To improve performance in these environments, a technique known as Adaptive Frequency Hopping has been introduced by the Bluetooth Special Interest Group (SIG) to diminish the impact of such interference. Also referred to as AFH, this technique can be implemented through various methods, each with its own inherent set of advantages and drawbacks. Ericsson, a leader in the field of Bluetooth wireless technology, uses a method well suited for its broad based Bluetooth design solution sold as intellectual property (IP). Ericsson's implementation of AFH is further enhanced through the use of other standard and proprietary techniques, providing excellent audio quality for voice centric applications in the presence of multiple wireless technologies.
