Which may indicate with a high gain antenna, up to 4 watts is permitted.

(1) For frequency hopping systems in the 2400-2483.5 MHz bandĮmploying at least 75 hopping channels, and all frequency hopping (b) The maximum peak output power of the intentional radiator You cannot get a more powerful wireless device without an FCC license than 1 watt for 802.11x protocols. One Watt (1000mw) is the FCC limit on WiFi devices.When using an omnidirectional antenna (see "Different Kinds of Antennas" earlier in this chapter for more information about types of antennas) with fewer than 6 decibels (dB) gain, the FCC requires EIRP to be under one watt. EIRP represents the total effective transmitting power of the radio in a Wi-Fi card or access point, including adding gains from an antenna and subtracting losses from an antenna cable. From the viewpoint of the FCC regulations, the power of a Wi-Fi broadcast is measured in units of equivalent isotropically radiated power (EIRP). The Federal Communications Commission (FCC) has which regulate power for Wi-Fi networks.
