Abel repeated throughout the presentation that the end-to-end architecture has been validated, which I believe means everything works as planned including uplink and downlink w/ mobile device.

If there were issues, they'd fix them and retest to a point where everything outside of the mobile device itself is working. Everything from doppler and delay compensation, enodeb backend integration, beamforming, etc all works as expected.

AST probably started off testing by using a modified mobile device so that it could first establish that the end-to-end architecture actually works and is validated.

Qualcomm/Iridium demo using a heavily modified phone

Qualcomm and Iridium did this in their first "demonstration" with reporters, as you can see from this picture of a modified android phone encapsulated in a brick to provide a bigger antenna and more power:.You would do this to ensure that you start with the least amount of variables that can go wrong so that you can test the entire end-to-end system to make sure it works. In order to conduct proper testing, you start with the absolute best case conditions which means you start with a modified mobile device that has a high power and a large antenna. First, AST has likely established 4G/5G Downlink and Uplink speeds.

This is our speculation and could be totally off, however it fits quite well with what AST has shared and what we've observed thus far. CatSE and I have chatted at length about potential testing steps AST has undertaken and how they relate to the latest quarterly update.
