1. LiFi, like WiFi, enables electronic devices like computers,
laptops and smartphones to wirelessly connect to the Internet. In
simple terms, LiFi is equivalent to WiFi, but using light waves
instead of radio signals.
2. The general term visible light communication (VLC), whose
history dates back to the 1880s. In July 2011 Prof. Harald Haas
coined the term LiFi at TED-Global 2011. In October 2011, companies
and industry groups formed the LiFi Consortium.

5. Congestion Factor The impending crunch of bandwidth is a
factor that has remains an issue. From what we had in 2011, we have
only a fraction of it. Hence need for alternative sources in
electromagnetic spectrum arises.
6. Cost Factor: LED Light Bulbs Because of technology spillover
and advancements in manufacturing technology and research, now the
cost of LED light bulbs have fallen drastically. Price Difference
2010: 40 USD 2016: 3-4 USD 2020: None
7. Cost Factor: ICs (Poly-Silicon) Since half a decade we have
observed a steep fall (approx 30 Times low) in the prices of
Poly-Silicon material, which is a key constituent in the
manufacturing of Integrated Circuits. Signal Receivers are designed
8. Other Factors There are other relevant factors which drives
us to think of an alternative technology altogether.
9. Internet is received in terms of stream of bits of 1s and
0s. Lamp Driver converts this stream of bits into sequence of
signals to turn the LED on and off at rapid rate
10. Unidirectional???? Special LEDs??? NO!!!
11. No Line-of- Sight? Reflection to the rescue!!
12. Microcontroller forms the heart of the LAMP Driver Circuit.
It holds the software operating system, network protocols. It
provides remote maintenance capability.
13. MCU = Micro Controller Unit
14. Spectrum of visible light is broader and 10000 times higher
than radio waves. It has been predicted spectrum crunch in UK by
15. Coverage distance of WiFi is about 32 meters varies LiFi 10
meters. These accounts higher speed in LiFi about 3 Gbps but in
WiFi about 500 Mbps.
16. VLC = Visible Light Communication Data is transmitted by
bits in serial fashion in WiFi varies parallel in LiFi. Speed is
controllable in LiFi through varying intensity of light but not in
WiFi. LiFi works well in dense environment but not WiFi.
17. WiFi LiFi
18. Security LiFi is more secure due to non penetration of
light through walls but Wi-Fi less secure due to transparency.
Compatibility LiFi is compatible with IrDa(Infrared Data
Association) devices and on the other hand WiFi with IEEE 802.11
19. Since LiFi makes use of electricity of LEDs that reduces
power consumption for data transmission when compared to Wi-Fi, it
is more cost effective and replaces the additional need of power
consuming light bulbs.
20. Cost Installation cost of LiFi Technology is initially a
bit as it replaces bulbs with LED lights that are equipped with a
small microchip that combines two basic functions illumination and
wireless data transmission. After change in technology to VLC the
maintenance and installation cost is considerably reduced when
compared to WiFi as it doesnt require routers.
21. Dense Urban Environments High Demand (Especially Developing
Nations) Underwater Communications Vehicles & Transportation
Healthcare Mobility Services Ambulance with Data Transfer Abilities
Aviation Data Security
22. At the moment, large-scale implementation of VLC is usually
complemented by high installation cost of the VLC systems. Hence
only large corporations and institutes can afford it. Though with
rising demand and more investment, it is bound to be cheaper and
cheaper. We cant have a light bulb that provides data to a
extremely high- speed moving object or to provide data in a remote
area where there are trees and walls and obstacles behind. Current
research claims to fix this issue. Since it is a new technology,
the technology spillover effect is very limited.
23. If the apparatus is set up outdoors, it would need to deal
with changing weather conditions. Infrastructure Dependency, i.e.
LiFi Enabled Devices are yet to be seen in the global market. Until
there is a viable number of devices available for the users, the
willingness to go for the technology shift may vary, especially for
the common users. We become dependent on the light source for
internet access. If the light source malfunctions, we lose access
to the internet. Though the risk of hardware failure is same in the
case of WiFi modems. Reliability and Network Coverage issues could
come into light once users start using the product. Interference
from external light sources may or may not affect the overall
performance. It is a fear and not certain possibility.
24. Look at the DOWNLINK and UPLINK data transfer speed. ITS
SAME!! Can you imagine that with WiFi? Not Yet I believe.

26. LiFi is a disruptive technology which will shift business
models, creates opportunities ripe for exploitation, and is on
track to become at least a $113 bn industry by 2022.
27. Installed base for LED more than tripled within a span of
two years and is expected to acquire 25% of installed base share by
28. An industry expected to grow by 82% as per CAGR means
29. According to the Optics Industry forecast, the market of
VLC components and technology enabled by them will more than double
from 2007 onward. It predicts a 1.7 trillion USD market by 2017. We
simply cant ignore it. Can we?
30. If a business is developed over the LiFi technology, its
potential customers could be segmented into three groups. Tech
Intensive Customers - MNCs - Research Labs - Defense Agencies Mid
Level Clients - Schools, Universities and Colleges - Hospitals
(Data Integration) Tertiary Customers - Going to be instrumental in
SmartCities projects run by governments all over the globe. - Home
31. Tech Intensive Customers Those customers who have high need
for data transfer speed, optimum data security and constant service
support. They have usually a higher need for service quality and
hence are the ones who are willing to pay a premium price. Mid
Level Clients They are the ones who certainly need a healthy data
transfer rate, however the need for data security, and constant
customer support is not that high as compared to the tech intensive
customers. Stakes are usually lower, in terms of data security and
need for round-o-clock support. They have moderate willingness to
pay for such services. Tertiary Customers They form a segment which
require custom made products suitable for individual or classified
needs. Example: Table Lamps for the household segment that is LiFi
enabled. They want cheap, reliable and catchy products.
32. A Typical Business Opportunity - Possible Services, Assets
and Customer Segmentation
33. Apple is to launch future iPhones with LiFi capabilities, a
new technology that may end up replacing the widely-used Wi-Fi in
the future technology. Beginning with iOS 9.1 update, the operating
system's source code makes mention of "LiFi-Capability" alongside
declarations to other hardware and software capabilities.
Smartphones will soon be able to download traffic information from
traffic lights or a program guide from a television. In the future
via location based services, shops will transmit advertisements to
your phone as you pass by and bus schedule changes will be
transmitted to a screen at the stop. Smarter home appliances that
talk machine-to-machine (M2M) are already being extensively
researched, where LED lights on electronics function as LiFi access
34. To manufacture the components cheap enough to be able to
penetrate the household segment. To provide customized solutions
for segments like Furniture Stores, Hospitals (Devices &
Ambulances), Public Places (Based on agreement with government). To
design attractive and catchy products for kids segment, e.g. Table
Lamp LiFi Model. To build necessary strategic relations and create
sustainable complementary asset network.
35. For now, LiFi networks can, and will, provide the perfect
complement to todays RF infrastructure and further enhance mobile
communications. However, the spectrum crunch is coming, and unless
the new technologies take speed and present itself as a potential
alternative, the indoor and outdoor communications will be in sore
need of bolstering, given that the current rate of wireless data
growth is unceasing. The only solution to this is a high- speed,
bidirectional, fully mobile wireless network: i.e. a LiFi
