Bluetooth is a network technology that connects mobile devices wirelessly over a short-range to form a personal area network (PAN). They use short-wavelength, ultra-high frequency (UHF) radio waves within the range 2.400 to 2.485 GHz, instead of RS-232 data cables of wired PANs.
Features of Bluetooth
Bluetooth technology was released in 1999 as Bluetooth 1.0, by Special Interest Group (SIG) who continues to manage it.
It was initially standardized as IEEE 802.15.1.
Mobile computing devices and accessories are connected wirelessly by Bluetooth using short-range, low-power, inexpensive radios.
UHF radio waves within the range of 2.400 to 2.485 GHz are using for data communications.
A PAN or a piconet can be created by Bluetooth within a 10 m radius.
Presently, 2 to 8 devices may be connected.
Bluetooth protocols allow devices within the range to find Bluetooth devices and connect with them. This is called pairing. Once, the devices are paired, they can transfer data securely.
Bluetooth has lower power consumption and lower implementation costs than Wi-Fi. However, the range and transmission speeds are typically lower than Wi-Fi.
The lower power requirements make it less susceptible to interference with other wireless devices in the same 2.4GHz bandwidth.
Bluetooth version 3.0 and higher versions can deliver a data rate of 24 Mbps.
The Bluetooth version 4.0 came in 2010. It is characterized by low energy consumption, multivendor interoperability, the economy of implementation, and greater range.
