1 ICAO Seminar on Aeronautical spectrum management (Cairo, 7 – 17 June 2006) ULTRA WIDE BAND TECHNOLOGY A THREAT OR NOT TO AVIATION ? (presented by Eurocontrol)

2 STATUS TG 1/8 CLOSED THE UWB QUESTION IN ITU Autumn 2005 Outcome: recommendation made however ultimate decision on UWB emission limits and regulation left with the State TG 3 (The European technical study group), reviewed this decision and put forward proposed European limits to ECC ECC consultation process –on general UWB applications closed on 24/12/05 –On GHz applications closed on 29/05/06 –Aviations (EUROCONTROL + Adm.) complained for radars, radio- altimeters and MLS Outcomes: 24/12/05 More stringent values in order to better protect primary radars

3 ECC versus aviation limits

4 So what is done/planned ? 1. Response to the consultation process 2. Testing of the 4 threatened services with real UWB signal - UK Radar tests -DFS radar tests -Eurocontrol/EC PULSERS 1 testing (emphasis should be on 9 GHz airport radar) 1 Pervasive Ultra Wideband Spectral Energy Radio Systems (PULSERS) – a European Industry/EC initiative

5 UWB Allowable Field strength vs Distance UK TESTING

6 DFS Testing Bosch provide UWB-radar (wall probing,..) simulators No testing with UWB-communication with are the to- morrow mass market Tested : PSR L an S bands, mode S, SSR Outcomes: L band PSR is the most vulnerable to UWB- radar interference

7 NEXT STEPS 1.Validation testing on the 4 affected systems, need cooperation with PULSERS 2.Participate in and influence ECC / TG3 closedown process as necessary
