Forward Link
Multiple Ku-Band
Transponders
• One forward link signal per transponder
• A transponder will carry data
for multiple aircraft
• Aircraft receive the transponder
signal and accept data
addressed to it
• Multiple transponders may
be used in a region
• Each aircraft may
receive from multiple
transponders

Return Link
• Each aircraft is assigned to one transponder
• Multiple aircraft may share one transponder
using multiple access codes
Multiple Ku-Band

Broadband Connectivity to Aircraft
What will Broadband Connectivity accomplish for Aviation
Communications?
Broadband Connectivity will allow more and better communications
for passengers and airline companies which will result in increased
and better
- Security
- Efficiency
- Passenger Satisfaction
Broadband Connectivity to Aircraft
Why is Broadband Connectivity necessary?
Advanced aeronautical systems are producing – and relying on ever increasing amounts of data that are used to improve their
ease of use, effectiveness and efficiency.
Often at times it is necessary to communicate these data to external
entities in order to achieve the advantages that these advanced
systems bring.
These facts apply to all advanced systems including aircraft operation
and communications.
Broadband Connectivity to Aircraft
How is Broadband Connectivity better than the systems currently in use?
Broadband Connectivity allows more data to be transferred in a smaller
amount of time.
Broadband Connectivity allows better and more complete information to
be delivered.
 In flight equipment monitoring, telemetered to the ground, can flag potential
problems and permit provisioning of repair parts in advance of landing
leading to more efficient turn-around times.
Broadband Connectivity enables higher fidelity and advanced status
reporting that results in more comfortable and more efficient
operations.
 Weather information, including detailed maps, would lead to more
comfortable flights.
Broadband Connectivity to Aircraft
What are the potential applications of Broadband Connectivity?
 Enhanced on-board Equipment Status Reporting
 Improved Access to real time Weather Data, both En route and
Terminal
 Transfer of Updated Navigation Charts
 Airport and Airway Status Updates
 On-Board Video Surveillance, sent to the ground, for Improved
Security
 Video Tele-Medical Assistance for both Passengers and Crew
Broadband Connectivity to Aircraft
Broadband Connectivity to Aircraft will enable more secure,
more efficient and more comfortable flying by allowing
improved communications that will facilitate better flight
status information, improved maintenance, enhanced onboard security and improved crew and passenger
communication.
