Re: connecting to the sky

They started testing with a WiFi-like system. Now they seem to be testing with a 70-80GHz connection that bounces off a basestation on the ground that sends signals up to populate among the balloon network. They haven't exactly been effusive with technical details, unsurprisingly.

And a James Bond supervillain, who is gushing cash at a quite rapid rate :)

Except that SpaceX is led by a potential James Bond supervillain.

Re: connecting to the sky
So, they are going to make WiFi work at 15 Miles (75,000 ft)?  Or are they going to use it to power something on the ground...which you can do with any connection.  Not sure I want a transmitter that can send back to the balloon next to my head.

There are other actors as well like I said, I didn't research it more than 5 minutes and found we have coverage.  Just saying.

Re: connecting to the sky
Not sure that's any more or less of a moonshot than Project Loon at this point though...

Re: connecting to the sky
Coupla points:

 

Google is trying to make this work with LTE and WiFi, so that a broadband service is easily accessible to users. Immarsat's BGAN tops out around 400-kbit/s could be interesting for IoT but not for broadband.

Google is doing this to eventually boost their revenue, hence they need a relatively fast data connection. If they can get cheap wireless broadband going, they get more served mobile ad revenue. They might couch it as altruistic, but opening up broadband access benefits them in the end.

Re: connecting to the sky
So, I did a Google Search...

Here is the coverage map of the very first company that I clicked on:

http://www.groundcontrol.com/bgan/BGAN_Global_Coverage_Map.pdf

As I said, I think we have essentially 100% Internet coverage today.  It may be too costly.  But I don't think "bringing Internet where there is none" seems like a likely explanation for Project Loon.  Reducing the cost of rural Broadband maybe?

Re: connecting to the sky
SpaceX has said it's looking into launching a "constellation" of thousands of LEO satellites. Kind of like an Iridium 2.0.

Re: connecting to the sky
I am talking about the existing satellites.  Oil and Gas companies use sat comms globallly...so it has to be like everywhere today.  I mean right now this second.  It may be too expensive...but I think 100% global coverage is close if not actual as we speak.  That is what I am asking.

Re: connecting to the sky
Who's gonna pay to put up satellites with the latest tech on board though? Google is clearly looking for a cheaper way to get a baseline of connectivity to people. Will it work? Well there's the rub, right?
