MAX TX POWER Health Risk? Interference?

The DW1000 IC has a maximum Tx Power Output of 33.5 db (-35db/MHz) (2.2387 Watt)

-if the power of the DW1000 is set at maximum, can Hurt Humans due to RF Expose?

-if the power of the DW1000 is set at maximum, can Interfere with devices that work in the same frequency bands?

Hi DonQuijote,

If you are using DW1000 at maximum TX power(-33.5dBm/MHz= 0.446mW/MHz) can not hurt humans but, there is a regulatory limit which is -41.3dBm/MHz. Thus, you need to calibrate the TX output power with your device not to exceed the regulatory limit.

I would like to know the power spectral density (PSD) of dw1000 at a frequency of -41.3 dBm/MHz, and the transmit power under the condition of bandwidth of 500 MHz and central frequency of 4 GHz. Additionally, please provide the calculation formula.
