>Testing has met or exceeded expectations:
>• Device Connection: Testing has not been limited to a single device, model, or operating
>system. Instead, SpaceX has successfully attached several unmodified models of Samsung
>Galaxy, Apple iPhone, and Google Pixel smartphones to the eNodeB on the SpaceX
>satellites. These devices have properly communicated for the duration of the satellite pass
>and did not experience harmful interference from adjacent-band devices.
>• Link Budget: SpaceX conducted tests up to its maximum authorized PFD of -80
>dBW/m 2 /MHz. Measured downlink and uplink link budgets fell within 1-2 dB of SpaceX’s
>modeled link budget, including realistic path losses, polarization losses, atmospheric
>losses, foliage losses, and human factors losses. This has enabled devices to communicate
>with the satellites through tree cover and indoors (although the direct-to-cell service is
>designed for outdoor use), and down to an elevation angle of 25 degrees. During the tests,
>SpaceX was able to demonstrate a peak download speed of over 17 Mbps.

They even report indoors cellphone to satellite connections. Though they don't mention what the typical speed is in various scenarios. Also I've not seen /s/ used before.
