# Commission Implementing Decision (EU) 2019/785 of 14 May 2019 on the harmonisation of radio spectrum for equipment using ultra-wideband technology in the Union and repealing Decision 2007/131/EC (notified under document C(2019) 3461) (Text with EEA relevance), Division 4: UWB ONBOARD AIRCRAFT

Extent: E+W+S+N.I.

The values for maximum mean power spectral density (e.i.r.p.) and maximum peak power (e.i.r.p.) for short-range devices using UWB technology, with or without use of mitigation techniques are listed in the table below.
Alternative mitigation techniques, such as the use of shielded portholes, may be used if they ensure at least an equivalent performance.
7,25 to 7,75 GHz (Fixed Satellite Service) and 7,45 to 7,55 GHz (Meteorological Satellite) protection: – 51,3 – 20 × log10(10[km]/x[km])(dBm/MHz) for heights above ground of over 1 000 m, where x is the aircraft height above ground in kilometres, – 71,3 dBm/MHz for heights above ground of 1 000 m and below.
7,75 to 7,9 GHz (Meteorological Satellite) protection:
– 44,3 – 20 × log10(10 [km]/x[km]) (dBm/MHz) for heights above ground of over 1 000 m, where x is the aircraft height above ground in kilometres, and – 64,3 dBm/MHz for heights above ground of 1 000 m and below.
