Market Research analysts forecast the global visible light communication market to grow at a CAGR of 77.86 % during the period 2017-2021 .
The following companies as the key players in the global visible light communication market : fSONA Networks , GE , LightPointe Communications , LVX System , Nakagawa Laboratories , Oledcomm , Outstanding Technology , Koninklijke Philips , and pureLiFi .
Other Prominent Vendors in the market are : Avago Technologies , Axrtek , ByteLight , Casio , IBSENtelecom , Lightbee , Luciom , Panasonic , Plaintree Systems , Renesas Electronics , and Supreme Architecture .
Commenting on the report , an analyst said : One trend in market is adoption of LEDs . The energy efficiency , longevity , and cost effectiveness of LEDs will boost the adoption of these lighting devices . LEDs will gradually replace all fluorescent and incandescent lights in the market in the near future . The possibility of using LEDs for lighting as well as communication will likely be a factor that will speed up the adoption of these lights . For instance , if the lights in offices and houses are replaced with LEDs , free space optical communications can be achieved . This will allow wireless optical communication between phones , computers , sensors , and other indoor devices such as office and household applications . This model is also simple and easy to implement as it requires no additional hardware or infrastructure .

According to the report , one driver in market is availability of greater bandwidth . With an enhanced lighting technology , VLC will offer a much greater bandwidth . The illumination LEDs that are currently in use are designed to be of low bandwidth , as they are supposed to deliver a constant illumination at high power . Nevertheless , the sector is moving toward RGB , where each individual channel has a higher bandwidth . One can also add several different colors to multiplex that is over different channels . For instance , laser LEDs are incorporated in BMW i8 headlights to have a very long range communication , and these have even higher bandwidths . The bandwidth frequency spectrum offered by visible light is larger than that offered by RF bandwidth . VLC bandwidth ranges from 400 THz to 800 THz , and RF frequency offers a bandwidth range from 3 kHz to 300 GHz .
Further , the report states that one challenge in market is design limitations . The receivers use an imaging sensor or photodiode for receiving signals . Photodiodes are used in stationary devices , and mobile devices use the imaging sensor due to the larger field of vision . However , image sensor operations are slow and consume more energy . This affects the overall data rate as the imaging sensor is designed for capturing images and videos and not for communication . Hence , it is a challenge to design the receiver that offers strength to device movements and FOV misalignments .
