Wi-Fi to Li-Fi: The Future of Wireless Connection

Li-Fi powered office

Imagine activating your appliances by just using the flash on your phone. Efficient right? But how about your lamp beams out internet to your laptop. This is already happening in some smart buildings and could be a norm in the future. Thanks to mankind’s intelligence, we can now benefit Li-Fi or Light Fidelity.

Highly used on almost around the world, WiFi functions by the use of radio waves to transmit information across a network. Li-Fi uses visible light communication (VLC) or infrared and near-UV spectrum waves. In other words, Li-Fi works by using visible light, like the light that is emitted by any regular lamp or bulb

“While radio frequencies are becoming congested, the visible light spectrum is an untapped resource with a large bandwidth suitable for the stable simultaneous connection of a vast array of Internet of Things devices,” -Olivia Qiu, chief innovation officer at Signify


Many people have grown fond of the concept of WiFi and for a good reason, it has invaded virtually all the components of human society- from domestic setting and businesses, to basic government services such as transportation. Due to society’s heavy independence to WiFi, many are stuck for its concept as the best mode of wireless communication. For this reason, people seem to remain unfamiliar to a similar concept known as Li-Fi – even though the concept has been around for many years.

Ideally speaking, Li-Fi systems is not created to replace WiFi altogether. When looking at the comparison, both have their own merits- and their own disadvantages. Considering that most of the existing infrastructure has already been built to accommodate technology, it would be very costly and tedious to replace all of that infrastructure to give way to a newer technology. For this reason, Li-Fi needs to be looked at as a complementary technology that aims to improve the performance of the existing technology and provide relief to the already congested radio spectrum used to provide WiFi connections.

Data connection has become an essential commodity in our daily life. Like paying the bills, ordering food or even making transactions. WiFi connections are everywhere but sadly, we can’t use it forever. More and more users of this wireless connection occupy the radiofrequency of WiFi leading to a spectrum crunch.

Spectrum crunch refers to the potential lack of sufficient wireless frequency spectrum needed to support a growing number of consumer devices.

Wireless data has become an essential commodity in our daily life. Wi-Fi is everywhere but sadly; we can’t use it forever. Radiofrequency, the technology that powers Wi-Fi, is running out Spectrum crunch is a risk in telecommunications and wireless networking with profound implications for the immediate future.

According to Li-Fi Co, in 2016, in 2016 mobile data traffic grew by 63% which is an indication that it will continue to grow and almost half a billion (429 million) mobile devices and connections were added in the same year alone. By 2021 there will be 1.5 mobile devices per capita. There will be 11.6 billion mobile-connected devices by 2021, exceeding the world’s projected population at that time (7.8 billion).

Eventually, Wi-Fi will not be able to keep up with the demand of data and the world needs to future-proof our networks to fulfill the connectivity demands of tomorrow. With Li-Fi, we can utilize spectrum more than 1000 times greater than the entire spectrum used for radio frequencies. Li-Fi allows significantly more access points than WiFi’s radio frequencies, achieving the higher data rates necessary due to an ability to produce small cells necessary for faster connectivity.

The speed of Li-Fi technology not only lies on its speed. It will save costs in homes and workplaces because it could do without electronic devices such as routers, modems, signal repeaters, wave amplifiers, and antennas. Currently, these devices are connected to power 24/7. Since Li-Fi is connected to LED bulbs, using the technology would not be an extra cost.

The value and the philosophy that comes with the style are what makes Japanese interior design timeless. The interiors are laden not just with functional furniture, but with ideologies concerning life.

Also in the near future, it has been estimated that we will be able to transmit data through solar energy. That means the people without internet access or with limited electricity resources will now be able to connect to the web wireless.

Li-Fi is more secure than technologies like WiFi for the simple reason that light can be contained in a physical space, so that no unsolicited connections is possible. With Li-Fi, we can create the conditions that allow us to have maximum security on our wireless data.

Lastly, Li-Fi is environmentally friendly. Li-Fi has a low energy consumption because it can be incorporated in energy efficient LED lighting technology. While LED lightbulbs are more expensive than standard lightbulbs, using LED lighting has many advantages to the environment.
