LiFi uses visible light communication (VLC) to transmit data wirelessly using light waves instead of radio waves. It provides higher speeds than WiFi, with download speeds up to 100Gbps for LiFi compared to 10Gbps for WiFi. LiFi is also more secure, provides non-line-of-sight communication, and has benefits like reduced costs due to using existing LED lighting infrastructure. While initial installation costs may be higher, LiFi systems can become cheaper than WiFi over time. LiFi has potential applications in dense urban environments, transportation, healthcare, and other industries.

4. 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.

7. 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.

11. 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.

12. 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

13. 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 using
Poly-Silicon

14. Other Factors
There are other relevant factors
which drives us to think of an
alternative technology altogether.

17. Internet is received in terms
of stream of bits of 1’s and
0’s.
Lamp Driver converts this
stream of bits into sequence
of signals to turn the LED on
and off at rapid rate

18. Unidirectional????
Special LEDs???
NO!!!

22. No
Line-of-
Sight?
Reflection
to the
rescue!!

23. ● Microcontroller forms the heart of
the LAMP Driver Circuit.
● It holds the software operating
system, network protocols.
● It provides remote maintenance
capability.

24. MCU = Micro Controller Unit

26. • Spectrum of visible light is
broader and 10000 times
higher than radio waves.
• It has been predicted
spectrum crunch in UK by
2020.

27. • 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.

28. 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.

30. WiFi LiFi

31. 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 a/b/g/n/ac/ad devices.

32. • Since LiFi makes use
of electricity of LED’s
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.

33. 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 doesn’t require routers.

34. • Dense Urban Environments – High Demand (Especially
Developing Nations)
• Underwater Communications
• Vehicles & Transportation
• Healthcare Mobility Services – Ambulance with Data Transfer
Abilities
• Aviation
• Data Security

35. • 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 can’t 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.

36. • 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.

39. Look at the DOWNLINK and UPLINK
data transfer speed.
IT’S SAME!!
Can you imagine that
with WiFi?
Not Yet I believe.

42. 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.

43. Installed base for LED more
than tripled within a span of
two years and is expected
to acquire
25%
of installed base share by 2020.

44. An industry expected
to grow by
82%
as per CAGR means serious business.

45. 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 can’t ignore it.
Can we?

46. If a business is developed over the LiFi technology, it’s 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 appliances Segment

47. 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.

48. A Typical Business Opportunity - Possible Services, Assets and Customer Segmentation

49. 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 points.

50. 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.

51. For now, LiFi networks can, and will, provide the perfect
complement to today’s 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 System.
