Bluetooth wireless technology is a short-range communications technology intended to replace the cables connecting portable and/or fixed devices while maintaining high levels of security. The key features of Bluetooth technology are robustness, low power, and low cost. The Bluetooth specification defines a uniform structure for a wide range of devices to connect and communicate with each other.
Bluetooth is a proprietary open wireless technology standard for exchanging data over short distances (using short length radio waves) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security. Invented by telecoms vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization. Today Bluetooth is managed by the Bluetooth Special Interest Group.
Range
Bluetooh is based on short radio transmissions and the regular range for the Bluetooth radius is 10 metres. Upgrade your equipment, however, and you can extend that tenfold into 100 metres, which is great for such a portable technology.Bandwidth
You can do more with your Bluetooth. The maximum data transfer rate (that is, how much information can be transmitted at once) is 724 kbits/s for a maximum of three voice channels (plus data.)Security Measures
Not one but two different security mechanisms have been implemented to ensure a high level of security:- Authentication - This prevents access to critical data and makes it impossible to falsify the origin of any message.
- Encryption - This prevents anyone from eavesdropping on you and maintain the privacy of the link.
