“…Several companies/institution that developing VLC technology are: Nakagawa Laboratories (Japan) [1], Disney research (Switzerland) [2], pureLifi Ltd (UK) [3], IMDEA Network Institute (Spain) [4], and many more. Besides that, many universities also provide laboratorium access for VLC technology research, for example: Institut Teknologi Bandung (Indonesia) with research [5][6][7][8][9][10][11][12][13][14][15][16][17], Pukyong National University (South Korea) with research [18][19], Edinburgh University (Scotland) with research [20][21], National University of Singapore (Singapore) collaboration with Nanjing University (China) with research [22], Chulalongkorn University, Thailand [23], Kookmin university (South Korea) with KUET (Bangladesh) [24], etc.…”

To design Visible Light Communication (VLC) system, there are several requirements that needs to be met. One of the requirements is an active component selection (e.g. Op Amp). As an ideal communication system, VLC system has to be able to provides wide bandwidth access with minimum noise. The Transimpedance amplifiers (TIAs) is one of main components in optical system which is placed in the first stage of receiver system. It is used to convert the current output from photodiode to voltage. We have designed a 1 MHz fGBW TIA with low noise (in µVrms range). This paper aims to explain the design and implementation of TIA circuit with photovoltaic topology which cover empirical calculations and simulation of TIA's bandwidth and its noise sources, i.e. resistor feedback noise, current noise, voltage noise and total noise based on RSS. The OP-AMP is chosen from Texas Instruments product, OPA 380, and photodiode is chosen from OSRAM, SFH213, then simulated by TINA-TI SPICE® software. The noise in TIA circuit is analyzed clearly. The developed kit is ready to be implemented in VLC system.

“…In [ 30 , 31 , 32 ], VLC system designs for portable patient monitoring devices are presented; it is a two-way communication system, where downlink communication uses VLC, while uplink communication uses infrared. In [ 33 ] an integrated system is proposed through Power Line Communications (PLC) and VLC with Orthogonal Frequency Division Modulation (OFDM) for indoor hospital applications.…”

This paper proposes a new system based on the Industrial Internet of Things (IIoT) for the monitoring of Mobile Health (m-Health) of workers in the underground mining industry. The proposed architecture uses a hybrid model in data transmission. Visible Light Communication (VLC) is used for downlink because of its narrow coverage, which aids in worker positioning. Radio frequency (RF) communication technology is used to send data for primary vital signs in the uplink, which is more efficient in transmission and is a viable solution according to the problem raised. The results obtained in terms of coverage and transmission for the downlink and uplink links show the feasibility of implementing the proposed system.

“…As most of medical equipment are connected by cables for power and network communication in a local area network (LAN), their transportation between two locations can contribute to the spread of bacteria and/or viruses. Nonetheless, research related to transmission of patients' vital signal by VLC in hospitals is relatively sparse [15], although VLC is also used as a patient-monitoring wearable device [16]. For instance, in [17] a wearable VLC device was applied on a patient-monitoring system, which used a 30 cm optical link to transmit electrocardiogram (ECG) signals from the patient in addition to on-off-keying (OOK) modulation.…”

A Manchester-OOK Visible Light Communication System for Patient Monitoring in Intensive Care Units

Visible light communication (VLC) is an interesting solution in intensive care (IC) medical environments to, among others, prevent the spread of emerging diseases. This work presents the design of a low-cost and stable VLC transceiver system in addition to practical characterizations and experimental performance evaluations for application in IC environments. The application focuses on the transmission of Manchester-based on-off keying signals, in a proof-of-concept apparatus that makes use of the eye opening penalty (EOP) metric to illustrate a comprehensive picture of the potentials of the evaluated VLC system. Parameters such as light-emitting diode (LED) bias current, modulation frequency, line-of-sight link distance, and signal pattern were analyzed here. Experimental results show an outstanding behavior considering an LED bias current of 400 mA, a signal frequency of 1 MHz and a VLC transmission link length of 2.5 m. To validate our system, vital parameters as heart rate, oxygen saturation, pulse rate, respiration rate, temperature and non-intrusive blood pressure signals were transmitted for VLC links of 1.5, 5 and 15 m, which were received by a multi-parameter monitor, with EOP values of 0.89, 0.96 and 2.67 dB, respectively.
