Full Description

This document contains Minimum Aviation System Performance Standards (MASPS) for coexistence of Wireless Avionics Intra-Communication (WAIC) systems operating within the 4200-4400 MHz radio frequency band. The term WAIC refers to a broad class of onboard wireless communication systems intended to provide data links between various aircraft functions [1]. This document provides designers of WAIC systems with guidance on how to demonstrate coexistence of WAIC systems with aircraft systems installed on board other aircraft using the same radio frequency spectrum between 4200 MHz and 4400 MHz. These other aircraft systems are radio altimeters and other WAIC systems.
