Good. I hope it works. Free Wi-Fi would be nice.
UNITED NATIONS TO DISCUSS ‘OUTERNET’ REGULATION, TAXATION
The existing WiFi frequencies go right through the atmosphere. How do I know? I have used them, as a ham radio operator, to communicate with satellites.
You don't know what you're talking about.
Doppler shift correction is in every smart phone, in the GPS. It's all software now.
It would be better to place the equipment in every commercial airliner.... they are up high and have great line-of-sight range.
All the ground-side devices need to transmit to the sat-side. This takes lots of power, especially if the ground antenna is not directed - an omni antenna. But, this could work when lithium ion batteries are replaced by fission or fusion batteries...
That is the exact direction things are going in, except rather than beaming towards cell towers, they transmit/receive to satellites, to get the bandwidth needed... and the connectivity over the oceans and sparse land without cell towers.
Yeah, I wonder that myself. It is doable in theory because at 2400 Mc, the signals are line of sight but will the average PC or phone have enough “oomph” to talk to satellites? Maybe.... I know amateur radio operators have been on own to use even the standard rubber ducky antenna to hit the OSCAR satellites and the ISS as well have have reliable comms. I could probably do it with my Baofeng handheld. I’ve talked to Canada on 1 watt on my HT on 2 meters (144-148 Mc) using my rubber duck antenna at the edge of Lake Erie, the signal went 50 miles across the water and 30 miles into Ontario. I’d like to know more about this although I’m dubious if the average laptop’s signal can make it into space but IIRC, the early OSCAR satellite the hams made in the 1960’s put out like 10 to 100 mW of people and they could heat them so I assume the reverse can be true.
I made that point too, at 2400 Mc, I think it is doable. Heck, we hams have a band next to it at around 2300 Mc and that is a sat band too.
Step 1 in the evil alien plot to enslave humanity.
Cybus, Arch Angel Netowrk, Daleks, take your pick...
It would not be too difficult to use quad copters to provide connectivity across very large areas.
You could tether the vehicles to a simple ground station using a length of small, strong, twisted pair wire.
If you send high voltage AC up the wire there will be minimal loss and you can convert to lower voltage DC to run the quad copter’s motors and electronics.
Data could be sent up/down the twisted pair wire as well.
A height of say 500 or 1000 feet and you would get really good coverage....and communications between vehicles at altitude would be very long-range.
Extreme weather might be a problem from time to time but it’s still an interesting idea.
So, what might be the range for that?
High altitude VOR ranges are, what, in the 200 mile range?
That leaves 2600 miles to cover away from land on a 3000 mile trans-atlantic crossing.
Compare to using satellites, always overhead, any weather.
Gives “distributed denial of service” a whole new meaning. Thanks Hojczyk.
Sats are, of course, much better. I was just considering what could be done on a small budget.
Ham operators are capable of creating the simple system I described.
Interesting. Linky?
They actually called to give me the offer
Thanks for the link. Here’s one that’s more current:

Would be interesting to know if there are taxpayer funds involved.
