Abstract:This document provides an overview of the newly initiated activities of the RTCA (Radio Technical Commission for Aeronautics) Special Committee 202 (SC202). Purpose:To provide information and to suggest that a technical liaison between 802.15 and RTCA SC202 may encourage the development of balanced rules and regulations for consumer UWB use on aircraft.

It functions as a Federal Advisory Committee to the FAA It develops consensus-based recommendations regarding –Communications, –Navigation, –Surveillance, and –Air traffic management (CNS/ATM) system issues Learn more about RTCA at http://www.rtca.org/about rtca.asp http://www.rtca.org/about rtca.asp

(RTCA Special Committee 202) Recently established at the request of the Federal Aviation Administration, To work in two areas: In Phase 1 – study in-flight use of wireless Personal Electronic Device (PED) technologies that currently exist specifically current generation cellular telephones, current technology wireless PDAs, and devices with IEEE 802.11a, IEEE 802.11b, and Bluetooth™ wireless network capabilities Phase 1 - develop test plans and documents will most likely be used to test UWB devices in Phase 2. Phase 2 - Study the in-flight use of emerging PED technologies, for example ultra-wideband devices and cellular pico-cells for telephone use on board aircraft. Met in May; next meeting in July

NASA Langley is/will be conducting UWB tests prior to the beginning of formal work in SC202 NASA Langley performed tests and released results last year This is an early opportunity to exchange information with NASA Langley on UWB and its interference effects
