Bluetooth you can get a USB Bluetooth dongle that will work just fine for just a few hundred Baht. Call in at the office for more details.
