7

• SCOPE / Aspects not covered
• This report does not cover
• the impact of terrestrial networks on the GSM
  onboard aircraft system,
• any consideration of regulatory and operational
  aspects
• Any compatibility with the aircraft avionics.

8

• End-to-end Description of a system using the NCU
  solution

9

• IDENTIFICATION OF SCENARIOS
• Scenarios 1 and 2 cover the case where no onboard
  GSM system is present
• Scenarios 3 and 4 cover the onboard GSM system
  effects on the terrestrial system
• Scenarios 5 and 6 cover the onboard GSM system
  effects on the terrestrial system for multiple
  aircraft

10

• Simulation tools
• Manual link budget for point-to-point scenarios
• SEAMCAT for multipoint-to-point scenarios

11

• REFERENCE VALUES / Parameters
• Mobile stations (MS, UE)
• Base stations (BTS, NodeB)
• Both operators (real data) and standard
  parameters are part of the study

12

• Controversial issues items closed
• Systems to be taken into account and frequency
  bands
• Parameters including the power level, the
  sensitivity, the base station antenna patterns
• Interference criteria (C/I9dB)
• Hull attenuation
• Technology neutrality

13

• Controversial issues items open
