Appendix A Channels, Power Levels, and Antenna Gains
Maximum Power Levels and Antenna Gains
IEEE 802.11b
An improper combination of power level and antenna gain can result in EIRP above the amount allowed
per regulatory domain. Table A-4 indicates the maximum power levels and antenna gains allowed for
each IEEE 802.11b regulatory domain.
