This document defines a secure Wi-Fi distribution network installed in the aircraft passenger cabin for passenger and crew use. Carry-on Portable Electronic Devices (PEDs) such as smart phones, tablets, and laptops may use this network to access public internet services provided on the aircraft.

ARINC 658 was prepared to recognize the expanding role of data communication technology and the evolutionary path forward starting from ACARS protocols, to ATN/OSI protocols, and eventually ATN/IPS protocols using highly secure networks. The ATN/IPS network will be implemented onboard an aircraft and in the ground infrastructure to support safety services, including Air Traffic Services (ATS) and Aeronautical Operational Control (AOC). As such it provides a so-called “roadmap” for the development of the aviation standards for ATN/IPS services. ATN/IPS standards will evolve in coming years and be coordinated with other international standards organizations such as ICAO, EUROCAE and RTCA.

The purpose of this document is to define a general purpose non-proprietary information exchange framework and protocol for the conduct of Internet Protocol based message traffic between aircraft and airline ground infrastructure. This standard is motivated by the vision to substantially simplify information processing management for airlines by eliminating multiple dissimilar implementations with a single universal system and thereby establishing a more economical environment.
