AMCP WGC/2-WP25, May 20011 Preserving the 5 GHz Aviation Band AMCP Working Group C Noordwijk, The Netherlands May 7-11, 2001 Mike Biggs, US FAA
AMCP WGC/2-WP25, May 20012 Threat: Loss of 5 GHz ARNS Band Likely loss of 5150-5250 MHz at WRC-03 5091-5150 MHz next target –Addressing MLS requirements in Europe –Opinion: Going to be difficult to make convincing case At best is Regional protection Aviation needs to consider fall-back position
AMCP WGC/2-WP25, May 20013 Other Inputs Currently no aviation fixed-service bands Programs ongoing to prevent Runway Incursion Desire for data-intensive services for pilots on/near airport surface –Commercial effort for terminal-area development via Wireless Airport Association AMSS/NGSS shows possibility of shared systems VHF Band congestion vs increased data requirements
AMCP WGC/2-WP25, May 20014 Proposal: In parallel to MLS work, begin aviation efforts to look at: Requirement for aviation fixed-service bands Airport area wireless LAN. Make it as flexible as possible: –Sensors to support runway incursion efforts? –Shared with public via P 3 scheme? Help with development costs/timetables –Extended coverage to support near-airport services (e.g., 10 nmi radius for certain 1-way or 2-way data link)?
AMCP WGC/2-WP25, May 20015 Way Forward FAA has tasked NASA to explore existing technologies –Clean sheet approach –Need user input as to requirements Outreach to user groups (IATA, AFC,WAA) Need interface with Eurocontrol Need input from AMCP Effort is time-critical if we want to use this effort to preserve spectrum at WRC-03
