Re: [M100] Xbee and m100
Yup, and they mean that. There are higher gain antennas, but you can get in big trouble for using them without a permit, or for running the full power into the 15db gain antenna. If they FCC imposes fines, they are generally very high.

There are restrictions on what you can do with those type accepted routers and switches, and what kind of antennas you can use without special permits or licensing.

Re: [M100] Xbee and m100
Wait til you read about bouncing signals off of derelict satellites... ;) I read about the wifi when you mentioned it originally, but I'm trying to avoid relying on a traditional internet connection. I guess long range wifi is a thing, though. I'll be reading about QRSS. I've seen it mentioned in my brief research on this topic, but I'm unfamiliar with it beyond that.

OK, to clear up a couple of things here. QRSS is ultra slow morse code. Not at all what you're looking for I think. Yes, it can travel really long distances on low power, but you aren't going to download Netflix videos with it unless you have amazing patience and a 10 thousand year lifespan. :D QRP and QRPP are low power signaling in the ham radio service, and can incorporate many modes and speeds. Looking at QRP information will give you a feeling for how much you can do with very little power, but long distance communication on milliwatts normally takes place in the HF range, not microwaves where broadband networking operates. Yes, you can go a long distance with just line of sight as long as conditions are good at 900MHz. However, beware of the FCC regulations. There are restrictions on what you can do with those type accepted routers and switches, and what kind of antennas you can use without special permits or licensing. I don't know all the ins and outs, but the hams using broadband Mesh networking get away with some tricks because they are in a shared ham band and have licenses. Be aware too that setting up high gain directional point to point antennas requires a lot of patience to get them aimed right and some skill at installing them so the wind won't change the aim on you. Good luck, and let us know how you get on with it.

Re: [M100] Xbee and m100
Hey guys, I maintain a rather large (building wide) Zigbee network with some sensors for data collection. We are using the 900Mhz Zigbee Pro modules and it works pretty well. Digi makes a device called a point manager that acts as a bridge between Ethernet or serial. I've used a few hooked to the M100 as wireless modems and they work pretty well. The only downside is cost. Not to change the subject but recently I've gotten into the ESP8266 WiFi modules. Posted about them a while back on here. They are basically $4 wifi to UART devices with some GPIO ports and programming capability. I put one with a Lipo battery inside one of my M100s. I used the Originate Anser switch on the side as a power switch, wired in the LIPO charger circuit to the DC jack and hooked the battery low light to the full charge indicator. I soldered the TX/RX wires directly onto the UART inside the M100 since it has TTL levels. This also lets me continue to use the serial port on the back when the ESP8226 module is off. Works pretty well. You use AT commands to connect to other network devices. For example to "telnet" to my home linux machine I type ATDT192.168.1.82 from the terminal and I'm in. Just another cheaper than Xbee option to consider that uses an already established medium like WiFi.

Re: [M100] Xbee and m100
Nothing more than a couple of (somewhat legible) diagrams. We drew up a convoluted system that relied on an antenna rotator, directional antenna, GPS, and a bunch of cron jobs in Linux. I might add, none of us really know what we're doing, radio-wise, we were going to learn on-the-fly ;) Can't remember what the GPS was for, though. Probably made sense after a few beers...

See, I knew I couldn't be the only person who started scheming like that when I found out the theoretical range on these modules. Did you ever get any further than considering/discussing?

We also considered an XBee uucp network as well, which could have been implemented natively on a number of machines of vintage, although I'm not aware of any such thing for the Model T.

Re: [M100] Xbee and m100
Yeah, I was expecting that the whip would give me a significantly reduced range. I'm going to order some and experiment. It'd be really neat to hack a system like this together. 5 miles is my target (which would be 1/8 of the max point-to-point range. My concern is that I might be able to get 5 miles omni-LOS, but that without a clear line of sight I'd be down to half a mile or so.

Re: [M100] Xbee and m100
Some friends and I considered starting a Fido-style Xbee bbs network and Raspberry Pi SBCs, but as with everything we do, we lost interest when we ran out of beer. An adhoc network of Model Ts would be a neat idea.

Re: [M100] Xbee and m100
The challenge in your project would probably be the antenna; it's largely the 'directional' aspect of the antenna that gives you the point-to-point distance and an omnidirectional whip would give you a drastically shorter range. Antenna height and any obstacles in the path are also major factors affecting distance.
