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. There's a pretty active long distance WiFi community out there; here's a pair of Linksys WRT54Gs communicating over 300+ km: http://ci-journal.net/index.php/ciej/article/view/487/402 Worth experimenting! m ----- Original Message ----- From: Andrew Roach To: Model 100 Discussion Sent: Monday, April 27, 2015 12:19 PM Subject: [M100] Xbee and m100 I have been reading about the Xbee Xtend 900MHz Pro. This is a wireless serial modem with a transmission range of up to 40 miles LOS (with a high gain directional antenna) I'm not super familiar with RF, but I know there are a fair number of Ham guys on the group. If I was to build the proper circuits to connect the Xbee to my PC and my m100, with an omnidirectional whip antenna, could I conceivably be broadcasting a serial connection to a bubble of 5 miles, or so, around my home? Does that sound possible? If it is possible, then would it also be conceivable that I could concoct some kind of router at the receiving end, and have other people sharing this connection using m100s and HP-200LXs connected to these xbee modules? My mind is all aflutter.
