Bluetooth Phones Technology
Bluetooth technology is only been around for the last couple of years. So it’s relatively new. However, the usage of bluetooth technology in cell phones industry has quickly exploded because of its advantages.
The name “Bluetooth” comes from a name of 10th-century Danish king, Harald I Blatand, or Harald Bluetooth in English (born c.935). He was well known as a great king who unified Denmark, Sweden and Norway, just like bluetooth technology is designed to allow collaboration between various industries such as cell phones, computer and automotive markets. The word bluetooth in his name could indicate that Harald had a “blue” or dark tooth that might be from an accident. The other legend says that he had an affinity for teeth-staining blueberries.
Basically, background of bluetooth technology development was creating a single digital wireless protocol that was capable of connecting multiple devices and overcoming issues arising from the synchronization of those devices. Bluetooth phones adopt one of the most secure wireless standards on the market. Its power conservation, security, and connectivity are unmatched, although it’s useful mostly across only in short distances. Bluetooth phones are more popular than infrared phones because bluetooth phones have wider coverage range than infrared phone. Bluetooth phones even can be utilized to send and receive data from one room to another within a range of 20 meters crossing all barriers.

The bluetooth system in bluetooth phones works upon a power efficient radio chip, which is small enough to fit inside any mobile phones. Most of the bluetooth phones are “class 2″ bluetooth. It means that the bluetooth coverage is up to 30 feet (10 meters). The other class is the “class 1″ bluetooth phones, which have up to 300 feet coverage area. Bluetooth phones can make up to seven connections at one time, at a speed of 1Mbps.
Bluetooth phones networking transmit data via low-power radio waves, and communicate on a frequency of 2.45 gigahertz. This frequency band has been set aside by international agreement for the use of industrial, scientific and medical devices (ISM). A number of devices use this same radio-frequency band. Garage door controllers, baby monitors and the newest generation of cordless phones all make use of frequencies in the ISM band. Making sure that a Bluetooth phones and those other devices don’t interfere with one another has been a crucial part of the design process.
As happen with any other wireless device, a bluetooth phones have some minor security concerns. The well known security issues are:
- Bluebugging; hacker secretly accesses a bluetooth phones command, such as eavesdropping on conversations
- Bluesnarfing; hacker secretly accesses a bluetooth phones data, such as phone contacts or short message
- Bluejacking; hacker creating a flirtatious introductory message, then sending it as a text message to nearby bluetooth phones that is discoverable.
To make your bluetooth phones more secure, you can lock your bluetooth phones with a special code or simply turned off or put in hidden mode when bluetooth service is not in use.
The relatively low cost of bluetooth phones make it more appealing. Some bluetooth phones are even less expensive than a phone without that facility. In today’s technology, cell phones have more become a necessity than a luxury. With the invention of bluetooth technology, the use of mobile phones has become more convenient and practical.
