Making GateFusion a Reality
What is Gatelink?
•
Terrestrial data communications providing wireless access to the
aircraft
–
•
Gatelink includes a set of industry standards focused on data
communications between an aircraft and a gate
–
–
•
Capable of larger uploads/downloads than traditional wireless
communications
WiFi commonplace at airports
Supports aircraft operational requirements
–
•
Began as a tethered solution, moved to infra-red, now Wi-Fi (802.11x)
More aircraft centric data makes ‘Sneaker-net’ less viable
New aircraft models incorporate Terminal Wireless LAN Units
(TWLU)
–

Gatelink Data:
• Flight Operations Quality Assurance (FOQA) • In Flight Entertainment (IFE) Content
• Flight Release Paperwork
• Electronic Flight Bag (EFB) Content
• Nav Database Updates
• Cabin System Updates
GateFusion Resolves Gatelink
Complexities
•
ARINC brings years of experience with Airport Wi-Fi, ground
networks, and common use services to solve the following
Gatelink challenges:
•
Global Technical Solution
– Consistent technical interface from airport-to-airport
•
Eliminates Bandwidth Limitations
– Data Delivery Service eliminates bandwidth variables between
aircraft and airline’s application host
•
Global Reach
– Single point of contact for fully-managed service worldwide
Wi-Fi and Wi-Max for Aviation
• ARINC has been involved with Wi-Fi standardization for
aviation for nearly 10 years
– Latest AEEC specification (822) fully addresses security,
authentication, and interoperability
• Wi-Max is a promising technology, and ARINC is
supporting efforts to address compatibility/security
issues for aviation
– Latest standard ratified by IEEE less than one year ago
– Communication products/standards require time to mature
– Advantages and disadvantages of either technology
• Bandwidth sharing
• Distance from transmitter

Airline Application Server
Gatelink Issue #2 – Bandwidth limitations
Gatelink Bandwidth on airport premise is Mbps
Mbps
Aircraft to app throughput in this
case is effectively in kbps
Airport A
Data throughput is limited to lowest circuit speed in the data path
kbps
Bandwidth between airport and
airline network can be minimal
Airline Application Server
Mbps
Airline Network
Bandwidth from airline network to app host is Mbps

GateFusion’s Global Reach
• ARINC has negotiated access with multiple airport
authorities
–
–
–
–
Americas, Europe, Asia
Technical terms are met and satisfied
Initial commercial terms are established
Negotiating T&Cs with Authorities
• Coverage negotiated per individual airline
requirements
• Preliminary agreements reached with 65 airports
• Expect several hundred airports by end of 2007
