What To Do When Broadband is Not An Option?
professorguy writes "I've been on the internet since 1984 (back before email addresses had @'s). But it looks like we're coming to the end of an era. From my home, I have 26.4 kbps dial-up access to the internet (you read that right). Since I am a hospital network administrator, it would be nice to do some stuff remotely when I am on 24/7 call. However, no cable or DSL comes anywhere near my house and because of the particular topography of my property (I'm on a heavily-forested, north-facing hillside), satellite is also not available. Heck, cell phones didn't even work here until January. So far, the technical people I've asked all have the same advice for reasonable connectivity: move. Move out of the house my wife and I built and lived in for 20 years. Has it really come to this? Am I doomed to be an internet refugee? Is this really my only option? Do you have an alternative solution for me?"
If you now have a cell tower within range, wouldn't cell phone based broadband be a possibility? Not the fastest, but much better than an analog modem.

If the problem is simply getting around a hill, maybe you can set up some kind of fixed-position high speed wireless that will relay a satellite link from somewhere with a clear vantage. It doesn't sound easy to set up, but if it's a choice between that and moving...

Strange, I just posted this earlier today! : http://slashdot.org/comments.pl?sid=305523&cid=20712265 As an Oklahoma resident, feel lucky if you even get DSL. Until Real Competition occurs, there will be no decent high-speed Internet in most areas outside medium cities. If a small town/rural Oklahoma region has even slow DSL, it is probably because the Law States they must have it order to be the telco monopoly in that area, etc... Though the phone company may claim service is available in my RURAL area, bridge-taps galore and 1970's equipment/wiring make this a non-reality. So.... I got a HAM Radio license, Bought 2 towers and 2 TR-6000 radios (http://www.tranzeo.com/products/radios/TR-6000-Series) with 2 high-gain directional dish antennas and 2 bi-directional amplifiers. Thanks to a strategically purchased rental property IN TOWN ON A HILL, I bridge the connection from its DSL to my home. Normally, the Amps are extreme overkill, but I live in the middle of the Greenbelt of Oklahoma (think dense 30-40ft. Oak Trees) and the Fresnel Zones (http://en.wikipedia.org/wiki/Fresnel_zone) are a real bitch with tree leaves. Works like a champ. Why not Satellite, AWFUL Latency and VERY HIGH Prices!
If you have line of sight to someone with broadband (even if it's from your roof or high in a tree) you can get a good WiFi signal with a 24 dB dish (~$60) - I've used them to easily get SSIDs on consumer-grade routers in stranger's houses two miles away (I assume there were a few walls in the way). One assumes the connection could be made much better if both sides of it uses these dishes. These dishes will even work through a little foliage if it's not too thick. You just need to get to know any line-of-sight neighbors so a connection with their network can be on the up and up. You can even agree to install broadband at a suitable site in exchange for access.

wow that was fast o_O Google's spider must get the rss feed or something.
The same thought popped into my head -- at least I *think* it's the same thought, I don't know the terminology.
Back in college in the mid 1980s I shared an off-campus apartment with a bunch of other geeks like me, and we looked into getting a connection to the school's computer system (which they were surprisingly friendly about). I won't say it was "the Internet" since it was in a lot of pieces back then (and the school seemed to be on everything *except* the ARPAnet until very late -- even Mailnet, which was barely even anything).
Anyway the local telephone company (NYtel) said they could give us a 2-wire leased line to the school for about $36/mo, or a 4-wire one for $72/mo. The catches were: (1) about $600 for installation, (2) it's not one run of copper all the way there so we couldn't just run 20mA current loop or something, we'd need real leased line modems (I eventually picked up a pair of Gandalf 9600 BPS line driver/receivers cheap but I don't even know if that was the right thing, and that was about when dialups started getting that fast so it was pointless), and (3) the school wasn't an ISP, so it wasn't at all clear what would go at the other end (in those days, translating between SLIP and Ethernet didn't just mean stuffing Linux into some old clunker PC). So we never bit, but I regret it, it sure would have been educational.
Anyway those are 1980s upstate NY prices. I'm sure it's more now (and, we weren't talking about a very long distance) but I'll bet you earn more than you did in the 1980s too. And presumably the data rates are way higher now, and most ISPs would know what to do with their end. OK so it wouldn't be as cheap as DSL but how important is the Internet to you?
Also it might be worth looking into RF modems. Before cable broadband came to my neighborhood and made it all easy, I had the local mom + pop ISP (the best kind!) mostly talked into letting me mount a doodad in their attic (since they were only a block away -- if they'd been on the same block I would have just begged neighbors to let me string wires through the trees), and I was just hemming and hawing over which pair of doodads to buy. The data rates aren't fantastic but you can sure beat 26kbps. Anyway even if you don't sell the ISP themselves on the idea, maybe you could at least get their permission to buy space on someone's connection who's closer to you, and talk *them* into sticking a horn antenna on their porch railing or whatever. Privacy is out the window of course so that would have to be OK with you.
Just for reference, the reason it was designed that way is because in the beginning of telecommunication, the exchange station would just feed 48 V into a line on which the microphones and speakers of both participating telephones were simply connected in series. It's obviously an extremely simple design; befitting the era, I guess. I don't know how it is done these days, but in the days of old, capacitors and resistors weren't used to cancel out feedback, but rather a very special transformer circuit called a duplex coil. Nowadays, it seems to be hard even to find information on how it was constructed.
You might wonder why I know these things; it is simply because I've been trying to design a "telephone soundcard" (like a modem, but without the modulation/demodulation part). It turns out that it is rather easy to construct a converter from a two-wire circuit to a four-wire circuit using two opamps and five resistors. Of course, that won't make the line unloaded.
Back in the AT&T days (pre 1982) when all phone outlets were 4 conductor and pulse was the norm, all 4 wires were used.
I had a phone outlet in my room but but no phone and I used to listen to my sister's telephone conversations (like a little brother would do) by hooking up a speaker to the bottom 2 terminals.
I figured out that I could pulse dial my friends by tapping on the terminals and use another speaker for a microphone.
Back then, you just couldn't get another phone without parental approval because phones were leased and no one had a phone sitting around so I used old tape recorder parts.
