THIS IS HOW LIFI WORKS, USING LIGHT TO CONNECT TO THE INTERNET
LiFi (Light Fidelity) arrives in Colombia from the company Signify, formerly known as Philips Lighting, a worldwide benchmark in lighting.
With LiFi, Signify has created a technology that allows access to broadband internet through Philips LED lights. Simply connect an Ethernet cable to the lamp, which then becomes a router. The light, which is modulated at a frequency imperceptible to the human eye, sends the data. These are received and forwarded by an integrated infrared device that connects to a USB port on the computer.
So, unlike WiFi, LiFi uses light waves instead of radio waves to transmit data bidirectionally. However, it is important to keep in mind that LiFi does not replace WiFi, but complements it instead, especially when radio waves are congested or weak.
“LiFi has important benefits for users, as it perfectly complements Wi-Fi, a band that is already reaching saturation point. This is a reality and if today our broadband capabilities are being overcome, in ten years, when virtually any computer will be able to connect to the Internet, the situation will be much more critical, so it is extremely important to have alternatives,” explains Felipe Uribe Correa, General Manager of Signify for North Latin America.
Jorge Jusdado, Commercial Director for North Latin America, adds that LiFi is “a complement to connectivity. We already had it by cable and by WiFi, which works by radio frequency, and now we will have it thanks to lighting. This represents a huge transformation. Our generation has grown up watching street lights turned off during day time; with LiFi, given the service provided by this lighting, the next generations may get used to seeing the street lighting on during the day.”
Speed, Stability and Security
In addition to serving as a complement to WiFi, LiFi offers great advantages. One of them is speed. This is because the office lights that Philips has developed and that are enabled for this technology provide a broadband connection with a speed of 30 megabytes per second without affecting the quality of the lighting. This gives the possibility to users to simultaneously transmit several videos in HD quality while making video calls.
We must also take into account that with LiFi, unlike WiFi, the 30 megabytes are not distributed among the connected devices, but each one of them fully receives that speed.
LiFi technology has more advantages. For example, it allows a stable connection in places where radio waves can interfere with equipment, such as hospitals, or in places with poor propagation or very little intensity, such as in underground spaces.
“LiFi also stands out for its high level of security, because light does not penetrate walls, so the chances of hacking the connected equipment are reduced. This makes LiFi a very interesting solution, for example, for financial institutions,” adds Jusdado.
In fact, more than thirty companies from Europe, North America and Asia are conducting pilot tests with LiFi. Now, Signify is aiming at Colombia as a new commercial target: “Expectations are high, because this is an interesting market; it is growing, is healthy and demands innovation, so we are very excited to offer innovations like LiFi to Colombians,” concludes Uribe Correa.
