Taking into account that the spectrum in which WiFi networks work is increasingly saturated, it is to be expected that technologies such as fiber little by little to position themselves as a viable solution for the future. And that is what we have been taught in the offices of Signify (formerly Philips), since we have had the opportunity to learn about the new system trulifi.
What is Lifi?
If you're still not up to speed on new wireless communication technology, it's time for you to meet LiFi. It is a communication system that instead of using radio waves as Wi-Fi does, is based on light signals that are imperceptible to the human eye, a method that is capable of offering superior performance in terms of speeds and bandwidth. band refers.
Unlike WiFi, Lifi requires direct line of sight between transmitter and receiver to obtain maximum performance. It can work by receiving the signals bouncing off walls, although this greatly reduces the communication speed. Of course, something that is not possible to do today with LiFi is to communicate through obstacles, such as a wall in a room.
Today Meaning unveiled #trulifi, the world's fastest commercial LiFi systems. They may be used where conventional wireless communication fears to tread: in offices, hospitals, anywhere where conventional wireless in not permitted or security is an issue. https://t.co/EdD1fvAPza pic.twitter.com/ilMTRaDmix

What new features does TruLifi offer compared to the original Lifi?
The new TruLifi generation developed by Signify is capable of achieving transfers of 150 megabits per second, a speed that represents a considerable improvement compared to the 30 mbps that were reached with the previous generation. The new systems arrive through adapters integrated into Philips lamps, although they can also be connected to luminaires that are already installed, so their implementation is quite flexible.
The adapter incorporates an ethernet port in which we will connect a cable with the network signal, and the Trulifi emitter will be in charge of carrying out the connection through light signals. On the user side, the connection device that exists today is a USB adapter that we will connect to the computer, a peripheral that will be in charge of interpreting the light signals into data.
The new models of adapters presented are the following:
- Trulifi 6002: The adapter that we can place in lamps.
- Trulifi 6013: Professional-oriented adapter that uses two colored lights to create light links with speeds of up to 250 Mbps in a point-to-point connection up to 8 meters away.
Can we buy Lifi systems now?
If technology interests you and you think it can be a good solution for your home, we must tell you that the systems are still geared towards the professional sector. Due to the early age of the technology, for now the first steps are more focused on professional uses where connection reliability is required, absence of contamination by waves and safe environments in which external communications are tried to be avoided (Lifi is ideal for this, since communications could not leave a closed room).
