Agenda Item xx: / XxxStatus of Efforts to Obtain Radio Frequency Spectrum for Wireless Avionics Intra Communications (WAIC)
(Aerospace Vehicle Systems Institute)
SUMMARYThis paper provides the status of future Agenda Item proposals under Agenda Item 8.2 regarding Wireless Avionics Intra-Communications. It also provides the proposals in the Annex.
ACTION
To request that ICAO support the efforts to obtain an Agenda Item for the 2015/16 World Radio Conference, particularly to request ICAO Working Group F to forward to the ACP its recommendation that ICAO include in its position for WRC-12 Agenda Items its support for an Agenda Item to study and make necessary changes to the radio regulations for WAIC applications if necessary.
1.INTRODUCTION
It is anticipated there will be numerous proposals at the 2012 World Radio Conference under Agenda Item 8.2, Future Conference Agenda Items. This Agenda Item is responsible for future World Radio Conference efforts to change the radio regulations to generally obtain additional radio frequency spectrum for various types of Services and applications. One important proposal under Agenda Item 8.2 specifically impacting aviation will be to consider spectrum requirements and possible regulatory actions, including allocations, to support wireless avionics intra-communications (WAIC) systems.
This contribution is intended to inform ICAO WG-F of Agenda Item 8.2 proposals on the WAIC topic and to request that ICAO add to its position, for WRC-12, specific support for an Agenda Item for WAIC systems.
1.1RECENTDEVELOPMENTSREGARDINGAGENDAITEM 8.2
Several Administrations have submitted proposals to their respective regional organizations supporting a future Agenda Item to study and possibly change the radio regulations to permit the use of WAIC systems. These proposals are discussed below and are provided in the Annex to this document.
2.SPECIFIC PROPOSALS
The Annex to this document provides the Administration proposals to date. Contributions by Brazil, Germany, New Zealand and the United States have been finalized. There is at least one proposal before CITEL, CEPT, and the APT. Although there are differences in the Resolutions, it is anticipated that the differences can be overcome.
2.1ACTION BY THE MEETING
The Aerospace Vehicles Systems Institute members request Working Group F to forward to the ACP a recommendation supporting a WRC-15/16 Agenda Item on Wireless Avionics Intra-Communications; and to include such support into the ICAO position for WRC-12. Proposed language is provided below:
WRC-12 Agenda Item 8.2
Agenda Item Title:
To recommend to the Council items for inclusion in the agenda for the next WRC, and to give its views on the preliminary agenda for the subsequent conference and on possible agenda items for future conferences, taking into account Resolution 806 (WRC-07).
Discussion:
The aerospace industry is developing new commercial aircraft to provide airlines and the flying public more cost-efficient, safe, and reliable air transportation. One important way of accomplishing these aims is to reduce aircraft weight while providing multiple and redundant methods to transmit safety-related information within and on an aircraft. The utilization of wireless technologies can accomplish these goals while providing environmental benefits and cost savings to manufacturers and operators.
Installed Wireless Avionics Intra-Communications (WAIC) systems are one way to derive these benefits. WAIC systems consist of radiocommunications between two or more transmitters and receivers on a single aircraft. Both the transmitter and receiver are integrated with or installed on the aircraft. In all cases, communication is part of a closed, exclusive network required for aircraft operation. WAIC systems will not provide air-to-ground or air-to-air communications. WAIC systems will be limited to safety and regularity-of-flight related applications.
New Report ITU-R M. 2197 provides findings on the technical characteristics and operational requirements of WAIC systems for a single aircraft. Current aeronautical services allocations may not be sufficient to permit the introduction of WAIC systems due to the anticipated WAIC bandwidth requirements.
Therefore, ICAO supports a WRC-15 agenda item to conduct studies and take appropriate regulatory action to accommodate WAIC systems.
ICAO Position:
To support a future WRC-15 Agenda Item to make necessary regulatory changes to the ITU-R Radio Regulations for Wireless Avionics Intra-Communications (WAIC) systems.

DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE
Agenda Item 8.2: to recommend to the Council items for inclusion in the agenda for the next WRC, and to give its views on the preliminary agenda for the subsequent conference and on possible agenda items for future conferences, taking into account Resolution 806 (WRC 07).
Introduction
The aerospace industry is developing the future generation of commercial aircraft to provide airlines and the flying public more cost-efficient, safe, and reliable aircraft. One important way of accomplishing these aims is to reduce aircraft weight while providing multiple and redundant methods to transmit information on an aircraft. Wireless technologies can be employed to accomplish these goals while also providing environmental benefits and cost savings to manufacturers and operators.
Installed Wireless Avionics Intra-Communications (WAIC) systems are one way to derive these benefits. WAIC systems consist of radiocommunications between two or more transmitters and receivers on a single aircraft. Both the transmitter and receiver will be integrated with or installed on the aircraft. In all cases, communication is part of a closed, exclusive network required for aircraft operation. WAIC systems will not provide air-to-ground or air-to-air communications, and will only be used for safety-related applications.
ITU-R Working Party 5B has developed a Draft New Report (ITU-R M.[WAIC], Document SG05/212) that provides findings on the technical characteristics and operational requirements of WAIC systems for a single aircraft.
Because WAIC systems are intended to improve the safety and regularity of flight of an aircraft, the International Civil Aviation Organization (ICAO) has indicated that WAIC systems should operate in a safety service allocation, such asallocations for the Aeronautical Mobile (Route) Service,AM(R)S, or another service with similar regulatory status. However, because of the ICAO recommendation and anticipated WAIC bandwidth requirements, existing AM(R)S spectrum allocations may not be sufficient to permit the introduction of WAIC systems and additional allocations may be required.
A resolution will be required to set out requirements for compatibility and coexistence studies since WAIC systems will be required to share bands currently used by other systems as well as identifying any requirements for a regulatory framework to facilitate the implementation of WAIC systems on-board aircraft. Particular regard will need to be given in these studies to the role of WAIC systems in supporting safety and regularity of flight requirements. The resolution will also invite ICAO to participate in the ITU-R studies.
New Zealand proposes a WRC-15 agenda item on WAIC that would instruct the ITU-R to conduct the appropriate studies, to bring the matter to the attention of ICAO and for WRC-15 to take the appropriate regulatory action to satisfy the spectrum requirements of WAIC systems and to provide the appropriate regulatory framework for the implementation of WAIC systems on-board aircraft.

Because WAIC systems are intended to improve the safety and regularity of flight of an aircraft, the International Civil Aviation Organization (ICAO) has indicated that WAIC systems should operate in a safety service allocation, which could include the Aeronautical Mobile (Route) Service or another service with similar regulatory status.
Because of the ICAO recommendation and anticipated WAIC bandwidth requirements, the Brazil believes that current AM(R)S spectrum allocations may not be sufficient to permit the introduction of WAIC systems. Accordingly, a WRC-15 agenda item is sought to conduct studies and take appropriate regulatory action to accommodate WAIC systems.
Therefore, the Brazil is proposing a new item for the preliminary agenda for the next World Radiocommunication Conference together with a draft resolution as shown in the attachment.
