News, No. 52, according to the Ministry of Information Industry and the 2019 announcement:
5.8GHz wireless LAN, and spreading the current transmit power less than or equal 25mW (14dBm) is, 2.4GHz wireless LAN and transmit power less than or equal spreading 10mW (10dBm) belong micropower short range radio transmission equipment without making Type Approval ,
Carefully check the device information when applying for approval of your business, and communication device transmit power and laboratories.
appendix:
dBm is a characterization of the absolute value of the amount of power, is calculated as: 10 lgP (power value / 1mW)
[Example 1] If the power P is 1mW, it is converted in dBm after 0dBm.
[Example 2] For the 40W power, were converted value in dBm should by:
10 lg (40W/1mW)=10 lg (40000) =10 Ig4+10 Ig10+10 Ig1000=46dBm。
