The FCC ID web site lists the power output of devices it has checked their supported frequency ranges
For the Eufy product range ((FCC ID 2AOKB-T8 [results]), the home base’s list the 2.412-2.462 GHz WiFi range (which is used to connected to the Eufy devices i.e. camera’s, etc) and their Power Output in mW
However, it also lists 902-928 MHz, 915-928 MHz and 920-920.8 MHz frequency ranges but these do not have and Power Output values apart from the T8001 and T8001CL home bases
The only Eufy devices that have those frequency ranges listed is eufyCam (T8111), eufyCam (T8111CL), eufyCamE (T8112).
Were those 902-928 MHz, 915-928 MHz and 920-920.8 MHz frequency ranges used for communication between the home bases and the those cameras before moving to the 2.412-2.462 GHz frequency range?
