Broadband- Broad Definition
Generally, Broadband describes
high speed, high capacity data
communication making use of
DSL, Cable Modem, Ethernet,
Fixed Wireless Access, Optical
Fiber, W-LAN, V-SAT etc.
There is no specific international
definition for the Broadband
though there is a common
understanding among developed
and developing countries that it
should be more than 2MBPS.
Broadband in India
As per Broadband Policy 2004 & GoI notification dated 18/07/2013, Broadband in India is defined as: Broadband is an Always-On data
connection that is able to support interactive services including Internet access and has the capability of the minimum download speed of 512 kbps to an individual subscriber from the point of presence (POP) of the service provider intending to provide Broadband service.
In INDIA, Total Broadband (> 512 Kbps) subscription is 58.00 million at the end of February, 2014. Out of which, wired broadband subscription is 14.80 million and wireless broadband subscription is 43.20 million.

Market Status of DSL Technology
• DSL is the #1 Broadband Choice in the World with
over 65% marketshare and more than 200 million
users
• DSL is available in every region of the world, and
ADSL owns the majority of the market though VDSL
and ADSL2plus are gaining ground
• DSL is capable of providing up to 100 Mbp, and
supports voice, video and data.
(ii) Cable TV Networks for broadband access
– Broadband over cable TV accounts for 74% of total connections in US, and 55% in Canada. Speed upto 20 mbps.
– 55 million cable homes in India, but infrastructure can not support bi-directional communication and requires upgrade which is costly
– Regulatory environment via Unified License of Digital Addressable CATV, allows this with few operators already doing so.
– To start with Cable TV network which is uni-directional can be used for downloading, the uplink to be conventional narrow band like dialup/ ISDN/ RADIO

–Fiber To The Home (FTTH) – Fibre in last mile to deliver converged services 100 MBPS
–Hybrid Fiber Coaxial (HFC) – by Cable TV operators
–GPON (Gigabit - Passive Optical Network) – triple play over TDM
(No limitation of distance or throughput speeds)
(up to 2.5 Gbps downstream rate and a greater distance from a central office (20 to 40 kilometers) Government of India has approved the setting up of National Optical Fiber Network (NOFN) on 25/10/211 through a new PSU BBNL to provide connectivity to 2,50,000 Gram Panchayats.
–Use of existing domestic power connections for sending data
–Throughput in the range of 1 MHz (4 – 6 Mbps)
–Ideal for rural areas where telecom / cable TV infrastructure may not be there
–IIIT Allahabad has undertaken a project in co-operation with Corinex Communications Canada to implement a prototype of BPL for University campus and nearby villages.
iv) Broadband over Powerline (BPL) Technologies
In year 2000, 189 countries came together to
discuss global challenges facing us.
They came up with 8 Millennium Development
Goals to be achieved by 2015.
Millennium Development Goals (MDGs)
Broadband Commission for Digital
Development
In May 2010, ITU and UNESCO, got concerned about
the time lines of implementing MDGs.
5 years only to 2015.
Will all the countries have delivered on their promises?
This led to the formation of Broadband commission for
Digital Development.
How to speed MDG Realization
Broadband is the answer!
Embrace a common leadership vision that has profound implications for the accelerated achievement of the millennium Development Goals (MDGs) by the internationally-agreed deadline of 2015
“Broadband Inclusion for All”
New York, September 19, 2010
MDG 1: Reducing poverty in the Information Age
CALL IT INFORMATION POVERTY:
1.4 billion people still lived on USD 1.25 or less per day.
10 million people still die annually of hunger
Present trends in rising food prices and the global economic crisis have
pushed at least 90 million more back into poverty
Due to unavailability of data communication infrastructure, individuals
and communities denied access to knowhow or market price data to
sell their produce which can reduce poverty.
Broadband impact on Economy

