Bluetooth wireless technology is the low-power, short-range radio technology that allows electronic devices such as mobile phones, headsets, PDA's and notebook PC's to speak to each other without wires. Bluetooth is the established short range wireless technology.
Bluetooth wireless technology's Adaptive Frequency Hopping (AFH) capability was explicitly designed to reduce interference between wireless technologies sharing the 2.4 GHz spectrum. AFH works within the spectrum to take advantage of the available frequency. This is done by detecting other devices in the spectrum and avoiding the frequencies they are using. This 'adaptive hopping' allows for more efficient transmission within the spectrum, thereby providing the user with greater performance, even if using other technologies along with the Bluetooth wireless technology.
