The paper aims to present the organizational concept of the wireless personal area network (WPAN network) transmitting biomedical data, used in the BioSip system. The network transmits data from recording modules arranged on the subject's body to a collective node (data integrator). At the same time, all the necessary properties are maintained, i.e. low power consumption of the modules, increased resistance of the network to artefacts, the required transmission speed and signal delays. The options to synchronize measurements in various modules have also been presented, along with the resulting benefits. The wireless personal area network of BioSip modules may be based on various communication protocols, such as Bluetooth Smart or ANT. The BioSip network builds on its own protocol based on transmission mechanisms by Nordic. The software of BioSip modules may be adapted for operation in the Internet of Things through network protocol layers made available by Nordic.

This paper presents a new technique of reduction retransmission time by decreasing the discarded packets and combating the complexity through error control techniques. The work is based on Bluetooth, one of the most common Wireless Personal Area Network. Its early versions employ an expurgated Hamming code for error correction. In this paper, a new packet format using different error correction coding scheme and new formats for the EDR Bluetooth packets are presented. A study for the Packet Error Probability of classic and Enhanced Data Rate (EDR) packets is also presented to indicate the performance. The simulation experiments are performed over Additive White Gaussian Noise (AWGN) and Rayleigh flat-fading channels. The experimental results reveal that the proposed coding scheme for EDR packets enhances the power efficiency of the Bluetooth system and reduce the losses of EDR packets.
