Appendix D Channels, Power Levels, and Antenna Gains

Maximum Power Levels and Antenna Gains

IEEE 802.11g

An improper combination of power level and antenna gain can result in equivalent isotropic radiated power (EIRP) above the amount allowed per regulatory domain. Table D-5indicates the maximum EIRP allowed for each data rate in the IEEE 802.11g regulatory domains.
