Thanks for taking an interest in pureLiFi and our LiFi story.
LiFi is a disruptive technology which will shift business models, creates opportunities ripe for exploitation, and is on track to become a $113bn industry by 2022.
You will have read about the possibility of LiFi achieving speeds of 1Gbps in real-world use (which is faster than superfast broadband), and that is something we are working on right now. Please find below a bit more information on the technology, its benefits and how pureLiFi is looking to deliver LiFi technology to the market.
What is LiFi?
LiFi is high-speed, bidirectional, networked and mobile wireless communications using light (as opposed to traditional radio frequencies). The term was coined by Prof. Harald Haas and is recognized by the IEEE standardization committee for Optical Wireless Communications.
With LiFi technology, data travels in the visible light spectrum through LEDs. This makes it possible to provide wireless internet access at speeds of over 100 Gbps, although this is still in the Lab.
What’s the difference between Visible Light Communication (VLC) and LiFi?
VLC is a the overall concept in that includes unidirectional and low data speed transfer of data, unlike LiFi, VLC does not typically provide wireless Internet access. One could argue that even smoke signals are technically VLC. This is how modern VLC works.
LiFi is different from VLC in:
- Roaming – allows users to move freely between lights and maintain a Skype Video Call.
- Multiple Access – a single light can let different people browse the internet at the same time.
Benefits of LiFi
LiFi technology provides many benefits for users including speed, energy efficiency and security.
In our tests, LiFi has produced speed of over 100 Gbps (in a controlled environment). These speeds can be achieved due to low interference (compared to radio frequencies), and high bandwidth due to the visible light spectrum which is 10,000 times more than the RF spectrum and allows for optimal users coverage no matter the number of users.
WiFi signals penetrate walls and ceilings, LiFi signals can only be received in the area lit, yet allows for roaming between lights. LiFi is confined to the illuminated area, providing a very controllable environment. The signals cannot travel through walls and are fully secure – essentially eliminating the threat of data being hacked remotely. There is therefore no risk for remote piracy through the LiFi system. This solution is of great interest to sensitive operations such as R&D, defense, banks, security systems, etc.
- Energy Efficiency
Energy consumption is minimised via the use of LED illumination, with the transmission of data requiring negligible additional power.
- Safety – an alternative to radio waves, with potentially harmful effects
Visible light wavelengths are harmless to humans, even beneficial at specific wavelengths. LiFi comes as an alternative to radio waves which is a key characteristic to sensitive environments such as hospitals, medical centers, schools, some industrial installations…
- Data Density
The area covered by one Wi-Fi access point has 10s or 100s of lights. Each LiFi light can deliver the same speed or greater than a Wi-Fi access point. Therefore, in the same area, LiFi can provide 10x or 100x or 1000x greater wireless capacity. That is Mbps per squared meter.
The dense location of lights can be used for positioning and location based services (LBS) to deliver robust positioning and reliable connectivity.
The LiFi Myths
- LiFi is not “100x faster than WiFi.” The latest WiFi standard (IEEE 802.11ad) or Wi-Gig supports data rates of 7 Gbps. LiFi has never achieved 700 Gbps.
- The type of light source (large LED light, smaller LED lights, laser LEDs, etc.) directly impact the speed that can be achieved by a LiFi solution.
- Laboratory experiments have achieved 100 Gbps with laser LEDs. This impressive result is over 10x faster than the fastest Wi-Gig.
- Internet speeds depend on the Internet Service Provider as much as your WiFi access point. LiFi data rates will be limited by what is offered from the Internet Service Providers.
Our LiFi Timeline
pureLiFi has announced its collaboration with French LED lighting specialist Lucibel. This collaboration will develop Europe’s first LiFi light prototype. The product is expected to go to market in late 2016, with the first installation going into Sogoprom’s new headquarters at La Défense, Paris. For more information click here.
