Wireless connection with 2 mile range? Radio Modem?
I'd like to get telemetry set up in my race car next season. I need a wireless link from a data logger or carPC in the race car to a laptop in the pits about 1-2 miles away. 3G tethering won't work so well since 3G isn't available at all tracks. Most of them are out in the middle of nowhere. Neither computer needs to be connected to the internet. Just one computer to the other.
Someone on another forum mentioned radio modems but didn't have any more info to contribute. I found old Motorola RS232 RF modems out of police cruisers on eBay that are cheap. Would this work? I'm not sure what else I'd need. It would be great if I could find one that does voice and data.
