2.6Technical Information
The requirement for the following technical information of the EUT was tested in this report:
Frequency Range
802.11b/g/n(20 MHz): 2.412 GHz - 2.462 GHz
fc = 2412 MHz + (N-1)*5 MHz, where
- fc = “Operating Frequency” in MHz,
- N = “Channel Number” with the range from 1 to 11.
802.11n(40 MHz): 2.422 GHz - 2.452 GHz
fc = 2412 MHz + (N-1)*5 MHz, where
- fc = “Operating Frequency” in MHz,
- N = “Channel Number” with the range from 3 to 9.

2.7Additional Instructions
EUT Software Settings:
Mode
Special software is used.
The software provided by client to enable the EUT under
transmission condition continuously at specific channel
frequencies individually.
During testing. Channel and Power Controlling Software provided by the customer was used to control the
operating channel as well as the output power level. The RF output power selection is for the setting of RF output
power expected by the customer and is going to be fixed on the firmware of the final end product.