Source: World Bank
The World Bank (2009)
estimates that every 10%
increase in access to
broadband results in
1.38% growth in Gross
Domestic Product (GDP)
for developing countries. In
India, broadband has
already generated nearly 9
million direct and indirect
jobs.
MDG 2: Seventy million children still in need of UPE
70 million children do not enjoy a
primary school education.
Broadband networks can deliver
education interactivity & economically.
Online education is easing the
resource bottleneck in training
teachers;
To meet MDG-2, additional teachers
is being trained online in African
Countries.
In India, Governments and NGOs are
providing schools with PCs and
Internet connectivity to foster primary
education.
GOI is also focusing on National
Knowledge Network for connecting
colleges and universities to high
speed Internet.
MDG 3: Can broadband empower women?
Poverty is not just a devastating problem worldwide, it is also a disempowering
one.
Women are disproportionately represented in vulnerable or insecure
employment.
It’s here that telecoms – and in the future, broadband – could be one critical tool
in empowerment, as one towering role model shows: the GRAMEEN social
business concept in Bangladesh. 400,000 village entrepreneurs – the vast
majority of whom are so-called Village Phone Ladies – have been created
through this initiative.
Closing the mobile gender gap and bringing 600 million more women
online could increase global GDP by $13-18 billion.
MDG 4: Child health – broadband’s most important challenge?
Bringing child mortality down by two-thirds from 1990 to 2015 is the focus of the UN’s 4th MDG.
Major causes of child mortality – malnutrition, pneumonia, malaria, diarrhea, measles, HIV/AIDS, tetanus – remain treatable, but communities lack resources & knowledge to treat them.
WHO estimated a worldwide shortage of 4.3 million medical professionals
TELEMEDICINE : Only one computer, a scanner & a camera can transform into a hospital but the biggest need is broadband, which would allow doctors to share images and diagnose patients hundreds of miles away using video-conferencing.
Kenya and Rwanda, are already beginning to prioritize broadband as a platform for future health service delivery.
MDG 5: maternal health
In Africa and South Asia, under half of all births are attended by a midwife & complications during pregnancy and childbirth remain the most frequent cause of death for women.
Lack of access to health services is particularly acute for women in remote rural areas.
High-speed Internet enables health workers outside major centres to receive quality training and exchange experiences and information through video-conferencing, interactive discussion forums
Nigeria is linking 40 health centres to provide midwives with live training via video-conferencing.
Broadband services can give women easier access to information on family planning, hygiene and other reproductive health issues.
Rwanda, in 2009 spectacularly cut the annual maternal death toll from 2,875 to 224, is in no doubt about the health benefits of broadband.
MDG 6: Combatting HIV/AIDS, malaria and other
diseases HIV/AIDS, tuberculosis (TB) and
malaria kill more than four
million people every year, while 1
billion people suffer from
elephantiasis.
Success in combating these
diseases often rests on persuading
people to take simple low-tech
preventive measures, such as using
condoms or insecticide-treated
bednets.
Personalized risk assessments for HIV/AIDS through interactive online programs. Many
people may find it easier to answer questions posed by a computer than talk face to face
about sensitive subjects like sex;
Interactive online training and refresher courses for health workers, including video
conferencing;
Using images from India’s remote sensing satellites, the Malaria Research Centre in New
Delhi mapped areas where a particular malaria-carrying mosquito was likely to be found,
based on breeding and lifecycle patterns. These areas could then be targeted for control
measures.
MDG 7: Using broadband to ensure environmental
sustainability
The MDG on ensuring environmental sustainability spans a wide range of
targets, from the provision of safe drinking water and basic sanitation facilities
to reducing biodiversity loss and improving the lives of slum dwellers.
Combined with GPS-enabled mobile phones, they can support emergency
communications and medical assistance when disaster strikes.
Broadband-powered GPS-based applications can also help monitor
environmental abuses in real-time, such as illegal logging or ships illegally
washing out their tankers at sea (according to technology developed by the
firm Astrium), and transmit that information to regulatory authorities and
advocacy groups.
Internet and broadband can help in reducing emissions by 25 percent as
people can use mobile, teleconferencing and telecommuting and e-
commerce facilities. All these will help in saving lot of CO2 emissions.
MDG 8: Broadband empowers partnerships for development
Millennium Development Goal 8 on partnerships for development includes a specific target on
extending the benefits of new technologies, including information and communication
technologies (ICTs), in cooperation with the private sector. While the phenomenal growth of
mobile telephony in the developing world has transformed access to basic connectivity, the
‘digital divide’ remains enormous, especially where the Internet and broadband are concerned.
While a quarter of the world’s population now uses the Internet, in the very poorest countries, that
proportion is just two per cent. The ITU‟s „Connect the World‟ campaign aims to narrow the
„digital divide‟ by connecting all communities by 2015, the MDG target date, and by
ensuring half the world‟s population has access to broadband services. In developing
countries, and more remote areas of industrialized nations, this is likely to be achieved largely
through new wireless mobile broadband technologies such as WiMAX, which already serves over
twenty low- and middle-income countries.
Broadband networks can also help with other targets within MDG 8, such as addressing
the special needs of landlocked and small island developing countries.
Similarly, distance working or teleworking enabled by broadband can help in advancing another
MDG 8 target, to develop strategies for ‘decent and productive work for youth’. However, the
greatest contribution of broadband towards achieving the MDGs may be its catalytic role in
empowering people by giving them both knowledge and a voice in the public arena.
Final Remark The benefits of new technologies, especially ICTs, should be
made available by government in cooperation with the private
sector to meet the objectives of MDG in the country.
Broadband networks may even pay for themselves, due to
savings made in delivering services. In Australia, for example, it
has been estimated that cost savings in healthcare alone could
pay for the country’s National Broadband Network twice over.
For developing countries, the solution is likely to be found in
mobile broadband — using a mobile phone, of which there are
now some five billion worldwide, to connect to the information
society. By improving education, medical services, trade and
more, broadband Internet access can make a tremendous
difference. High-speed networks can lead to high-speed growth.
