> Unlike traditional parabolic dish antennas, our phased array antenna can connect with multiple satellites simultaneously.

if that's how they plan to reach more than 1Gbps, then that's not 100Gbps per satellite, that's 100 for a collection of satellites.

Starlink is about 100Mbps. That's 1000x times less than 100Gbps
