2400-2483.5 MHz (4 W)
Operation of wireless network equipment on the Australian 2.4 GHz band is governed by Sections 55, 56, and 59 of the Radiocommunications (Low Interference Potential Devices) Class Licence 2015, which was last updated in June 2018.
LIPD Class 2000 legislation permits the operation of Frequency hopping, WiFi and RLAN transmitters between the range of 2400 to 2483.5 MHz, provided they operate under the conditions outlined below. The 83.5 MHz bandwidth allows most wireless radios to operate with channel sizes of 20, 40, or 80 MHz. Engineers often voluntarily coordinate WiFi networks to operate on three non-overlapping 20 MHz channels (channels 1, 6, and 11).
The transmitter must have a maximum EIRP of 4 Watt. The radiated peak power spectral density in any 3 kHz must not exceed 25 mW per 3 kHz. A minimum of 75 hopping frequencies must be used.
Equipment incapable of the above conditions must use a minimum of 15 hopping frequencies and limit power output to 500 mW.
