ACP Working Group F (frequency)

• 
  Rapporteur Steve Mitchell, UK NATS
• Responsible for the initial development of the
  draft ICAO Position for WRCs.
• Draft Position is reviewed by ANC, then sent to
  States for comments, reviewed again by the Air
  Navigation Commission and finally reviewed and
  adopted by Council, much the same as SARPs.
• Develops the draft overall ICAO frequency
  spectrum policy which covers all spectrum items
  not addressed in the WRC position.
• Policy is then finalized by the Air Navigation
  Commission and adopted by Council.
• Serves as a forum of aviation frequency spectrum
  experts to assist the ICAO Secretariat in
  developing material to support the common
  aviation position during the deliberations of the
  ITU-R study groups and CPM and of the regional
  telecommunication organizations.

  policy statements
• Edition 5 of Doc 9718, the Frequency Spectrum
  Handbook
• Development of numerous input contributions to
  ITU-R Study Groups in support of ICAO position
• Regional Preparatory Workshop for APAC in
  preparation for WRC-12

ACP WG-FWork Programme for 2010 - 2012

• Continue preparation for WRC-2012
• Continue development of input material for ICAO
  contributions to ITU-R Study groups and WRC
  preparatory meetings of Regional
  Telecommunication Organizations.
• Two Frequency Spectrum Workshops in the ICAO
  Regions in 2011. Objective
• provide a forum for aviation professionals
  designated by the States, responsible for the
  preparation of the WRC-12
• Main items at next WRC
• AI 1.3 (UAS)
• AI 1.4 (AM(R)S in 108-117.975, 960-1164 and 5GHz
  bands
• AI 1.7 (AMS(R)S access in the L band
• Interference issues and other items which may
  affect access to spectrum by Civil Aviation

ACP WG-F Programme Watchlist

• ACP monitors technical developments in the
  aviation industry in preparation for future
  action
• Future Communication Infrastructure
• Airport Surface AM(R)S (IEEE 802.16e)
• Future L-Band communication system (LDACS).
• Future AMS(R)S technologies/providers
• Unmanned Aircraft Systems
• Foreseen frequency spectrum requirements for
  remote control and sense-and-avoid functions.
• WAIC wireless aircraft intra- communication.
• Technical Standards, certification and licensing
  issues foreseen.
• Any Com/Nav/Sur development
• Ensure availability of adequate spectrum
  resources

ACP WG-FThe spectrum challenges ahead

• Overall share of spectrum used by aviation is 10
  15 of all available spectrum in the range 0
  15.7 GHz
• Pressure on spectrum increasing
• Main drivers
• Mobile Phone services
• Broadband wireless networking
• Many others
• High yield to State/government from leasing
  spectrum to commercial providers
• Administrative Incentive Pricing for Spectrum
• Philosophy Estimate the opportunity cost of
  denying alternative users access to the spectrum.
  Users of the spectrum then pay a license fee
  equal to this opportunity cost. The intention
  with AIP is to promote the best social and
  economic use of the spectrum resource.
• Growing concern that AIP may lead to severe
  safety implications when applied to aeronautical
  safety spectrum allocations.

8
ACP WG-FThe spectrum challenges ahead

• Safety Services (ARNS/AM(R)S/AMS(R)S), unpopular
  neighbours due to stringent access requirements
  (6dB
  safety margin, super primary)
• Old/Proven technologies used in aviation CNS
  systems, spectrum inefficient?
• Long lifespan and high cost of aircraft, avionics
  and ground infrastructure
• Technical or equipage SARPs normally not
  retroactive
• Recent aviation updates to the Table of Frequency
  Allocations in the ITU Radio Regulations have
  been for increased flexibility of existing
  allocations.

9
ACP WG-FThe spectrum challenges ahead

• One or two regions have spectrum congestion
  issues. A global or a regional challenge?
• Some arguments for a regional challenge
• NextGen and SESAR programmes define regional
  requirements in the two busiest regions only
• Cost with limited benefit in other regions?
• Strong demands within a single region for more
  efficient use of spectrum resource, due to
  pressures from non-aviation for access to
  existing aviation spectrum, less pressure in
  other regions
• Some arguments for a global challenge
• Due to interregional mobility, global
  interoperability is required
• Pressures on the spectrum resource are mounting
  in all regions, unlikely that aviation will get
  new spectrum to cater for new requirements
• Spectrum efficiency is a global responsibility
• Obviously a bit of both.

10
ACP WG-FThe spectrum challenges ahead

• Spectrum pressure as a driver for future
  technology development, as well as ATM
  requirements
• Mounting pressures on aviation safety spectrum
  allocations
• New systems tailored for new ATM requirements
  will be required
• Systems will have more stringent spectrum
  efficiency demands than before
• Systems will have to share spectrum with
  older
  technology, a challenge on several levels
• Older technology will have to be phased out.
• To date, global agreement on technology updates
  or replacements has always been difficult. Can
  this be changed? How?

11
ACP WG-FThe spectrum challenges ahead

• A paradigm shift needed?
• At the 37th Assembly, a common European paper
  suggested that a detailed spectrum and technology
  roadmap needs to be developed on a global level
  in preparation for the 12th Air Navigation
  Conference
• Limited progress to date within the Region in
  identifying new required future technology
  enablers, in spite of a large budget internal
  programme
• The Assembly agreed, and noted the following
• Work on identification of global CNS concepts is
  already included in the current radio frequency
  spectrum strategy and NextGen/SESAR work
  programme, however it could positively benefit
  from a stronger linkage to a long term global CNS
  implementation plan. The proposed 2012 twelfth
  Air Navigation Conference should develop a
  roadmap for CNS equipage transitions to support
  the spectrum strategy.
• No budget requirements were identified
