Li-Fi Technology Transform all the Major Industry Verticals Present in the World

Posted by BIS RSRCH on March 9th, 2020

Li-Fi technology is widely used in various applications such as healthcare, education, retail, aviation, exhibition industry, and others. Healthcare is one of primary application areas in the global Li-Fi market. Hospitals have always received technology in the form of wired connections. Though, the operations and other hospital activities were carried out without any hindrance, the commercialization of Li-Fi in the healthcare sector would lead to high speed data network in the hospitals. Li-Fi or Light Fidelity is one such solution which does not interfere with the radio waves.

With the advent of Li-Fi technology, human brain has given rise to a new phenomenon in the form of Li-Fi or Light Fidelity. Li-Fi, a wireless communication technology, which is expected to enhance the overall experience of the user by its user-friendly interface. With the constantly evolving technologies such as, 5G wireless broadband and Internet of Things (IoT), among others, Li-Fi technology is bound to expand to many more fields of applications such as healthcare, aviation, retail and education, among others, and transform all the major industry verticals present in the world today.

Li-Fi was first developed by Professor Harald Hass in the year 2011 based on the technique of Visible Light communication. Li-Fi technology uses LED bulbs for transmitting data where it acts both as an emitter and photodiode for detecting the light.  Unlike Wireless Fidelity (Wi-Fi), Li-Fi does not operate on radio waves making it even more useful in working with aviation and marine industries. The major driving force behind the popularity of Li-Fi is its reliability and fast response. Since the principle involves working with LED bulbs, the transition from CFL and bulbs into LEDs has become  a major driving force for Li-Fi technology.

Li-Fi is one of the emerging technologies that effectively turn LEDs to data transmitters. The Li-Fi enabled LEDs help create high speed, optical wireless communication that leverages the visible and infrared light spectrums. This is achieved through the modulation of light at various frequencies that are imperceptible to the human eye in most lighting applications. Semiconductors, majorly LEDs can turn on and off up to a million times per second, enabling the diodes to send data quickly.

The global Li-Fi technology market is expected to grow at a CAGR of 71.2% in terms of value during the forecast period 2018-2028. This growth can be attributed to the increasing demand for advanced data transmission technology.  Furthermore, the rising demand for higher bandwidth, advantages associated with Li-Fi technology and tremendous development in the Research & Development (R&D) for Li-Fi technology to overcome the technical challenges are expected to drive the global market for Li-Fi during the forecast period (2018-2028).

The factors driving the growth of the global Li-Fi market include adoption of light emitting diode (LED), superior properties of Li-Fi, and increased demand for wireless networks. One of the major driving factors for the significant growth in the global Li-Fi market has been the adoption of the Light Emitting Diode (LED) based lighting systems. This has improved the energy efficiency and is catering to the prevailing issue of the global energy crisis. Owing to these rapid technological developments and scientific innovations, companies have started to adopt solid-state lighting aggressively for minimization of the per unit costs, and at the same time, increasing their energy efficiency.

However, even with such enormous growth of demand, the global market for Li-Fi is facing immense challenges which include technical challenges, and lack of awareness regarding Li-Fi. One of the major factors acting as a restraint in the development of the Li-Fi technology is the fact that the Li-Fi signals can’t penetrate through walls. The Li-Fi technology uses visible light communication for the signal transmission. Since light cannot penetrate through walls, the communication is interrupted. Internet can only be used where there is light source available. The light can’t penetrate through the walls as it works only in the line of sight path. Thus, it is necessary to make sure that there is no obstacle present in between the LED lamps and the receivers and that the data is normally received by the receiver. This is because the presence of an obstacle between the lamp and the receiver can lead to a data loss.
