The growing need of green technology solutions with low power consumption is encouraging the development of advanced communication systems and visible light communication (VLC) is expected to grab a substantial portion of the Wi-Fi industry in the near future. However, the adoption is at the nascent stage and is currently being used for niche applications, due to which, an extensive R&D investment would help market players to obtain a competitive advantage, says the report.

High illumination, longer life and low power consumption of has led the implementation of LED as a component in Li-Fi (Light Fidelity) systems. Government promotions for smart LED bulbs in developed countries such as the U.S., and the UK are expected to provide a massive infrastructure base to the VLC system providers.

Increasing applications of indoor location-based services embedded with light fixtures in retail shops and hotels is projected to be one of the factors driving revenue growth. Several companies such as GE Lightings, ByteLight, and Koninklijk Philips N.V., are deploying VLC installations in supermarkets which in turn is aiding retailers to tie customers’ shopping history by tracking their location details. This is helping the retailers to deliver on-site information tailored to a customer needs, notes the market research firm.

Advancements in the automotive industry are projected to enhance the safety of commuters. This is being executed through the vehicle to vehicle (V2V) and vehicle to the roadside (V2R) communication by installing LEDs in headlight and tail light of the vehicle. However, high installation and repair cost are projected to obstruct the large-scale implementation of these systems, especially in the emerging economies.

The reports splits the market by components as LED, photodetector, and microcontrollers. LED-based VLC devices accounted for over 40% of the revenue share in 2015. These can be switched on or off to generate a digital string of binary numbers. The data can be encoded in the light using the mixtures of red, green and blue LED by varying flickering rate to alter the light frequency.

The component assists in transmitting the data using the different part of the spectrum. The advancements in LED have contributed to the solution wherein light is used for high-speed wireless communication.

Photodetectors accounted for over 30% of the revenue share in 2015. Commonly used photodetector such as a photodiode are utilized for sensing and detecting images in the transmitted signal. Microcontrollers help in modulating the data using different modulation technique such as pulse width modulation (PWM). Microcontroller component segment was valued at over USD 95 million in 2015.
