This specification provides the functional and protocol interface definition based on IEEE 802.11 technologies. Other wireless technologies are possible for this link, but the minimum standard for aircraft to airport wireless communication is based on IEEE 802.11. This document neither advocates, nor does it preclude, the use of other technologies. They may be added in future versions of this standard as the airlines deem them viable.

It is not the intent of this document specify a systems implementation, define components, or even imply an approach to such an implementation. However, given the availability of commonly available offthe- shelf technology to implement Local Area Network (LAN) functions, it would be fairly easy to reach such a conclusion. Ultimately, it is up to suppliers, manufacturers, and end customers (i.e., airlines) to determine the acceptance of products that comply with this specification.
