Project WIN:
WIRELESS INTRANET

ABOUT
60% OF THE HUMAN RACE DOES NOT HAVE INTERNET
There’s no infrastructure
Communication
infrastructure isn’t
justified for communities
without a significant
economy
Data plans are expensive
Data plans cost over
$50/month in remote
areas, if even offered
WiFi devices are useless
WiFi-enabled devices,
donated through
organizations such as One
Laptop Per Child, are
relatively useless without
a wireless network
OUR SOLUTION: A WiFi-BASED INTRANET
Node hotspots
Store 16GB of resources and
link into the network via WiFi,
eliminating the need for the
global internet to access
resources
Hosted web apps
Nodes will provide
communication services such
as instant messaging and email
Solar-powered
Central
connection to
cellular network
Not limited by electricity
infrastructure, batterypowered at night for constant
connection. Affordable for a
subsistence farmer.
Hosted education
Educational resources such
as Wikipedia and Project
Gutenberg will be hosted on
the network
+1.7%
Increase in exports (10% adoption)
+1.1%
Increase in imports (10% adoption)
$3,703
Average GDP of developing nations
Sources: Brookings, UNCTAD
$227 BILLION
Projected increase in the world economy following a
10% increase in third-world internet access
REQUIREMENTS
Power
Nodes must be able to provide
at least 150mA at 3.3V
constantly on 10 hours of direct
sunlight per day
Integration
Microcontroller must be able to
host stored data over the network
at over 100kbps without any other
limiting factors
Uptime
The network must be self-healing,
properly adapting to a node
failing. Nodes must gracefully find
a new path on which to send data
to the required node in less than
five seconds (the total time spent
finding a new path is < 5s)
Durability
Nodes must be able to
withstand torrential downpour
and a 1m drop
Networking
Packets must traverse the network
through nodes at a rate of no less
than 100kbps
Affordability
The price must be affordable for a
low-income family - no more than
$25USD/node and no more than
$100USD/server

Verification: Range
Verification: Power Supply
Modularity
Interchangeable batteries
and solar panels allow node
to operate efficiently in any
climate
0.3%
Projected Downtime
8400mAh battery + 550mA PV panel
Charging Options
Charging options, such as
through car batteries or a
basic grid, allow nodes to
stay operational under heavy
cloud cover
Verification: Case
Modular space
Affordable mounting
Waterproofing lip
Adjustable antenna
Software
WEBPAGE
Educational resource hosted
indirectly over the network
