Understanding Radio Transmit Power

Radio cell size is controlled by the transmitted power level of the wireless device and controls
interference between cells. The maximum transmit power is limited according to regulatory region.
An improper combination of transmit power level and antenna gain can result in equivalent isotropic
radiated power (EIRP) that exceeds the amount allowed per regulatory domain.
In some situations, the channel selection or country code affects the transmit power level. See the
Channel Frequencies"
