C2 Jolla Community Phone - 4G LTE bands/channels/frequencies

[attah]

@teleshoes

there aren’t that many modems to choose from,

This is true; but we are fairly sure these are different.

@teleshoes

they were both pre-existing devices selected by the same company targeting the same markets.

I don’t think the selection goes much beyond “will work fine” - as if there were many options.

@teleshoes

except of course it does?

No. I work with this.

@teleshoes

the same component, the modem-rf module, controls both nr and lte

…and a key functionality is to be able to listen to both at the same time.
For 5G it is even to be able to use them at the same time (even before considering things like dual-sim).
They may or may not be in the same IC, but different set of gates.

While some 5g is deployed at nor near classic 4G frequencies - a big thing is also enabling frequencies that will never see 4G.

@teleshoes

this suggests that they dont give a fig for only supporting phones that support a superset of the current RF.

Parse error.
