Bluetooth is well known digital wireless communications system intended to replace the cables connecting mobile or fixed electronic devices over short distances (up to ten meters). Bluetooth is commonly integrated into cellphones (for bluetooth hands-free headset for example) or in laptop (bluetooth mouse&keyboard,...). All the bluetooth devices emit data in the 2.45 GHz ISM band. As a result, mutual interference is a potential problem for bluetooth applications.

The development of this technology has been really fast during the past years and now bluetooth devices are spread everywhere in cities. According to the density of the population and the power of the bluetooth emitter, it is possible to have scenarios where the number of interferences becomes some high that nodes can no communicate together anymore. But evaluate those scenarios is not trivial, because the probability of interferences depends on multiple parameters.

At the RCS, we work on mathematical frameworks and simulation tools to analyze the risk of interferences in Body Sensor systems (using bluetooth protocol)  and try to find solution to improve the communication efficiency.
