LiFi is a recent advancement in Wireless communication that claims to deliver data at the speed of light.
“A team of researchers at the Fraunhofer Henrich Hertz Institute (HHI) in Germany has developed a Visible Light Communications (VLC) or LiFi system that while using conventional LEDs has successfully transmitted data at 3 Gb/s in a laboratory environment” – Extreme Tech
What is LiFi?
LiFi is commonly known as Light Fidelity in which data transmission is achieved through visible light instead of radio waves. It is similar to Wi-Fi in nearly all aspects except that it transmits light using Light Emitting Diode (LED) instead of Wi-Fi transmitter that transmits radio waves.
How does it work?
Working of LiFi is pretty simple. Light from LED bulbs is detected by a photo-detector (i.e. a light sensor incorporated into your device). As soon as it detects the direct incoming light, transfer of data from one place to another starts at the rates in the range of hundreds of megabits per second.
How practical is it?
With LiFi, you can easily download a high definition movie in just 30 secs!
The purpose behind coming up with the idea of LiFi is to allow exchange of data between several devices at higher speeds that is achieved by simply giving off light from LEDs at a distance of upto10meters.
As light cannot penetrate or pass through walls, this is the biggest advantage of LiFi as compared to radio waves that have high penetrating power. This makes LiFi a threat to Wi-Fi because it doesn’t allow interference. Many organizations that deals in critical information related to aircraft systems welcomed LiFi with an open heart.
. Why would someone switch on the LED bulbs in day time?
Critics raised a very valid point by placing this question in-front of inventors; at one hand they are concerned about energy and claim to conduct programs to conserve it while on the other hand they are promoting energy usage even in the daytime by inventing such gadgets. However, this question still remains unanswered.
. You can access data only if your device can see the light
LiFi is restricted by line of sight. If you want to access data, you must place your device at a position from where it can catch light easily.
Speedier Data Transfer Rates
For greater transfer speeds, LEDs of different colors could be used that vary light intensity. Data can be sent at a speed faster than the normal human eye can follow.
In short, if LiFi becomes a reality, it would make the wireless internet life quite flexible without the hassle of blocked signals or stolen bandwidth.

At Genetech we pride ourselves with our 'open communication' approach with our clientele. Once you initiate a project with us, be it big or small, our team will provide regular updates, regarding project status. We encourage our clients to interact with us as much as possible; so that we can deliver exactly you're looking for. As a team, we put in a lot of dedication and finesse into everything we create with you, so that you're thoroughly pleased with the outcome. As we begin all our projects from scratch, each plan is molded to most efficiently accomplishing it purpose. Backed up with solid coding and fresh designs, our work aims to impress. Finishing off with a strenuous QA run, all work is built to function smoothly.
I have had the pleasure of working with Genetech for several years now. I would not work with any other group. The projects have been varied and have included website design (they have done multiple sites for me and are always unique and creative), app development (multiple projects) and also using their dedicated developer service. In all of these areas, I have found Genetech to be knowledgeable, on time and willing to take on projects that have been unusual and outside the norm. Genetech's people always go above and beyond and I feel they are part of my company! In regards to their app development, I cannot overstate their expertise and also their fearlessness to take on projects that are outside the norm and over deliver on the final product. I have recently taken advantage of their dedicated developer service and have been extremely happy with their response time and their the ability of the developer to think "outside the box" when needed. The major part for me is the communication. Initially I was concerned about the ability to communicate with an overseas programmer but with Genetech there has never been an issue. Their response time and ability to understand my needs has been beyond my expectation. I would work with no one else and highly recommend Genetech and have recommended them to many colleagues.
