Bluetooth Technology
With no physical connection required, the Bluetooth Special Interest Group (SIG) create wireless technology standards for hardware manufacturers to use when they create new devices. As technology evolves, wireless communications technology does, too. At the time of this writing, there are two Bluetooth technology standards that developers use to keep you connected. Although similar, there are subtle differences that make them useful for different applications. Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts , giving it a very short range of up to 10 metres (33 ft). It employs UHF radio waves in the ISM bands , from 2.402 GHz to 2.48 GHz. [3] It is mainly used as an alternative...
