Biomedical data transmission with wireless communication: A review

Download this article as: 

Wireless biomedical sensing is a technique that measures physiological signals of humans or animals from a distance without a wire connection. Its basic components are sensor/transducer, transmitter, and receiver with a radio frequency wave as the most widely adopted transmission medium. The theory of wireless communication with an enhanced biomedical aspect is presented. The current status and future trends of this field are also discussed. In this a paper different manner of wireless monitoring of biomedical data are present. System is based on wearable sensor devices using wireless data transfer to send measured biomedical parameters to a central computer/server at hospital. The remote biomedical measurement system consists of several subsystems like biomedical monitoring sensors, wireless transfer of measured data, slave module, master module, central data base system and appropriate applications and automatic analyze, user interface software module and very important, hardware protected access realized by smart card. This system is suitable for continuous patients monitoring and gives possibilities to increase health care and safety of life.
