Abstract Now a days, modern hospitals are adopting electronic health (E-Health) over traditional health care services. The E-Health services are provided by a radiation free, high capacity, high transmission rate and radiation free communication. In this paper, a hybrid radio frequency-wireless visible light communication (VLC-RF) system gives a newest solution to change the traditional wireless communication systems in health organizations. This paper provides an all-purpose system model where the biomedical information from patient are transmitted using VLC uplink to a decode and forward relay which further radiocasts that information to the laboratory. Finally a feasible demonstration which extracts the carotid signals data from patient is implemented in the laboratory.
1 Introduction Wireless technologies are used in medical area networks to increase flexibility and ease for medical staff and patient, but it has been reported that many frequencies of radio waves induce strong electric field intensity, which is prone to interfere with electronic medical equipments, which is a risk towards the accuracy of medical equipments [1]. This paper gives a inventive design and implementation of a medical healthcare data system using the rising wireless visible light communication (VLC) technology in combination with existing radio frequency communication network. The hybrid VLC-RF based medical healthcare system model can be used to give data services and keeping track of patients in radio frequency restricted health organization areas. This system delivers services such as telemedicine, client-patient portal, diagnostic reports, home care, E-medical documents, health database, old records management, etc. [2, 3]. Networks using VLC technology can be implemented using light emitting diodes (LED), to transmit medical and healthcare information [4]. In this paper, we propose a hybrid VLC-RF setup for the A.

hospital database management and applications in indoor environment. Hybrid VLC-RF setup implementation in the hospitals is a novel idea, which is demonstrated by transmitting real bio medial signals in the laboratory. In this paper we considered an radio frequency influenced environment in which EM waves cannot pass through the walls of the room to keep the indoor environment free from RF radiations [4]. Biomedical instruments generate signals which are received at a relay node and this node is incorporated with the optical transceiver. The relaying node decodes the signal and forward it to some distant Laboratory or research lab via RF link as shown in Fig. 1.
