2. The Outernet is a global networking project currently
under development by the Media Development
Investment Fund (MDIF), which is established in 1995.
The Outernet's goal is to provide free access to internet
data through Wi-Fi, made available effectively to all parts
of the world.

3.  Less than 40% of the global population has access to the
wealth of knowledge found on the Internet.
The price of data in many parts of the world continues to be
unaffordable for the majority of global citizens.
In some places, such as rural areas and remote regions, cell
towers and Internet cables simply don't exist.
The primary objective of the Outernet is to
bridge the global information divide.

4.  Outernet's Wi-Fi solution works by using hundreds of tiny 10cm
cube-shaped satellites called "cubesats“.
 Outernet consists of a constellation of low cost, miniature
satellites in Lower Earth Orbit.
 Each satellite receives data streams from a network of ground
stations and transmits that data in a continuous loop until new
content is received.

5. A CubeSat is a type of miniaturized satellite for space research
with a volume of exactly one liter (10 cm cube), has a mass of
1.33 kilograms.
Double or triple configurations are possible. In this case
allowable mass is 2 kg or 3 kg respectively.

6.  The standard 10×10×10 cm Cubesat is often called a 1U meaning
one unit.
 Cubesats such as “2U” Cubesat (20×10×10 cm) and “3U”
Cubesat (30×10×10 cm)can also be made.
 With their relatively small size, Cubesats could each be made and
launched for an estimated price of 40 lakh - 50 lakh.

7.  Cubesats are launched and deployed using a mechanism
called Poly-Pico satellite Orbit Deployer (P-POD).
 P-POD technique was also developed by California
Polytechnic State University (Cal Poly).
 P-PODs are mounted to a launch vehicle and carry Cubesats
into orbit, then deploy them after proper signal is received
from the launch vehicle.

System Segments

9.  Space Segment consists of 14 satellites evenly spaced at
a distance of 900km in circular equatorial orbit.
 All LEO satellites in orbits below 600km altitude will
come into range of the constellation
The user segment consist of clients who wish to use the
Outernet Service via their mobiles or tablets.

10.  This segment consists of several ground stations spread
around the equator of the earth.
 Due to constellation’s equatorial orbit, each of the
satellites will pass every ground station during every orbit.
 Three potential ground stations have already been
identified: Guiana Space Centre(South America), Broglio
Space Centre(Kenya) and Pusat Remote Sensing
(Malaysia).

12.  There are more computing devices in the world than people,
yet less than 40% of the global population has access to the
wealth of knowledge found on the internet.
 In some places, such as rural areas and remote regions, cell
towers and internet cables simply don’t exist.

13. It would allow users to bypass any internet censorship
policies
 Outernet's Wi-Fi would ideally benefit areas with no access
to Wi-Fi at all.
The network could also be used as a global notification
system during emergencies and natural disasters, when mobile
base stations and power grids go offline.
Less land and material consumed by not building multiple
ground stations.

14. Outernet's near-term goal is to provide the entire
world with broadcast data.
The long-term vision includes the addition of two-way
Internet access for everyone for free.

15. The Outernet, as envisioned, would be one-way-data
would flow from feeders to the satellites which
would broadcast to all below for free.
