Re: Elon Musk's Starlink satellites over Cambodia
The local CPP departments in villages and sangkats are actually pretty well organized / informed. If, but only if, the big boss makes this a priority thing, it will be very difficult to use starlink in Cambodia. Don't underestimate the CPP when it comes to keeping and maintaining control.Jerry Atrick wrote: ↑Wed Apr 14, 2021 4:10 pmlol, let them tryKammekor wrote: ↑Wed Apr 14, 2021 4:09 pmThey will probably follow the suggestions from their brother in arms, China, and ban it.Jerry Atrick wrote: ↑Wed Apr 14, 2021 4:06 pmAs if anybody in Cambodia gives a single, flying, fuck about what a dish or antennae is for.nerdlinger wrote: ↑Wed Apr 14, 2021 4:01 pm Apparently although the dish does look like a classic dish, the underlying tech is a phased antenna array, which theoretically means you could build one that looks nothing like a dish.

If it really came to that, you could house it in a box made of that tinted plastic roofing stuff so no-one could see it.Kammekor wrote: ↑Wed Apr 14, 2021 4:07 pmFor receiving the dish is still a requirement.

Re: Elon Musk's Starlink satellites over Cambodia
I don't know. The satellites orbit at an altitude of 340 km, so in the ideal case (which virtually never happens) the signal has to travel that distance from your antenna to the satellite and back. In reality the distance will be much longer because the satellite hardly ever is right above your head. Try Pythagoras law on that one and amaze yourself about the distance the signal has to cover in non optimal cases (99.9999%).timmydownawell wrote: ↑Wed Apr 14, 2021 4:17 pmIf it really came to that, you could house it in a box made of that tinted plastic roofing stuff so no-one could see it.Kammekor wrote: ↑Wed Apr 14, 2021 4:07 pmFor receiving the dish is still a requirement.

Any barrier between the antenna and the satellite will weaken the signal. Not sure if the reduction will be enough to make the system fail. In the beta phase with fewer satellites (thus longer distances) the system will be more frugal than with all stations in operation.

Re: Elon Musk's Starlink satellites over Cambodia
When I first visited Cambodia; the big man was threatening to cancel 3G because of the "risk to the social fabric of society".Kammekor wrote: ↑Wed Apr 14, 2021 4:16 pm

That didn't happen.
Every other year we have chicken lickens running around screeching about how our sim cards will cease working unless we register ID cards to them by x date.
That didn't happen.
I do not see how a starlink device could be tracked or monitored by local authorities; there won't be starlink country office; nothing will stop consumers worldwide buying these units and connecting or assembling their own and then connecting. Time will tell ofc.

Re: Elon Musk's Starlink satellites over Cambodia
I have two dishes under a plastic sheeting roof with steel trusses, and they pick up TV from satellites at 35,000km altitude, so I don't think it'll be an issue.Kammekor wrote: ↑Wed Apr 14, 2021 4:24 pmI don't know.

Re: Elon Musk's Starlink satellites over Cambodia
First of all they could simply intercept the boxes with antennas when imported. Second, a flashy white antenna (with Starlink log?) fully exposed to the sky at a certain angle with nearly a diameter of 1 meter will be pretty easy to spot. of course there will be the occasional house in the bush using one unnoticed, but I'm talking about serious adoption, let's say 10-100k users in Cambodia. I don't think they will allow because it will be a major hole in their safety net, at least in their world.Jerry Atrick wrote: ↑Wed Apr 14, 2021 4:25 pm I do not see how a starlink device could be tracked or monitored by local authorities; there won't be starlink country office; nothing will stop consumers worldwide buying these units and connecting or assembling their own and then connecting.

Again, it comes down to how eager they are. My guess is, they will be pretty eager. My guess is also Starlink won't be a success in China.

I'll report back on how it works in a year or so
Re: Elon Musk's Starlink satellites over Cambodia
You talk about receiving data. With Starlink you're looking at two way communication. Receive and send. Total different playing field, hence the extremely low orbit compared to 'old style' communication satellites.timmydownawell wrote: ↑Wed Apr 14, 2021 4:31 pm I have two dishes under a plastic sheeting roof with steel trusses, and they pick up TV from satellites at 35,000km altitude, so I don't think it'll be an issue.
The Starlink antenna will have maybe 1% of the sending power of the satellite, probably even less. That's where the problems might occur.
