7Transmit power / Power densityMax. -15 dBuA/m at 10mThe maximum field strength is specified in a bandwidth of 10 kHz.
The maximum allowed field strength is -5 dBuA/m at 10m for systems operating at bandwidths larger than 10 kHz whilst keeping the density limit of -15 dBuA/m at 10m in a bandwidth of 10 kHz.
In specific bands mentioned in other radio interface regulations, higher field strengths limits and additional usage restrictions apply.
