to nearest police control room. Then police can track the women based on her mobile
location- send nearby PCR van etc.
Pilot project in Rajasthan.
financed by Nirbhaya fund
but What is Nirbhaya fund?
In 2013’s budget, Chindu came up with two new initiatives for women
1. all India bank for women
2. Nirbhaya fund. (Named after Delhi rape victim “Nirbhaya)
This Nirbhaya fund has 1000 crore rupees- to support women centric projects by government and
NGOs.

Only 1/3rd of Indian internet users are women. Google India came up with new project to get 50
million Indian women online by the end of 2014.
How?
1. Via a new website “hwgo.com“. This website will provide very basics of the Internet,
special content for women like childcare, cooking recipes, household management etc .
2. Available in Hindi + English. (Similarly, Intel designed a mobile app “easy step” to
promote digital literacy)
3. Toll free helpline number – where women can call and get free answers about
internet/computer. (1800 41 999 77)
4. A pilot project in Rajasthan to train computer-net surfing to 1 lakh women.
Benefits:



New opportunity for women to get education, freedom of expression and self-esteem.
Ultimately
Less MMR and IMR
Higher GDP and HDI
#4: Google to defend freedom of expression
Google funded following projects to fight against online barriers

wearable backpack with a camera installed at the top
Camera has 15 lenses, takes picture every 2.5 seconds. The images are stiched together
with software= you get a 360 degree view of the location.
For streetviews (under google maps) they mount this camera on top of a car.
but @certain places like ancient monuments or natural sites, the car cannot go. and
person has to take this camera on foot.
why in news? Because Google India and the Archaeological Survey of India (ASI)
announced partnership to create 360-degree online imagery of 100 most important
heritage
including Taj Mahal, Khajuraho, Qutub Minar, Humayun’s Tomb and Ajanta and Ellora
caves.

#1: Gecko: Bluetooth device



Gecko is a Bluetooth device- size just little bigger than a coin. by Banglore based startup
company.
it also has an accelerometer sensor – to detect motion.
You can pair it with an apple or android phone/device.
ok but what’s the use?
1. Since it can detect motion- you put it in the doorknob- everytime someone opens door,
it’ll notify you on phone. If someone opens door at odd hours- say 2AM, it can make
your phone raise the burglar alarm.
2. similarly can be put in a pillbox- to ensure the person doesn’t forget to take medicine. (if
he forgets=pillbox doesn’t move=gecko sends remainder via phone)
3. you can even pair it with a camera- once you can get in the frame, wave your arm and
Gecko will trigger the camera to shoot photo
Why in news? because Apple’s co-founder Steve Wozniak gave funding.

#1: EMF radiation limit
DoT (Department of Telecom) panel has recommended 10 lakh fine if cell tower violates EMF
(electro magnetic field) radiation limits. (0.45 watts per sq metre)
More background news covered in an earlier article: click me
Let’s check the theory
Electromagnetic field (EMF)



as the name suggests: Electrical field + Magnetic Field= Electromagnetic field (EMF)
EMF is created when electric and magnetic waves travel to space together.
for example: electricity supply, radio waves from TV, radio devices, medical devices
mobile phones, radar and satellite communications.





EMF strength is measured in units watt per square meter(W/m2).
EMF radiation weakens very quickly as we move away from the source / antenna.
EMF strength is inversely proportional to the square of the distance from the source.
e.g. when distance from antenna doubles (2x) the EMF strength is reduced to (1/4)th
Similarly when distance 3times (3x), strength reduced to 1/9th.
Electromagnetic Radiation (EMR)
Its source can be of two types
natural
manmade
UV, visible light radio, TV, mobile phones etc.
we can further classify electromagnetic radiation based on can they ionize (and hence damage)
biological molecules?
Non Ionizing radiation
1. mobile handsets and antenna
2. radiation from visible light
3. infra-red radiation
Ionizing radiation
has relatively low energy and low frequency
 can’t break chemical bonds in body cells.
 can’t cause ionization of atoms and molecules.
 can’t damage DNA
relatively higher
1. X-ray radiation
2. gamma ray radiations
Can do those damages.
Electromagnetic spectrum
Observe following photo-From left to right: frequency increases and wavelength decreases.
Mobile Frequencies
mobile handset frequency
CDMA
869 – 890 MHz
GSM900
935 – 960 MHz
GSM1800
1805 – 1880 MHz
3G
2110 – 2170 MHz
4G
2300-2400 MHz
Observe frequency increases with new technology. Meaning wavelength must decrease.
Speaking of mobile phones




