Re: [AFMUG] SpaceX Says Its 60 Starlink Satellites Are All Phoning Home (and Fading Out) | Space

[Mathew Howard]

Yeah, I know. And considering that it generally takes a pretty big storm to
take out a geostationary satellite signal, I imagine it won't be too big of
a problem... but I wouldn't be surprised if it did turn out to be a big
problem either.

Re: [AFMUG] SpaceX Says Its 60 Starlink Satellites Are All Phoning Home (and Fading Out) | Space

[Tim Withrow via AF]

What kind of bandwidth  capacity could each satellite have  at any given point? 
What is the usable bandwidth of their system?  Who makes a radio that big to 
carry/transmit such  capacity or is it an 
aggregate of small radio's?

Re: [AFMUG] SpaceX Says Its 60 Starlink Satellites Are All Phoning Home (and Fading Out) | Space

[Robert Andrews]

Consider, Starlink is going to be pretty busy for a good while replacing 
a lot of other legacy services, serving big customers like the US 
military, every mobile data service, and otherwise figuring out their 
business model for another 5 years.   I think we might have a great shot 
at using these for replacing our backhauls for another 5 years after 
that before they start looking at actual consumer sales.   Oh yeah and 
Tesla cars, gotta figure they are going to be including service through 
starlink with the antenna built in after a couple of year.  IF the 
performance is good and the reliability doesn't suck I imagine every 
vehicle would look at this as a great alternative to cell service.+


I cannot imagine they are going to be selling for less than $150/month 
for a good while...

I think one factor advocacy groups and govt critters need to keep in mind is 
that instead of robust competition, what could occur is “disruptive” pricing, 
having the effect of discouraging or bankrupting the competition.  And now some 
new entrant is the only game in town.  And if it turns out to be unreliable, or 
not to  have enough capacity,  or their speeds are actually best effort, or 
their satellites start dropping out of the sky, or whatever, people can’t 
switch back to their old provider.  Like being dissatisfied with online stores 
and assuming you can always switch back to the old brick and mortar store, from 
Uber and Lyft back to taxis and limos.  Sorry, they don’t exist anymore.

 

This is unlikely to happen in big cities, I doubt Comcast will go bankrupt 
because of Starlink.  But to just assume there will be lots of choices out in
