Technical requirements for devices using UWB technology in bands below 10.6 GHz
Maximum e.i.r.p. limits
| Frequency range | Maximum mean e.i.r.p. spectral density (dBm/MHz) | Maximum peak e.i.r.p. (measured in 50 MHz) |
| Below 1.6 GHz | -90 dBm/MHz | -50 dBm |
| 1.6 to 2.7 Ghz | -85 dBm/MHz | -45 dBm |
| 2.7 to 3.4 Ghz | -70 dBm/MHz | -36 dBm |
| 3.4 to 3.8 Ghz | -80 dBm/MHz | -40 dBm |
| 3.8 to 4.2 GHz | -70 dBm/MHz | -30 dBm |
| 4.2 to 4.8 GHz (Notes 1 and 2) | -70 dBm/MHz | -30 dBm |
| 4.8 to 6 GHz | -70 dBm/MHz | -30 dBm |
| 6 to 8.5 GHz (Note 2) | -41.3 dBm/MHz | 0 dBm |
| 8.5 to 10.6 GHz | -65 dBm/MHz | -25 dBm |
| Above 10.6 GHz | -85 dBm/MHz | -45 dBm |
Note 1: UWB devices placed on the market before 31st December 2010 are permitted to operate in the frequency band 4.2 - 4.8 GHz with a maximum mean e.i.r.p. spectral density of -41.3 dBm/MHz and a maximum peak of 0dBm measured in 50 MHz.
Note 2: In case of devices installed in road and rail vehicles, operation is subject to the implementation of Transmit Power control (TPC) with a range of 12 dB with respect to the maximum permitted radiated power. If no TPC is implemented, the maximum mean e.i.r.p. spectral density is -53.3 dBm/MHz.
