A GUI in modem firmware? There is room?

Have you seen this?
There is enough room in the modem firmware for a GUI to control the modem?
I don't understand...

I don't know if the following is what the YouTube video above is about?

What do you not understand about this? The modem itself is fundamentally a separate computer, with SoC and memory. The firmware resides with the GUI resides in that storage.

Regardless, why are you posting it here? Whether GUI or not, it's not applicable to OpenWrt. Unless you want to flash the modem's firmware with OpenWrt?

There is a lot of memory and processing power in a 4G/5G modem. Typically they are built with a smartphone ARM SoC and run a closed variant of the Android OS. The web server is no problem.

Thanks for the replies, I did not know that you could do this.
I always thought the modem had to be interfaced to separate router/computer, etc. for control.
Never knew there was "ample" memory for a firmware control GUI in the modem itself.

Yes, I am am a newbie, this is a side I have never used, but wish to learn, know, and use.

Is this possible for a Quectel 5G RM521F-GL ?

Not at all. AFAIK, there's only a single nascent effort to put an open source firmware for a modem: a Quectel model which is in the PinePhone. I've no idea how basic/barebones that firmware is or how big of a storage the modem has for OpenWrt even be flashed, but I think it's extremely unlikely. You need to go look up the derails of that project yourself.

Take a look at UF896 - Qualcomm MSM8916 LTE router ~384MiB RAM/2.4GiB flash, Android: OpenWrt?

This is unlikely with any other modem. Technically possible, but very difficult to do with the help you can expect from Qualcomm.
