Document Scope

This specification addresses the following types of IPv4-based connections between an aircraft on the ground and the airline’s network infrastructure:

• Connections based on IEEE 802.11 wireless LAN standards

• Connections using cellular technologies: 3G, Universal Mobile Telecommunications System (UMTS), 4G, and Long Term Evolution (LTE)

This specification does not address the following technologies, nor does it preclude their future addition based on market demand:

• Wired connections to the aircraft at the gate, e.g., powerline communications

• AeroMACS, an aviation implementation of IEEE 802.16e (WiMAX) that uses protected spectrum to carry safety communications

• 5G cellular

• IPv6

Elements necessary for interoperability in the radio and network layers are addressed while methods for application data transfer are out of scope. Measures to enhance cyber security are included and may go beyond basic interoperability.

It is not the intent of this document to specify a system’s implementation, define components, or imply an approach to such an implementation. Ultimately, it is up to suppliers, manufacturers, and end customers (i.e., airlines) to determine the requirements for, and acceptance of, products that comply with this specification. Manufacturers and suppliers are encouraged to exceed the features and functionality described by this specification to meet evolving market needs.

This document does not specify the form and fit of the airborne equipment, nor other physical and electrical characteristics. These are defined in ARINC Characteristics 763 and 763A.
