“…It can be used for communication due its wide range, and is environmentally friendly [1][2][3]. VLC was introduced for ITS interaction to complement and commute the present radio frequency (RF) communication by solving the saturation problem in its band, considering each light source as a free access point [4].…”

“…In the meantime, the light-emitting diodes (LEDs) that have been widely deployed in traffic lights can be used as VLC transmitters because they are a possible energy-saving light source, with long life, small size, and low power consumption. Therefore, LEDs are used on different occasions, such as for traffic lights and street lighting that can be used for communication, so that large-scale power can be employed effectively and that could not be used for radio or infrared contact [4][5][6].…”

A comprehensive study of outdoor visible light communication (VLC) under snow and rain effects has been conducted in this paper. This paper analyzes the expected rain attenuation of Marshal, Carbonneau, and Japan models at different precipitation levels. Snow attenuation is measured in wet and dry situations at various precipitation levels as well. Therefore, a full comparison is carried out for different attenuation effects on certain outdoor VLC design characteristics such as the maximum signal-to-noise ratio (SNR), optical power received, bit error rate (BER), and maximum coverage area. VLC with various modulation techniques is considered. The ON–OFF Keying (OOK), L-Pulse Position Modulation (L-PPM), Inverse L-Pulse Position Modulation (I-L-PPM), and Subcarrier Binary Phase-Shift Keying (SC-BPSK) are investigated. The simulation results show a considerable difference in the information received under different weather conditions depending on the type of modulation scheme used. The simulation has been done on a two-lane road, and a green traffic light-emitting diode (LED) with a wavelength of 505 nm is used as a transmitter. A non-imaging concentrator coupled with a photodetector is considered to be a cost-effective receiver.

“…Teknologi ini memanfaatkan cahaya tampak dalam mentransmisikan datanya. Teknologi VLC memiliki banyak keunggulan dibandingkan komunikasi Radio Frequency (RF) diantaranya adalah aman dari interferensi gelombang elektromagnetika, lebih aman (secure) karena cahaya tidak dapat menembus penghalang, memiliki efisiensi energi yang tinggi dan biaya implementasi yang murah [1]- [5].…”

Abstrak -Penerapan visible light communication (VLC) berlandaskan pada pedoman IEEE 802.15.17 yang mana aturan tersebut baru dirancang dalam waktu 5 tahun belakangan ini (sejak tahun 2009), didalamnya meliputi standar layer fisik (physical layer) dan layer MAC (medium access control). Sebagaimana teknologi komunikasi pada umumnya, VLC juga menyediakan akses security yang dibahas pada bagian layer MAC. Namun pada praktiknya masih belum begitu masif dilakukan oleh para peneliti. Hal ini sangat wajar karena mengingat VLC merupakan teknologi yang sedang dalam tahap pengembangan, yang menjadikan penelitian VLC umumnya berfokus pada 'bagaimana meningkatkan speed dari keterbatasan komponen-komponen pembangun (IC, photodiode, LED, transistor) yang tersedia saat ini. Tantangan teknologi VLC selain target peningkatan kecepatan bit-rate, mobility communication, mengurangi interference noise, menyediakan layanan multi-acces juga salah satunya adalah isu security. Makalah ini merupakan studi literature (review paper) yang didapatkan dari dokumendokumen hasil peneltian baik di jurnal dan conference terkait dengan praktik-praktik security VLC yang pernah dilakukan dengan skema indoor maupun outdoor. Kata kunci -VLC, Security, Komunikasi dan Informasi, ReviewAbstract -Implementing VLC system is based on IEEE 802.15.17 standard where this guideline was designed within the past 5 years ago (since 2009), this guideline covers standard of physical layer (PHY) and medium access control layer (MAC). As communication technology in general, VLC provide security acces which discuss in MAC layer part. However in real practice, we found that they haven't been massively conducted by researchers in the world. The reality is very reasonable due to this technology is under development, it can make VLC studies commonly are focus on "how to increase the speed of VLC with limitations components which are available at this time (such as ICs, photodiodes, LEDs, transistors, etc.)". VLC technology challenges, not only 1) to increase the speed of bit-rate, 2) serve mobility communication, 3) reduce noise interference, 4) providing multi-service acces, but also how to implement security issues in VLC. This paper is a study of literature (review paper) which are obtained from the scientific documents from journals and conferences related to security practices VLC both for indoor and outdoor schemes. Haas di tahun 2011 tentang Light Fidelity (Li-Fi) pada forum TEDx menujukkan bahwa terobosan teknologi ini dapat dijadikan alternatif komunikasi masa depan yang mana memiliki kelebihan dibandingkan teknologi komunikasi wireless lain seperti infra-red, fiber-optic dan radio frequency, yakni bebas regulasi, cakupan bandwidth yang lebih besar, aman untuk kesehatan dan masih banyak yang lainnya. Sifat dari visible light adalah tidak dapat menembus objek padat seperti
