What is Bluetooth Technology?

Bluetooth technology is a type of the wireless technology that eliminates the need for the number of inconvenient cables and devices that are used to connect the computers, mobile phones, digital cameras, handheld devices and new digital appliances. Bluetooth enables the users to connect to a wide variety of telecommunication and computing devices easily, without cables.

It makes rapid ad hoc connections, automatic unconscious connections between two or more digital devices. Bluetooth provides the opportunity of using the mobile data in different applications. Bluetooth makes wireless communication between the two devices in a localized area of a room of office or home very easily. Bluetooth technology uses radio-based links and all the connections between the devices and invisible and instantaneous.

By Bluetooth technology your laptop can send print request to a printer in your next room. Bluetooth is actually a standard for wireless communication between the devices in a relatively small area and it is therefore works fine in the personal area network (pan) using radio frequency.

Any two devices that follow the Bluetooth standard can communicate with each other. A number of the Bluetooth devices like digital camera, mobile phone and handheld pc can form a network. You can send emails to your mobile phones from your laptop without any physical connect between your laptop and your mobile phones.

Features of Bluetooth technology

? Bluetooth technology uses radio waves for communication in 2.4 GHz
? It supports multi point communication not just point to point.
? Bluetooth works in a small area of 10-15 meters.
? Bluetooth offers speed of 1-2 mbps.
? Bluetooth chipsets are less expensive though more expensive than IrDA.

How Bluetooth technology works

Bluetooth is a high speed wireless link technology that uses the radio waves. It is designed to connect the mobile phones, laptops, hand held devices and portable equipments with almost no work by the end users. Unlike infrared Bluetooth does not require line of sight between the connecting units. Bluetooth technology is a modified form of the current wireless LAN technology and it?s more acceptable for its relative small size and low cost.

The current circuits are contained on a circuit board of 0.9 cm square and a much smaller single chip version is in development and soon it will be in use. The cost of the Bluetooth device is expected to fall rapidly. Bluetooth chip has to be equipped in many devices. In Bluetooth technology, small and inexpensive transceivers have been placed in the digital devices. The radio waves operate at 2.45 GHZ band on the Bluetooth devices. Bluetooth supports the data speed up to 721 Kbps and 3 voice channels. The Bluetooth chip can either be built into the devices or it can be uses as an adapter. In computer it can be used with the USB port. Each Bluetooth device has a 48 bit address from the IEEE 802 standards and the Bluetooth connections can be either point to point or multi point. Bluetooth range is 10 meter but it can be extended up to 100 meters by increasing the power.

Bluetooth devices are protected from the external interference because they change their frequency up to 1600 times in a second. Bluetooth radio technology provides the bridge between the existing data network. Bluetooth guarantees security at the bit level and the authentication is controlled by the end user by using 128 bit key. An important face of the Bluetooth technology is that it instantly forms a network when two or more devices come closer in the range of each other.

Bluetooth technology benefits

Bluetooth technology is a convenient choice of communication in a wire free, short range environment. Bluetooth is a globally available standard for connecting the devices like mobile phones, digital cameras, laptops, mp3 players, cars, stereo headsets etc. Bluetooth enable devices do not need to install any drivers. The key benefits of the Bluetooth wireless technology are its built-in-security, low cost, easy of use, robustness, and ad hoc networking capabilities.

The Bluetooth wireless technology is available globally. Many manufactures from the different companies are busy to implement the technology in their products. Bluetooth technology operates in the 2.4 GHZ, one of the unlicensed, industrial and scientific radio bands. Bluetooth technology is a free of charge service but your mobile phones set should support the GSM and CDMA technology.

Today mobile phones have built in capabilities and Bluetooth functionalities in them. Bluetooth technology is available in the different range of the devices like mobile phones, automobiles, medical devices, industries and enterprises etc. Due to the key features of the Bluetooth technology like low power consumption, low cost and wireless features make it more popular. Bluetooth technology does not require any fixed infrastructure and it is very simple to install and setup.

No wires are required to connect the Bluetooth devices. You can connect to other Bluetooth enabled devices anytime if they come in your range. Bluetooth wireless technology is widely supported and is secure wireless standard today. Bluetooth devices has built-in security features such as 128 bit encryption and pin code authentication when Bluetooth devices identify themselves they use the pin code when they first time connect.

What Is Bluetooth - A World Without Wires

Bluetooth technology was created in order to allow ordinary technology users to enjoy the benefits of low bandwidth wireless connections. Bluetooth is a low power, short-range technology that allows wireless networking. It is able to do this by using radio waves to send and receive data at up to 720 kilobits per second.

Bluetooth Specs

The specifications for Bluetooth devices allows for different classes of radio transmission ranges. These ranges can reach up to about 300 feet by boosting the radio power. This technology isn't limited to line of sight as the waves it utilizes are directional waves, which are capable of transmitting through various obstructions.

Industry Standard

Bluetooth is quickly becoming the standard as far as wireless communication is concerned. The real beauty of Bluetooth is the fact that it goes far beyond the most commonly recognized uses and connects all manner of devices. Not only cell phones, but also computers, digital cameras, PDAs, laptops, and any number of other digital devices. The specifications for Bluetooth are defined as a radio system that has a 'stack' of protocols, layers, and profiles. The highest layer is the actual application with lower layer being the radio.

Wireless technology such as that offered by Bluetooth is in a position to completely revolutionize our ability to be connected and share information by allowing us to go wireless and eliminating the need for strings.

Bluetooth eliminates the need for cables and wires while providing connectivity on a level we've never experienced before. This low cost solution links computers, cell phones, and any manner of other Bluetooth enabled devices quickly and easily.

Bluetooth is also a sturdy link, which will allow you to go about business as usual rather than worry that a connection is going to be impaired because of its wireless nature. Bluetooth has shown none of the ordinary weaknesses of other wireless devices to interference and constant interruption by other devices operating on the same frequencies.

Another benefit to Bluetooth is that it operates at a frequency of 2.4 GHz, which allows it to be license free and widely available throughout the world. No matter where you are, it is quite likely that your Bluetooth device will work.

Security is another matter that is often weak with electronic devices, particularly those with wireless connections. Bluetooth offers advanced mechanisms to ensure your security and that of your information. It is very difficult for your data to be compromised or your conversations heard with Bluetooth.

Another great feature of Bluetooth is its ability to optimize its power consumption. The radio feature is very power friendly and the device itself only consumes a minimal amount of power that it 'borrows' from a cell phone.
