Do you happen to know when Apple will be able to put a modem into a MacBook Pro?

> LTE Band 53 is a part of the TDD (Time Division Duplex) LTE spectrum that requires only a single frequency band for both the uplink and downlink. LTE Band 53 has a frequency range from 2483.5 - 2495 MHz with a bandwidth of 11.5 MHz.

Quite impressive they can receive that on the satellite with 1W (guess) of power and a not very directional antenna in the iPhone.

In the earlier videos on it they showed that the phone has to be pointed a certain way (which makes sense given the power constraints), but you are guided through the process.

So Back to qualcomm aye? The ghost that can never be killed.

Strictly speaking, if that were the case then the iPhone 13 would have been able to do it. [0]

The technology (Band 53/n53) and the timeline (end of 2022) are mentioned in the Sep 2022 SEC filing of the agreement between Globalsat and Apple. [1]
