  1. GSM On-Board Aircraft Presented By John Mettrop Directorate of Airspace Policy Surveillance & Spectrum Management

  2. What Is GSM On-Board Aircraft • Allows the use of mobile phones on board aircraft • Consists of • Noise floor lifter • GSM Pico-cell • Satellite communications link

  3. How Does it Work? BTS = Base Transceiver Station NCU = Network Control Unit AGS = Aircraft GSM Server

  4. Bands Controlled • Connectivity: • 1710-1785 MHz and 1805-1880 MHz (GSM1800) • Control: • 876-915 MHz and 921-960 MHz (GSM900 including GSM-R) • 1710-1785 MHz and 1805-1880 MHz (GSM1800) • 1920-1980 MHz and 2110-2170 MHz (UMTS UTRA- FDD 2GHz) • Future Control: • IMT extension bands

  5. History • First brought to ICAO’s attention in 2004 • Sept 2006, FMG recommend delay of approval until all issues are resolved • Dec 2006 • EANPG adopt FMG recommendation • State letter issued by ICAO Paris office • ECC decision on GSM on-board aircraft • Qantas aircraft starts flight trials • June 2007 Airbus A318 tale number MSN 3009 approved for operational trials in France

  6. Issues Identified (1) • Technical • Aeronautical • Interference to On-Board Radio Systems • Effect of Failure Modes on PSU • Need for the Jammer to be turned on during Take of and Landing • Radio Regulatory • Protection of Ground network • Applicability over countries and control of the units

  7. Issues Identified (2) • Operational • When will the phones have to be switched off • How this can be ensured through airline procedures for announcements etc • Applicability between different fleets and aircraft in fleets • Identification of different types of phones • Interference with/attention to safety messages

  8. Issues Identified (3) • Human Factors • Air Rage • Passengers who do not want to hear others using phones • Those who want to use their phones but cannot • Understanding differences in usage according to aircraft/airline/region • Turning phones off during take-off and landing

  9. Issues Identified (4) • Others • Applicability in Europe of EU ruling on roaming charges • Implication for other systems

  10. Where are We Now? • 1 Air France Aircraft fitted but not flying • 1 Qantas aircraft fitted and flying • Positive feedback from Qantas trial • Interest from a number of other airlines • Emirates • Ryanair • Etc • European Commission to hold a Workshop on the issue (3/10/07)
