The visible light communication (VLC)/light fidelity market is growing at a considerable rate, due to increasing government funding, absence of capacity or bandwidth limitation, growing research and development activities, along with safer and faster data transfer, as compared to the other technologies. Penetration of visible light communication (VLC)/light fidelity in advanced applications, global acceptance by the electronic devices manufacturers, and bandwidth crisis in wireless fidelity (Wi-Fi) technology, are some of the factors providing ample growth opportunities to the visible light communication market, in the coming years.
Visible light communication technology is an optical wireless technology, which is used as a method for data interference. Through this technology, light could be detected in the visible region only. Light fidelity is a wireless communication, which is used for data broadcasting with the help of visible light communication. Several researches are undergoing within the research centers to commercialize and develop gigabit networks, for extended range communications; which in turn is supporting the growth of the visible light communication market, in the coming years. Visible light communication technology is still in it innovation phase, as the indoor networking and location based services, only provide limited functions. The visible light communication is expected to become a balancing technology, for the available wireless system protocols, in the coming years.
Visible light communication is expected to gain importance in various fields, such as power over Ethernet, smart cities, augmented reality, ubiquitous networks, wireless sensor networks, and machine-to-machine contact. At present, there are no registration regulations, and standards for visible light communication technology implementation. Additionally, visible light communication technology reduces additional operating expenses, such as electricity charges and maintenance charges. However external light sources, such as bulbs and sunlight, and opaque materials cause interference, in the communication path of visible light signals.
On the basis of components, the visible light communication market can be categorized, as transmitter, modulation, interfaces, receiver, software, demodulation, and link management system. The receiver includes photo diode receivers, charge coupled device (CCD), and complementary metal oxide semiconductor (CMOS) sensors. Demodulation includes synchronous detector and diode detector; while the modulation includes pulse amplitude modulation, pulse width modulation, orthogonal frequency division multiplex, variable pulse position modulation, frequency shift keying, spatial modulation, color shift keying, and pulse position modulation.
The visible light communication market can also be categorized, on the basis of applications, as aerospace, communication, smart stores, casinos, underwater communication, automotive, healthcare, and museums. Its application in healthcare includes operation theaters and asset tracking; aerospace includes in-flight network connectivity; and underwater communication includes flow of information in underwater communication. The application of visible light communication in Automotive includes location based service, vehicle-to-infrastructure communications, advanced traffic management system, vehicle-to-vehicle communication, advanced traveler information system, and advanced public transportation system.
Some of the factors driving the growth of the visible light communication market are greener, cleaner and safer technology, along with less energy consumption, in comparison to other technologies. The competing technologies and lack of technology awareness among consumers are some of the factors, restraining the growth of the visible light communication market.
