What is Li-Fi technology and why it intends to replace Wi-Fi | Link | Spain | Mexico | USA | Technology

The Technology Li-Fi, a type of connectivity Website Capable of transmitting information using light, it will replace Wi-Fi. This week, the Institute of Electrical and Electronics Engineers (IEEE) certified 802.11bp as the standard for light-based wireless communications. What exactly does it contain?

Abbreviations indicate ‘Light Reliability’ and was first used at the TED conference in 2011. University of Edinburgh professor Harel Haas pointed out at the time that light could be used to transmit data.

for its operation Flashing lights are used at speeds that are invisible to the human eye, whose changes occur in nanoseconds. When a photoreceptor recognizes patterns, it connects to devices.

Compared to Wi-Fi, Li-Fi offers several advantages. Because one of them is its speed It is 100 times faster than the most popular wireless connection. In addition, latency is low and security is high, as light-based operation prevents the intrusion of malicious actors.

Similarly, the modules placed on the devices are getting smaller.

however, One of its major drawbacks is short range. Because it is based on visible light, it is limited by obstacles that intercept it, such as walls. The Li-Fi point should not exceed 4 or 5 meters.

For this technology to reach a large scale, the components required for its use, such as special LED bulbs and receivers for devices, need to become cheaper in the future.
