being able to operate a 1.2 to 1.8m size small VSAT in Xinjiang province
Right; I think people are visualising this like a sort of Thuraya iPhone, which it very much will not be, because physics.
I mean Thuraya is amazing if you in the middle of the ocean, but no one under 40 has ever used a modem at that speed before...
- walrus01 8y agoIf they are successful with some sort of most-flat-panel phased array that can talk to two or three satellites simultaneously, I don't think it will be quite as obvious on a roof as a 1.2m cheap small VSAT... But it will still need to be big enough to have sufficient gain for a real link budget, and CNR ratios for complex modulations. And its EIRP to Tx to a satellite >300km away at bitrates of 0.5 Mbps or better will be easy to find with portable spectrum analyzers hooked up to directional horn antennas.
