Wireless fidelity or Wi-Fi has been used as a standard connection to access the internet or a private network. While it serves a faster connection than Bluetooth, many people experience problems with Wi-Fi every now and then. An ongoing research has given birth to a better wireless connection, it is called Li-Fi or light fidelity.

Light Fidelity: Wireless Connection of the Future

According to the University of Edinburgh in Scotland, modulations for light fidelity can provide a cellular wireless network using lights. The type of lights that can use Li-Fi is the LED bulb because of the visible light transmitters. When commercially available, the LED bulbs serve as a source of illumination and network access to the internet.

Philips is currently working on the technology to make it the new standard for connection, particularly in devices ifalling under the Internet of Things. According to the company, Li-Fi offers a different way to support internet connectivity compared to Wi-Fi. In Wi-Fi, users are prone to bandwidth sharing by each member of the household who knows the password. Moreover, multiple Wi-Fi networks in a single area can disrupt each other that leads to slow connection speed.

In Li-Fi, the data is sent through light waves regulated by an LED light source and received through an integrated infrared sensor. Users in an internet zone using Li-Fi connectivity can connect easily via a personal USB access key. 

Advantages over Wireless Fidelity

Several industries can receive great benefit from Li-Fi, especially those that rely on IoT, such as the corporate, government, and healthcare sectors. The main benefits of Li-Fi include the following:

- Li-Fi relies on light waves rather than radio waves in Wi-Fi. It does not create interference indoors that could disrupt radio frequencies.

- More secure compared to Wi-Fi. Li-Fi only supports specific light zones and does not cross physical barriers, unlike with Wi-Fi. Additionally, it requires a USB access key or dongle to receive and emit light waves needed for connection.
