Free wifi(outernet)

  1. 1. Sarmad Abid 11i-0419
  2. 2.  WiFi (or Wi-Fi) is short for Wireless Fidelity. WiFi is a wireless networking technology that allows computers and other devices to communicate over a wireless signal  The same way a radio can tune into a radio station signal over the airwaves, your device can pick up a signal that connects it to the internet, thru the air. As a matter of fact, a WiFi signal is a high-frequency radio signal.
  3. 3.  The router is the key piece of equipment in a wireless network. Only the router is physically connected to the internet by an ethernet cable. The router then broadcasts the high- frequency radio signal which carries data to and from the internet  The adapter in whatever device you are using then picks up the signal and reads it from the router.
  4. 4.  One ambitious organization called the Media Development Investment Fund (MDIF) is launching a project known as the Outer-net which is to launch hundreds of miniature satellites into low Earth orbit by June 2015  Each satellite will broadcast the Internet to phones and computers giving billions of people across the globe free online access
  5. 5.  The company's plan is to launch hundreds of low-cost miniature satellites, known as cubesats, into low Earth orbit.  Each satellite will receive data from a network of ground stations across the globe.  Using a technique known as User Datagram Protocol (UDP) multitasking, which is the sharing of data between users on a network, Outernet will beam information to users.
  6. 6.  The company is asking for contributions to the project of any size, which will all be 100 percent tax-deductible.  MDIF has acknowledged that building such a network would not be cheap. Such satellites typically run $100,000 to $300,000 to build and launch.
  7. 7.  The Outernet team claim that only 60% of the world's population currently have access to the wealth of knowledge that can be found on the Internet. So there will be internet for all  Free of cost internet  Universally accessible  The project could provide unrestricted Internet access to countries where their web access is restricted, including China and North Korea
  8. 8.  By June of this year the Outernet project aims to begin the development of prototype satellites and deploying prototype satellites to test their technology and testing of long range WiFi multicasting  In September 2014 they will make a request to NASA to test their technology on the International Space Station . Transmission testing in flight-like environments
  9. 9. By early 2015 they intend to begin manufacturing and launching their satellites and testing of constellation operations By April 2015 Establish manufacturing process for hundreds of satellites The project will be completed in June 2015 and the company says that they will begin broadcasting the Outernet from space
