Also, LiFi is said to increase bandwidth by 100 times what we have today with WiFi. When looking at the comparisons between WiFi and LiFi, it would be very difficult to choose one over the other as both have their own merits – and their own disadvantages. This is where LiFi comes in. Lastly, users are rendered immobile when using LiFi systems due to the limited range of the signal given off by light bulbs. About 1 Gbps (that’s a lot of fun) Distance Covered. Data rates as high as 3.5 gigabytes (GB) per second using a single blue LED, or 1.7 gigabytes (GB) per second with white light, have been demonstrated by researchers. Due to this heavy dependence on WiFi, many are stuck on this concept as the best mode of wireless communication. This is, of course, countered by installing multiple LiFi systems within large spaces, creating as many connections as there are light bulbs. WiFi operates within the radio spectrum. Both the technologies LiFi and WiFi co-exist together based on their respective unique features. It is very popular because it allows users to access networks without the need for a physical wire between the device and the transmitter. Its lack of security generally comes from its wide signal range, allowing the network to be accessed within a 20 to 50-meter radius. WiFi has invaded virtually all facets of human society – from the domestic setting and business, to basic government services such as ICT and transportation. Recent tests have shown that Lifi is capable of providing the speed of 1GB, which is incredible. Li-Fi technology makes use of infra- red or visible light communication and it lays near ultraviolet waves instead of the regular radio- frequency waves. LiFi transmission speeds can exceed 100-300 Gbps, which is 14 times faster than WIFI, LIFI is also known as the world’s fastest wireless network system. Additionally, internet access through WiFi is easy to implement. Even when the connection is protected with a password, others may attempt to hack into the network, leaving all private data vulnerable. Since LiFi technology is a relatively new concept and is currently in its introductory stage, the infrastructure necessary to implement the technology in a large enough scale is still virtually non-existent. Waves emitted within this frequency range, called radio waves, are widely used especially in telecommunication, making it prone to interferences occurring at various frequencies.
