LIFI takes on the IOT

Li-Fi Takes on the IoT

Does Li-Fi add a new dimension to the smart-city  interoperability discussion? I would suspect that most reading this  would agree that interoperability in smart cities is costly. In case you  need to be convinced, here is some research on the subject. In looking  at just one little tidbit from Machina Research it suggests that by  2025, cities could spend an extra $341 billion by adopting a fragmented  versus a standardized approach to IoT (Internet of Things) solution  deployment. On the other hand, a standards-based IoT environment could  improve innovation and adoption of smart-city applications, resulting in  a 27% increase in the number of connected devices within smart cities.
That all sounds impressive. But, I think we need to take a  step back and first look at what is Li-Fi, before we can truly engage in  a deep debate about smart cities. However, if you want to learn more,  listen to The Peggy Smedley Show Harald Haas interview and that will  help you truly understand Li-Fi.
Li-Fi is short for “light fidelity.” It’s a wireless  communication technology that leverages visible light for the high-speed  transmission of data between devices.  … What makes it so impressive is  that it leverages the visible light spectrum, ultraviolet, and infrared  radiation, to transmit data.
It’s very important to note that “Li-Fi” as a term first came  onto the scene in 2011 when Harald Haas, who you can listen to on the  podcast of The Peggy Smedley Show, gave his TED Talk, titled: Wireless  Data From Every Light Bulb,” in Edinburgh, Scotland. I would be remiss  if I didn’t note this TED Talk has been viewed online more than 2.4  million times. Haas is a professor of mobile communications at  University of Edinburgh and a researcher.
He has a particular interest in optical wireless  communications, hybrid optical wireless and radio frequency  communications, spatial modulation, and interference coordination in  wireless networks. He is also cofounder of PureLiFi, a company that’s  pursuing the innovation and adoption of Li-Fi technology wherever there  is light.
As for Li-Fi, it is similar to Wi-Fi, except of course for the  fact that Wi-Fi relies on radio frequency to transmit data, while Li-Fi  relies on the light emitted from LED lamps to transmit data. There are  several advantages of using light waves instead of radio waves to  transmit data.
Some of these include: higher bandwidth, faster transmission  speeds, and the ability to work in areas that are susceptible to  electromagnetic interference, like hospitals and inside airplanes.
Some other potential physical places that could benefit from  Li-Fi include power plants, petrochemical factories, and other areas  Wi-Fi can’t typically reach. Also, since light can be directed to  wherever it needs to be, it’s easier to avoid interference issues with  Li-Fi.
So where are we using Li-Fi in the real world? PureLiFi has  already come to market with a couple of products that leverage Li-Fi  technology and can be installed alongside existing lighting  infrastructures. Basically, anywhere communications are necessary and  light is available, Li-Fi is an option—from industrial settings to  public places in smart cities. Li-Fi promises to offer a lot of new  applications or enhance existing ones.
According to Global Market Insights, the Li-Fi market is expected to reach $75.5 billion by 2023.
Growing demand for spectrum, alongside limited availability of  spectrum, will certainly help this growth along. Concerns about data  security may also help push Li-Fi adoption in environments like  hospitals. Global Market Insights’ analysis also suggests Li-Fi’s  marketshare in intrinsically safe environments that can’t tolerate the  use of Wi-Fi will experience a 88% CAGR (compound annual growth rate)  between 2016 and 2023.
In smart cities, the possibilities are really exciting. There  have been tests, for instance, that explore the use of Li-Fi in disaster  situations, and they have proved successful. Li-Fi also has potential  applications in guiding sight-impaired passengers on public transit  systems, measuring customer journey times through supermarket aisles,  and offering ultrafast, secure Internet access for citizens.
I’m thinking about even more use cases, like enabling  connectivity on military bases, enabling data transmission in  transportation infrastructure like traffic lights, and even enabling  vehicle-to-vehicle communication with Li-Fi-enabled headlights. This is  where the IoT really shines.
Think of all the “things” that could benefit from Li-Fi  connectivity. Li-Fi isn’t the solution for everything, of course. Li-Fi  requires light, so enabling public Internet access through Li-Fi would  require constant light sources, and that may not be plausible. Also,  Li-Fi is limited by physical barriers, since light can’t penetrate  walls.
Depending on the context, this last limitation could actually  be considered a good thing. For instance, if you’re using Li-Fi to  connect to the iInternet in your home or business, no one outside of an  LED’s direct light could piggyback on your network.
At this point, you may now be also be asking: What’s the  future of Li-Fi? Let’s be clear, I am not suggesting Li-Fi will replace  Wi-Fi. At this point it appears that Li-Fi and Wi-Fi are complementary  technologies, and Li-Fi will not replace Wi-Fi. Each technology has its  strengths and its limitations. By working together, Li-Fi and Wi-Fi  technologies will open doors for smart-city connectivity in more  environments than Wi-Fi or Li-Fi alone. But like any technology we  always have to keep an open mind. The skies the limit on what it can do  and where it can go.
Li-Fi will help reduce the issues we’re expecting to run into  around spectrum as more and more connected devices in cities transfer  critical data that can enhance decisionmaking. Personally, I’m excited  to see how Li-Fi enhances our cities and helps make them smarter and  more connected. If we give innovators a way, they will innovate beyond  our expectations every time.
However, the road forward isn’t without its speed bumps. What  we have been talking about in smart citis is interoperability, and no  matter how we connect—be it Li-Fi, Wi-Fi, cellular, or something else—we  need to make sure our devices and systems can talk to each other.
If they don’t, we’re seriously limiting the ways data can  inform and enhance our cities. We, as an industry, need to work together  to implement standards that allow connected devices to communicate. If  we do, the ecosystem will certainly flourish. Li-Fi is going to help  grow the IoT, enhancing connectivity in our future cities, and I can’t  wait to see where it goes.
But let’s not put the cart before the horse. Issues like  interoperability and security need to be top of mind in every single IoT  conversation.
