Achievable rate regions for Bluetooth piconets in fading channels

We investigate the stability of a Bluetooth piconet operating in fading (Rice, Rayleigh or Nakagami) channels. By taking into account many protocol details, such as modulation scheme and packet formats, we provide an analytical characterization of the achievable rate regions, which, for a network of N nodes, turns out to be the interior of a convex polyhedron in a (2N-2)-dimensional space. We show also that some previous analysis of Bluetooth link performance, by neglecting the impact of the multiple access scheme, may lead to erroneous conclusions in terms of optimal packet format.
