Re: Information concerning studies leading recommendations and regulation for the in-flight use of consumer UWB devices on commercial (civilian) aircraft.

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.

Notice: This document has been prepared to assist the IEEE P802.15. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s).

What is the RTCA?

• 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

What is SC202?(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 2 - Study the in-flight use of emerging PED technologies, for example ultra-wideband devices or pico-cells for telephone use on board aircraft.

• Met in May; next meeting in July

RTCA SC202

• Had its first meeting last week in Washington DC to start work in two areas:

1. 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

2. In Phase 2 - Study the in-flight use of emerging PED technologies, for example ultra-wideband devices or pico-cells for telephone use on board aircraft.

If the UWB study does not begin until 2005, why worry now?

• 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

Possible impact on 802.15.3a

• As a result of studying the effect of consumer UWB devices on aircraft avionics systems, it is possible that recommendations will be made to the FCC to lower the UWB emissions mask in selected frequency bands

• Any late changes in the US regulation for UWB would be likely to delay UWB deployment

• Possible changes to the FCC emissions mask were mentioned in passing: should receive the attention of 802.15.3a
