People use Wi-Fi technology to access the Internet and exchange information, but this technology is unable to withstand the enormous pressure with the increasing number of users, especially with the entry into force of the “Internet of Things” technology, where most home and electronic devices have become connected to each other.
The demand for mobile communications has increased at a significant rate, leading to what is known as the “spectrum crisis,” which is concerns about the potential shortage of radio frequencies to support the requirements of an increasing number of devices. Therefore, new technologies are being developed to overcome these obstacles. One of these technologies is known as “Li-Fi”.
Li-Fi is designed to use energy-efficient LED lights, similar to those currently used in many homes and offices. However, “LiFi” lights are equipped with a chip that modulates the light imperceptibly to the eye to transmit data, to be received by photoreceptors.
Tests revealed that “Li-Fi” technology can reach speeds 100 times faster than current “Wi-Fi” systems. For example, it can download at a speed of 1.5 gigabytes per second. Most importantly, this technology does not interfere with radio signals.
The use of Li-Fi technology in homes and offices can eliminate the need for many electrical devices, such as routers, modems, signal repeaters, wave amplifiers, antennas and power banks.
