Sounds like a world of science fiction but the technology actually already exsits! It will take coordination from various industries to encourage mass implementation of this technology. In addition to avoiding the use of radio waves that are potentially harmful to human health, LiFi can also be a substitute for 3G or cable connections. Public WiFi is a form of convenience that’s taken for granted these days. With LiFi, every source of light can connect you to the internet. This advantage is the reason why proponents have banked on Li-Fi as a solution for resolving that issues involving the bandwidth limitations of Wi-Fi and the growing amount of data produced and consumed by users. In fact, according to Energias Market Research, the LiFi market is expected to reach over $80 Million in 2023. This means that a Li-Fi network can be integrated easily with existing LED lighting systems. Remember that the data transmitted by a Li-Fi product remains confined within a close spaced because light cannot penetrate opaque objects and has a shorter range. The promotion of further connectivity is another advantage of Li-Fi technology. Li-fi is an innovative idea in IT, one that aims at eventually replacing radio frequency wireless signals with those that come from light sources. Nonetheless, because of the purported advantages of this technology, proponents have positioned it as an alternative to existing Wi-Fi and WLAN technologies. Aug 23, 2018 - This Pin was discovered by RP3 Enterprises / Rp3ent mobil. Remember that light waves cannot penetrate through walls and doors. Data transmission over Li-Fi is a hundred times faster than data transmission over Wi-Fi. eBook topics. This will save costs in homes and workplaces because it could do without electronic devices such as routers, modems, signal repeaters, wave amplifiers, and antennas. It is important to note that some medical instruments used in hospitals, as well as the radar and communication systems in an aircraft are sensitive to radio frequency. In open spaces, Wi-Fi’s coverage can go up to 32 meters but LiFi can only go up to 10 meters. LiFi 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. An entrepreneur and executive with a passion for enterprise technology, Doug founded Solutions Review in 2012. They also have a shorter range. The main disadvantage of lifi is that the light can’t pass through objects, so if there is any object or any wall in between sender and receiver the signal will break at once. Prof. Harald Haas has been labeled the Father of LiFi for his efforts in development of this technology. In areas or countries that are notorious for having slower Internet speeds than their counterparts, deploying a Li-Fi network would be meaningless. A star-delta starter is the most commonly used method for the stating of 3 phase induction motor. In establishments such as house or building, enabled LED lamps must be strategically placed in rooms, halls, and other sections to expand the scope of the Li-Fi network. Most devices that we use now still use hardware for Wi-Fi networking and it’s unlikely that we will see LiFi enabled personal devices in the next couple of years.
