Limiting the Output Power

Please note that the power limits documented in this chapter must not be

exceeded in the end product to keep the modular approval valid. Examples

that fulfill this requirement are documented in the following sections.

Please note that it is not recommended to use functions like

esp_wifi_set_max_tx_power, because the device could transmit with

restricted output power settings before the function is called.

For a valid modular approval, the radiated power must not exceed certain limits. These are

summarized as follows:
