Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title:RTCA May Meeting Date Submitted: 11 May 2003 Source: Bob Huang Company:Sony Electronics Address: One Sony Drive T1-5, Park Ridge, NJ 07656 USA Voice: 201-358-4409 FAX:201-930-6397 E-Mail: robert.huang@am.sony.com 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.

2. Overview of the First Meeting of RTCA SC202 Bob Huang, Sony Electronics

3. 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 Bob Huang, Sony Electronics

4. 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 Bob Huang, Sony Electronics

5. RTCA SC202 • Had its first meeting last week in Washington DC to start 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 • 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. Bob Huang, Sony Electronics

6. RTCA SC202 • Target dates • Phase 1 (looking at existing wireless devices) • Started: May 2003 • To finish: January 2004 • In Phase 2 – • To begin after completion of Phase 1 • To finish: October 2005 Bob Huang, Sony Electronics

7. RTCA SC202 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 Bob Huang, Sony Electronics

8. RTCA SC202 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 Bob Huang, Sony Electronics

9. RTCA SC202 Meeting attendees • Aviation industry: ⃘ Regulators ⃘ Airlines ⃘ Air transport ⃘ Manufacturers: airframe, avionics, entertainment sys ⃘ Operators (pilots) • Wireless carriers and handset manufacturer • CE industry • PC industry • UWB technology developer Bob Huang, Sony Electronics
