Hi all,

Just installed GOS yesterday and working through settings, learning, and such. I'm loving it so far. I know that Airplane mode will turn off all radios. Anyway, I have some concerns about the 5G radio emissions so I'm wondering about ways to enable and disable it, therefore I have the following questions:

  1. "LTE Only" setting - does this actually disable the 5G radio/frequency emissions? i.e. so that emissions will only be that of my older 4G phone.
  2. "LTE" - I understand this is semantically that I prefer LTE but it can switch to others, including 5G. Correct?
    2.1 - If #2 is correct, are the 5G radio portion emissions always on, just not being used until there is no LTE? Or does the 5G stay turned off unless no LTE is available?

Any clarification on the above appreciated.

Regards

Hello, as I understand it:

  • "LTE Only" only allows to be on "4G" network, it does not switch to 2G, 3G or 5G.
  • "LTE" gives preference to the 4G network, but switches to 2G or 3G if the coverage of the former is bad.

In neither of the 2 options is 5G enabled.

Thank you both for the responses. I've read the docs but am still unclear if the settings affect 5G radio band emissions. As a contrived example for a wifi scenario, turning off wifi could just restrict software from connecting while leaving the radio and scanning underneath still going, or turning off wifi could also turn off the radio.

I'm attempting to learn the affect of the aforementioned settings on the actual 5G band emissions. I do not know if disabling the legacy code actually deactivates that part of the radio system as well.

Hopefully this clarifies what I'm asking. Again thanks for the responses.

    GOSExplorer I think a definitive answer would need to come from somebody who:

    1. Has access to the modem firmware source code or has access to RF test equipment, and
    2. Who re-checks evey time new modem firmware is released.

    Empirically it does not appear that such a person is reading this thread.

    Something that might work is going to a nearby university and asking to speak with a professor who is an expert on wireless modem design or RF propagation.
