I have found different documents specifying the maximum permitted radiated power in the 868 MHz region. However, the maximum permitted radiated power depends on the spectral characteristics of the signal (modulation format, bandwidth etc) as well as the characteristics of the antenna used.
My question is: what is the maximum permissible radiated power for the XBee PRO 868 MHz assuming a monopole antenna. Can I use the maximum (300 mW) power that the device can transmit ?
