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.

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.

..in Feb 2016!!

..that means ideally!

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.

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

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

Other Factors There are other relevant factors

which drives us to think of an

alternative technology altogether.

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

Unidirectional????

Special LEDs???

NO!!!

No Line-of-Sight?

Reflection to the

rescue!!

● Microcontroller forms the heart of

the LAMP Driver Circuit.

● It holds the software operating

system, network protocols.

● It provides remote maintenance capability.

MCU = Micro Controller Unit

• Spectrum of visible light is

broader and 10000 times

higher than radio waves.

• It has been predicted

spectrum crunch in UK by

2020.

• 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.

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.

WiFi LiFi

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.

• 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.

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.

• Dense Urban Environments – High Demand (Especially

Developing Nations)

• Underwater Communications

• Vehicles & Transportation

• Healthcare Mobility Services – Ambulance with Data Transfer

Abilities

• Aviation

• Data Security

• 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.

• 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.

Look at the DOWNLINK and UPLINK

data transfer speed.

IT’S SAME!!

Can you imagine that

with WiFi? Not Yet I believe.

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.

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.

An industry expected

to grow by

82% as per CAGR means serious business.

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?

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

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.

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

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.

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.

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.
