You'd need too much power.

If you go outside of the legal frequency bands or power levels the FCC WILL find you and shut you down, and i think it's a felony law because it's federal air space.

Bandwidth would probably be awful at those frequencies

I suggest getting a smartphone with a data plan and tethering (after you root it)

Internets aren't a one way street like a radio or TV broadcast. You would need a big transmitter at either end.

Ground radio

its completely possible, but it wouldn't be all that fast. Do you have an amateur license?

>>253536
no, but I would try to get one
just seeing what options there are for living off the grid.

I had that exact same idea after researching Tesla.

I can tell you that satellite and cell phone internet sucks big hairy balls. A land line connection for internet is the best option. Obviously, this depends on your specific needs.

Second best is WLAN. Look into making wokfi/parabolic dishes for line-of-site transmission. They can go a long long ways and if you use repeaters you can go forever.

I am confused on tesla radio
summary?

>>253579
You use the soil, the Earth itself to transmit signals into and receive signals from. You want radio? You pound a rod into the ground outside. You want internet? Pound a rod into the ground outside.

No more wires, no more connection problems from satellites, it is one of those dream technologies that no one gives any credit. Yet, we've had the technology to do it for decades.

>>253585
Also, "you want electricity? Pound a rod into the ground outside" and get the power right from the ground.

To do this, everyone will need to stop making grounds in their electronics like we have today, otherwise all of that crap gets fried. lol

Technically possible, but I think the datarate would be rather low, you'd need two distinct channels for full-duplex operation, and (don't quote me on this) I don't think FCC rules regarding use of the amateur radio bands would allow this, or at least you'd be limited to certain bands. Check with them on that, my information is way out of date but I do believe they still get rather pissy over misuse of the airwaves

If the goal is to have internet access in the middle of nowhere wirelessly, might I suggest radio modems? I can't remember who made them, but at one job I had we worked with some dataradios that had ethernet connections to them, and operated as a transparent wireless bridge, which means once you had a pair of them set up, all you had to do is plug into them and you're good to go. I think the range was something on the order of 20-25 miles with decent gain antennas, better if you know where you're going and can set up and use directional antennas for higher gain. There's also cellular modems using a wireless provider's network, but you'd have to pay for the service, there's satellite internet service (not cheap, and while the speed might be good in the right circumstances, the latency is very high), and if it's only a couple miles you need to go with it, you can get amplfiers for WiFi to feed into high-gain outdoor antennas.

I don't think it's a felony, but I think they would confiscate equipment and/or make you pay a fine for every day you were in violation of FCC rules.

>>253536
You wouldn't really be "living off the grid" this way, you'd have to have a generator or a pretty big solar array with a bank of storage batteries to keep your transceiver setup working.

How close is you nearest source of normal internet OP?

>>253593
data is allowed on most of the amateur bands.

the problem with this thread is we have no info at all.

>>253601
*nodding*

I think if anything a radio modem setup would be the most practical solution. They don't require any sort of licensing, and with a good antenna setup you can get some decent distance out of them, and the datarate on some of them isn't totally unreasonably low. You wouldn't want to play a first-person shooter over them, but for normal internet browsing and email it would work fine.

this is just speculation at his point, no detail sorry :(
I know there are too many dreamer threads on this board, but alas this is probably one of them

>>253585
wouldnt that just have way too much resistance?

>>253593
awesome, will look into this

>>253595
i know it's a felony to broadcast on a used/dedicated frequency like 900Mhz/1900 MHz (cell phone jammers) that carries a 10 year sentence if they want to prosecute.

but maybe if it's a mostly unused band they won't be as harsh.

you couldn't transmit on the regular shortwave/amateur radio bands though, since you'd be blocking out everyone else trying to use it and they would probably triangulate/locate you within 30 minutes and call the cops on you,

>>253614
I take that back, maybe you could keep the power levels within what you're legally allowed to broadcast.

Amateur radio is going to suck for legality reasons. Commercial radio equipment meant specifically for networking is the way to do it for speeds up to a few hundred mbit/s, but you have to ask you can't afford it :( You can probably work with a dish-to-dish network with consumer wifi routers if you're dedicated and this is certainly more affordable.

This gets more difficult if you have to go multiple hops, but I know people who do it with commercial stuff, total distance maybe 60-80km.

http://www.irlp.net/ this stuff? That doesn't sound like what you need though.

If you only want to do point to point between two locations, setup two consumer wi-fi devices (higher power is better but in consumer range you probably don't have a choice) pointed at each other using recycled dish /directv antennas, depending on range, but that should be pretty reasonable, like 2 miles, maybe 4 if both have satellite dishes.

These guys seem pretty legit, just skimmed them though, google yourself

Do we have DIY 2.4ghz amplifiers?

>>253459 Fellas at the Freakin FCC!

There are many ways to do this legally. And, you can get whatever performance you want depending on your budget.

Consider this: http://www.ceragon.com/product.asp?ID=7

Turn-key point to point ethernet over 2.4GHz/6GHz (unlicenced), 48MBps at a distance of 80kms. These types of devices are used between point-to-point LANs in cities all the time. It's cheaper than running fibre.
