Dependence of Transfer Time of Bluetooth Payload Packets on the Surroundings and Distance

Abstract. This paper deals with the Bluetooth tech-nology in telecommunication networks. The basis for the data transmission is a packet which has its own specifics in the wireless communication. The signal level is of higher importance, but other parameters like transfer time and a number of transferred packets are interesting too. The output of this paper is a proposed mathematical model, which describes dependencies of this output parameters on the distance between com-municating devices and on the environment, in which these devices are placed. Some input criteria and con-ditions are defined for the functionality of the proposed design. The file transfer speed between the devices de-pends on the distance between them and on the sur-roundings, where the slave device is placed. For our purposes some possible surroundings that might be en-countered were selected. It is free-space, paper with variable thickness, PVC or leather and wood with their respective density. Thanks to the application of the log-arithmic regression on the output data the equation of mathematical model was found
