Organization of fast biomedical data transmission in a low-power, high-reliability wireless personal area network (WPAN) dedicated to data acquisition from BioSip modules

The article is aimed at presenting 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 attached to various locations on the subject's body to a collective node (data integrator) while maintaining all the necessary properties, such as low power consumption of the modules, increased resistance of the network to artefacts, the required transmission speed and signal delays. WPAN networks are based on various communication protocols, such as ZigBee, Bluetooth, ANT. In BioSip, the network uses its own protocol based on transmission mechanisms of the systems made by Nordic.
