No reason given, as of now.

Interestingly, the Internet of Things (IoT) will have a need for satellites, even though other connectivity methods will be the primary means. However, the expectation is that the IoT will include things in remote areas, not easily accessed by normal connectivity methods.

“From Mallart’s perspective, there is need for satellite in making the Internet reach everything it can, but satellite won’t be the primary connectivity most of the time.”

“The idea is that IoT is a global market and a lot of use cases require connectivity from very remote areas. It doesn’t make business sense to put Sigfox antennas in every single place in every country because it becomes too expensive, and there are some areas where there are very few objects to connect. … And of course there is an economic equation to solve between how many satellites you need to launch, what is the cost of the satellite, and how many base stations on the ground. This is a complex situation and working with the satellite companies can help solve these equations.”

“The Internet of Things is mostly about connecting sensors to the internet so we are able to sense activities on the ground, whether it is sensing soil moisture, or heat or chemicals in the ground. In logistics you are sensing the position of the vans.”

Satellites are not the primary source of connectivity: “Satellite is often looked at as a last resort for connectivity.”

Since there is so much interest in satellites for connectivity, it seems that the demand for connectivity is greater than the supply will be, on the ground, for some time to come.

Tom Billings has it nailed when he points out that these are not the regular, huge, expensive, massive, 15-year, geostationary satellites that we normally think of but are smaller, cheaper, faster, lower-orbit, and may be cubesats. The business model need to only last as long as it takes for alternate means of connectivity are available worldwide, although satellites may be the means of choice for oceangoing ships for quite some time.

“SkyNet (it isn’t officially called that, is it, for some reason?) “…

It’s called StarLink.

“…doesn’t send data directly to the phone in the user’s hand, I doubt that it’s worthwhile to launch hundreds of satellites.”

Actually, it will send data directly to a tablet in a user’s hand. It will use handheld phased array antenna technology to do so. You’re right, it won’t use hundreds of satellites. It will use 4,425 at first, and later 11,000.

“Because certainly soon a competitor will provide that capability.”

That’s fine. The satellites are designed to deorbit themselves after 5 years anyway, to make room for newer StarLink satellites with newer and more capable tech. Doing this with FH and BFR makes launching cheap enough to profit from such rapid technology turnover.

Still chance for good pre-dawn views for early risers on west coast.
