UK Ultra Wide Band (UWB) Compatibility Study UWB Compatibility Study CEPT PT SE24 CEPT PT SE24 UWB Study To investigate the interference potential of various Pulsed UWB technology on existing and planned services Laboratory measurements and theoretical calculations. UWB Interference and victim receiver bandwidth Noise - like (Receiver BW UWB PRF) Pulse - like (Receiver BW UWB PRF) UWB Signal characteristics for Interference tests PRF (1/5/10 MHz) Modulation type PPM UWB Compatibility Study CEPT PT SE24 Victim Services Broadcast services (T-DAB / DVB-T) Radio Astronomy (Passive services) Earth Exploration Satellites (Active Passive) GPS UMTS Galileo PCN Aeronautical services COFDM ENG/OB SRDs 5GHz HIPERLAN Compatibility Study RA Contribution to CEPT To assess the UWB interference into (1) DVB-T (2) TDAB (MODE 1 2) (3) PCN (GSM) (4) Bluetooth (5) 5GHz RLAN Objectives (1) C/I Ratios (based on UWB power falling into victim receivers IF BW) (2) Minimum separation distances (3) Maximum permissible E.I.R.P. for UWB (4) Compare results with use of proposed CEPT and EMC/FCC limits. FCC UWB emissions limits for indoor communication and measurement systems. Units with center frequencies greater than 3.1 GHz FCC UWB emissions limits for outdoor communication and measurement handheld systems. Units with center frequencies greater than 3.1 GHz Proposed CEPT emissions limits for indoor and outdoor UWB communication and measurement systems. UWB Interference into DVB-T (1) Digital Terrestrial TV COFDM (multi carrier modulation) - 2k 8k FFT QPSK - 16QAM - 64QAM 2/3 FEC
