3 Terms, definitions and abbreviations
3.1 Terms and Definitions
3.1.1
equivalent isotropic radiated power
product of the power supplied to the antenna and the gain (absolute or omnidirectional) relative to the omnidirectional antenna in a specified direction
3.1.2
occupied bandwidth
occupied bandwidth means that the average power emitted below the lower frequency limit and above the upper frequency limit of the signal under test is equal to the specified percentage b/2 of the total average power of a given emission, respectively. Unless otherwise specified in the ITU-R Recommendations for certain appropriate launch classes, the b/2 value shall be 0.5%
3.1.3
spurious emission
spurious emission refers to the unwanted emission of the equipment in spurious domain
3.1.4
frequency tolerance
the maximum allowable deviation of the center frequency of the band occupied by the transmission from the assigned frequency (or the characteristic frequency of the transmission from the reference frequency)
3.1.5
antenna gain
under the condition of equal input power, the ratio of the power density of the signal generated by the actual antenna and the ideal radiation unit at the same point in space

4 Consistency Requirements for Band Configuration
4.1 Operating Frequency Range
The operating frequency range of public wireless LAN equipment in 2.4 GHz band is 2400 MHz - 2483.5 MHz.
The operating frequency range of public wireless LAN equipment in 5.1 GHz band is 5150 MHz - 5350 MHz.
The operating frequency range of public wireless LAN equipment in 5.8 GHz band is 5725 MHz - 5850 MHz.
4.2 Operating Channel
1) The public wireless LAN equipment working in the 2.4 GHz band has an available bandwidth of 65 MHz and is divided into 13 channels. The relationship between channel center frequency and channel number is shown in Equation (1).
Channel center frequency = 2412 + 5 × (N-1) (MHz) (1)
Where N = 1, 2, 3, …, 13.
See Tables 1 and 2 for the channel configuration scheme.
