Maximum allowed transmission power in the ETSI domain

In most Wi-Fi related documents, especially in study books, you read about the regulatory maximum allowed transmission power (EIRP)  for access points.

The values described are usually based on the standards as defined by the United States Federal Communications Commission (FCC).

As a Dutch based Wi-Fi consultant these are not the values I can use as a standard for my configurations. In Europe the standard is defined by the European Telecommunications Standards Institute (ETSI).

In the following tables give an overview of the different values used in the ETSI domain.

2.4 GHz - DSSS / CCK modulation

Channel	Center frequency	Maximum EIRP
1	2412 MHz	18 dBm (63 mW)

3	2422 MHz	18 dBm (63 mW)
4	2427 MHz	18 dBm (63 mW)
