MHz-POP makes the most sense in cell networks, where an operator (AT&T, T-Mobile,...) wants to acquire a spectrum license in a particular region of the country. Evaluating the MHz-…

A MHz-POP is just bandwidth times population covered by the Geographic Service Area (i.e., where the company is licensed to operate). For example, in the US, they would have 11.5 M…

This made it to the cover of Nature with a similar headline [0]. I guess that they are also "overhyping everything". [0] https://pbs.twimg.com/media/DsmahXYXoAAkaoI?format=jpg&name…

No, it will not be possible, no matter what Elon says. Starlink operates in portions of the Ku and Ka bands that are reserved for Earth-to-space comms, not for space-to-space comms…

There is plenty of bandwidth to achieve more than 1 Gbps of throughput from a 3-U cubesat (see Planet with their latest X-band comms-system [1], which results in more than 50 GB pe…

Well, look at Oneweb as an example. They have raised 3+ billions, still need more funding and their total system throughout is not that much larger than Viasat-3's,which has a cost…

Developing compatible systems would be very expensive. There are very few standards in Space Comms., specially for satellite-to-satellite Comms.

SpaceX satellites cannot handle 1 Tbps each, they can handle 23 Gbps each according to their FCC filling.

Specially now that the satellites have no crosslinks.

It's not true. LEO systems are far more CAPEX intensive than GEO, and neither Starlink, Oneweb, Telesat, or Kuiper will be cheaper than Viasat-3 and will not be able to compete in …
