Google funded following projects to fight against online barriers
|Digital Attack Map||
- 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.
- get link 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.
- will help people virtually visit those site.

- 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?
- 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.
- 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)
- 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

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
- 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.
Its source can be of two types
|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||Ionizing radiation|
|has relatively low energy and low frequency||relatively higher|
||Can do those damages.|
Observe following photo-From left to right: frequency increases and wavelength decreases.
|CDMA||869 – 890 MHz|
|GSM900||935 – 960 MHz|
|GSM1800||1805 – 1880 MHz|
|3G||2110 – 2170 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 source- so we need to setup more and more mobile towers to have good connectivity.
- 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.
|It is safer using a mobile from car because the car shields from the radiation.||Mobile phone generates more RF radiation to overcome the shielding of car and reach the tower. so infact, using phone while in car=more harmful.|
|mobile phone emits radiation only when you are talking with someone.||As long as mobile is “on” it automatically transmits Radio frequency signal to check (poll) the network with nearest tower. it doesn’t matter where you’re talking or not.|
|Mobile Base stations are dangerous and we should keep distance from it.||We need to keep distance from the ‘antenna’ of base station.At the ground level, the radiation intensity is much lesser than @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
- 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|
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.
|UVA||wavelength longest among 3||Majority of UV radiation coming to earth, is of this type.|
|UVB||medium||As Ozone layer depletes, more and more of this UVB light incoming. It 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. Artificial UVC lights used in food/medical/pharma industry to kill germs.|
- 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.
Nothing sci-tech but some fodder material:
