| Features of Bluetooth technology | | | | |
| | | | The Bluetooth wireless technology is |
| • Bluetooth technology uses radio waves | | | | available globally. Many manufactures from |
| for communication in 2.4 GHz | | | | the different companies are busy to implement |
| | | | the technology in their products. Bluetooth |
| • It supports multipoint communication | | | | technology operates in the 2.4 Ghz, one of |
| not just point to point. | | | | the unlicensed, industrial and scientific |
| | | | radio band. Bluetooth technology is a free |
| • Bluetooth works in a small area of | | | | of charge service but your mobile phones set |
| 10-15 meters. | | | | should support the GSM and CDMA technology. |
| | | | |
| • Bluetooth offers speed of 1-2 Mbps. | | | | Today mobile phones have built in |
| | | | capabilities and Bluetooth functionalities in |
| • Bluetooth chipsets are less expensive | | | | them. Bluetooth technology is available in |
| though more expensive than IrDA. | | | | the different range of the devices like |
| | | | mobile phones, automobiles, medical devices, |
| How Bluetooth Technology Works | | | | industries and enterprises etc. |
| | | | |
| Bluetooth is a high speed wireless link | | | | Due to the key features of the Bluetooth |
| technology that uses the radio waves. It is | | | | technology like low power consumption, low |
| designed to connect the mobile phones, | | | | cost and wireless features make it more |
| laptops, hand held devices and portable | | | | popular. Bluetooth technology does not |
| equipments with almost no work by the end | | | | require any fixed infrastructure and it is |
| users. Unlike infrared Bluetooth does not | | | | very simple to install and setup. |
| require line of sight between the connecting | | | | |
| units. Bluetooth technology is a modified | | | | No wires are required to connect the |
| form of the current Wireless LAN technology | | | | Bluetooth devices. You can connect to other |
