LTE Carrier Aggregation

Post by SoNic67 » Sat Nov 16, 2019 6:30 am

I saw on some of your other boards that an LTE modem can be "forced" to work in CA mode with AT commands sent to it. But on the normal hones, that function is provisioned by the carrier.
My question is: Isn't the carrier enforce/verifies that CA compliance later?

For example, I have read that on a certain MVNO (Tello), the Samsung Galaxy 8, 9 don't get CA, but a Pixel 3 gets CA.
Is that because the Pixel ignores the provisioning by MVNO? Or is some other deal going on at the higher level (main carrier network)?

CA is entirely controlled by the carrier, but you can limit your modem to only certain bands, but if they aren't available on the tower side theres nothing you can do about that.

That's what I thought. So then, Verizon allows Pixel devices to have CA even when they are on a MVNO, but not other devices?

I don't know the exact situation here, but I have a Verizon Samsung S8 and I get 3xCA no problem.

No idea, I would guess they get less wireless resources since they share the infrastructure from another carrier.
