Bluetooth 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.
Features of Bluetooth technology
. Bluetooth technology uses radio waves for communication in 2.4 GHz
. It supports multipoint 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.
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 band. Bluetooth technology is a free of charge service but your mobile phones set should support the GSM and CDMA technology.
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.
