Operational Communication

  1. 1. Connectivity 101 WAEA Technology Committee Single Focus Workshop 25 March 2010
  2. 2. Passenger connectivity: a false dawn? First ground to air telephone call (1920) :  radio takes off On August 19, 1920, Sir Samuel Instone, chairman of the Instone Air Line was able to have a telephone conversation by wireless radio between his home in London and a passenger on board on of his Vickers aeroplanes en route to Paris. This is thought to have been the first radio telephone call to an aircraft in flight. Another world first for Instone Air Lines………
  3. 3. A Brief History of Passenger Connectivity <ul><li>Before mid 1980s there was none. </li></ul><ul><li>The Connectivity market has evolved entirely in last 25 years: </li></ul><ul><li>1984 – first telephone system </li></ul><ul><li>1987 – first satellite telephone calls </li></ul><ul><li>1992 – first news and sports ticker </li></ul><ul><li>1993 – first fax </li></ul><ul><li>1996 – first live television </li></ul><ul><li>2001 – first e-mail </li></ul><ul><li>2002 – first broadband connectivity </li></ul><ul><li>2003 – first cabin wi-fi implementation </li></ul><ul><li>2005 – first GSM voice and SMS system </li></ul><ul><li>2006 – first GPRS mobile data system </li></ul>

  10. 10. Radio and Satellite Transmission Satellite (Ground) Station Radio (Base) Station Satellite Up link Forward link Return link Down link All elements of each system may vary: frequencies used, data rates, type of satellite, orbit, range of transmission, aircraft equipment etc., etc . Radio Transmission Satellite Transmission