A mobile phone is two way radio.
It contains a transmitter and a receiver.
It emits electromagnetic radiation to exchange information with nearest base station.
but the strength of electromagnetic field decreases rapidly as we move away from sourceso we need to setup more and more mobile towers to have good connectivity.
Specific Absorption Rate (SAR)





It is the Rate at which Radio Frequency energy is absorbed in the human body
Unit of SAR = watts per kilo gram (W/kg) of tissue.
Every model of mobile handset has specific SAR value.
SAR Limit in India: 1.6 w/kg (effective from Sep.2012)
SAR matter falls under Department of Telecom.

fact
It is safer using a mobile from Mobile phone generates more RF radiation to overcome the
car because the car shields from shielding of car and reach the tower. so infact, using phone

while in car=more harmful.
mobile phone emits radiation As long as mobile is “on” it automatically transmits Radio

it doesn’t matter where you’re talking or not.
Mobile Base stations are
We need to keep distance from the ‘antenna’ of base station.At
dangerous and we should keep the ground level, the radiation intensity is much lesser than
distance from it.
@Antenna.


Metal & water are good conductors of radio waves so avoid using a mobile phone while
wearing metal-framed glasses or having wet hair
People having active medical implants should preferably keep the cell phone at least 15
cm away from the implant
Mobile towers- radiation limits


for mobile phones, Telecom department has prescribed SAR limits (1.6 w/kg)
similarly for Mobile towers, Telecom department has prescribed EMF radiation limits:
Nation EMF limit for mobile towers
India 0.45 watt/m2
China 0.9 watt/m2
Italy 0.1 watt/m2
Even Italians are more conscious about mobile tower radiation than India/China.


Anyways, if a mobile tower operator doesn’t comply with this limit, he’ll have to pay 10
lakh rupees fine per tower.
Telecommunications Engineering Centre (TEC) under Department of Telecom measures
these radiation levels.
UV radiation: three types


Ultra violate light (UV) has three subtypes based on their wavelength
Shorter the wavelength=more dangerous for body.
wavelength
Majority of UV radiation coming to earth, is of this type.
longest among 3
As Ozone layer depletes, more and more of this UVB light incoming. It
UVB medium
cannot penetrate beyond skin layer. Hence does all its damage to skin
itself e.g. tanning, burning, skin cancer.
UVC shortest among 3 but doesn’t reach earth’s surface. Most damaging- upto cell’s DNA.
UVA
Artificial UVC lights used in food/medical/pharma industry to kill germs.
#2: Preferential market access (PMA) policy





By Department of Electronics and IT (DEITY)
PMA policy makes it mandatory for the government and private companies to procure a
certain percentage of its requirements from desi manufacturers.
This was opposed by American companies including Apple.
Now government revising this policy to give some exemption to private companies
And limit to the scope of PMA policy to only the supply of electronic and telecom
equipment that has security implications.
#3: IT Potential in Africa
Nothing sci-tech but some fodder material:
Scope of Indian IT Companies in Africa because of following reasons:
1. Most of the African countries are seeing political stability and better economic growth
than ever before.
2. Indian companies can create digital infrastructure for in e-governance, e-banking, elearning- especially for maths+science.
3. IIT Delhi actively involved in the training, particularly vocational training and training of
teachers in some African countries.
4. Nearly 30% Of Africa’s demand for CRT, picture tubes, inverters, radios, sound
equipment, medical equipment, etc. is met from India imports.
5. Indian government setting up IT parks and other ICT related activities in a number of
African countries like Ethiopia, Senegal, Mozambique, Rwanda and Tanzania.
